D027 Cardiovascular & Endocrine Review Q&A for Midterm Study

The D027 Cardiovascular & Endocrine Review Q&A covers high-yield concepts students should understand for midterm preparation, including cardiovascular and endocrine medications, diabetes, thyroid disorders, respiratory conditions, neurologic disorders, pain management, mental health, genetics, aging, pediatrics, and immunization. The most important exam strategy is to connect each medication or condition with its adverse effects, contraindications, interactions, monitoring requirements, patient teaching, and appropriate clinical response. Because clinical recommendations can change, students should compare study materials with current evidence-based guidelines.

Cardiovascular Review Questions and Answers

What is the most common adverse effect of ACE inhibitors?

Answer: A dry, persistent cough.

ACE inhibitors such as lisinopril can cause a persistent, nonproductive cough. This adverse effect is associated with increased bradykinin levels. If the cough becomes persistent or bothersome, the healthcare provider may consider an alternative medication, such as an angiotensin II receptor blocker (ARB).

What should patients taking spironolactone know about potassium?

Answer: Avoid potassium supplements unless specifically prescribed.

Spironolactone is a potassium-sparing diuretic that can increase serum potassium levels. The risk of hyperkalemia is particularly important in patients with impaired kidney function or those taking other medications that increase potassium.

Patients should also avoid potassium-containing salt substitutes unless their healthcare provider recommends them.

What should a pregnant patient taking an ACE inhibitor do?

Answer: Contact the healthcare provider promptly.

ACE inhibitors can cause serious fetal complications and are generally avoided during pregnancy. Potential complications include fetal kidney dysfunction, oligohydramnios, fetal skull abnormalities, and neonatal problems.

A patient who becomes pregnant while taking an ACE inhibitor should promptly contact the prescribing clinician so the medication regimen can be reassessed.

Why may metoprolol be combined with nifedipine?

Answer: Metoprolol can help reduce reflex tachycardia.

Nifedipine is a dihydropyridine calcium channel blocker that relaxes vascular smooth muscle and can sometimes produce reflex tachycardia. Metoprolol, a beta blocker, slows the heart rate and may help counter this response.

The combination must be individualized because both medications can lower blood pressure, and beta blockers have their own contraindications and precautions.

How can patients reduce orthostatic hypotension caused by vasodilators?

Answer: Change positions slowly and avoid standing suddenly.

Vasodilators can lower blood pressure and cause dizziness when a patient changes position. Patients should move gradually from lying to sitting and from sitting to standing.

Adequate hydration, when medically appropriate, and fall-prevention strategies can also help reduce injury risk.

Which lifestyle changes can help prevent or manage hypertension?

Answer: Reduce sodium intake, maintain a healthy weight, exercise regularly, moderate alcohol intake, and avoid tobacco.

Lifestyle modification is an important part of blood pressure management. A heart-healthy dietary pattern such as the DASH diet, regular physical activity, weight management, and tobacco avoidance can contribute to improved cardiovascular health.

Family history and other risk factors can also influence an individual’s risk of hypertension.

Which medications can improve outcomes after myocardial infarction?

Answer: ACE inhibitors and beta blockers are commonly used when clinically appropriate.

Evidence-based cardiovascular medications can reduce complications and mortality after myocardial infarction in appropriate patients. Treatment depends on factors such as left ventricular function, blood pressure, kidney function, comorbidities, and medication tolerance.

Which two medication classes can have similar effects on cardiac conduction?

Answer: Beta blockers and nondihydropyridine calcium channel blockers.

Beta blockers and nondihydropyridine calcium channel blockers such as verapamil and diltiazem can slow heart rate and atrioventricular-node conduction. They can also reduce myocardial contractility.

Because of these effects, combining certain medications from these classes requires careful clinical consideration.

What symptom is concerning when a patient taking simvastatin is prescribed azithromycin?

Answer: New muscle pain, tenderness, or weakness.

New or unexplained muscle symptoms in a patient taking a statin should be evaluated. Statin-associated muscle injury can occasionally become severe and lead to rhabdomyolysis and acute kidney injury.

When a new medication is prescribed, healthcare professionals should review potential drug interactions with existing medications.

What treatment may be used for significant warfarin-associated bleeding?

Answer: Vitamin K plus additional reversal therapy when indicated.

Treatment of excessive warfarin anticoagulation depends on the INR, severity of bleeding, location of bleeding, and clinical circumstances.

Serious or life-threatening bleeding may require intravenous vitamin K together with a rapid-acting replacement product such as four-factor prothrombin complex concentrate (PCC).

Endocrine Review Questions and Answers

What short-term complications should be assessed in a newly diagnosed patient with diabetes?

Answer: Hyperglycemia, hypoglycemia, and diabetic ketoacidosis (DKA).

Acute glucose-related complications can develop rapidly and require prompt recognition. Chronic diabetes complications, including neuropathy, kidney disease, and vascular disease, generally develop over a longer period.

Which insulin can be used for rapid correction of premeal hyperglycemia?

Answer: Rapid-acting insulin such as insulin lispro.

Rapid-acting insulin analogs include lispro, aspart, and glulisine. They begin working relatively quickly and are commonly administered around meals according to the patient’s prescribed insulin plan.

What dietary strategy is important for many patients with type 1 diabetes?

Answer: Carbohydrate counting.

Carbohydrate counting helps patients coordinate food intake with insulin administration. Nutrition plans should be individualized according to insulin therapy, activity level, glucose targets, nutritional requirements, and overall health.

Which laboratory test estimates average blood glucose over approximately three months?

Answer: Hemoglobin A1C (HbA1c).

HbA1c reflects average blood glucose exposure over approximately the previous two to three months. However, conditions that alter red blood cell survival or turnover can affect its accuracy.

How is insulin glargine generally administered?

Answer: It is generally administered once daily at a consistent time according to the prescribed regimen.

Insulin glargine is a long-acting basal insulin that provides relatively consistent glucose-lowering activity. It is not designed to provide rapid mealtime glucose control.

What medication may be included in the treatment of thyroid storm?

Answer: Propylthiouracil (PTU) may be used as part of the treatment regimen.

Thyroid storm is a medical emergency associated with severe thyrotoxicosis. Treatment generally involves multiple interventions, which may include a thionamide such as PTU, beta blockade when appropriate, corticosteroids, supportive care, and treatment of the underlying trigger.

Which findings are characteristic of hypothyroidism?

Answer: Bradycardia, cold intolerance, fatigue, and low body temperature.

Hypothyroidism slows metabolic processes throughout the body. Other possible findings include dry skin, constipation, weight changes, and reduced energy.

Why is hypothyroidism important to treat during pregnancy?

Answer: Adequate maternal thyroid hormone is important for fetal development.

Thyroid hormone plays an important role in fetal brain and physical development. Untreated maternal hypothyroidism can negatively affect pregnancy and fetal outcomes.

Levothyroxine is the standard thyroid hormone replacement therapy and is used during pregnancy when clinically indicated.

How does radioactive iodine treat Graves disease?

Answer: Radioactive iodine is taken up by thyroid tissue and destroys thyroid cells, reducing thyroid hormone production.

Radioactive iodine is an established treatment for Graves disease and other forms of hyperthyroidism. Patients receive individualized radiation-safety instructions.

A common long-term outcome is hypothyroidism, which can be treated with thyroid hormone replacement.

Respiratory Review Questions and Answers

How do H1 antihistamines work?

Answer: They block H1 histamine receptors and reduce histamine-related symptoms.

H1 antihistamines reduce the effects of histamine by blocking H1 receptors. First-generation antihistamines are more likely to cause sedation because they cross the blood-brain barrier more readily.

Many second-generation antihistamines cause less sedation and are commonly used for allergic rhinitis.

What should patients taking hydroxyzine know?

Answer: Avoid alcohol and other central nervous system depressants unless specifically approved by the healthcare provider.

Hydroxyzine can cause significant sedation. Combining it with alcohol, opioids, sedatives, or other central nervous system depressants can increase drowsiness, impairment, and safety risks.

What is important when using a metered-dose inhaler?

Answer: Correct inhaler technique and appropriate timing between puffs are essential.

Patients should coordinate inhaler activation with inhalation and follow the instructions for their specific device. A spacer can improve medication delivery for many patients using a pressurized metered-dose inhaler.

How should long-acting beta2 agonists be used in asthma?

Answer: LABAs should be used as part of an ICS-containing regimen rather than as asthma monotherapy.

Long-acting beta2 agonists provide prolonged bronchodilation but do not adequately treat the underlying airway inflammation associated with asthma.

Current asthma treatment strategies emphasize inhaled corticosteroid-containing therapy.

Which medication provides rapid bronchodilation?

Answer: An inhaled short-acting bronchodilator can provide rapid symptom relief when appropriate.

Short-acting beta2 agonists such as albuterol have traditionally been used as rescue medications. However, contemporary asthma recommendations increasingly emphasize inhaled corticosteroid-containing reliever strategies for appropriate patients.

What is the role of inhaled corticosteroids in asthma?

Answer: They reduce airway inflammation and help prevent asthma exacerbations.

Inhaled corticosteroids are controller medications rather than immediate rescue treatments. Patients should understand the difference between their long-term controller medication and their symptom-relief medication.

What is the purpose of guaifenesin?

Answer: Guaifenesin is an expectorant that helps loosen respiratory mucus.

Guaifenesin increases respiratory secretions and may make mucus easier to cough up. It supports productive coughing rather than primarily suppressing the cough reflex.

When are oral antihistamines useful for seasonal allergies?

Answer: They may be useful when taken according to medication directions during allergen exposure.

Second-generation antihistamines are commonly preferred for allergic rhinitis because they generally cause less sedation than first-generation antihistamines.

Which bronchodilators are commonly used for stable COPD maintenance?

Answer: Long-acting inhaled bronchodilators are commonly used for maintenance therapy.

COPD maintenance therapy may include a long-acting beta2 agonist (LABA), long-acting muscarinic antagonist (LAMA), or combination treatment.

Medication selection depends on symptoms, exacerbation history, response to treatment, and individual patient characteristics.

Neurologic and Musculoskeletal Review Questions and Answers

Why is epinephrine the first-line medication for anaphylaxis?

Answer: Epinephrine counteracts several life-threatening effects of anaphylaxis through alpha- and beta-adrenergic activity.

Intramuscular epinephrine is the first-line treatment for anaphylaxis. It can produce vasoconstriction, increase blood pressure, reduce airway swelling, promote bronchodilation, and support cardiovascular function.

How should the first dose of an alpha-adrenergic antagonist be administered?

Answer: The first dose is often taken at bedtime.

Alpha-adrenergic antagonists can produce a significant first-dose effect, including dizziness, orthostatic hypotension, and fainting. Taking the initial dose at bedtime can reduce the risk of falls and injury.

What may cause dyskinesias in a patient taking levodopa/carbidopa?

Answer: Long-term levodopa treatment can cause dyskinesias.

Involuntary movements may occur as a complication of Parkinson disease treatment with levodopa. If dyskinesias become troublesome, the prescriber may modify the dose, timing, or medication regimen.

What are important risk factors for Alzheimer disease?

Answer: Advancing age and family history are important risk factors.

Age is a major risk factor for Alzheimer disease. Genetic factors can also affect susceptibility. However, having a family history does not mean that an individual will definitely develop the condition.

What should patients taking phenytoin know about oral contraceptives?

Answer: Phenytoin can reduce the effectiveness of some hormonal contraceptives.

Phenytoin is an enzyme-inducing antiseizure medication that can increase the metabolism of certain hormonal contraceptives. Patients should discuss reliable contraceptive options with their healthcare professional.

What laboratory monitoring may be needed with certain antiseizure medications?

Answer: Serum drug concentrations may be monitored when therapeutic drug monitoring is clinically appropriate.

Some antiseizure medications have established therapeutic ranges. Drug concentrations can help evaluate adherence, toxicity, interactions, and whether drug exposure is within the expected range.

When should aspirin be discontinued before surgery?

Answer: The timing depends on the reason for aspirin therapy, bleeding risk, and type of surgery.

Aspirin irreversibly affects platelet function, so its antiplatelet effect can persist for the lifespan of affected platelets. Patients should not stop prescribed aspirin independently, particularly when it is being used for cardiovascular protection.

The prescribing and surgical teams should determine whether aspirin should be continued or temporarily withheld.

How can long-term glucocorticoid therapy affect bone health?

Answer: Long-term glucocorticoid therapy increases the risk of osteoporosis and fractures.

Glucocorticoids can reduce bone formation, decrease calcium absorption, and increase bone resorption. Depending on individual risk, patients may need fracture-risk assessment, exercise, fall prevention, nutritional optimization, and osteoporosis treatment.

Why is methotrexate started early in rheumatoid arthritis?

Answer: Methotrexate is a disease-modifying antirheumatic drug (DMARD) that can slow disease progression and reduce joint damage.

NSAIDs and corticosteroids may reduce pain and inflammation, but they do not provide the same disease-modifying effects as DMARDs.

Early treatment can help control rheumatoid arthritis and reduce progressive joint damage.

What treatment may be considered for recurrent gout?

Answer: Urate-lowering therapy may be appropriate for recurrent or clinically significant gout.

Allopurinol and febuxostat are examples of urate-lowering medications. Acute gout attacks are managed differently and may involve NSAIDs, colchicine, or corticosteroids depending on patient-specific factors.

Hormonal, Gastrointestinal, and Genitourinary Review

What are the primary benefits of menopausal hormone therapy?

Answer: Hormone therapy can effectively treat vasomotor symptoms and help prevent bone loss in appropriate patients.

Hormone therapy should be individualized according to age, time since menopause, symptoms, medical history, risks, and treatment goals.

Patients with an intact uterus generally need a progestogen with systemic estrogen to reduce the risk of endometrial hyperplasia and cancer.

Who may need estrogen-only rather than combined estrogen-progestogen therapy?

Answer: A patient who has had a hysterectomy may generally use estrogen-only systemic therapy when hormone therapy is otherwise appropriate.

When the uterus is present, systemic estrogen is generally combined with a progestogen to protect the endometrium.

After hysterectomy, a progestogen is often unnecessary unless another clinical indication exists.

What is the treatment goal of terazosin in benign prostatic hyperplasia (BPH)?

Answer: To improve lower urinary tract symptoms and urinary flow.

Terazosin is an alpha-1 adrenergic antagonist. It relaxes smooth muscle in the prostate and bladder neck, which can improve urinary hesitancy and difficulty with urine flow.

It improves symptoms but does not primarily shrink the prostate.

What teaching is essential when metronidazole is prescribed?

Answer: Patients should follow medication-specific instructions regarding alcohol avoidance during treatment and after the final dose.

Patients taking metronidazole should follow the prescribing information and their healthcare provider’s instructions concerning alcohol.

Other possible adverse effects include gastrointestinal symptoms and a metallic taste.

How should bulk-forming laxatives be taken?

Answer: Take them with adequate fluid.

Bulk-forming laxatives such as psyllium absorb water and increase stool bulk. Adequate fluid intake helps these medications work effectively and reduces the risk of complications such as obstruction.

Why should loperamide generally be avoided in certain infectious diarrheas?

Answer: Slowing intestinal movement may delay elimination of pathogens and increase complications in some infections.

Patients with bloody diarrhea, high fever, severe abdominal pain, or suspected invasive infection should seek medical evaluation instead of relying on antimotility medications.

What is an important interaction between TMP-SMX and glipizide?

Answer: TMP-SMX can increase the risk of hypoglycemia in patients taking sulfonylureas such as glipizide.

Patients receiving both medications may require closer blood glucose monitoring and medication review. Patients should also know how to recognize symptoms of hypoglycemia and respond appropriately.

What is a common treatment option for uncomplicated cystitis?

Answer: Appropriate short-course antibiotic therapy may be used when bacterial cystitis is suspected or confirmed.

Antibiotic selection depends on current guidelines, allergies, kidney function, patient characteristics, and local antimicrobial resistance patterns.

Depending on the clinical situation, options may include nitrofurantoin, trimethoprim-sulfamethoxazole, or fosfomycin.

What medications treat genital herpes?

Answer: Antiviral medications such as acyclovir and valacyclovir.

Antiviral therapy can decrease the severity and duration of genital herpes symptoms. Suppressive therapy may reduce outbreak frequency and transmission risk, although antiviral medications do not eradicate latent herpes simplex virus.

Lipid Management and Heart Failure Review

Which medication is commonly used for significant LDL cholesterol elevation and elevated ASCVD risk?

Answer: Statins are generally first-line pharmacologic therapy when indicated.

Statins reduce LDL cholesterol and cardiovascular risk. The appropriate intensity depends on factors such as age, LDL level, diabetes, established cardiovascular disease, and overall ASCVD risk.

How has treatment of heart failure with reduced ejection fraction evolved?

Answer: Guideline-directed medical therapy commonly includes four major medication classes.

For appropriate patients with HFrEF, contemporary therapy commonly includes:

• An ARNI, ACE inhibitor, or ARB

• An evidence-based beta blocker

• A mineralocorticoid receptor antagonist

• An SGLT2 inhibitor

Sacubitril/valsartan may be used instead of an ACE inhibitor or ARB in appropriate patients. Treatment is individualized according to blood pressure, kidney function, potassium levels, comorbidities, and medication tolerance.

Population Health and Genetics Review

What is incidence?

Answer: Incidence measures new cases of a disease occurring in a population during a specified period.

Incidence helps researchers determine how frequently new cases develop. It can also be used to evaluate changes in disease risk over time.

What is prevalence?

Answer: Prevalence measures the proportion of a population living with a disease or condition at a specific time or during a specified period.

Unlike incidence, prevalence includes existing cases. It is influenced by the occurrence of disease as well as how long people live with the condition.

What is relative risk?

Answer: Relative risk compares disease incidence between an exposed group and an unexposed group.

A relative risk greater than 1 indicates a higher incidence in the exposed group, while a value below 1 indicates a lower incidence.

Relative risk is commonly used in epidemiologic studies to examine associations between exposures and health outcomes.

What does multifactorial inheritance mean?

Answer: Multifactorial traits result from interactions among multiple genes and environmental factors.

Many common health conditions do not result from a single gene. Instead, multiple genetic and environmental factors may contribute to disease risk.

Examples include hypertension, type 2 diabetes, obesity, coronary artery disease, and some cancers.

What is a gene-environment interaction?

Answer: It occurs when genetic susceptibility and environmental factors interact to influence disease risk.

A family history can indicate increased susceptibility without determining whether a person will develop a condition. Diet, physical activity, environmental exposures, stress, and other factors can influence disease expression.

How can family and twin studies help researchers understand disease?

Answer: They help estimate the relative contributions of genetic and environmental factors.

Monozygotic twins share nearly all of their genetic material, whereas dizygotic twins share approximately half of their segregating genetic material.

Comparing similarities and differences between twin pairs can provide information about heritable characteristics and environmental influences.

Health Disparities, Culture, and Complementary Therapies

What factors contribute to health disparities?

Answer: Social, economic, environmental, healthcare-system, and access-related factors can contribute to differences in health outcomes.

Health disparities are influenced by multiple interconnected factors. These may include affordability, healthcare access, geographic location, health literacy, communication barriers, quality of care, discrimination, and other social determinants of health.

How can healthcare professionals improve health literacy?

Answer: Use plain language, confirm understanding, encourage questions, and provide information in the patient’s preferred language when appropriate.

Health information should be understandable and actionable. The teach-back method is particularly useful because it allows healthcare professionals to determine whether patients can explain instructions in their own words.

What are the three domains of the PEN-3 cultural model?

Answer: Cultural identity, relationships and expectations, and cultural empowerment.

The PEN-3 model provides a framework for understanding cultural influences on health behaviors and developing culturally responsive health interventions.

What should nurses consider when patients use complementary therapies?

Answer: Ask about all supplements and complementary therapies and evaluate their safety, evidence, interactions, and adverse effects.

Patients may not consider herbal products or supplements to be medications. Nurses should therefore ask specifically about their use.

Some complementary products can cause significant adverse effects or interact with prescription medications. For example, kava has been associated with serious liver injury, while some red yeast rice products contain compounds related to lovastatin.

Aging and Pediatric Health Review

What cardiovascular change is commonly associated with aging?

Answer: Increased arterial stiffness can contribute to higher blood pressure and cardiovascular changes.

Aging can reduce vascular compliance and contribute to changes in blood pressure and cardiac function. However, new cardiovascular symptoms should not automatically be considered a normal consequence of aging and require appropriate evaluation.

What endocrine changes occur with aging?

Answer: Aging can affect thyroid, pancreatic, adrenal, reproductive, and other endocrine systems.

Age-related endocrine changes may influence metabolism, body composition, glucose regulation, energy levels, and reproductive hormone concentrations.

What contributes to anorexia of aging?

Answer: Reduced appetite, altered taste and smell, hormonal changes, lower energy requirements, and social or medical factors can contribute.

Older adults may have lower calorie requirements while remaining vulnerable to inadequate nutrition. Chronic illness, medication effects, oral health problems, depression, social isolation, and difficulty obtaining food may further contribute to poor nutritional intake.

What causes menopausal hot flashes?

Answer: Changes in ovarian hormone production, particularly declining estrogen levels, contribute to vasomotor symptoms.

During the menopausal transition, changes in estrogen can affect the body’s thermoregulatory system. This may produce sudden episodes of warmth, flushing, and sweating.

What is the most common childhood cancer?

Answer: Leukemia is the most commonly diagnosed cancer in children.

Childhood cancer is uncommon compared with cancer in adults, but leukemia represents a major category of pediatric malignancy.

Advances in diagnosis and treatment have substantially improved survival for many childhood cancers.

What is an important long-term concern after childhood cancer treatment?

Answer: Survivors may experience late effects associated with the disease or its treatment.

Late effects vary according to the cancer type and treatment received. Possible effects can involve endocrine, cardiovascular, neurologic, reproductive, psychosocial, and other systems.

How should hypertension in children be evaluated?

Answer: Evaluation may include repeated blood pressure measurements, ambulatory monitoring when appropriate, lifestyle assessment, and evaluation for secondary causes or target-organ effects.

Pediatric blood pressure must be interpreted using age-, sex-, and height-appropriate standards.

Treatment may include lifestyle interventions and medication when clinically indicated.

How is asthma supported by objective testing in an older child?

Answer: Spirometry demonstrating variable expiratory airflow limitation can support the diagnosis.

A family history of asthma, atopy, elevated IgE, or eosinophilia may provide supporting information, but these findings do not independently establish an asthma diagnosis.

What is a characteristic feature of cystic fibrosis?

Answer: Thick, sticky mucus is a defining feature of cystic fibrosis.

Cystic fibrosis affects multiple organ systems, particularly the respiratory and gastrointestinal systems. Patients can develop recurrent respiratory infections, pancreatic insufficiency, nutritional problems, and cystic-fibrosis-related diabetes.

Medication Safety in Infants and Older Adults

Why may newborns require lower medication doses?

Answer: Immature hepatic and renal systems can alter medication metabolism and elimination.

Newborns have developing pharmacokinetic systems. Certain medications may therefore remain in the body longer or reach higher concentrations, increasing the risk of adverse effects and toxicity.

Why are infants particularly vulnerable to medication toxicity?

Answer: Immature hepatic metabolism, renal elimination, protein binding, and other physiologic systems can alter drug effects.

Medication dosing in infants requires careful consideration of developmental differences. Drugs with narrow therapeutic ranges require especially careful dosing and monitoring.

What should a nurse assess when an older adult has a subtherapeutic medication level?

Answer: Assess medication adherence before assuming the dose should be increased.

The nurse should assess missed doses, medication schedules, adverse effects, cost barriers, access to medications, and the patient’s understanding of the treatment plan.

Increasing the dose without identifying the cause of the low drug level could increase toxicity if the patient subsequently resumes consistent medication use.

What is an important measure of kidney function in older adults taking multiple medications?

Answer: Estimated kidney function, such as eGFR or creatinine clearance when appropriate, should be considered.

Serum creatinine alone may not accurately reflect kidney function in some older adults because creatinine production is influenced by muscle mass.

Kidney function is particularly important when determining appropriate doses for medications that are primarily eliminated through the kidneys.

What complications can occur with excessive caffeine intake?

Answer: Severe caffeine toxicity can cause agitation, tremors, tachycardia, hypertension, and seizures.

Large amounts of caffeine, especially concentrated caffeine products, can cause significant cardiovascular and neurologic stimulation. Severe toxicity requires urgent medical evaluation.

What baseline information is important before starting methylphenidate in a child?

Answer: Height, weight, appetite, cardiovascular history, blood pressure, and heart rate should be assessed.

Methylphenidate can affect appetite and growth and may produce cardiovascular effects. Growth and cardiovascular parameters should therefore be monitored during treatment.

Why are sedating cough medicines generally not recommended for young infants?

Answer: Young children are particularly vulnerable to serious adverse effects and central nervous system depression from certain cough and cold medications.

Many over-the-counter cough and cold products are not recommended for young children. Parents and caregivers should consult a pediatric healthcare professional before administering these products to infants or young children.

Immunization Review Questions and Answers

Where is the hepatitis B vaccine administered in infants?

Answer: The anterolateral thigh is the preferred intramuscular injection site for infants.

The vastus lateralis muscle provides an appropriate intramuscular vaccination site during infancy. Vaccine administration should follow current immunization recommendations and age-appropriate injection techniques.

Which vaccine type may be contraindicated in significantly immunocompromised children?

Answer: Certain live vaccines, such as varicella vaccine, may be contraindicated depending on immune status.

Live vaccines may pose risks to patients with significant immunosuppression. Vaccination decisions should be individualized according to the child’s immune condition and current immunization guidance.

Medication Adverse Effects and Clinical Priorities

Which antihypertensive medication commonly causes a persistent dry cough?

Answer: Lisinopril and other ACE inhibitors.

A persistent dry cough is a classic adverse effect associated with ACE inhibitors. ARBs generally cause this type of cough much less frequently.

Which postoperative complaint requires priority assessment after IV morphine?

Answer: A spreading rash or reaction around the IV site requires prompt assessment.

The nurse should immediately assess the IV site and the patient’s overall condition for possible infiltration, phlebitis, tissue injury, or a systemic hypersensitivity reaction.

If an allergic reaction is suspected, respiratory status and vital signs should also be assessed promptly.

Which patient should receive priority assessment?

Answer: The patient with the greatest acuity, instability, risk of deterioration, or immediate safety concern should receive priority.

Age alone should not determine nursing priority. When several patients appear stable, the nurse should identify which patient has the greatest risk of an acute complication and perform a focused assessment.

Pain Management Review Questions and Answers

Where does conscious pain perception occur?

Answer: Conscious pain perception involves processing in the cerebral cortex and interconnected central nervous system structures.

Pain is a complex experience involving sensory, emotional, cognitive, and behavioral components. Multiple neural pathways and brain regions participate in pain processing.

What type of pain warns of actual or potential tissue injury?

Answer: Acute pain.

Acute pain generally serves a protective function and is associated with actual or potential tissue injury.

Chronic pain persists beyond expected healing and can involve complex biological, psychological, and social factors.

How do endogenous opioids reduce pain?

Answer: Endogenous opioids such as endorphins and enkephalins bind to opioid receptors and reduce pain signaling.

These naturally occurring substances influence pain transmission in the central and peripheral nervous systems by activating opioid receptors and inhibiting pain pathways.

What adverse effect after lidocaine with epinephrine requires attention?

Answer: Significant nervousness, palpitations, or tachycardia require assessment.

Epinephrine can temporarily stimulate the cardiovascular system. Pronounced nervousness, palpitations, tachycardia, or other concerning symptoms may indicate excessive systemic absorption or an adverse reaction.

How should a transdermal buprenorphine patch be managed?

Answer: Apply it according to the prescribed schedule and rotate application sites.

Rotating sites can reduce local skin irritation. Patients should follow the specific product instructions regarding placement, replacement, heat exposure, and disposal.

What are classic signs of opioid toxicity?

Answer: Respiratory depression, decreased level of consciousness, and pinpoint pupils.

Severe opioid toxicity can cause life-threatening respiratory depression. Immediate assessment and intervention are required.

Naloxone may be administered when indicated, along with appropriate airway and ventilatory support.

When should sumatriptan be avoided?

Answer: It should be avoided in patients with certain cardiovascular conditions, including established coronary artery disease.

Sumatriptan and other triptans can cause vasoconstriction. Patients with specific cardiovascular contraindications should not use these medications unless a qualified healthcare professional determines that treatment is appropriate.

Which headache may respond rapidly to supplemental oxygen?

Answer: Cluster headache.

High-flow oxygen is an established acute treatment for cluster headaches in appropriate patients. Other acute and preventive therapies may also be considered based on the patient’s condition.

Is acupuncture effective for cancer pain?

Answer: Acupuncture may be considered as a complementary therapy, although evidence varies by condition and clinical context.

Acupuncture should not automatically replace evidence-based cancer pain treatment. Complementary therapies should be discussed with the oncology team and incorporated safely into an individualized pain-management plan.

What is appropriate for severe cancer pain?

Answer: Opioid analgesics are an important treatment option for moderate-to-severe cancer pain.

Cancer pain treatment should be individualized according to pain severity, cause, previous opioid exposure, kidney and liver function, adverse effects, and patient goals.

Nonopioid medications and nonpharmacologic interventions can also be incorporated when appropriate.

Mental Health Review: Schizophrenia and Mood Disorders

What are the major symptom categories of schizophrenia?

Answer: Positive, negative, and cognitive symptoms.

Positive symptoms include hallucinations and delusions. Negative symptoms can include reduced emotional expression, reduced motivation, and social withdrawal.

Cognitive symptoms may affect attention, memory, processing speed, and executive functioning.

How is schizophrenia treated?

Answer: Treatment commonly combines antipsychotic medication with psychosocial interventions and supportive care.

First-generation and second-generation antipsychotics have different receptor activity and adverse-effect profiles.

Treatment should be individualized according to symptoms, response, adverse effects, patient preferences, and treatment goals. Psychosocial interventions can support functioning, adherence, and recovery.

What characterizes major depressive disorder?

Answer: Major depressive disorder involves persistent depressed mood or loss of interest accompanied by additional symptoms that cause clinically significant distress or impairment.

Possible symptoms include sleep disturbances, appetite or weight changes, fatigue, impaired concentration, feelings of worthlessness or guilt, psychomotor changes, and suicidal thoughts.

Diagnosis requires a comprehensive assessment using established diagnostic criteria.

How does bipolar disorder differ from major depressive disorder?

Answer: Bipolar disorder includes episodes of mania or hypomania, with or without depressive episodes.

The presence of mania or hypomania distinguishes bipolar disorders from major depressive disorder.

Treatment depends on the specific bipolar disorder and current phase and may include mood stabilizers or certain atypical antipsychotics. Antidepressant monotherapy may not be appropriate for some patients with bipolar disorder.

Anxiety, PTSD, and OCD Review

What is a common complication associated with panic disorder?

Answer: Agoraphobia can occur with panic disorder.

Agoraphobia involves significant fear or avoidance of situations where a person believes escape may be difficult or help may not be available.

It can occur alongside recurrent panic attacks.

How long must excessive worry persist for generalized anxiety disorder?

Answer: At least six months.

Generalized anxiety disorder involves excessive, difficult-to-control worry about multiple areas of life for at least six months.

Associated symptoms may include restlessness, fatigue, irritability, muscle tension, and sleep disturbances.

What is a common treatment approach for generalized anxiety disorder?

Answer: Cognitive behavioral therapy and medications such as SSRIs or SNRIs are commonly used.

Treatment should be individualized according to symptom severity, comorbidities, patient preferences, and treatment response.

Buspirone is another medication option and does not have the same dependence profile as benzodiazepines.

What is the significance of recurrent nightmares after trauma?

Answer: Recurrent nightmares may indicate trauma-related re-experiencing and should prompt assessment for PTSD or another trauma-related disorder.

Healthcare professionals should sensitively assess trauma history and other symptoms. Nightmares should be considered alongside the person’s complete clinical presentation.

What is an evidence-based treatment approach for PTSD?

Answer: Trauma-focused psychotherapy is a major component of evidence-based PTSD treatment.

Trauma-focused therapies can help patients process traumatic experiences and develop healthier coping strategies.

Certain medications, including SSRIs, may also be appropriate depending on symptoms, comorbidities, patient preferences, and treatment response.

What characterizes obsessive-compulsive disorder?

Answer: OCD involves recurrent obsessions, compulsions, or both that are time-consuming or cause significant distress or impairment.

Evidence-based treatment includes exposure and response prevention (ERP), a specialized form of cognitive behavioral therapy.

SSRIs are also commonly used. Severe or treatment-resistant OCD may require specialized psychiatric treatment.

Stress and Adaptation Review Questions

How does stress affect immunity?

Answer: Stress hormones, particularly cortisol, can alter immune function.

The stress response involves neuroendocrine pathways that influence inflammatory and immune activity. Chronic or severe stress can have broader effects on immune regulation.

What influences an individual’s stress response?

Answer: The individual’s appraisal of the stressor and ability to cope can strongly influence the response.

People can respond differently to the same stressful event because of differences in previous experiences, coping resources, social support, perceived control, and interpretation of the event.

What causes cold, clammy skin during an acute stress response?

Answer: Sympathetic activation causes peripheral vasoconstriction and sweating.

During an acute stress response, sympathetic nervous system activity can redirect blood flow and stimulate sweat glands. This can produce cool, pale, or clammy skin.

What are the stages of the general adaptation syndrome?

Answer: Alarm, resistance, and exhaustion.

The alarm stage represents the body’s initial response to a stressor. During resistance, the body attempts to adapt to ongoing stress.

If prolonged stress continues without adequate recovery, the body may eventually enter the exhaustion stage.

What hormone contributes to stress-related hyperglycemia?

Answer: Cortisol.

Cortisol increases glucose availability through mechanisms such as stimulation of gluconeogenesis.

Other stress hormones, including epinephrine and norepinephrine, can also contribute to elevated blood glucose during acute stress.

Acute Stress Disorder and PTSD

When can PTSD be diagnosed after trauma?

Answer: PTSD requires symptoms lasting longer than one month after the traumatic event.

Symptoms occurring from three days to one month after trauma may meet criteria for acute stress disorder, depending on the complete clinical presentation.

Persistent symptoms beyond one month may meet criteria for PTSD.

What is an evidence-based treatment approach for acute stress disorder?

Answer: Trauma-focused cognitive behavioral therapy is an important evidence-based treatment approach.

Treatment can help individuals process traumatic experiences and develop effective coping strategies.

Routine psychological debriefing is not recommended as a universal preventive intervention after trauma.

Why is prolonged benzodiazepine use concerning in trauma-related disorders?

Answer: Benzodiazepines can cause dependence, tolerance, sedation, and other adverse effects.

Long-term benzodiazepine use requires careful evaluation. These medications are not routinely recommended as long-term treatment for PTSD and may create additional clinical concerns.

Chronic and Cancer Pain Review

What medication can interact significantly with duloxetine?

Answer: Tramadol can increase the risk of serotonin toxicity when combined with serotonergic medications such as duloxetine.

Tramadol has opioid activity and also affects serotonin and norepinephrine pathways. Combining tramadol with serotonergic medications can increase the risk of serotonin syndrome and other adverse effects.

What should be assessed first in unexplained chronic generalized pain?

Answer: Perform a comprehensive assessment of sleep, physical symptoms, medications, psychosocial factors, and functional status.

Poor sleep can increase pain sensitivity and contribute to fatigue. A broad assessment can help identify potential causes, contributing factors, medication-related problems, and appropriate treatment options.

What is an appropriate intervention for severe pain in a hospice patient?

Answer: Provide timely, appropriately prescribed analgesia while prioritizing comfort and the patient’s goals of care.

Hospice care focuses on comfort, dignity, and quality of life for individuals with advanced illness.

Severe pain should be assessed promptly and treated with an individualized plan that may include opioids and other supportive interventions.

Key D027 Unit 4 Exam Takeaways

For the D027 Unit 4 midterm, focus on recognizing relationships between medications, adverse effects, contraindications, drug interactions, monitoring requirements, and patient education.

High-yield medication and concept associations include:

• ACE inhibitors: Persistent dry cough and important pregnancy-related safety concerns.

• Spironolactone: Potassium retention and hyperkalemia risk.

• Phenytoin: Can reduce the effectiveness of some hormonal contraceptives.

• Opioids: Toxicity can cause respiratory depression, sedation, and pinpoint pupils.

• LABAs: Used within an appropriate ICS-containing asthma treatment regimen.

• Methotrexate: Disease-modifying therapy for rheumatoid arthritis.

• Rapid-acting insulin: Used around meals according to the prescribed regimen.

• Insulin glargine: Long-acting basal insulin.

• Epinephrine: First-line medication for anaphylaxis.

• Sumatriptan: Has important cardiovascular contraindications.

• SSRIs/SNRIs and CBT: Common evidence-based approaches for anxiety and mood disorders.

• ERP: Important behavioral therapy for OCD.

• Trauma-focused psychotherapy: A major evidence-based treatment approach for PTSD.

• Incidence: Measures new cases in a population over a specified period.

• Prevalence: Measures existing cases in a population.

• Relative risk: Compares disease incidence between exposed and unexposed groups.

For exam questions involving medications, avoid memorizing only the drug name. Instead, connect the medication to its mechanism, expected therapeutic effect, major adverse effects, contraindications, interactions, monitoring requirements, and patient teaching.

Also distinguish between acute treatment and long-term management. Clinical recommendations can change as new evidence becomes available, so current professional guidelines should take precedence when older study materials conflict with contemporary practice.
