NR 293 Exam 2 Study Guide

This study guide covers key pharmacological classes and their respective exemplars, including drug indications, contraindications, adverse effects, interactions, and patient safety/teaching. The classes and medications to focus on are: Opioids, Non-Opioid Analgesics, Benzodiazepines, Barbiturates, Lipase Inhibitors, CNS Stimulants, Antipsychotics, and various other medications used for conditions such as Parkinson’s disease, anxiety, seizures, and weight management. Understanding these aspects for each drug is critical for clinical application and safe patient care.

Opioid Class II Narcotic

Indications: Used for moderate to severe pain. Contraindications: Should not be used in patients with epilepsy, heart, liver, and kidney disease, or those with allergies. Adverse Effects: Side effects include shortness of breath, edema in lower extremities, constipation, and allergic reactions. Interactions: Avoid MAO inhibitors within 14 days of taking Morphine. Monitoring is necessary when taking vitamins, herbal supplements, or alcohol. Safety/Patient Teaching: Talk to your doctor before taking if pregnant or breastfeeding. Morphine has a high potential for dependence and habit formation.

Non-Opioid Analgesic (Acetaminophen)

Indications: Used for fever and mild to moderate pain. Contraindications: Not recommended for individuals with liver conditions. Adverse Effects: Possible side effects include allergy symptoms, black tarry stools, excessive sweating, and fatigue. Interactions: Monitor prothrombin time (PT/INR) when taken with anticoagulants. Avoid exceeding 3000mg per day in adults, 2000mg in children, and elderly patients. Safety/Patient Teaching: Does not treat inflammation. Avoid alcohol use and inform your healthcare provider if you are pregnant or breastfeeding.

Benzodiazepines Class II Narcotic (Diazepam)

Indications: Primarily used for anxiety, muscle spasms, and seizures. Contraindications: Contraindicated in patients with narrow-angle glaucoma, untreated open-angle glaucoma, myasthenia gravis, or severe liver disease. Adverse Effects: Includes confusion, seizures, drowsiness, nausea, dizziness, and lightheadedness. Interactions: Should not be used with MAO inhibitors, theophylline, or medications for depression and seizures. Safety/Patient Teaching: Avoid alcohol and inform your doctor if pregnant or breastfeeding. Diazepam is habit-forming and poses risks of dependence.

Barbiturates Class IV Narcotic (Phenobarbital)

Indications: Used for controlling seizures and preventing withdrawal symptoms in barbiturate-dependent patients. Contraindications: Avoid use in patients with acute intermittent porphyria, severe liver disease, or respiratory conditions. Adverse Effects: May cause dizziness, drowsiness, headache, loss of appetite, nausea, and vomiting. Interactions: Phenobarbital may interact with other anti-anxiety drugs, depression treatments, and phenytoin (Dilantin). Safety/Patient Teaching: Should not be used during pregnancy or breastfeeding. Patients with a history of depression or suicidal ideations should avoid this drug.

Lipase Inhibitors (Orlistat)

Indications: Used to assist with weight loss and management. Contraindications: Avoid use in patients with a history of allergic reactions to orlistat or those who are pregnant. Adverse Effects: Can cause dark urine, pale stool, yellowing of the skin, back pain, severe stomach pain, nausea, and diarrhea. Interactions: Should not be taken within 3 hours of cyclosporine, or with levothyroxine and multivitamins. Safety/Patient Teaching: Can cause liver damage and may lead to kidney stones. Not safe during pregnancy.

CNS Stimulant (Methylphenidate Hydrochloride)

Indications: Used to treat ADHD and narcolepsy. Contraindications: Avoid in patients with glaucoma, overactive thyroid, muscle tics, or a history of Tourette syndrome. Adverse Effects: May cause changes in vision, chest pain, nausea, sweating, dry mouth, and loss of appetite. Interactions: Avoid combining with certain medications such as guanethidine, phenylbutazone, and certain blood pressure medications. Safety/Patient Teaching: This medication is habit-forming, and should be avoided by individuals with a history of high blood pressure, thyroid problems, or seizures.

Table of Pharmacological Agents and Their Characteristics

Here is the rephrased version of your information formatted in paragraphs and a table with headings. I’ve kept it in APA format and included references at the end.

Indirect Myasthenia Gravis & Alzheimer’s Diagnosis

Conditions such as Myasthenia Gravis and Alzheimer’s disease may cause a variety of symptoms requiring careful medication management. Medications for these conditions should be taken as prescribed and should not be abruptly discontinued. Medications such as anticholinergics, antihistamines, and sympathomimetics may result in side effects like bradycardia, hypotension, and conductivity abnormalities. Toxicity symptoms are often referred to by the acronym SLUDGE (Salivation, Lacrimation, Urinary incontinence, Diarrhea, GI cramps, Emesis), indicating significant side effects that require medical attention.

Direct Glaucoma, Atony, and Neurogenic Bladder

Glaucoma and conditions such as neurogenic bladder (related to atony) are other examples where medications should be monitored closely. Anticholinergics and antihistamines can lead to adverse effects such as increased heart rate, dysrhythmias, and urinary retention. Corticosteroids may be used to manage symptoms but are contraindicated in certain conditions like active untreated infections or gastrointestinal issues. It is important to note that elderly patients are at a higher risk for heat stroke, and adjustments should be made to avoid extreme temperatures and ensure adequate hydration.

Medication Safety and Contraindications

When managing medications for conditions like depression, panic disorder, or social anxiety disorder, patients must understand the importance of monitoring side effects. Medications like SSRIs, MAOIs, and St. John’s Wort can cause side effects including hallucinations, hyponatremia, and urinary retention. These medications should be continued for 4-8 weeks before evaluating their effectiveness. Additionally, patients should be warned about specific contraindications, including drug allergies and the presence of narrow-angle glaucoma.
