NR341 Pharmacology Study Guide
Part 1: Pharmacology Study Guide
Key Pharmacology Concepts:
1. Drug Classifications:
- Beta Blockers (e.g., metoprolol): Reduce heart rate and BP. Monitor HR/BP.
- ACE Inhibitors (e.g., lisinopril): Risk of cough, hyperkalemia, angioedema.
- Diuretics (e.g., furosemide): Monitor electrolytes (esp. K+), I/O, BP.
2. Insulins:
- Rapid-acting (e.g., lispro): Onset 15 min. Give with food.
- Regular insulin: Peaks in 2-3 hrs. Monitor for hypoglycemia.
- Long-acting (e.g., glargine): No peak. Do not mix with other insulins.
3. Antidepressants:
- SSRIs (e.g., paroxetine): Risk of serotonin syndrome. Avoid St. John's Wort.
- MAOIs: Avoid tyramine (risk of hypertensive crisis).
4. Pain Medications:
- Opioids (e.g., morphine): Risk of respiratory depression, constipation. Monitor RR.
- NSAIDs: Risk of GI bleeding, renal issues.
5. Emergency Meds:
- Epinephrine: For anaphylaxis. Monitor HR/BP.
- Naloxone: Opioid overdose antidote.
