1. Medications that bind to beta₂ receptors in the lungs causing bronchodilation
Correct Answer: Beta₂ Adrenergic Agonists
2. Examples of Beta₂ Adrenergic Agonists
Correct Answer: Albuterol; Salmeterol
3. First-line rescue inhaler used during severe asthma attacks
Correct Answer: Albuterol
4. Long-acting beta₂ agonist taken every 12 hours, even without symptoms
Correct Answer: Salmeterol
5. Nursing implications for Albuterol
Correct Answer: Shake before use; wait at least 1 minute between puffs;
notify HCP if ineffective after 3 doses
6. Medications such as phenylephrine and pseudoephedrine that cause
vasoconstriction of respiratory mucosa
Correct Answer: Alpha-1 Adrenergic Agonists (Decongestants)
7. Therapeutic use of a medication (what it treats)
Correct Answer: Indication
,8. Primary indication for decongestants
Correct Answer: Rhinitis
9. Contraindications for decongestants
Correct Answer: Hypertension; Coronary artery disease
10. MAOIs are classified as what type of medication?
Correct Answer: Antidepressants (Monoamine Oxidase Inhibitors)
11. Example of a 1st generation antihistamine
Correct Answer: Diphenhydramine
12. Common side effects of 1st generation antihistamines
Correct Answer: Sedation; Anticholinergic effects (dry mouth, constipation,
urinary retention, photosensitivity)
13. Nursing precautions for patients taking 1st generation antihistamines
Correct Answer: Implement fall precautions; advise patient not to drive or
operate heavy machinery
14. Examples of 2nd generation antihistamines
Correct Answer: Loratadine; Cetirizine
15. Key characteristic of 2nd generation antihistamines
Correct Answer: Less sedating than 1st generation
16. First-line medications for hypertension ending in “-pril”
Correct Answer: ACE Inhibitors (e.g., Lisinopril, Captopril)
17. Mechanism of Action of ACE Inhibitors
Correct Answer: Block conversion of angiotensin I to angiotensin II in the
RAAS system, causing vasodilation
, 18. Indications for ACE Inhibitors
Correct Answer: Hypertension; Heart failure; Myocardial infarction; Diabetic
nephropathy
19. Major side effects of ACE Inhibitors
Correct Answer: Angioedema; Cough; Elevated potassium (hyperkalemia);
Hypotension; Dizziness; Renal impairment
20. Nursing implications for ACE Inhibitors
Correct Answer: Monitor BP, pulse, potassium, creatinine; avoid potassium
supplements unless prescribed
21. Serious toxicity associated with ACE Inhibitors
Correct Answer: Fetal toxicity
22. Second-line BP medications ending in “-sartan”
Correct Answer: Angiotensin II Receptor Blockers (ARBs)
23. Primary effect of ARBs
Correct Answer: Lower blood pressure
24. Contraindications for ARBs
Correct Answer: Volume depletion; Bilateral renal artery stenosis;
Angioedema; Pregnancy (2nd/3rd trimester)
25. Nursing considerations for ARBs
Correct Answer: Monitor BP and pulse; assess for angioedema and heart
failure (edema, crackles, dyspnea, weight gain, JVD); instruct patient to rise slowly
and avoid salt substitutes
26. Key assessments for heart failure patients
Correct Answer: Daily weight; peripheral edema; crackles; dyspnea; JVD
