Which class of medications are given to liquefy secretions and make them easier to expel?

Mucolytics

Glucocorticoids

Calcium channel blockers

Bronchodilators

Answer and Explanation

The Correct Answer is A

Choice A reason: Mucolytics (e.g., acetylcysteine) break disulfide bonds in mucus, thinning it to ease expectoration, directly aiding secretion clearance in respiratory conditions.

Choice B reason: Glucocorticoids reduce inflammation in airways, not liquefying mucus; they address swelling, not viscosity, so they don’t facilitate expulsion directly.

Choice C reason: Calcium channel blockers relax vascular smooth muscle for hypertension, not affecting mucus consistency or respiratory secretions, irrelevant to this goal.

Choice D reason: Bronchodilators open airways, improving airflow, but don’t alter mucus viscosity, aiding breathing, not secretion liquefaction or removal specifically.

Correct Answer is A

Explanation

Choice A reason: NSTEMI causes chest pain at rest due to reduced blood flow from partial occlusion, unlike stable angina, reflecting demand-supply mismatch without full blockage.

Choice B reason: Complete occlusion causes ST-elevation MI (STEMI), not NSTEMI, which involves partial blockage, leading to subendocardial ischemia without full transmural infarction.

Choice C reason: Chest pain on exertion resolving with rest describes stable angina, not NSTEMI, which occurs unpredictably, often at rest, due to unstable plaque rupture.

Choice D reason: NSTEMI results from partial coronary occlusion, causing ischemia without ST elevation, detectable by troponin rise, distinguishing it from STEMI’s complete blockage.

A. Teach the client how to prevent orthostatic hypotension B. Explain the importance of taking the medication with food to increase absorption C. Instruct the client to take a cough suppressant if a cough develops D. Encourage the client to eat foods high in potassium

Correct Answer is A

Explanation

Choice A reason: Captopril, an ACE inhibitor, lowers blood pressure, risking orthostatic hypotension; teaching posture changes (slow standing) prevents falls, a key safety instruction.

Choice B reason: Captopril is taken on an empty stomach for optimal absorption, as food reduces bioavailability, so this statement contradicts proper administration guidelines.

Choice C reason: Cough, an ACE inhibitor side effect, doesn’t warrant suppressants; it may require switching drugs, not masking, making this instruction inappropriate.

Choice D reason: Captopril can raise potassium by reducing aldosterone; high-potassium foods risk hyperkalemia, so this advice is unsafe without monitoring levels.
