Which class of pulmonary medications suppresses coughing?
Expectorants
Mast cell stabilizers
Mucolytics
Antitussives
The Correct Answer is D
Choice A reason: Expectorants loosen mucus; antitussives suppress cough, not promote it. This reverses, per nursing pharmacology. It’s universally distinct, errors in cough management.
Choice B reason: Mast cell stabilizers prevent asthma; antitussives stop coughing directly. This misidentifies, per nursing standards. It’s universally distinct, unrelated to cough suppression.
Choice C reason: Mucolytics thin mucus; antitussives suppress cough, not thin secretions. This errors, per nursing pharmacology. It’s universally distinct, missing the suppression focus.
Choice D reason: Antitussives, like dextromethorphan, suppress coughing effectively in pulmonary care. This matches, per nursing standards. It’s universally applied, distinctly targeting cough relief.

Correct Answer is C
Explanation
Choice A reason: Sedatives induce calm, not lower blood pressure directly. Vasodilators target BP reduction specifically. This choice errors per nursing pharmacology standards. It’s universally distinct as unrelated to BP management, lacking the required mechanism.
Choice B reason: Intermediate-acting defines duration, not BP-lowering action. Vasodilators reduce pressure effectively. This choice misaligns with nursing pharmacology definitions. It’s universally distinct, missing the functional role specified in the question.
Choice C reason: Vasodilators, like nitroglycerin, widen vessels, lowering BP efficiently. This matches nursing pharmacology standards precisely. It’s universally recognized, distinctly applied in practice for hypertension or angina management effectively.
Choice D reason: Vasoconstrictors raise BP, opposite of lowering it. Vasodilators fit the description accurately. This choice errors per nursing pharmacology principles. It’s universally distinct, contradicting the question’s intent entirely.
Correct Answer is B
Explanation
Choice A reason: 30 cc overestimates; cups lose accuracy below 10 cc typically. Syringes are better for small doses. This errors per nursing standards. It’s universally distinct, impractical for precise small-volume measurement.
Choice B reason: 10 cc is the threshold; below this, cups are inaccurate. Syringes ensure precision, per nursing pharmacology. This aligns universally, distinctly standard for accurate liquid dosing.
Choice C reason: 20 cc exceeds the inaccuracy limit; 10 cc is correct. Cups falter below this level. This choice errors per nursing standards. It’s universally distinct, overestimating the threshold.
Choice D reason: 5 cc underestimates; inaccuracy starts at 10 cc for cups. Syringes are needed below this. This errors per nursing pharmacology. It’s universally distinct, missing the mark.
