Sample itemWhat is the main effect of a short-acting beta-2 agonist inhaler?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. Bronchodilation
The central Respiratory drugs concept identifies Bronchodilation as the best answer because it directly explains the mechanism, indication, adverse effect, or organism feature described.
Option by option
A. Reduced surfactant
Reduced surfactant is unsupported by the mechanism or clinical clue in the stem.
B. Bronchodilation (correct)
Correct. Bronchodilation matches the decisive point in this scenario.
C. Increased mucus viscosity
Increased mucus viscosity does not fit the stated respiratory drugs relationship.
D. Vasoconstriction only
Vasoconstriction only has another context but is not the most appropriate answer here.
