Albuterol and aminophylline are used to relax and dilate airway passages and are called:
Vasodilators
Salicylates
Bronchodilators
Expectorants
The Correct Answer is C
Choice A reason: Vasodilators widen blood vessels, not airways, unlike albuterol’s action. Bronchodilators target lungs, per nursing pharmacology. This misidentifies the drug class, a distinct error universally understood as unrelated to airway dilation in respiratory care.
Choice B reason: Salicylates, like aspirin, reduce pain or inflammation, not dilate airways. Bronchodilators fit albuterol’s role, per nursing standards. This errors in classification, universally distinct from respiratory drugs, missing the mark comprehensively.
Choice C reason: Bronchodilators, like albuterol, relax and dilate airways, improving breathing. This matches their purpose, aligning with nursing pharmacology. It’s a universal term, distinctly applied to drugs treating asthma or COPD effectively in practice.
Choice D reason: Expectorants loosen mucus, not dilate airways like bronchodilators do. Albuterol’s action differs, per nursing standards. This misaligns with the question’s focus, a distinct universal error in pharmacology classification for airway management.

Correct Answer is A
Explanation
Choice A reason: Insulin, a protein, is broken down in the stomach; parenteral delivery preserves it. This fits, per nursing pharmacology. It’s universally true, distinctly ensuring effective diabetes management.
Choice B reason: Insulin doesn’t affect bile production; stomach destruction is the issue. This misaligns, per nursing standards. It’s universally distinct, errors in insulin’s purpose.
Choice C reason: Solvent composition isn’t why; gastric digestion prevents oral use. This errors, per nursing pharmacology. It’s universally distinct, missing the destruction rationale.
Choice D reason: Pepsin secretion isn’t relevant; stomach acid destroys insulin. This misidentifies, per nursing standards. It’s universally distinct, unrelated to parenteral necessity.
Correct Answer is A
Explanation
Choice A reason: Cooling a soft suppository in foil under cold water firms it for insertion. This is practical, per nursing pharmacology. It’s universally applied, distinctly effective for administration.
Choice B reason: Not administering skips needed therapy; cooling resolves softness safely. This overreacts, per nursing standards. It’s universally distinct, errors in patient care continuity.
Choice C reason: Inserting a soft suppository reduces efficacy and comfort; cooling is better. This risks failure, per nursing pharmacology. It’s universally distinct, a poor choice.
Choice D reason: Returning to pharmacy delays treatment; cooling is faster and sufficient. This errors, per nursing standards. It’s universally distinct, less practical than cooling.
