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: Hypnotics, like Ambien, induce sleep, matching Seconal’s primary action. This aligns with nursing pharmacology standards for sleep-producing drugs. It’s universally recognized, distinctly applied to facilitate rest effectively in practice.
Choice B reason: Anticoagulants prevent clotting, not induce sleep like hypnotics do. This misidentifies Seconal’s purpose, per nursing standards. It’s a universal error, distinctly unrelated to sleep production in pharmacology.
Choice C reason: Sedatives calm but don’t always induce sleep; hypnotics specifically do. This lacks precision, per nursing pharmacology. It’s universally distinct, missing the sleep focus of Seconal and Ambien.
Choice D reason: Psychotropics affect mood broadly, not just sleep like hypnotics. This errors in specificity, per nursing standards. It’s universally distinct, misaligning with the sleep-inducing role of these drugs.
Correct Answer is C
Explanation
Choice A reason: Temperature isn’t critical for morphine; respiratory depression is priority. This errors per nursing pharmacology standards. It’s universally distinct, less urgent than breathing.
Choice B reason: BP is relevant, but morphine’s main risk is respiratory. Rate trumps it per nursing standards. This is universally distinct, secondary to respiration.
Choice C reason: Morphine depresses breathing; respiratory rate is critical pre-administration. This aligns with nursing pharmacology standards. It’s universally distinct, ensuring safety first.
Choice D reason: Heart rate matters less than respiratory risk with morphine. This choice misaligns with nursing priorities. It’s universally distinct, not the top concern.
