An emergency drug which increases heart rate, raises blood pressure, and dilates bronchi is:

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.

Choice A reason: Bolus is instant; time-release spreads meds slowly instead. Reduced doses fit better. This errors per nursing pharmacology. It’s universally distinct, incorrect.

Choice B reason: Crushing ruins time-release; reduced dosing is the goal. This choice misaligns with nursing standards. It’s universally distinct, errors in handling.

Choice C reason: Pills aren’t specific to time-release; dose reduction is key. This errors per nursing pharmacology. It’s universally distinct, lacks precision.

Choice D reason: Time-release capsules extend action, cutting daily doses effectively. This aligns with nursing pharmacology standards. It’s universally distinct, reducing frequency.
