Anti-psychotics (major tranquilizers) are used for:

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: Rectal is enteral, using the GI tract for absorption. Vaginal isn’t enteral. This fits nursing pharmacology standards. It’s universally distinct, part of digestive routes.

Choice B reason: Nasogastric delivers to stomach, an enteral method clearly. Vaginal differs entirely. This aligns with nursing standards. It’s universally distinct, a GI route.

Choice C reason: Vaginal is topical/mucosal, not enteral like GI routes. This is the exception per nursing pharmacology. It’s universally distinct, outside digestive administration methods.

Choice D reason: Oral is enteral, absorbed via digestive system typically. Vaginal isn’t included. This matches nursing standards. It’s universally distinct, a core enteral route.
