Angiotensin inhibitors like Vasotec (enalapril):

Choice A reason: Decreasing BP is correct; other options don’t apply. This choice errors per nursing pharmacology. It’s universally distinct, denies the right answer.

Choice B reason: Vasotec, an ACE inhibitor, lowers BP by vessel relaxation. This aligns with nursing pharmacology standards. It’s universally applied, distinctly effective.

Choice C reason: Elevating BP opposes ACE inhibitor action entirely. Lowering is correct. This errors per nursing standards. It’s universally distinct, reverses function.

Choice D reason: No effect contradicts Vasotec’s BP-lowering purpose. This choice misaligns with nursing pharmacology. It’s universally distinct, errors in drug role.

Choice A reason: Antihistamines block histamine, not raise HR or BP. Epinephrine fits emergency needs. This errors per nursing pharmacology. It’s universally distinct, lacking stimulatory emergency effects.

Choice B reason: Sedatives reduce activity, not increase HR or BP. Epinephrine acts oppositely. This choice reverses nursing standards. It’s universally distinct, unsuitable for emergency stimulation.

Choice C reason: Epinephrine boosts HR, BP, and dilates bronchi in emergencies. This matches nursing pharmacology standards. It’s universally applied, distinctly effective for acute life-saving interventions.

Choice D reason: Hormones vary; epinephrine specifically meets all criteria emergently. This lacks precision per nursing standards. It’s universally distinct, too vague for the question’s intent.
