Angiotensin inhibitors like Vasotec (enalapril):

Choice A reason: Paroxetine, an SSRI, needs weeks to ease OCD symptoms. This fits nursing pharmacology education standards. It’s universally distinct, critical for patient expectations.

Choice B reason: PRN isn’t for SSRIs; daily use treats OCD effectively. This errors per nursing standards. It’s universally distinct, misrepresenting administration schedule.

Choice C reason: Bedtime isn’t key; paroxetine isn’t for sleep primarily. This choice misaligns with nursing pharmacology. It’s universally distinct, off OCD focus.

Choice D reason: Weight gain is secondary; delayed effect is primary teaching. This errors per nursing standards. It’s universally distinct, missing main point.

Choice A reason: Bactericidal drugs, like penicillin, directly kill bacteria by disrupting cell walls or metabolism. This matches the question’s definition, ensuring effective infection control. It aligns with nursing pharmacology standards for classifying drugs that destroy bacteria, a critical distinction in treatment, universally recognized and distinctly applied in practice.

Choice B reason: Antineoplastic drugs target cancer cells, not bacteria, focusing on tumor growth inhibition. Destroying bacteria is bactericidal, not antineoplastic. This misidentifies the drug’s purpose, conflicting with nursing pharmacology principles. It’s irrelevant to bacterial destruction, a clear error in classification universally understood in healthcare.

Choice C reason: Analgesics relieve pain, lacking action against bacteria. Bactericidal drugs kill bacteria, not manage symptoms. This choice misaligns with the question’s focus on destruction, per nursing pharmacology standards. It fails to address infection, a distinct mismatch universally recognized in drug categorization.

Choice D reason: Bacteriostatic drugs inhibit bacterial growth, not destroy them outright. Bactericidal agents kill directly, per nursing terminology. This errors by suggesting stasis over destruction, contradicting the question’s intent. It’s a common distinction in pharmacology, universally applied for effective infection management.
