Tricyclics are classified as:

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.

Choice A reason: Specific droppers ensure dosing accuracy; other options fail this standard. Supplied droppers are calibrated, per nursing safety protocols. This choice dismisses precision, but it’s incorrect as “supplied dropper” is right, a distinct universal rule in medication administration.

Choice B reason: The supplied dropper is calibrated for the medication, ensuring accurate dosing every time. This prevents errors, aligning with nursing pharmacology standards. It’s a universal practice, distinctly critical for patient safety and effective drug delivery in all settings.

Choice C reason: Plastic droppers aren’t inherently accurate; calibration matters more. Supplied droppers ensure precision, per nursing standards. This focuses on material over function, a distinct error universally recognized as insufficient for safe medication administration.

Choice D reason: Any dropper risks incorrect dosing, compromising safety and efficacy. Supplied droppers match the drug, per nursing pharmacology. This choice ignores calibration, a universal error distinctly contradicting standards for precise medication delivery.
