Which of the following drugs is administered subcutaneously, in the belly, at least 2 inches from the umbilicus?

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: Antiparkinson drugs, like levodopa, restore dopamine and balance acetylcholine, vital for nerve signaling in Parkinson’s disease. This corrects motor deficits, aligning with nursing pharmacology. These neurotransmitters are universally targeted, distinctly addressing the disease’s chemical imbalance for effective impulse transmission.

Choice B reason: Epinephrine isn’t a primary Parkinson’s target; dopamine and acetylcholine are key. This misidentifies neurotransmitters involved in motor control, per nursing standards. Epinephrine relates to stress, not nerve restoration, making it a distinct error universally in pharmacology.

Choice C reason: Calcium supports nerve function but isn’t restored by antiparkinson drugs. Acetylcholine and dopamine are specific targets, per nursing knowledge. This choice errors by including calcium, missing the disease’s focus, a universal misunderstanding in pharmacology application distinctly.

Choice D reason: Epinephrine doesn’t treat Parkinson’s; dopamine and acetylcholine do. This pairing misaligns with antiparkinson goals, per nursing pharmacology. It overlooks dopamine’s role in motor control, a distinct error universally recognized in managing nerve impulse transmission effectively.
