A nurse is administering a dose of insulin to a patient. To practice nursing safely and effectively, the nurse should:
Give the drug before a meal.
Confirm with the patient the site of the last injection.
Inject the insulin in the deltoid muscle.
Have another licensed nurse double-check the dose.
The Correct Answer is D
Choice A reason: Administering insulin at proper timing correlates with mealtimes. However, this alone doesn't ensure safe practice.
Choice B reason: Confirming the injection site prevents lipodystrophy but does not address dose accuracy, which is vital for safety.
Choice C reason: Insulin is injected subcutaneously, not in the deltoid muscle. Using incorrect sites disrupts absorption.
Choice D reason: Double-checking insulin dose prevents administration errors, ensuring compliance with medication safety protocols.

Correct Answer is B
Explanation
Choice A reason: Lungs excrete volatile drugs like anesthetics; most medications aren’t metabolized here, as they lack the cytochrome enzymes needed for broad drug breakdown.
Choice B reason: The liver is the primary site; cytochrome P450 enzymes metabolize most drugs, converting them into active or excretable forms, critical for pharmacokinetics.
Choice C reason: Kidneys excrete metabolites; they filter, not metabolize, most drugs, relying on prior liver processing, making them secondary in the metabolic pathway.
Choice D reason: The colon absorbs some drugs but doesn’t metabolize most; its role is minimal compared to the liver’s extensive enzymatic drug transformation capacity.
Correct Answer is B
Explanation
Choice A reason: 60 gtts/min assumes 100 mL in 100 minutes; this underestimates the 1-hour order, delivering Levaquin too slowly, risking subtherapeutic antibiotic levels.
Choice B reason: 100 gtts/min is correct; 100 mL over 1 hour (60 min) with 60 gtts/mL equals 6000 gtts total, divided by 60 minutes matches the ordered rate.
Choice C reason: 120 gtts/min overestimates; it implies 100 mL in 50 minutes, infusing too fast, potentially causing Levaquin-related side effects like tachycardia or irritation.
Choice D reason: 200 gtts/min is excessive; 100 mL in 30 minutes doubles the rate, risking toxicity or infusion reactions, far exceeding the 1-hour prescription safely.
