The patient has Levaquin 500 mg ordered once daily. The Levaquin is available in 100 mL of NS and should infuse over 1 hour. Using tubing with a 60 gtt/mL drop factor, how many drops per minute should the Levaquin be infused?
60 gtts/min
100 gtts/min
120 gtts/min
200 gtts/min
The Correct Answer is B
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.

Correct Answer is B
Explanation
Choice A reason: Inhalation targets lungs; transdermal means skin absorption, not respiratory, and this route doesn’t match the prescribed method’s pharmacokinetic profile.
Choice B reason: Transdermal drugs absorb through skin layers; this delivers medication systemically via dermal capillaries, bypassing first-pass metabolism, as intended by the order.
Choice C reason: Rectal administration uses suppositories; transdermal is skin-based, not mucosal, and this route doesn’t align with the prescribed absorption method.
Choice D reason: Sublingual dissolves under the tongue; transdermal is cutaneous, not oral, and this differs entirely from the skin-based delivery system specified.
Correct Answer is C
Explanation
Choice A reason: While documentation and supervisor notification are crucial, immediate action involving the health care provider ensures timely response to potential adverse effects from the medication error.
Choice B reason: Relying solely on the absence of drug allergies is insufficient and may jeopardize patient safety. Errors require immediate communication and reporting for appropriate interventions.
Choice C reason: Timely provider notification prioritizes patient safety and enables corrective measures. Completing an incident report supports institutional transparency and learning to prevent future errors.
Choice D reason: Administering additional drugs risks compounding harm. The priority is addressing the initial error and ensuring patient safety without introducing further interventions.
