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

Answer and Explanation

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: Crushing pills can alter drug efficacy and safety, especially for medications with controlled-release properties, making this inappropriate without specific provider instructions.

Choice B reason: Requesting a liquid form accommodates the patient’s physical limitations, maintaining therapeutic integrity and ensuring safe and effective medication administration.

Choice C reason: Introducing pills directly into the patient’s mouth risks aspiration and violates safe administration practices, emphasizing the need for alternative methods.

Choice D reason: If the patient struggles to hold the cup, self-administration becomes impractical. Assistance through appropriate alternative forms ensures compliance and safety.

A. Medication dependence B. Medication abuse C. Medication misuse D. Medication underuse

Correct Answer is C

Explanation

Choice A reason: Dependence is physiological reliance; crushing for speed isn’t dependence but alters delivery, not fitting the chronic need-based pattern of dependency.

Choice B reason: Abuse seeks euphoria or excess; crushing for relief manipulates timing, not intent, distinguishing it from recreational or harmful overuse patterns.

Choice C reason: Misuse is incorrect use; crushing extended-release voids its design, delivering a bolus dose unsafely, matching the patient’s action precisely.

Choice D reason: Underuse is insufficient dosing; crushing increases immediate effect, not reducing intake, making this the opposite of the patient’s medication alteration.
