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 C

Explanation

Choice A reason: Informing the patient is secondary; it addresses communication but not immediate safety risks like needlestick injury, which is a higher priority post-injection per occupational health standards.

Choice B reason: Assessing comfort is important but not urgent; pain evaluation can wait after securing the needle, as safety from sharps exposure outweighs immediate patient feedback in priority.

Choice C reason: Engaging the safety sheath prevents needlestick injuries; it’s the priority action to protect the nurse and others from bloodborne pathogens, aligning with universal precautions post-injection.

Choice D reason: Checking for bleeding is routine but not critical; minor oozing is common and manageable later, while needle safety is an immediate concern to prevent infection risks.

A. One time. B. Two times. C. Three times. D. Five times.

Correct Answer is C

Explanation

Choice A reason: Checking medications only once increases the likelihood of errors. Safe practice requires multiple verification steps.

Choice B reason: While better than a single check, verifying only twice may still miss potential discrepancies in drug or dosage accuracy.

Choice C reason: The three-check system (when retrieving, preparing, and administering medication) minimizes errors, ensuring patient safety through consistent validation at each step.

Choice D reason: Excessive verification may delay administration, reducing practicality without significantly improving safety beyond three checks.
