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: Pharmacy technicians are not authorized to administer medications. Their scope involves preparation and dispensing under supervision, ensuring safety and compliance.
Choice B reason: Safe practice standards dictate that the preparing nurse administers the medications to ensure accuracy and accountability, minimizing potential errors.
Choice C reason: Delegating to the head nurse violates medication administration protocols, as accountability rests with the nurse who prepared the medications.
Choice D reason: Allowing other licensed nurses to distribute medications increases the risk of errors due to lack of firsthand knowledge of preparation specifics.
Correct Answer is D
Explanation
Choice A reason: Positioning the tablet next to the cheek alters absorption and delays onset. Sublingual placement ensures rapid effect.
Choice B reason: Swallowing bypasses sublingual absorption, reducing efficacy. The route is critical for desired therapeutic outcomes.
Choice C reason: Crushing and dissolving disrupts integrity, compromising rapid sublingual absorption. Proper administration maintains efficacy.
Choice D reason: Sublingual placement allows rapid dissolution and absorption via mucous membranes, ensuring swift therapeutic action.
