The physician orders Ceclor 175 mg po for an ear infection. After reconstitution, the medication is available as 125 mg/5 mL. How many milliliters will the nurse administer?
5 mL
7 mL
10 mL
14 mL
The Correct Answer is B
Choice A reason: 5 mL gives 125 mg; this underdoses the 175 mg order, reducing Ceclor’s antibacterial effect, risking persistent ear infection due to insufficient concentration.
Choice B reason: 7 mL is correct; 175 mg divided by 125 mg/5 mL equals 7 mL, delivering the exact cephalosporin dose for effective otitis media treatment.
Choice C reason: 10 mL provides 250 mg; this overdoses Ceclor, risking gastrointestinal upset or resistance, exceeding the therapeutic need for the infection safely.
Choice D reason: 14 mL yields 350 mg; this extreme overdose amplifies side effects like diarrhea or toxicity, far beyond the ordered 175 mg dose requirement.

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 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.
