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 D
Explanation
Choice A reason: Bed rest increases clot risk and deconditioning; vasodilators lower pressure, but mobility is beneficial unless contraindicated, making this overly restrictive.
Choice B reason: Assisting ambulation helps, but it’s less proactive; it doesn’t address orthostatic hypotension risks at initiation of movement, where falls are most likely.
Choice C reason: Monitoring intake/output tracks fluid status, not directly addressing vasodilation’s hypotensive effects during position changes, missing the primary safety concern.
Choice D reason: Rising slowly counters orthostatic hypotension from vasodilation; it allows autoregulation to stabilize pressure, reducing fall risk in an active elderly patient.
Correct Answer is C
Explanation
Choice A reason: Promising instant relief is misleading; most drugs take time, and false expectations may erode trust, reducing cooperation in a toddler’s care.
Choice B reason: Calling it candy is unethical; it risks future candy confusion with drugs, potentially leading to accidental ingestion, unsafe for a 3-year-old.
Choice C reason: Confident explanation suits a toddler’s understanding; it builds trust, reduces fear, and ensures cooperation by clearly stating purpose and process age-appropriately.
Choice D reason: Firm insistence may scare a toddler; without explanation, it lacks reassurance, potentially increasing resistance and distress during medication administration.
