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?

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.
