A nurse is transcribing a client’s prescription for erythromycin 500 mg four times per day. Which of the following information should the nurse clarify with the provider?
Medication
Dosage
Route
Time
The Correct Answer is C
Choice A reason: Erythromycin is specified, so the medication is clear. No ambiguity exists here for clarification. Scientifically, drug identity is explicit, and errors arise elsewhere, making this unnecessary to question unless a different antibiotic was intended, which isn’t suggested.
Choice B reason: Dosage (500 mg) is precise, with no range or units needing clarification. Scientifically, this is a standard erythromycin dose, aligning with therapeutic norms for infections, leaving little room for error unless misheard, which isn’t indicated.
Choice C reason: Route (e.g., oral, IV) isn’t stated, critical for erythromycin, as administration affects bioavailability and efficacy. Scientifically, unclear delivery risks under- or overdosing, necessitating provider clarification to ensure safe, effective treatment per pharmacological standards.
Choice D reason: Time (four times daily) is clear, aligning with erythromycin’s pharmacokinetics for steady levels. Scientifically, frequency is unambiguous, requiring no clarification unless intervals were vague, which they aren’t, making this less urgent than route.

Correct Answer is C
Explanation
Choice A reason: Tetracycline allergy doesn’t cross-react with azithromycin, a macrolide. They’re distinct classes, so this isn’t a concern for chlamydia treatment safety.
Choice B reason: Sulfonamide allergy is unrelated to azithromycin’s macrolide structure. No cross-sensitivity exists, making this irrelevant for reporting in this case.
Choice C reason: Azithromycin is a macrolide; allergy to this class risks anaphylaxis. Reporting ensures safe alternative prescribing for chlamydia, a critical safety step.
Choice D reason: Penicillin allergy doesn’t affect azithromycin use; they’re unrelated structurally. This doesn’t require reporting, as no cross-reaction occurs here.
Correct Answer is A
Explanation
Choice A reason: Hearing loss is a known gentamicin ototoxicity effect, damaging cochlear hair cells irreversibly. Scientifically, this aminoglycoside targets the inner ear, causing tinnitus or deafness, a critical adverse reaction to monitor in pyelonephritis treatment per pharmacology evidence.
Choice B reason: Slurred speech suggests neurological issues (e.g., stroke), not gentamicin effects. Scientifically, this drug affects kidneys and ears, not speech centers, making this unrelated to its toxicity profile, which focuses on auditory and renal damage.
Choice C reason: Constipation isn’t linked to gentamicin; it’s more typical of opioids or immobility. Scientifically, this antibiotic’s side effects center on nephrotoxicity and ototoxicity, not gastrointestinal motility, rendering this an unlikely adverse reaction in this context.
Choice D reason: Hypotension may occur with rapid IV gentamicin, but it’s less common than ototoxicity. Scientifically, hearing loss is a hallmark toxicity, outweighing transient blood pressure drops, which are manageable and less specific to this drug’s adverse profile.
