A nurse is reinforcing teaching about the side effects of metoprolol. Which of the following client statements indicates an understanding of the teaching?

Choice A reason: Remeasuring confirms the 190/110 mm Hg reading, ensuring accuracy in kidney failure, where hypertension is common. It’s the first step before acting.

Choice B reason: Administering medication without verification risks error; BP may be inaccurate. In kidney failure, precise BP guides therapy, so this waits.

Choice C reason: Reporting to the charge nurse follows confirmation; unverified readings waste time. Accuracy in chronic kidney failure is critical before escalating.

Choice D reason: Bed rest may help, but confirming BP first prioritizes data. Kidney failure needs validated hypertension readings to direct immediate care safely.

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.
