A nurse is caring for a client who has a history of hypertension. Which of the following findings should the nurse recognize is indicative of transient ischemic attacks?

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.

Choice A reason: Advance directives outline future care wishes, unlike consent for immediate treatment. This conflates distinct legal documents, misinforming the client.

Choice B reason: Advance directives ensure autonomy, letting clients dictate care preferences pre-surgery. This accurately conveys their purpose in healthcare decision-making.

Choice C reason: Lawyer approval isn’t required; forms are legally valid with witnesses. This overstates complexity, deterring clients from creating directives.

Choice D reason: Directives apply to all, not just life-threatening cases. They’re proactive for any surgery, so this limits their broad applicability.
