A nurse is caring for a client who has varicella-zoster virus.
Which of the following medications should the nurse expect to administer?

Choice A rationale

Trough levels should be drawn just before the next dose, not 60 minutes after infusion, to ensure accurate assessment of the lowest concentration of vancomycin in the patient's bloodstream.

Choice B rationale

There is no need to change the infusion site after each dose unless there are signs of phlebitis or infiltration. Consistent monitoring of the site for adverse reactions is sufficient.

Choice C rationale

Contacting the provider for prescription clarification is necessary if the infusion duration seems too rapid. Vancomycin should be infused over at least 60 minutes to reduce the risk of red man syndrome.

Choice D rationale

Peak levels should be drawn 1-2 hours after infusion completion, not before. Monitoring peak levels helps in assessing the maximum concentration of vancomycin in the patient's system.

Choice A rationale

Terazosin is an alpha-1 adrenergic blocker used primarily to treat hypertension by relaxing blood vessels and improving blood flow.

Choice B rationale

Terazosin is not indicated for heart failure treatment as it does not have direct effects on improving cardiac function or reducing fluid overload.

Choice C rationale

Male pattern baldness is typically treated with medications like minoxidil or finasteride, not terazosin, which targets alpha-1 receptors.

Choice D rationale

Benign prostatic hypertrophy is also treated with terazosin as it relaxes the smooth muscle in the prostate and bladder neck, improving urine flow.

Choice E rationale

Erectile dysfunction is managed with medications like sildenafil or tadalafil, which work by enhancing blood flow, not through alpha-1 adrenergic blockade.
