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

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.

Choice A rationale

Respiratory rate of 24/min indicates possible respiratory distress but is not a common adverse effect of propranolol, which typically affects heart rate and blood pressure.

Choice B rationale

An oral temperature of 38.9° C (102°F) suggests fever, which is not a known adverse effect of propranolol. Common side effects are bradycardia, hypotension, and fatigue.

Choice C rationale

Blood pressure of 118/78 mm Hg is within normal range (90/60 to 120/80 mm Hg) and is not an adverse effect of propranolol, which usually lowers blood pressure.

Choice D rationale

Apical pulse of 50/min indicates bradycardia, a common adverse effect of propranolol, which reduces heart rate by blocking beta-adrenergic receptors.
