A nurse is caring for a client who has recurrent lower urinary tract infections (UTIs). Which of the following medications should the nurse expect to administer?
Ganciclovir
Amphotericin B
Azithromycin
Nitrofurantoin
The Correct Answer is D
Rationale:
A. Ganciclovir: Ganciclovir is an antiviral medication used primarily to treat viral infections such as cytomegalovirus (CMV), not bacterial infections like UTIs.
B. Amphotericin B: Amphotericin B is an antifungal agent used to treat serious fungal infections, not bacterial UTIs.
C. Azithromycin: Azithromycin is an antibiotic that is effective against a broad range of bacterial infections but is not commonly used for treating recurrent UTIs.
D. Nitrofurantoin: Nitrofurantoin is an antibiotic commonly used to prevent and treat recurrent lower urinary tract infections due to its efficacy in targeting the bacteria that typically cause UTIs.

Correct Answer is B
Explanation
Rationale:
A. Hydrochlorothiazide does not prevent angiotensin II from binding with receptor sites; this action is typically associated with ACE inhibitors or angiotensin receptor blockers.
B. Hydrochlorothiazide decreases the reabsorption of sodium and water in the distal renal tubule, which leads to increased urine output and decreased blood volume, effectively lowering blood pressure.
C. Hydrochlorothiazide does not block beta receptors; this is the mechanism of action for beta-blockers.
D. Hydrochlorothiazide does not promote the movement of extravascular fluids into the vascular compartment; instead, it reduces blood volume by promoting diuresis.
Correct Answer is ["A","D"]
Explanation
Rationale:
A. Terazosin is indicated for the treatment of hypertension as it works by relaxing blood vessels, leading to lower blood pressure.
B. Terazosin is not indicated for heart failure; other medications are typically used to manage this condition.
C. Male pattern baldness is treated with other medications, such as finasteride, rather than terazosin.
D. Terazosin is also indicated for benign prostatic hypertrophy (BPH), as it helps alleviate urinary symptoms associated with this condition by relaxing the smooth muscles in the prostate and bladder neck.
E. Terazosin is not indicated for erectile dysfunction; it is primarily used for hypertension and BPH.
