A patient is diagnosed with benign prostatic hypertrophy. The nurse realizes that this patient's blood pressure should be closely measured to determine what?
1. whether the patient can tolerate doxazosin mesylate (Cardura)
2. whether surgery is indicated
3. the volume of urine being retained in the bladder
4. the dose of finasteride (Proscar)
Correct Answer: 1
Excessive smooth muscle contraction in benign prostatic hypertrophy (BPH) may be blocked with the alpha-adrenergic antagonists such as doxazosin mesylate (Cardura). This medication relieves obstruction and increases the flow of urine. It may cause orthostatic hypotension. The use of surgical intervention to manage BPH is not determined by monitoring blood pressure. The volume of urinary residual does not have bearing in this question. Finasteride (Proscar) does not impact blood pressure.
