Final answer:
A nurse should expect Finasteride or Prazosin as prescriptions for benign prostatic hyperplasia (BPH). The drug in the reference likely means a diuretic, which increases the frequency of urination by inhibiting the reabsorption of Na+ and Cl in the loop of Henle.
Step-by-step explanation:
For a client who has a new diagnosis of benign prostatic hyperplasia (BPH), the nurse should expect prescriptions that aim to relieve the symptoms associated with the enlarged prostate.
While Bethanechol and Prednisone are not typically used to treat this condition, Finasteride and Prazosin are common medications prescribed for BPH. Finasteride works by reducing the size of the prostate gland over time, while Prazosin is used to relax the muscles in the prostate to ease the symptoms such as difficulty urinating.
Regarding the question about a drug with a side effect that increases the frequency of urination, an oliguric medication working on the loop of Henle might inhibit the reabsorption of Na+ and Cl, resulting in diuresis. However, the term 'oliguric' is typically associated with reduced urine output, so it may be more accurate to refer to the medication as a diuretic, which is designed to increase urine production. Diuretics are commonly used to treat hypertension and can lead to increased frequency of urination as a side effect.
