Which over-the-counter medication should be avoided by the client with prostatitis? A. Motrin (ibuprofen) B. Colace (docusate) C. Benedryl (diphenhydramine) D. Aleve (naproxen)

First, let's understand the effects of each medication: A. Motrin (ibuprofen) - This is a nonsteroidal anti-inflammatory drug (NSAID) that helps in reducing inflammation, swelling, and pain. B. Colace (docusate) - This medication is a stool softener, which helps in relieving constipation. C. Benedryl (diphenhydramine) - This is an antihistamine that helps in treating allergies and common cold symptoms. It also has some sedative effects. D. Aleve (naproxen) - This is another NSAID that helps in reducing inflammation, pain, and swelling.

Now, let's analyze the potential consequences of each medication on someone with prostatitis: A. Motrin (ibuprofen) - This medication could potentially help reduce inflammation and pain in the prostate. However, NSAIDs may affect kidney function, which is important for filtering waste products and regulating the balance of fluids in the body. B. Colace (docusate) - This medication would not directly affect prostatitis, as its primary function is treating constipation. It can, however, indirectly benefit the client with prostatitis by preventing constipation that could lead to increased pressure on the prostate. C. Benedryl (diphenhydramine) - Antihistamines like Benedryl are known to cause urinary retention, a condition when the bladder does not empty properly during urination. For someone with prostatitis, urinary retention can worsen the inflammation and symptoms. D. Aleve (naproxen) - Like Motrin, Aleve may help in reducing inflammation and pain associated with prostatitis. However, it also has the same risks related to kidney function.

Based on the analysis of each medication's effects on prostatitis, the most concerning medication is: C. Benedryl (diphenhydramine) - because it can cause urinary retention, which can worsen the inflammation and symptoms of prostatitis. Therefore, the correct answer is: C. Benedryl (diphenhydramine)
