Final answer:
The nurse should report benign prostatic hyperplasia to the healthcare provider when a client has a new prescription for dimenhydrinate to prevent potential exacerbation of urinary retention.
Step-by-step explanation:
The nurse should report benign prostatic hyperplasia to the provider before administering the medication dimenhydrinate given to treat motion sickness. Dimenhydrinate is an antihistamine that can be prescribed for motion sickness and works on the vestibular system to prevent nausea, vomiting, and dizziness. However, it also has anticholinergic effects, which can cause urinary retention. Since benign prostatic hyperplasia can also contribute to urinary retention, combining it with an antihistamine like dimenhydrinate could exacerbate the condition.
