Final answer:
Dimenhydrinate, an antihistamine used for motion sickness, can worsen glaucoma by increasing intraocular pressure, and its use should be reported to a healthcare provider if a patient with glaucoma is prescribed this medication.
Step-by-step explanation:
If a client prescribed dimenhydrinate for motion sickness has a history of glaucoma, the nurse should report to the provider. Dimenhydrinate, an antihistamine, is commonly used to treat motion sickness and is known to be a safer alternative compared to the more potent autonomic drug scopolamine. However, dimenhydrinate can increase intraocular pressure, which is detrimental for individuals with glaucoma. Therefore, it is crucial for healthcare providers to carefully consider this medication's use in patients with existing eye conditions like glaucoma.
