Final answer:
An annual eye exam is recommended for clients with hypertension to monitor for a condition called hypertensive retinopathy, which can cause vision problems or loss. Regular exams help identify signs of retinopathy early for proper management of hypertension.
Step-by-step explanation:
An annual eye exam is recommended for clients with hypertension because high blood pressure can lead to a condition called hypertensive retinopathy. This occurs when chronically elevated blood pressure damages the blood vessels in the retina, leading to vision problems or even vision loss. By obtaining regular eye exams, a nurse can help identify any signs of hypertensive retinopathy early on, allowing for timely intervention and management of the client's hypertension.
