Visual Problems Practice Test

In the case of a patient with hypertension presenting with sudden vision loss, administering the prescribed angiotensin-converting enzyme (ACE) inhibitor is the most appropriate action. Sudden vision loss, particularly in patients with hypertension, can be indicative of a serious condition such as hypertensive retinopathy or other vascular changes in the eye that could lead to permanent damage if not addressed promptly.

ACE inhibitors are vital in the management of hypertension as they help lower blood pressure by inhibiting the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. By controlling high blood pressure effectively, the nurse can help prevent further damage to the eye and potentially restore vision, if the underlying condition is manageable.

The other actions, while relevant in broader patient care, do not directly address the immediate risk associated with the patient's hypertension and vision loss. Monitoring vital signs and managing blood pressure takes precedence, ensuring the patient receives timely treatment to mitigate complications related to their acute condition.
