A client has been admitted to the hospital with acute glomerulonephritis. The nurse plans to collect data and initially asks the client about a recent history of:

a) Headache: While headaches can occur with eye strain or other eye conditions, they are not a hallmark symptom of open-angle glaucoma.
b) Loss of peripheral vision: Open-angle glaucoma is characterized by gradual loss of peripheral vision, often referred to as "tunnel vision," due to increased intraocular pressure affecting the optic nerve.
c) Discomfort in the eyes: Open-angle glaucoma typically has no early symptoms, and discomfort is not usually a prominent feature unless the disease progresses.
d) Halos around lights: Halos around lights are more commonly associated with acute angle-closure glaucoma, where there is a sudden rise in intraocular pressure, not open-angle glaucoma.

a) Move his or her finger slowly toward the patient's nose: This is an appropriate action for testing accommodation, as it assesses the ability of the eyes to converge and maintain focus on the object as it moves closer.
b) Checking for a nystagmus: This is not directly related to accommodation, though nystagmus can be observed in other assessments for visual and neurological conditions.
c) Assess for convergence: Convergence is part of the accommodation process. It involves the eyes turning inward to focus on a near object.
d) Observe for pupillary constriction: Pupillary constriction is a key part of the accommodation response when focusing on a near object.
e) Note blinking: This is not necessary for assessing accommodation. Blinking can occur for various reasons but is not a direct sign of accommodation.
f) Hold his or her finger approximately 20 inches in front of the patient's eyes: For accommodation testing, the object should be moved closer, typically within 6-8 inches from the eyes.
