A nurse is caring for a client who has a subarachnoid hemorrhage and asks why they are having a CT angiography. Which of the following should the nurse understand about CT angiography?

A. "I can't eat as much as I used to": While changes in eating habits may be related to various factors, such as appetite changes or difficulty chewing/swallowing, this statement does not specifically indicate how hearing loss affects the client's ability to perform ADLs.

B. "I get dizzy when I nod my head": This statement suggests that the client is experiencing dizziness, which could be related to hearing loss affecting their sense of balance. Dizziness can significantly impact the client's ability to perform activities of daily living (ADLs) safely, such as walking, cooking, or bathing, as it increases the risk of falls and injury.

C. "I wash my hair every other day": This statement describes a personal hygiene habit and does not directly indicate how hearing loss affects the client's ability to perform ADLs.

D. "I walk my dog at least twice a day": This statement describes an activity the client engages in and does not directly indicate how hearing loss affects the client's ability to perform ADLs. Walking a dog does not necessarily require hearing ability, as it primarily involves physical movement and visual observation.

A) "Vision changes occur when pressure in the eye is increased due to a decrease of aqueous humor." This statement describes a mechanism associated with glaucoma, not cataracts. In cataracts, vision changes occur due to the opacity or cloudiness of the lens, not changes in intraocular pressure.

B) "Vision changes occur when blood vessels leak fluid or blood under a portion of the retina." This statement describes a mechanism associated with retinal diseases like diabetic retinopathy, not cataracts. In cataracts, the lens becomes cloudy, affecting the passage of light through the eye.

C) "Vision changes occur when the cloudy lens alters the passage of light through the eye." This statement is correct. Cataracts cause the lens of the eye to become cloudy, which interferes with the passage of light through the eye. This results in vision changes such as blurred vision, glare, and difficulty seeing in low light conditions.

D) "Vision changes occur when retinal tissue pulls away from the blood vessels in the eye." This statement describes a mechanism associated with retinal detachment, not cataracts. In cataracts, the lens becomes opaque, but the retinal tissue remains intact.
