A nurse in an ophthalmology clinic is interviewing a client who was referred by his primary care provider for suspicion of cataracts. The nurse should expect the client to report:
Having a decreased ability to perceive colors.
Having a loss of peripheral vision.
Seeing bright flashes of light and floaters.
Loss of central vision.
The Correct Answer is A
Choice A rationale
Cataracts cause the lens of the eye to become cloudy, leading to a decreased ability to perceive colors. This is due to the scattering of light as it passes through the cloudy lens, which reduces the clarity and vibrancy of colors.
Choice B rationale
Loss of peripheral vision is more commonly associated with glaucoma, a condition where increased intraocular pressure damages the optic nerve.
Choice C rationale
Seeing bright flashes of light and floaters is typically a symptom of retinal detachment, a serious condition where the retina pulls away from its normal position.
Choice D rationale
Loss of central vision is often linked to macular degeneration, a condition that affects the central part of the retina responsible for sharp, detailed vision.

Correct Answer is C
Explanation
Choice A rationale
Applying cool compresses can help reduce swelling and discomfort, but it is not the primary instruction for a client scheduled for retinal detachment surgery.
Choice B rationale
Eye drops to constrict the pupils are not typically prescribed for retinal detachment surgery. The focus is on preventing further detachment and ensuring proper healing.
Choice C rationale
Restricting head movement is crucial to prevent further detachment of the retina and to promote proper healing after surgery. The client should be instructed to avoid sudden or excessive head movements.
Choice D rationale
Keeping both eyes patched is not necessary and may cause unnecessary discomfort and disorientation for the client.
Correct Answer is C
Explanation
Choice A rationale
White drainage on the eyelids is not a normal finding and should be reported to the surgeon. However, this is not a standard discharge instruction but rather a sign of potential infection.
Choice B rationale
Sleeping on the abdomen is not recommended after cataract surgery as it can increase pressure on the eye and disrupt healing. Patients are usually advised to sleep on their back or the unaffected side.
Choice C rationale
Avoiding lifting anything heavier than 4.5 kg (10 lb) for 1 week is a standard instruction to prevent increased intraocular pressure and ensure proper healing of the surgical site.
Choice D rationale
Bending at the waist to pick up objects can increase intraocular pressure and should be avoided. Patients are advised to bend at the knees instead.
