A nurse in an ophthalmology clinic is interviewing a client who was referred by his primary care provider for suspicion of cataracts. Which of the following findings is consistent with manifestations of cataracts?
Loss of peripheral vision
A decreased ability to perceive colors
Loss of central vision
Seeing bright flashes of light and floaters
The Correct Answer is B
Choice A reason: This is incorrect because loss of peripheral vision is not a manifestation of cataracts, but of glaucoma. Glaucoma is a condition that causes increased pressure inside the eye and damage to the optic nerve, which can lead to loss of vision in the outer edges of the visual field. The nurse should assess the client's intraocular pressure and visual field test results to rule out glaucoma.
Choice B reason: This is correct because a decreased ability to perceive colors is a manifestation of cataracts. Cataracts are a condition that causes clouding or opacity of the lens, which is the transparent structure behind the pupil that focuses light onto the retina. Cataracts can reduce the clarity and contrast of vision and make colors appear faded or yellowish. The nurse should ask the client about any changes in color perception or brightness of objects.
Choice C reason: This is incorrect because loss of central vision is not a manifestation of cataracts but of macular degeneration. Macular degeneration is a condition that affects the macula, which is the central part of the retina that is responsible for sharp and detailed vision. Macular degeneration can cause blurred or distorted central vision, difficulty reading or recognizing faces, or dark spots in the visual field. The nurse should assess the client's visual acuity and fundoscopic examination results to rule out macular degeneration.
Choice D reason: This is incorrect because seeing bright flashes of light and floaters is not a manifestation of cataracts but of retinal detachment. Retinal detachment is a condition that occurs when the retina, which is the layer of tissue at the back of the eye that converts light into nerve impulses, separates from its underlying support tissue. Retinal detachment can cause sudden flashes of light, floaters, or shadows in the visual field. The nurse should refer the client to an ophthalmologist immediately if retinal detachment is suspected.

Correct Answer is B
Explanation
Choice A Reason: This choice is incorrect. Cranial Nerve VIII is the vestibulocochlear nerve, which is responsible for hearing and balance. It does not affect vision or eye movements.
Choice B Reason: This is the correct choice. Cranial Nerve II is the optic nerve, which is responsible for transmitting visual information from the retina to the brain. It affects visual field and visual acuity, which are measures of peripheral and central vision, respectively.
Choice C Reason: This choice is incorrect. Cranial Nerve I is the olfactory nerve, which is responsible for smell. It does not affect vision or eye movements.
Choice D Reason: This choice is incorrect. Cranial Nerve VII is the facial nerve, which is responsible for facial expressions and taste. It does not affect vision or eye movements.
Correct Answer is D
Explanation
Choice A Reason: This is incorrect because dimming the lights in the client's room is not a helpful action for providing discharge teaching for a client who has hearing loss. Dimming the lights can reduce the visibility and clarity of the nurse's facial expressions, gestures, and lip movements, which can aid in communication.
Choice B Reason: This is incorrect because increasing the rate of speech when talking with the client is not an effective action for providing discharge teaching for a client who has hearing loss. Increasing the rate of speech can make it harder for the client to follow and understand what the nurse is saying.
Choice C Reason: This is incorrect because answering client's questions using medical terminology is not an appropriate action for providing discharge teaching for a client who has hearing loss. Medical terminology can be confusing and unfamiliar to the client, which can impair comprehension and learning.
Choice D Reason: This is the correct choice because facing the client while talking is an important action for providing discharge teaching for a client who has hearing loss. Facing the client can enhance eye contact, attention, and rapport. It can also allow the client to see the nurse's facial expressions, gestures, and lip movements, which can facilitate communication.
