A nurse is performing a focused assessment for vision on a client suspected of having vision loss. Which cranial nerve is the nurse assessing when determining if there are visual field or visual acuity deficits?

Choice A reason: This is incorrect because acute hemorrhagic stroke is not consistent with these observations. Acute hemorrhagic stroke is a sudden bleeding in the brain that can cause severe neurological deficits, such as paralysis, aphasia, or coma. It does not cause tremors, slowness, or mask-like facial expressions.

Choice B reason: This is incorrect because Alzheimer's disease is not consistent with these observations. Alzheimer's disease is a progressive degeneration of the brain that causes cognitive impairment, memory loss, and behavioral changes. It does not cause tremors, slowness, or mask-like facial expressions.

Choice C reason: This is the correct answer because Parkinson's disease is consistent with these observations. Parkinson's disease is a chronic disorder of the brain that affects movement and coordination. It causes tremors, slowness, rigidity, and postural instability, as well as mask-like facial expressions due to reduced facial muscle activity.

Choice D reason: This is incorrect because traumatic brain injury is not consistent with these observations. Traumatic brain injury is damage to the brain caused by external force, such as a blow, fall, or penetration. It can cause various neurological symptoms depending on the location and severity of the injury, but it does not typically cause tremors, slowness, or mask-like facial expressions.

Choice A Reason: This is a correct choice. Standing next to the client when speaking is an action that the nurse should plan to take, as it helps the client hear better and see the nurse's facial expressions and lip movements. The nurse should also speak clearly and slowly, use simple words and sentences, and avoid covering their mouth.

Choice B Reason: This is a correct choice. Guiding the client away from background noise is an action that the nurse should plan to take, as it reduces distractions and interference with hearing. The nurse should also choose a well-lit and quiet place for communication and turn off any unnecessary devices or appliances.

Choice C Reason: This is an incorrect choice. Providing a copy of the instructions printed in Braille is not an action that the nurse should plan to take, as it is not helpful for clients with hearing loss. Braille is a system of raised dots that represents letters and numbers for people who are blind or visually impaired. The nurse should provide a copy of the instructions printed in large font or use pictures or diagrams to supplement verbal information.

Choice D Reason: This is a correct choice. Repeating any phrases that the client misunderstands is an action that the nurse should plan to take, as it ensures comprehension and clarification of important information. The nurse should also ask open-ended questions, encourage feedback, and summarize key points at the end of the conversation.
