Which cranial nerve(CN) is most commonly affected by a tumor?

Correct Answer: D

Rationale: The correct answer is D: CN VIII. This cranial nerve, known as the vestibulocochlear nerve, is commonly affected by tumors due to its location near the cerebellopontine angle. Tumors in this area can compress CN VIII, leading to symptoms such as hearing loss, vertigo, and imbalance. CN II (A), CN IV (B), and CN V (C) are less commonly affected by tumors compared to CN VIII. CN II is the optic nerve, CN IV is the trochlear nerve, and CN V is the trigeminal nerve, each with different functions and locations in the brain. Therefore, D is the most likely cranial nerve to be affected by a tumor based on its anatomical proximity to common tumor sites.

Correct Answer: B

Rationale: The correct answer is B: Standard precautions. Standard precautions should be implemented when changing a dressing on a client's abdomen as it includes hand hygiene, gloves, and appropriate personal protective equipment based on the risk of exposure to blood or body fluids. This technique helps prevent the spread of infection and ensures the safety of both the nurse and the client. A: Contact precautions are used for clients with specific infections that can be transmitted by direct contact. C: Droplet precautions are for infections transmitted through respiratory droplets. D: Airborne precautions are for infections transmitted via small particles that remain in the air for a long time. In summary, Standard precautions are the most appropriate technique for changing a dressing on a client's abdomen as they provide a comprehensive approach to infection prevention.

Correct Answer: C

Rationale: Step-by-step rationale for why establishing trust and rapport (choice C) is the correct answer: 1. Establishing trust and rapport is vital in building a therapeutic relationship with the client. 2. Trust is the foundation for effective communication, understanding the client's needs, and ensuring cooperation. 3. By building trust first, the nurse can create a supportive environment for the client's care needs. 4. Setting priorities (choice A), assessing the home environment (choice B), and promoting learning (choice D) all rely on a foundation of trust and rapport. Summary: Establishing trust and rapport is the first crucial step to ensure successful home care visits. Setting priorities, assessing the home environment, and promoting learning can follow once a strong relationship is established.

Correct Answer: D

Rationale: The correct answer is D: Encourage the client to identify potential sources of emotional support. This is the most helpful action because it focuses on providing the client with practical support to cope with her chronic sorrow. By identifying potential sources of emotional support, the client can strengthen her support network and feel less isolated in dealing with her husband's terminal illness. Option A: Questioning the client about her knowledge of cancer treatment options is not the most appropriate action in this scenario as it does not directly address the client's emotional needs related to chronic sorrow. Option B: Questioning the client about her husband's prognosis may increase the client's distress and anxiety, which is not beneficial in supporting her emotional well-being. Option C: Determining the means used by the client to cope with loss in the past is important but may not be the most immediate and practical step in addressing the client's current emotional needs.

Correct Answer: A

Rationale: The correct answer is A: The use of deodorant. Deodorant contains metals that can interfere with the imaging process of a mammogram, leading to false results. Other choices (B, C, D) do not directly affect the mammogram imaging process. Makeup and medications may not interfere with the test, and eating breakfast should not impact the mammogram results.
