Rationale: The correct answer is B: Vitamin K. Warfarin inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.

Rationale: Hepatic encephalopathy is caused by the buildup of ammonia in the body, not urea. Ammonia accumulates due to liver dysfunction, leading to neurological symptoms. Fatty infiltration of the liver may lead to conditions like non-alcoholic fatty liver disease, but it is not the direct cause of hepatic encephalopathy. Jaundice is a symptom of liver dysfunction but is not the primary cause of hepatic encephalopathy.

Rationale: When a nurse has established a close relationship with a dying client's family, it is important to offer holistic support. Encouraging family discussion of feelings allows them to express and process their emotions, accepting the family's experience of anger validates their feelings, and facilitating the use of spiritual practices identified by the family can provide comfort and solace. Therefore, all of the above interventions are crucial in dealing with the family during such a challenging time. Choices A, B, and C work together to provide comprehensive emotional and spiritual support, making option D the correct answer.

Correct Answer: B

Rationale: The correct answer is B: "Have you had any unexplained weight loss?" Unexplained weight loss can be a common symptom of various endocrine disorders, such as hyperthyroidism and diabetes. This weight loss is often despite an adequate or increased appetite. Choices A, C, and D are less likely to be directly associated with endocrine dysfunction. Pain in the legs when walking could be related to musculoskeletal issues, changes in bowel movements may suggest gastrointestinal concerns, and joint pain is more commonly linked to rheumatologic conditions rather than primary endocrine disorders.
