Correct Answer: B

Rationale: The best action for the nurse in this situation is to help the family show other ways to demonstrate love and caring. When a client with cancer is experiencing anorexia and mucositis, it can be challenging for them to eat even their favorite foods. By assisting the family in finding alternative ways to provide comfort and care, the nurse can help create a supportive environment for the client. Option A is not the best choice as explaining the pathophysiologic reasons may not address the emotional needs of the client and family. Option C, suggesting foods and liquids, might not be helpful if the client is unable to tolerate them due to their condition. Option D, telling the family that the client can't eat, may come across as dismissive and not supportive of the family's concerns.

Correct Answer: A

Rationale: In multiple myeloma, the nurse would expect to note an increased calcium level in the laboratory results. This elevation is due to bone destruction caused by the disease, releasing calcium into the bloodstream. Increased white blood cells (Choice B) are not typically associated with multiple myeloma. Additionally, a decreased blood urea nitrogen level (Choice C) is not a common finding in this disorder. Multiple myeloma is characterized by the proliferation of abnormal plasma cells in the bone marrow, leading to an increased number of plasma cells, not a decreased number (Choice D). Therefore, the correct answer is an increased calcium level.

Correct Answer: B

Rationale: The correct answer is B. A vesicovaginal fistula is an abnormal connection between the bladder and the vagina, leading to the passage of urine through the vagina. This condition can occur due to various reasons, including radiation therapy. Choice A, rupture of the bladder, is incorrect because a rupture would present with more severe symptoms and is not consistent with the client's description. Choice C, extreme stress, is incorrect as it does not explain the physical symptom of voiding through the vagina. Choice D, altered perineal sensation, is incorrect as it does not involve a direct connection between the bladder and the vagina.

Correct Answer: A

Rationale: The correct answer is Gastroduodenostomy. Billroth I procedure involves the removal of a part of the stomach (usually the distal portion) and anastomosis of the remaining stomach to the duodenum. This procedure is known as Gastroduodenostomy. Choices B, C, and D are incorrect as they refer to different surgical procedures involving connections with the jejunum, ileum, and creating an opening in the stomach, respectively, not the specific procedure described as Billroth I.

Correct Answer: A

Rationale: Assisting the client in pre-planning for alopecia is the best method to help them manage the psychosocial impact of the issue. By helping clients anticipate and prepare for the challenges associated with alopecia, they can cope better with the psychological impact. Reassuring the client that alopecia is temporary (choice B) may provide false hope as some types of alopecia are permanent. Teaching ways to protect the scalp (choice C) is important but not the most effective method for managing the psychosocial impact. Telling the client that there are worse side effects (choice D) is dismissive of the client's feelings and not helpful in addressing the psychosocial impact of alopecia.
