Correct Answer: D

Rationale: The correct answer is D: Decrease the intake of trace elements and antioxidant supplements. Clients with HIV/AIDS do not require additional trace elements and antioxidant supplements, as excessive intake can be harmful. HIV/AIDS already places stress on the immune system, so taking excessive supplements may lead to toxicity. It is important to focus on a balanced diet rich in essential nutrients rather than overloading the body with unnecessary supplements. Encouraging a healthy, balanced diet will help support overall health and immune function in clients with HIV/AIDS. Choices A, B, and C are incorrect because encouraging excessive intake of fat-soluble vitamins, water-soluble vitamins, iron, and zinc can also lead to potential adverse effects. It is important to focus on meeting the recommended daily allowances for these nutrients rather than exceeding them.

Correct Answer: D

Rationale: The correct answer is D: Dysphagia or hoarseness. In laryngeal cancer, dysphagia and hoarseness are early symptoms due to vocal cord involvement. Hoarseness results from vocal cord paralysis, while dysphagia occurs when the tumor obstructs the esophagus. Anemia and fatigue (choice A) are nonspecific symptoms seen in various conditions. A noticeable lump in the neck (choice B) typically indicates metastasis to the lymph nodes, which occurs later in laryngeal cancer. Crackles and stridor (choice C) are more associated with respiratory conditions rather than laryngeal cancer.

Correct Answer: C

Rationale: The correct answer is C because it addresses the specific nursing intervention needed to prepare Mr. RR for the brain scanning test. By explaining to Mr. RR that the test will not be painful and that his head will be supported in place, the nurse helps alleviate any potential anxiety or fear he may have. This information reassures the patient and ensures his cooperation during the procedure. Choice A is incorrect because discontinuing anticonvulsant therapy without medical approval could have serious consequences for Mr. RR's health. Choice B is also incorrect as obtaining consent is important, but it is not directly related to preparing Mr. RR for the test. Choice D is incorrect as it introduces potential negative outcomes without providing necessary information to prepare the patient for the test.

Correct Answer: B

Rationale: The correct answer is B: Develop good communication skills. In interdisciplinary collaboration, effective communication is essential for teamwork. By developing good communication skills, the nurse can effectively interact with other healthcare professionals to provide holistic care. Choice A is incorrect as the nurse should collaborate as part of a team, not necessarily be the leader. Choice C is incorrect as interdisciplinary collaboration involves working with professionals from various disciplines. Choice D is incorrect as conflict resolution is an important aspect of effective collaboration.

Correct Answer: A

Rationale: Step-by-step rationale for why choice A is correct: 1. Hypercalcemia can lead to dehydration due to increased urine output. 2. Encouraging 3 to 4 L of fluid daily helps prevent dehydration and promote renal excretion of excess calcium. 3. Adequate hydration reduces the risk of kidney stones and other complications associated with hypercalcemia. Summary of why other choices are incorrect: - Choice B (bed rest) does not directly address hypercalcemia complications. - Choice C (cough and deep breathe) is unrelated to managing hypercalcemia. - Choice D (apply heat to painful areas) does not address the underlying cause of hypercalcemia or its complications.
