Correct Answer: B

Rationale: The correct answer is B, Diabetes insipidus. Diabetes insipidus can develop after a head injury due to damage to the hypothalamus or pituitary gland, leading to a deficiency in antidiuretic hormone (ADH). Pheochromocytoma (choice A) is a tumor of the adrenal gland and is not directly related to closed head injury or increased intracranial pressure. Hashimoto's disease (choice C) is an autoimmune disorder affecting the thyroid gland, not commonly associated with head injuries. Gynecomastia (choice D) is the development of breast tissue in males and is not an endocrine disorder typically linked to closed head injuries.

Correct Answer: D

Rationale: The correct interventions for a client with peripheral vascular disease include keeping the area between the toes dry and wearing comfortable, well-fitting shoes. Choice A is correct as moisture between the toes can lead to skin breakdown and infection. Choice B is also correct as proper footwear helps prevent injury and promotes circulation. Choice C, cutting toenails straight across, is incorrect for peripheral vascular disease clients as cutting them in an arch can reduce the risk of ingrown toenails, which is important for clients with diabetes to prevent complications. Therefore, choices A and B are the most appropriate interventions for the client with peripheral vascular disease.

Correct Answer: A

Rationale: The correct answer is A: One medium baked potato. Potatoes are high in potassium, which is crucial for clients on furosemide (Lasix) to prevent hypokalemia, as furosemide can cause potassium loss. White bread (choice B) and scrambled egg (choice D) are not high-potassium foods and do not address the specific need related to furosemide therapy. While apples (choice C) contain some potassium, they are not as rich in potassium as a baked potato, making them a less optimal choice for a client on furosemide.

Correct Answer: D

Rationale: The nurse's first priority in this situation is to ensure the client's safety by initiating suicide precautions. This involves removing any potential means of self-harm and closely monitoring the client to prevent further attempts. While establishing rapport and communication are important, safety is paramount at this critical juncture. Placing the client in full restraints should be avoided unless absolutely necessary for immediate safety concerns.

Correct Answer: C

Rationale: The correct answer is C: Implementation. In nursing care, implementation involves carrying out and supervising the planned procedures for the patient. This step focuses on putting the care plan into action. Choice A, Evaluation, involves assessing the effectiveness of the care provided, not performing procedures. Choice B, Planning, is about developing a plan of care, not executing it. Choice D, Assessment, is the initial step in the nursing process where data is collected and analyzed to determine the patient's needs, not the step involving performing and supervising procedures.
