Correct Answer: A

Rationale: The correct intervention for a client with pheochromocytoma is to administer beta-blockers to control blood pressure. Pheochromocytoma is a catecholamine-secreting tumor that can cause severe hypertension. Beta-blockers are used to block the effects of catecholamines and help control blood pressure in these clients. Encouraging a high-sodium diet (Choice B) would not be appropriate as it can worsen hypertension. Monitoring for signs of hyperglycemia (Choice C) is not directly related to managing pheochromocytoma. Restricting fluid intake (Choice D) may lead to dehydration and is not a recommended intervention for this condition.

Correct Answer: D

Rationale: A new nurse graduate should consider applying for a nurse manager position when they have developed both leadership and clinical expertise. This ensures that they are well-prepared for the responsibilities of the role. Choice A is incorrect because being comfortable in the current position does not necessarily equate to having the required skills for a nurse manager role. Choice B is incorrect as mentoring other new nurses, while valuable, may not directly align with the skills needed for a managerial position. Choice C is incorrect as applying for a nurse manager position solely because a position is available does not guarantee readiness for the role.

Correct Answer: D

Rationale: In diabetic ketoacidosis (DKA), there is an excess of ketone bodies produced due to the breakdown of fatty acids for energy, leading to metabolic acidosis. An increased anion gap is a characteristic laboratory finding in DKA. The increased anion gap is a result of the accumulation of ketoacids and lactic acid in the blood, contributing to metabolic acidosis. Therefore, the correct answer is an increased anion gap. Choices A, B, and C are incorrect because in DKA, blood glucose levels are typically elevated, urine ketones are increased due to the breakdown of fatty acids, and serum bicarbonate is usually decreased as it is consumed in an attempt to buffer the acidosis.

Correct Answer: C

Rationale: The correct answer is C: Processed meats. Clients with Cushing's syndrome who are on a low-sodium diet should avoid processed meats because they are typically high in sodium. Bananas, spinach, and oatmeal are generally low in sodium and can be included in a low-sodium diet. Bananas are a good source of potassium, spinach is rich in vitamins and minerals, and oatmeal is a healthy whole grain option. Therefore, choices A, B, and D are not the best options to avoid for a client with Cushing's syndrome following a low-sodium diet.

Correct Answer: C

Rationale: A DNR order is typically written after the healthcare provider has discussed the implications with the patient and their family. This ensures that the patient and family are fully informed before making such a critical decision. Choice A is incorrect because pronouncing clinical death is a medical determination, not directly related to DNR orders. Choice B is incorrect because while physicians commonly write DNR orders, the discussion with the patient and family is crucial. Choice D is incorrect because a DNR order does not require a court decision; it is a decision made in collaboration with the healthcare team and the patient or family.
