Nursing Elites

1. In a male client with a history of hypertension diagnosed with primary hyperaldosteronism, the hypertension is caused by excessive hormone secretion from which of the following glands?

• A. Adrenal cortex
• B. Pancreas
• C. Adrenal medulla
• D. Parathyroid

Correct answer: A

Rationale: Primary hyperaldosteronism is characterized by excessive secretion of aldosterone from the adrenal cortex. Aldosterone, a hormone produced by the adrenal cortex, plays a crucial role in regulating blood pressure by promoting sodium and water retention in the kidneys. The adrenal medulla secretes catecholamines like epinephrine and norepinephrine, which are involved in the 'fight or flight' response, not in regulating blood pressure. The pancreas secretes insulin and glucagon, hormones involved in blood sugar regulation, not blood pressure. The parathyroid glands regulate calcium levels in the blood, not blood pressure.

2. The healthcare provider is monitoring a client with diabetic ketoacidosis (DKA). Which of the following laboratory findings would be expected?

• A. Decreased blood glucose levels
• B. Decreased urine ketones
• C. Increased serum bicarbonate
• D. Increased anion gap

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.

3. A client with DM is experiencing symptoms of hypoglycemia. Which action should the nurse take first?

• A. Give the client a glass of orange juice.
• B. Administer insulin as ordered.
• C. Check the client's blood glucose level.
• D. Notify the healthcare provider.

Correct answer: C

Rationale: The correct first action when a client with DM is experiencing symptoms of hypoglycemia is to check the client's blood glucose level. This step is crucial to confirm hypoglycemia before initiating any treatment. Giving the client orange juice (Choice A) is a common intervention for treating hypoglycemia, but it should not be done before confirming the blood glucose level. Administering insulin (Choice B) is not appropriate for hypoglycemia as it would further decrease the blood glucose levels. Notifying the healthcare provider (Choice D) can be important, but the immediate priority is to assess the blood glucose level to guide treatment.

4. A client with Cushing's syndrome is scheduled for surgery to remove an adrenal tumor. The nurse should monitor for which of the following complications postoperatively?

• A. Hyperglycemia
• B. Hypotension
• C. Hypokalemia
• D. Hyponatremia

Correct answer: B

Rationale: Postoperative hypotension is a common complication after adrenal tumor removal in a client with Cushing's syndrome. This occurs due to the sudden withdrawal of cortisol, which leads to a relative adrenal insufficiency state. Hyperglycemia (Choice A) is more common preoperatively due to excessive cortisol levels. Hypokalemia (Choice C) and Hyponatremia (Choice D) are also associated with Cushing's syndrome but are less likely to be immediate postoperative complications compared to hypotension.

5. An external insulin pump is prescribed for a client with DM. The client asks the nurse about the functioning of the pump. The nurse bases the response on the information that the pump:

• A. Gives small continuous doses of regular insulin subcutaneously, and the client can self-administer a bolus with an additional dosage from the pump before each meal.
• B. Is timed to release programmed doses of regular or NPH insulin into the bloodstream at specific intervals.
• C. Is surgically attached to the pancreas and infuses regular insulin into the pancreas, which in turn releases the insulin into the bloodstream.
• D. Continuously infuses small amounts of NPH insulin into the bloodstream while regularly monitoring blood glucose levels.

Correct answer: A

Rationale: The correct answer is A. An external insulin pump delivers small continuous doses of regular insulin subcutaneously throughout the day to meet the basal insulin needs. The client can also self-administer a bolus dose with an additional dosage from the pump before each meal to cover the mealtime insulin needs. Option B is incorrect as insulin pumps do not typically release programmed doses of insulin into the bloodstream at specific intervals; instead, they infuse insulin subcutaneously. Option C is incorrect as insulin pumps are not surgically attached to the pancreas; they are worn externally. Option D is incorrect as NPH insulin is not commonly used in insulin pumps, and the pumps do not continuously infuse insulin directly into the bloodstream but rather subcutaneously.
