Nursing Elites

1. What is the mechanism of action of corticotropin (Acthar) when prescribed as replacement therapy for a male client who has undergone surgical removal of a pituitary tumor?

• A. It decreases cyclic adenosine monophosphate (cAMP) production and affects the metabolic rate of target organs.
• B. It interacts with plasma membrane receptors to inhibit enzymatic actions.
• C. It interacts with plasma membrane receptors to produce enzymatic actions that affect protein, fat, and carbohydrate metabolism.
• D. It regulates the threshold for water reabsorption in the kidneys.

Correct answer: C

Rationale: Corticotropin (ACTH) stimulates the adrenal cortex to secrete cortisol and other hormones, affecting protein, fat, and carbohydrate metabolism. Choice A is incorrect because corticotropin does not decrease cAMP production; instead, it stimulates enzymatic actions. Choice B is incorrect because corticotropin does not inhibit enzymatic actions but rather produces enzymatic actions. Choice D is incorrect because corticotropin's mechanism of action does not involve regulating the threshold for water reabsorption in the kidneys.

2. The nurse is caring for a client with a history of adrenal insufficiency. The nurse should monitor for which of the following signs of an Addisonian crisis?

• A. Hypertension
• B. Hyperglycemia
• C. Severe hypotension
• D. Tachycardia

Correct answer: C

Rationale: In an Addisonian crisis, there is a lack of adrenal hormones leading to severe hypotension. Hypertension (choice A) is not a typical sign of Addisonian crisis but can occur in conditions like pheochromocytoma. Hyperglycemia (choice B) is not a characteristic sign of an Addisonian crisis. Tachycardia (choice D) may occur as a compensatory mechanism in response to hypotension, but severe bradycardia is more common in an Addisonian crisis.

3. 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.

4. Which of the following is true about nursing ethics?

• A. Nursing ethics focus on the organizational level at the workplace.
• B. Nursing ethics focus on the moral character of nurses.
• C. Nursing ethics focus on the experiences and needs of patients.
• D. Nursing ethics focus on the ethical principles governing healthcare organizations.

Correct answer: B

Rationale: The correct answer is B. Nursing ethics primarily focus on the moral character of nurses, emphasizing principles, values, and virtues that guide their professional conduct. Choice A is incorrect as nursing ethics are more about individual moral decision-making than organizational practices. Choice C is incorrect because while nurses consider patients' experiences and needs, nursing ethics primarily revolve around the nurses themselves. Choice D is incorrect as nursing ethics are centered on the moral obligations and responsibilities of nurses, not specifically on the ethical principles governing healthcare organizations.

5. In a client with hypoparathyroidism, the nurse should expect which laboratory result?

• A. Increased calcium levels
• B. Decreased phosphorus levels
• C. Increased phosphorus levels
• D. Increased potassium levels

Correct answer: C

Rationale: In hypoparathyroidism, there is a deficiency of parathyroid hormone, leading to decreased calcium levels and increased phosphorus levels. Therefore, the correct answer is 'Increased phosphorus levels' (Choice C). Choice A, 'Increased calcium levels,' is incorrect because hypoparathyroidism is associated with low calcium levels. Choice B, 'Decreased phosphorus levels,' is incorrect as phosphorus levels are typically elevated in hypoparathyroidism. Choice D, 'Increased potassium levels,' is not directly related to hypoparathyroidism and is not an expected laboratory result in this condition.
