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. A client with hyperthyroidism is being treated with radioactive iodine. The nurse should teach the client to expect which of the following side effects?

• A. Increased heart rate
• B. Hypothyroidism
• C. Hypercalcemia
• D. Weight loss

Correct answer: B

Rationale: When a client with hyperthyroidism undergoes radioactive iodine treatment, it often leads to hypothyroidism due to the destruction of thyroid tissue. This occurs as a desired outcome of the treatment to reduce the overactive thyroid function. Choices A, C, and D are incorrect. Increased heart rate, hypercalcemia, and weight loss are not expected side effects of radioactive iodine treatment for hyperthyroidism. Instead, the goal is to suppress the overactive thyroid, leading to a hypothyroid state.

3. Which of the following statements is true regarding followership and leadership?

• A. Effective leadership is more important than followership.
• B. Good leaders do not need to be good followers.
• C. A good follower is not just skilled but also self-directed.
• D. Critical thinking is only required for effective leadership.

Correct answer: C

Rationale: The correct answer is C: 'A good follower is not just skilled but also self-directed.' This statement is true as being self-directed complements effective leadership. Good followers possess the ability to take initiative, work independently, and contribute positively to a team without constant supervision. Option A is incorrect because followership is equally important as leadership in achieving group success. Option B is incorrect as good leaders often demonstrate qualities of good followership, such as being able to listen, collaborate, and support others. Option D is incorrect because critical thinking is essential for both effective leadership and followership, not exclusively for leadership roles.

4. The nurse is caring for a client with myxedema coma. Which of the following interventions should the nurse prioritize?

• A. Administer intravenous fluids
• B. Provide a warming blanket
• C. Administer levothyroxine intravenously
• D. Place the client in Trendelenburg position

Correct answer: C

Rationale: In myxedema coma, the priority intervention is to administer levothyroxine intravenously. Myxedema coma is a severe form of hypothyroidism, and intravenous levothyroxine is crucial to rapidly replace deficient thyroid hormones. Administering intravenous fluids (choice A) may be necessary, but levothyroxine takes precedence. Providing a warming blanket (choice B) can help maintain the client's body temperature, but it does not address the underlying thyroid hormone deficiency. Placing the client in Trendelenburg position (choice D) is not indicated and can potentially worsen the client's condition.

5. The client with DM is being taught about the signs of hyperglycemia. Which symptom should the nurse include?

• A. Excessive thirst
• B. Sweating
• C. Shaking
• D. Hunger

Correct answer: A

Rationale: Excessive thirst, also known as polydipsia, is a hallmark symptom of hyperglycemia. When blood glucose levels are high, the body tries to eliminate the excess glucose through urine, leading to increased urination and subsequent thirst. Sweating, shaking, and hunger are more commonly associated with hypoglycemia, not hyperglycemia. Sweating can occur when blood sugar levels drop too low, shaking is a sign of hypoglycemia, and hunger is often a result of low blood sugar levels triggering the body to seek fuel.
