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. What is the approximate duration of action for intermediate-acting insulins like NPH?

• A. 6-8 hours.
• B. 10-14 hours.
• C. 16-20 hours.
• D. 24-28 hours.

Correct answer: C

Rationale: The correct answer is C: '16-20 hours.' Intermediate-acting insulins like NPH typically have a duration of action of approximately 16-20 hours. This prolonged action makes them effective in managing blood glucose levels over an extended period. Choices A, B, and D are incorrect because they do not align with the typical duration of action for intermediate-acting insulins. Choice A (6-8 hours) is too short, choice B (10-14 hours) is also shorter than the typical duration, and choice D (24-28 hours) is too long for intermediate-acting insulins like NPH.

3. The healthcare professional is educating a client with Cushing's syndrome about dietary management. Which of the following instructions should the healthcare professional include?

• A. Increase sodium intake
• B. Limit protein intake
• C. Limit calcium intake
• D. Increase potassium intake

Correct answer: D

Rationale: For clients with Cushing's syndrome, they are at risk of developing hypokalemia due to increased excretion of potassium. Therefore, it is essential to advise them to increase their potassium intake. Choices A, B, and C are incorrect because: A) Increasing sodium intake can worsen fluid retention and hypertension common in Cushing's syndrome. B) Limiting protein intake is not necessary unless there are specific kidney issues that require protein restriction. C) Limiting calcium intake is not typically recommended unless there are underlying conditions such as hypercalcemia.

4. Effective leaders must communicate a vision for the future. Which of the following is the best method for communicating a vision for the future?

• A. Involve others in creating the vision and connect daily work tasks to the vision.
• B. Encourage staff nurses to openly discuss practice and possible improvements.
• C. Critically analyze and discuss advances in practice with other nurses on staff.
• D. Actively listen to the recommendations of others.

Correct answer: A

Rationale: The best method for communicating a vision for the future is to involve others in creating the vision and connect daily work tasks to the vision. This approach fosters ownership and commitment among team members, as they feel part of the vision-building process and understand how their daily tasks contribute to achieving that vision. Choice B, encouraging staff nurses to openly discuss practice and possible improvements, is important for fostering communication but doesn't directly address creating and communicating a vision. Choice C, critically analyzing and discussing advances in practice with other nurses, focuses on professional development and knowledge sharing rather than specifically communicating a future vision. Choice D, actively listening to recommendations, is valuable for gathering input but may not be sufficient on its own for effectively communicating a future vision.

5. Which nursing diagnosis takes the highest priority for a female client with hyperthyroidism?

• A. Risk for imbalanced nutrition: More than body requirements related to thyroid hormone excess
• B. Risk for impaired skin integrity related to edema, skin fragility, and poor wound healing
• C. Body image disturbance related to weight gain and edema
• D. Imbalanced nutrition: Less than body requirements related to thyroid hormone excess

Correct answer: D

Rationale: The correct answer is D: Imbalanced nutrition: Less than body requirements related to thyroid hormone excess. In hyperthyroidism, increased metabolic rate leads to increased nutritional needs, causing weight loss and muscle wasting. Therefore, addressing imbalanced nutrition due to excessive thyroid hormone is a priority. Choice A is incorrect as hyperthyroidism typically leads to weight loss, not weight gain. Choice B is less of a priority as skin issues are secondary to the metabolic disturbances caused by hyperthyroidism. Choice C, body image disturbance, is important but addressing the client's nutritional needs should take precedence to prevent further complications.
