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. Nurse Troy is aware that the most appropriate nursing diagnosis for a client with Addison's disease is:

• A. Risk for infection
• B. Excessive fluid volume
• C. Urinary retention
• D. Hypothermia

Correct answer: A

Rationale: The most appropriate nursing diagnosis for a client with Addison's disease is 'Risk for infection.' Addison's disease is characterized by corticosteroid deficiency, which leads to immune suppression, making these clients more susceptible to infections. This diagnosis reflects the increased vulnerability of clients with Addison's disease to infections. Choices B, C, and D are incorrect because Addison's disease does not typically present with excessive fluid volume, urinary retention, or hypothermia as primary concerns.

3. During preoperative teaching for a female client undergoing subtotal thyroidectomy, which statement should the nurse include?

• A. The head of your bed must remain flat for 24 hours after surgery.
• B. You should avoid deep breathing and coughing after surgery.
• C. You won't be able to swallow for the first day or two.
• D. You must avoid hyperextending your neck after surgery.

Correct answer: D

Rationale: The correct answer is D. Instructing the client to avoid hyperextending the neck after thyroid surgery is crucial to prevent stress on the surgical site and reduce the risk of complications such as strain on the incision or damage to the healing tissues. Choices A, B, and C are incorrect because: A) Keeping the head of the bed flat for 24 hours is not necessary after a thyroidectomy; elevation of the head of the bed can actually help reduce swelling and improve comfort. B) Encouraging deep breathing and coughing after surgery is essential to prevent respiratory complications such as pneumonia, so this advice is incorrect. C) Difficulty swallowing after thyroid surgery is not a typical outcome, so this statement is inaccurate and should not be included in the preoperative teaching.

4. A healthcare professional is monitoring a client newly diagnosed with DM for signs of complications. Which sign or symptom, if exhibited in the client, indicates that the client is at risk for chronic complications of diabetes if blood glucose levels are not adequately managed?

• A. Polyuria
• B. Diaphoresis
• C. Pedal edema
• D. Proteinuria

Correct answer: D

Rationale: Proteinuria is the correct answer because it indicates kidney damage, which is a common complication of uncontrolled diabetes. Elevated blood glucose levels over time can damage the kidneys, leading to proteinuria. Polyuria (excessive urination) is a symptom of diabetes but does not specifically indicate a risk for chronic complications. Diaphoresis (excessive sweating) and pedal edema (swelling of the lower limbs) are not direct indicators of chronic complications related to uncontrolled diabetes.

5. What clinical feature distinguishes a hypoglycemic reaction from a ketoacidosis reaction?

• A. Blurred vision.
• B. Diaphoresis.
• C. Nausea.
• D. Weakness.

Correct answer: B

Rationale: Diaphoresis is the correct answer because it is more characteristic of hypoglycemia. Hypoglycemia typically presents with symptoms such as diaphoresis (excessive sweating), palpitations, tremors, and anxiety. On the other hand, ketoacidosis is associated with symptoms such as fruity breath, deep and labored breathing (Kussmaul respirations), nausea, vomiting, and abdominal pain. Blurred vision can occur in both hypoglycemia and ketoacidosis due to metabolic disturbances affecting the eyes. Weakness is a nonspecific symptom that can be present in both conditions, making it less helpful in distinguishing between the two.
