Nursing Elites

1. The nurse is caring for a client with primary adrenal insufficiency (Addison's disease). Which of the following laboratory findings would the nurse expect?

• A. Hypernatremia
• B. Hyperkalemia
• C. Hyperglycemia
• D. Hypercalcemia

Correct answer: B

Rationale: In primary adrenal insufficiency (Addison's disease), there is a decrease in aldosterone levels, leading to sodium loss and potassium retention. This imbalance results in hyperkalemia, making choice B the correct answer. Hypernatremia (choice A) is unlikely due to sodium loss. Hyperglycemia (choice C) and hypercalcemia (choice D) are not typically associated with primary adrenal insufficiency.

2. 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.

3. Which of these signs suggests that a male client with the syndrome of inappropriate antidiuretic hormone (SIADH) secretion is experiencing complications?

• A. Tetanic contractions
• B. Neck vein distention
• C. Weight loss
• D. Polyuria

Correct answer: B

Rationale: Neck vein distention is a sign of fluid overload, a complication of SIADH due to water retention. Tetanic contractions (Choice A) are not typically associated with SIADH. Weight loss (Choice C) is not a common complication of SIADH, as patients often experience fluid retention and weight gain. Polyuria (Choice D) is also not a typical sign of SIADH, as the condition is characterized by water retention and decreased urine output.

4. The nurse is caring for a client with hyperaldosteronism. Which of the following laboratory results would the nurse expect?

• A. Hypokalemia
• B. Hypernatremia
• C. Hyperkalemia
• D. Hypocalcemia

Correct answer: A

Rationale: In hyperaldosteronism, there is an excess of aldosterone production, leading to increased sodium retention and potassium excretion by the kidneys. This results in hypokalemia (low potassium levels). Therefore, the correct answer is hypokalemia (Choice A). Hypernatremia (Choice B) is an incorrect choice as hyperaldosteronism primarily affects potassium and not sodium levels. Hyperkalemia (Choice C) is also incorrect because hyperaldosteronism causes potassium excretion, leading to low levels. Hypocalcemia (Choice D) is not typically associated with hyperaldosteronism; instead, it is more related to conditions affecting calcium regulation.

5. A client with Graves' disease is prescribed propranolol. The nurse understands that the purpose of this medication is to:

• A. Treat the underlying cause of the disease
• B. Reduce thyroid hormone production
• C. Alleviate symptoms such as tachycardia and tremors
• D. Increase energy levels

Correct answer: C

Rationale: The correct answer is C: Alleviate symptoms such as tachycardia and tremors. Propranolol is a beta-blocker that helps manage symptoms like tachycardia (fast heart rate) and tremors in patients with Graves' disease. Choice A is incorrect because propranolol does not address the underlying cause of Graves' disease, which is autoimmune in nature. Choice B is incorrect because propranolol does not directly reduce thyroid hormone production; it mainly targets the symptoms. Choice D is incorrect because while propranolol may help with symptoms like tachycardia, it is not intended to increase energy levels.
