Nursing Elites

1. 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.

2. A client with Addison's disease is experiencing an Addisonian crisis. The nurse should expect to administer which of the following medication?

• A. Insulin
• B. Hydrocortisone
• C. Levothyroxine
• D. Methimazole

Correct answer: B

Rationale: During an Addisonian crisis, the adrenal glands are not producing enough cortisol, leading to a life-threatening situation. Hydrocortisone, a glucocorticoid, is the medication of choice in managing an Addisonian crisis. It helps replace deficient cortisol levels, stabilize blood pressure, and prevent further complications. Insulin (Choice A) is not indicated in Addison's disease unless specifically needed for diabetes management. Levothyroxine (Choice C) is used in hypothyroidism, not in Addison's disease. Methimazole (Choice D) is used to manage hyperthyroidism, which is not related to Addison's disease or its crisis.

3. The client has hyperparathyroidism. Which of the following dietary instructions should the nurse provide?

• A. Increase calcium intake
• B. Limit phosphorus intake
• C. Increase fluid intake
• D. Limit vitamin D intake

Correct answer: C

Rationale: The correct answer is to 'Increase fluid intake.' This is because increasing fluid intake helps prevent kidney stones, a common complication of hyperparathyroidism. While calcium is involved in the condition, increasing calcium intake is not recommended as it can exacerbate hypercalcemia, which is commonly present in hyperparathyroidism. Limiting phosphorus intake is not directly related to managing hyperparathyroidism. Limiting vitamin D intake is also not typically necessary in managing hyperparathyroidism, as it is usually a calcium and PTH-related issue.

4. Nurse Wayne is aware that a positive Chvostek's sign indicates:

• A. Hypocalcemia
• B. Hyponatremia
• C. Hypokalemia
• D. Hypermagnesemia

Correct answer: A

Rationale: A positive Chvostek's sign indicates hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching due to increased neuromuscular irritability from low calcium levels. Hyponatremia (Choice B) is characterized by low sodium levels, but it does not present with Chvostek's sign. Hypokalemia (Choice C) is low potassium levels, and hypermagnesemia (Choice D) is high magnesium levels, neither of which are associated with Chvostek's sign.

5. 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.
