Nursing Elites

1. In a male client with a history of hypertension diagnosed with primary hyperaldosteronism, the hypertension is caused by excessive hormone secretion from which of the following glands?

• A. Adrenal cortex
• B. Pancreas
• C. Adrenal medulla
• D. Parathyroid

Correct answer: A

Rationale: Primary hyperaldosteronism is characterized by excessive secretion of aldosterone from the adrenal cortex. Aldosterone, a hormone produced by the adrenal cortex, plays a crucial role in regulating blood pressure by promoting sodium and water retention in the kidneys. The adrenal medulla secretes catecholamines like epinephrine and norepinephrine, which are involved in the 'fight or flight' response, not in regulating blood pressure. The pancreas secretes insulin and glucagon, hormones involved in blood sugar regulation, not blood pressure. The parathyroid glands regulate calcium levels in the blood, not blood pressure.

2. The healthcare provider is assessing a client with suspected syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following laboratory findings is most consistent with this condition?

• A. Increased serum sodium
• B. Decreased urine specific gravity
• C. Decreased serum osmolality
• D. Increased serum potassium

Correct answer: C

Rationale: The correct answer is C: Decreased serum osmolality. Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by the excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. The dilution of sodium results in decreased serum osmolality. Option A is incorrect because SIADH causes hyponatremia, resulting in decreased serum sodium levels. Option B is incorrect because SIADH leads to concentrated urine with increased urine specific gravity. Option D is incorrect as SIADH does not typically affect serum potassium levels.

3. A client with hyperparathyroidism is receiving dietary instructions. Which of the following foods should the client avoid?

• A. Milk
• B. Bananas
• C. Spinach
• D. Processed meats

Correct answer: A

Rationale: In hyperparathyroidism, there are already elevated calcium levels in the body. Therefore, clients should avoid high-calcium foods like milk to prevent further increase in calcium levels. Bananas, spinach, and processed meats do not have significant calcium content and do not need to be avoided specifically in hyperparathyroidism.

4. A client with diabetes insipidus is receiving desmopressin therapy. The nurse should monitor for which of the following potential side effects?

• A. Hyponatremia
• B. Hypernatremia
• C. Hypokalemia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is A: Hyponatremia. Desmopressin, a medication used to treat diabetes insipidus, can cause the retention of water without sodium, leading to dilutional hyponatremia. This occurs because desmopressin increases water reabsorption in the kidneys without affecting sodium levels. Hypernatremia (choice B) is unlikely because desmopressin does not cause excessive sodium retention. Hypokalemia (choice C) and hypercalcemia (choice D) are not typically associated with desmopressin therapy for diabetes insipidus.

5. 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.
