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. A client with syndrome of inappropriate antidiuretic hormone (SIADH) is at risk for which of the following complications?

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

Correct answer: B

Rationale: The correct answer is B: Hyponatremia. Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by the excessive release of antidiuretic hormone (ADH), leading to water retention in the body. This causes dilutional hyponatremia, where the sodium levels in the blood become abnormally low. Option A, Hypernatremia, is incorrect because SIADH does not cause elevated sodium levels. Option C, Hyperkalemia, is incorrect as SIADH does not directly affect potassium levels. Option D, Hypercalcemia, is also incorrect as SIADH does not impact calcium levels.

3. The nurse is caring for a client with Addison's disease. The client exhibits signs of hypotension, dehydration, and confusion. The nurse should anticipate administering which of the following medications?

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

Correct answer: B

Rationale: In Addison's disease, the adrenal glands do not produce enough cortisol. Hydrocortisone is a glucocorticoid medication that is used to replace deficient cortisol levels in patients with Addison's disease. It helps stabilize blood pressure and fluid balance. Insulin (Choice A) is used to manage diabetes, not Addison's disease. Levothyroxine (Choice C) is a thyroid hormone replacement used to treat hypothyroidism, not Addison's disease. Methimazole (Choice D) is used in the treatment of hyperthyroidism, not Addison's disease.

4. Which of the following is a priority nursing diagnosis for a client with Addison's disease?

• A. Fluid volume deficit
• B. Risk for infection
• C. Imbalanced nutrition: Less than body requirements
• D. Disturbed body image

Correct answer: A

Rationale: The priority nursing diagnosis for a client with Addison's disease is 'Fluid volume deficit.' Addison's disease is characterized by adrenal insufficiency, resulting in decreased aldosterone production. Aldosterone plays a key role in sodium and water retention in the body. With its deficiency, there is an increased risk of dehydration and electrolyte imbalance, leading to fluid volume deficit. While infection risk, nutrition issues, and body image disturbances are also important considerations for holistic care, addressing the fluid volume deficit takes precedence due to the immediate physiological impact on the client's health and well-being.

5. The client has been vomiting and has had numerous episodes of diarrhea. Which laboratory test should the nurse monitor?

• A. Serum calcium.
• B. Serum phosphorus.
• C. Serum potassium.
• D. Serum sodium.

Correct answer: C

Rationale: During episodes of vomiting and diarrhea, there is a risk of significant potassium loss, leading to potential electrolyte imbalances. Monitoring serum potassium levels is crucial in this situation to assess and manage any abnormalities promptly. Serum calcium (Choice A) is not typically affected by vomiting and diarrhea. Serum phosphorus (Choice B) levels are not commonly altered by these symptoms. Serum sodium (Choice D) may be affected in severe cases of dehydration, but potassium monitoring is a higher priority due to its potential for rapid depletion in vomiting and diarrhea.
