Nursing Elites

1. Nurse Louie is developing a teaching plan for a male client diagnosed with diabetes insipidus. The nurse should include information about which hormone lacking in clients with diabetes insipidus?

• A. Antidiuretic hormone (ADH)
• B. Thyroid-stimulating hormone (TSH)
• C. Follicle-stimulating hormone (FSH)
• D. Luteinizing hormone (LH)

Correct answer: A

Rationale: Diabetes insipidus is a condition characterized by a deficiency of antidiuretic hormone (ADH). ADH plays a crucial role in regulating water balance by controlling the amount of water reabsorbed by the kidneys. Options B, C, and D are incorrect as they are not associated with diabetes insipidus. TSH (thyroid-stimulating hormone) is responsible for regulating thyroid function, while FSH (follicle-stimulating hormone) and LH (luteinizing hormone) are involved in reproductive functions.

2. A client with hyperthyroidism is prescribed methimazole. The nurse should instruct the client that the purpose of this medication is to:

• A. Decrease thyroid hormone production
• B. Increase thyroid hormone production
• C. Suppress the immune system
• D. Prevent thyroid storm

Correct answer: A

Rationale: The correct answer is A: Decrease thyroid hormone production. Methimazole works by inhibiting the synthesis of thyroid hormones, specifically by blocking the enzyme responsible for this process. By reducing the production of thyroid hormones, methimazole helps to normalize the elevated levels seen in hyperthyroidism. Choices B, C, and D are incorrect. Choice B, 'Increase thyroid hormone production,' is inaccurate as methimazole actually decreases thyroid hormone production. Choice C, 'Suppress the immune system,' is unrelated to the mechanism of action of methimazole. Choice D, 'Prevent thyroid storm,' is not the primary purpose of methimazole; while it may help prevent worsening of hyperthyroidism, its main action is to reduce thyroid hormone levels.

3. The healthcare provider is monitoring a client with diabetic ketoacidosis (DKA). Which of the following laboratory findings would be expected?

• A. Decreased blood glucose levels
• B. Decreased urine ketones
• C. Increased serum bicarbonate
• D. Increased anion gap

Correct answer: D

Rationale: In diabetic ketoacidosis (DKA), there is an excess of ketone bodies produced due to the breakdown of fatty acids for energy, leading to metabolic acidosis. An increased anion gap is a characteristic laboratory finding in DKA. The increased anion gap is a result of the accumulation of ketoacids and lactic acid in the blood, contributing to metabolic acidosis. Therefore, the correct answer is an increased anion gap. Choices A, B, and C are incorrect because in DKA, blood glucose levels are typically elevated, urine ketones are increased due to the breakdown of fatty acids, and serum bicarbonate is usually decreased as it is consumed in an attempt to buffer the acidosis.

4. A client with Addison's disease is at risk for which of the following complications?

• A. Hypertension
• B. Hypovolemia
• C. Hypernatremia
• D. Hypokalemia

Correct answer: B

Rationale: A client with Addison's disease is at risk for hypovolemia. Addison's disease is characterized by adrenal insufficiency, particularly cortisol and aldosterone deficiency. Aldosterone deficiency leads to impaired sodium and water retention, resulting in decreased blood volume and hypovolemia. This condition can cause hypotension, not hypertension (Choice A), as reduced blood volume leads to decreased pressure. Hypernatremia (Choice C) is unlikely in Addison's disease because of the loss of sodium along with water in hypovolemia. Hypokalemia (Choice D) can occur due to aldosterone deficiency, but it is not the primary complication associated with Addison's disease.

5. Which of the following clinical findings would be most concerning in a client with hypothyroidism?

• A. Bradycardia
• B. Dry skin
• C. Constipation
• D. Depression

Correct answer: A

Rationale: Bradycardia in a client with hypothyroidism is the most concerning finding as it may indicate severe hypothyroidism, leading to decreased heart rate. Bradycardia can be a sign of myxedema coma, a life-threatening condition that requires immediate medical attention. Dry skin, constipation, and depression are common symptoms associated with hypothyroidism but are not as acutely concerning as bradycardia.
