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 nurse is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following interventions should the nurse implement?

• A. Encourage increased fluid intake
• B. Administer vasopressin
• C. Monitor for signs of dehydration
• D. Restrict oral fluids

Correct answer: D

Rationale: The correct intervention for a client with syndrome of inappropriate antidiuretic hormone (SIADH) is to restrict oral fluids. SIADH leads to excessive release of antidiuretic hormone (ADH), causing the body to retain water and diluting the sodium levels in the blood (hyponatremia). Restricting oral fluids helps prevent further water retention and worsening hyponatremia. Encouraging increased fluid intake (choice A) would exacerbate the problem by further diluting sodium levels. Administering vasopressin (choice B) is not indicated in SIADH, as the condition is characterized by excess ADH secretion. Monitoring for signs of dehydration (choice C) is not the priority in SIADH since the issue is water retention rather than dehydration.

3. 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.

4. Capillary glucose monitoring is being performed every 4 hours for a female client diagnosed with diabetic ketoacidosis. Insulin is administered using a scale of regular insulin according to glucose results. At 2 p.m., the client has a capillary glucose level of 250 mg/dl for which she receives 8 U of regular insulin. Nurse Vince should expect the dose's:

• A. Onset to be at 2 p.m. and its peak to be at 3 p.m.
• B. Onset to be at 2:15 p.m. and its peak to be at 3 p.m.
• C. Onset to be at 2:30 p.m. and its peak to be at 4 p.m.
• D. Onset to be at 4 p.m. and its peak to be at 6 p.m.

Correct answer: C

Rationale: The correct answer is C. Regular insulin typically has an onset of action within 30 minutes and peaks 2-4 hours after administration. Given that the insulin was administered at 2 p.m., the onset of action can be expected around 2:30 p.m., and the peak effect would occur between 4-6 p.m. Choice A is incorrect as the onset and peak are too close together for regular insulin. Choice B is incorrect because the onset time is too soon after administration. Choice D is incorrect as the onset time is too delayed for regular insulin.

5. The healthcare provider is assessing a client with hypothyroidism. Which of the following clinical findings would the healthcare provider expect?

• A. Tachycardia
• B. Weight loss
• C. Cold intolerance
• D. Diaphoresis

Correct answer: C

Rationale: Cold intolerance is a classic symptom of hypothyroidism. In hypothyroidism, the body's metabolic rate is decreased, leading to a reduced ability to regulate body temperature. As a result, individuals with hypothyroidism often feel cold, especially in their extremities. Tachycardia (A) is more commonly associated with hyperthyroidism due to the increased metabolic rate. Weight loss (B) is also a typical finding in hyperthyroidism, as the body burns calories at a faster rate. Diaphoresis (D), excessive sweating, is not a typical symptom of hypothyroidism.
