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 type 1 diabetes mellitus is admitted to the hospital with diabetic ketoacidosis (DKA). Which of the following interventions should the nurse implement first?

• A. Administer intravenous insulin
• B. Start an intravenous line and infuse normal saline
• C. Monitor serum potassium levels
• D. Obtain an arterial blood gas (ABG)

Correct answer: B

Rationale: The correct first intervention in the treatment of a client with diabetic ketoacidosis (DKA) is to start an intravenous line and infuse normal saline. This is essential for fluid resuscitation to restore intravascular volume and improve perfusion. Administering intravenous insulin can lead to further potassium depletion without first addressing dehydration and electrolyte imbalances. Monitoring serum potassium levels is important but should follow fluid resuscitation to avoid life-threatening hypokalemia. Obtaining an arterial blood gas (ABG) is necessary to assess the acid-base status but is not the initial priority when managing DKA.

3. A client with type 2 diabetes mellitus is being educated on foot care. Which of the following instructions should the nurse provide?

• A. Soak your feet in warm water daily.
• B. Avoid going barefoot to protect your feet.
• C. Inspect your feet daily for any cuts or sores.
• D. Avoid using a heating pad to warm your feet if they are cold.

Correct answer: C

Rationale: The correct instruction for a client with type 2 diabetes mellitus regarding foot care is to inspect their feet daily for any cuts or sores. This practice helps in early detection of potential issues like cuts, sores, or infections, which can be challenging to heal due to poor circulation in diabetes. Choice A is incorrect because soaking feet in hot water can lead to burns or skin damage, especially for individuals with diabetes who may have reduced sensation. Choice B is incorrect because going barefoot increases the risk of injuries and infections for individuals with diabetes. Choice D is incorrect because using a heating pad can also impair sensation, increasing the risk of burns or injuries for diabetic individuals.

4. A client with Addison's disease is receiving corticosteroid therapy. The nurse should monitor for which of the following potential side effects?

• A. Hypoglycemia
• B. Hyperkalemia
• C. Hyperglycemia
• D. Hyponatremia

Correct answer: C

Rationale: The correct answer is C, Hyperglycemia. Corticosteroid therapy can lead to hyperglycemia by increasing blood glucose levels. Corticosteroids can induce insulin resistance, decrease glucose uptake by tissues, and promote gluconeogenesis. While corticosteroid therapy can cause hypoglycemia in some cases, it is more commonly associated with hyperglycemia. Hyperkalemia (choice B) is more commonly associated with conditions like renal failure or certain medications. Hyponatremia (choice D) is typically not a common side effect of corticosteroid therapy unless there are other contributing factors present.

5. What is the approximate duration of action for intermediate-acting insulins like NPH?

• A. 6-8 hours.
• B. 10-14 hours.
• C. 16-20 hours.
• D. 24-28 hours.

Correct answer: C

Rationale: The correct answer is C: '16-20 hours.' Intermediate-acting insulins like NPH typically have a duration of action of approximately 16-20 hours. This prolonged action makes them effective in managing blood glucose levels over an extended period. Choices A, B, and D are incorrect because they do not align with the typical duration of action for intermediate-acting insulins. Choice A (6-8 hours) is too short, choice B (10-14 hours) is also shorter than the typical duration, and choice D (24-28 hours) is too long for intermediate-acting insulins like NPH.
