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 nurse caring for a group of clients reviews the electrolyte laboratory results and notes a potassium level of 5.5 mEq/L on one client's laboratory report. The nurse understands that which client is at highest risk for the development of a potassium value at this level?

• A. The client with colitis
• B. The client with Cushing's syndrome
• C. The client who has been overusing laxatives
• D. The client who has sustained a traumatic burn

Correct answer: D

Rationale: Clients who have sustained traumatic burns are at a higher risk of developing hyperkalemia due to cell lysis. When cells are damaged in a traumatic burn, potassium can leak out from the intracellular space into the bloodstream, leading to elevated serum potassium levels. Colitis, Cushing's syndrome, and overuse of laxatives are not typically associated with the same degree of cell damage or potassium shifts seen in traumatic burns, making them less likely to result in such high potassium levels.

3. A female adult client with a history of chronic hyperparathyroidism admits to being noncompliant. Based on initial assessment findings, the nurse formulates the nursing diagnosis of Risk for injury. To complete the nursing diagnosis statement for this client, which 'related-to' phrase should the nurse add?

• A. Related to bone demineralization resulting in pathologic fractures
• B. Related to exhaustion secondary to an accelerated metabolic rate
• C. Related to edema and dry skin secondary to fluid infiltration into the interstitial spaces
• D. Related to tetany secondary to a decreased serum calcium level

Correct answer: A

Rationale: The correct answer is A: 'Related to bone demineralization resulting in pathologic fractures.' In chronic hyperparathyroidism, bone demineralization occurs due to the excessive release of parathyroid hormone, leading to increased calcium resorption from bones. This process weakens the bones, making the client prone to pathologic fractures. Choices B, C, and D are incorrect because they do not directly relate to the increased risk of injury associated with chronic hyperparathyroidism. Exhaustion, edema, dry skin, and tetany are not the primary risks for injury in this client population.

4. 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.

5. How often should rotation sites for insulin injection be separated from one another?

• A. Every third day.
• B. Every week.
• C. Every 2-3 weeks.
• D. Every 2-4 weeks.

Correct answer: C

Rationale: Insulin injection sites should be rotated every 2-3 weeks to prevent lipodystrophy and ensure proper insulin absorption. Option A ('Every third day') is too frequent and does not allow enough time for the previous site to heal properly. Option B ('Every week') might not provide adequate time for the tissue to recover. Option D ('Every 2-4 weeks') could potentially lead to overuse of a single injection site, increasing the risk of lipodystrophy and inconsistent insulin absorption. Therefore, the recommended interval of every 2-3 weeks is optimal for insulin injection site rotation.
