Nursing Elites

1. The healthcare provider is caring for a client with pheochromocytoma. Which of the following interventions should the healthcare provider implement?

• A. Administer beta-blockers to control blood pressure
• B. Encourage a high-sodium diet
• C. Monitor for signs of hyperglycemia
• D. Restrict fluid intake to prevent edema

Correct answer: A

Rationale: The correct intervention for a client with pheochromocytoma is to administer beta-blockers to control blood pressure. Pheochromocytoma is a catecholamine-secreting tumor that can cause severe hypertension. Beta-blockers are used to block the effects of catecholamines and help control blood pressure in these clients. Encouraging a high-sodium diet (Choice B) would not be appropriate as it can worsen hypertension. Monitoring for signs of hyperglycemia (Choice C) is not directly related to managing pheochromocytoma. Restricting fluid intake (Choice D) may lead to dehydration and is not a recommended intervention for this condition.

2. A nurse is preparing to administer NPH insulin to a client with DM. The nurse notes that the NPH insulin vial is cloudy. The nurse should:

• A. Obtain a new vial of NPH insulin.
• B. Draw up the cloudy insulin as ordered.
• C. Shake the vial vigorously before drawing up the insulin.
• D. Warm the insulin to room temperature before administration.

Correct answer: B

Rationale: The correct answer is to draw up the cloudy insulin as ordered. NPH insulin is inherently cloudy due to its suspension of insulin crystals. Shaking the vial vigorously can lead to denaturation of the insulin molecules, altering its efficacy. Warming NPH insulin is not necessary as it can cause breakdown of insulin molecules. The nurse should gently roll the vial between hands to mix it before drawing it up to ensure an even distribution of insulin in the suspension.

3. A client newly diagnosed with DM asks a nurse why it is necessary to monitor blood glucose levels so often. The nurse's best response would be:

• A. It helps to adjust insulin doses more precisely.
• B. It helps to prevent complications of diabetes.
• C. It helps to identify the best diet for you.
• D. It helps to reduce the need for medications.

Correct answer: B

Rationale: Monitoring blood glucose levels frequently is crucial for preventing complications in diabetes. By keeping a close eye on blood glucose levels, healthcare providers can intervene in a timely manner if levels are out of range, thus reducing the risk of long-term complications such as nerve damage, kidney disease, and vision problems. Choices A, C, and D are incorrect because while monitoring blood glucose levels may indirectly contribute to adjusting insulin doses, identifying the best diet, and reducing the need for medications, the primary purpose is to prevent complications through timely interventions.

4. Why is glucose an important molecule in a cell?

• A. Extraction of energy
• B. Synthesis of protein
• C. Building of genetic material
• D. Formation of cell membranes

Correct answer: A

Rationale: Glucose is a crucial molecule in cells because it serves as the primary source of energy through cellular respiration. Choice B, the synthesis of protein, is incorrect because proteins are typically synthesized from amino acids, not glucose. Choice C, the building of genetic material, is incorrect because genetic material, such as DNA and RNA, is not directly built from glucose. Choice D, the formation of cell membranes, is also incorrect as cell membranes are primarily composed of lipids and proteins, not glucose.

5. The nurse is caring for a client with hyperparathyroidism. Which of the following clinical manifestations is consistent with this condition?

• A. Hypocalcemia
• B. Hypercalcemia
• C. Hypokalemia
• D. Hyperphosphatemia

Correct answer: B

Rationale: In hyperparathyroidism, there is an overproduction of parathyroid hormone, leading to increased calcium levels in the blood (hypercalcemia). This occurs as the parathyroid hormone stimulates the release of calcium from the bones and enhances calcium absorption in the intestines and kidneys. Therefore, the correct answer is hypercalcemia (Choice B). Hypocalcemia (Choice A) is not consistent with hyperparathyroidism, as this condition is characterized by high calcium levels. Hypokalemia (Choice C) and hyperphosphatemia (Choice D) are not typically associated with hyperparathyroidism and are not primary manifestations of this condition.
