Nursing Elites

1. What is the primary purpose of administering insulin to a patient with diabetes?

• A. Regulate blood glucose levels
• B. Increase metabolism
• C. Prevent complications
• D. Promote insulin sensitivity

Correct answer: A

Rationale: The correct answer is A: 'Regulate blood glucose levels.' Administering insulin to a patient with diabetes helps regulate blood glucose levels by facilitating the uptake of glucose into cells, thereby lowering high blood sugar levels. This process aims to prevent hyperglycemia and its associated complications. Choice B, 'Increase metabolism,' is incorrect as the primary role of insulin is not to increase metabolism directly. Choice C, 'Prevent complications,' is partially correct as regulating blood glucose through insulin administration does help prevent complications associated with uncontrolled diabetes, but it is not the primary purpose. Choice D, 'Promote insulin sensitivity,' is incorrect as insulin itself is administered to compensate for the lack of endogenous insulin in diabetic patients, rather than to promote sensitivity to it.

2. What is the priority nursing intervention for a patient with hyperkalemia?

• A. Administer calcium gluconate
• B. Administer insulin
• C. Administer sodium bicarbonate
• D. Administer a diuretic

Correct answer: A

Rationale: The correct answer is to administer calcium gluconate. In hyperkalemia, the priority is to protect the heart from potential complications like arrhythmias. Calcium gluconate is the first-line treatment as it stabilizes the cardiac cell membrane. Insulin (Choice B) and sodium bicarbonate (Choice C) can be used in conjunction with other treatments to shift potassium into cells, but calcium gluconate is the priority. Administering a diuretic (Choice D) is not the primary intervention for hyperkalemia and can even worsen the condition by reducing potassium excretion.

3. Which electrolyte imbalance is commonly seen in patients taking furosemide?

• A. Hypokalemia
• B. Hyponatremia
• C. Hyperkalemia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss in the urine, resulting in hypokalemia. This electrolyte imbalance is commonly seen in patients taking furosemide and requires close monitoring. Choices B, C, and D are incorrect because furosemide does not typically cause hyponatremia, hyperkalemia, or hypercalcemia as frequently as it causes hypokalemia.

4. A nurse is caring for a client who is postoperative following a total knee arthroplasty. Which of the following actions should the nurse take?

• A. Place a pillow under the client's knees
• B. Keep the client's legs elevated
• C. Flex the client's knee every 2 hours
• D. Apply heat to the operative knee

Correct answer: B

Rationale: Keeping the client's legs elevated is the appropriate action to prevent venous thromboembolism following a total knee arthroplasty. Elevating the legs helps promote circulation and reduce the risk of blood clots. Placing a pillow under the client's knees may provide comfort but does not address the specific postoperative complication. Flexing the client's knee every 2 hours may be contraindicated as excessive movement can disrupt the surgical site. Applying heat to the operative knee is not recommended immediately postoperatively as it can increase swelling and discomfort.

5. A client with a new colostomy requires care planning by a nurse. Which of the following interventions should the nurse include in the plan of care?

• A. Change the ostomy pouch every 4 to 7 days.
• B. Empty the ostomy pouch when it is half full.
• C. Apply a skin barrier around the stoma.
• D. Cleanse the peristomal skin with alcohol.

Correct answer: A

Rationale: The correct answer is to change the ostomy pouch every 4 to 7 days. This practice helps prevent skin irritation and leakage by maintaining a clean and secure seal around the stoma. Option B is incorrect because it is more important to change the pouch regularly rather than emptying it when half full. Option C is incorrect as applying a skin barrier is typically done during the initial application of the pouch, not during regular changes. Option D is incorrect because alcohol can be too harsh for the peristomal skin and can cause irritation.
