Nursing Elites

1. 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.

2. What is the correct method of administering insulin to a patient with diabetes?

• A. Administer subcutaneously
• B. Administer intramuscularly
• C. Administer intravenously
• D. Administer orally

Correct answer: A

Rationale: The correct method of administering insulin to a patient with diabetes is to administer it subcutaneously. Insulin is typically injected into the fatty tissue just below the skin, allowing for a slow and consistent absorption into the bloodstream. Administering insulin intramuscularly (Choice B) is not recommended as it can lead to unpredictable absorption rates and potential complications. Administering insulin intravenously (Choice C) is only done in specific medical settings and not for routine diabetes management. Administering insulin orally (Choice D) is ineffective as the stomach acid would break down the insulin before it can be absorbed.

3. What is the priority nursing intervention for a patient experiencing an acute asthma attack?

• A. Administer bronchodilators
• B. Monitor oxygen saturation
• C. Provide supplemental oxygen
• D. Start IV fluids

Correct answer: A

Rationale: The correct answer is to administer bronchodilators. In an acute asthma attack, the priority is to open the airways and improve airflow. Bronchodilators like albuterol are crucial in providing immediate relief to the patient. Monitoring oxygen saturation (choice B) is important but administering bronchodilators takes precedence in managing the acute attack. Providing supplemental oxygen (choice C) may be necessary but addressing the airway obstruction with bronchodilators is the priority. Starting IV fluids (choice D) is not the priority in an acute asthma attack unless specifically indicated for other reasons such as dehydration.

4. A nurse is preparing to administer dopamine hydrochloride 4 mcg/kg/min via continuous infusion. The client weighs 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?

• A. 6 mL/hr
• B. 8 mL/hr
• C. 12 mL/hr
• D. 16 mL/hr

Correct answer: A

Rationale: To calculate the correct rate, use the formula: (4 mcg/kg/min * 80 kg) / 800 mcg in 250 mL = 6 mL/hr. This calculation is based on the dose ordered (4 mcg/kg/min) multiplied by the patient's weight in kg (80 kg), divided by the concentration of the drug available (800 mcg in 250 mL) to be infused over 1 hour. Therefore, the correct answer is 6 mL/hr. Choices B, C, and D are incorrect as they do not reflect the accurate calculation based on the provided information.

5. 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.
