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. Which electrolyte imbalance is most concerning in a patient on furosemide?

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

Correct answer: B

Rationale: The correct answer is Hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion by increasing its excretion in the urine. Hypokalemia is a common and concerning side effect of furosemide therapy. Hyperkalemia (Choice A) is less likely as furosemide tends to lower potassium levels. Hyponatremia (Choice C) is more commonly seen with thiazide diuretics. Hypercalcemia (Choice D) is not directly associated with furosemide use.

3. A client sustained a major burn over 20% of the body. What intervention should the nurse implement to meet the client's nutritional needs?

• A. Keep track of calorie intake for food and beverages.
• B. Provide a low-protein, high-carbohydrate diet.
• C. Schedule meals at 6-hour intervals.
• D. Provide a high-protein, high-calorie diet.

Correct answer: D

Rationale: The correct answer is to provide a high-protein, high-calorie diet for a client with major burns. This type of diet is essential to support healing and recovery. High-protein intake is crucial as it helps in tissue repair and wound healing, while high-calorie intake is necessary to meet the increased metabolic demands of the body during the healing process. Keeping track of calorie intake (Choice A) is important but doesn't address the specific needs of a burn patient. Providing a low-protein, high-carbohydrate diet (Choice B) is not suitable for burn patients as they require adequate protein for wound healing. Scheduling meals at 6-hour intervals (Choice C) may be helpful for maintaining a consistent eating schedule, but it is not as crucial as providing the correct high-protein, high-calorie diet.

4. A client has a central venous catheter. Which of the following actions should be taken to prevent an air embolism?

• A. Keep the catheter clamped when not in use
• B. Have the client perform the Valsalva maneuver while the catheter is removed
• C. Use a non-coring needle to access the catheter
• D. Flush the catheter with 0.9% sodium chloride every 24 hours

Correct answer: B

Rationale: The correct action to prevent an air embolism in a client with a central venous catheter is to have the client perform the Valsalva maneuver while the catheter is removed. This maneuver helps to close the airway and prevent air from entering the bloodstream. Keeping the catheter clamped at all times (Choice A) is not necessary and may lead to clot formation. Using a non-coring needle (Choice C) is important for accessing the catheter but does not specifically prevent air embolism. Flushing the catheter with 0.9% sodium chloride (Choice D) helps maintain patency but does not directly prevent air embolism.

5. A client who is at 36 weeks of gestation is scheduled for a nonstress test (NST). Which of the following statements by the client indicates an understanding of the teaching?

• A. I should fast for 12 hours before the test.
• B. I should expect the test to take about 10 minutes.
• C. I should have a full bladder for this test.
• D. I will need to have my blood glucose checked before the test.

Correct answer: B

Rationale: The correct answer is B. The nonstress test typically takes about 10 minutes and evaluates the fetal heart rate in response to fetal movement. Having a full bladder or fasting for 12 hours is not required for a nonstress test. Checking blood glucose levels is not part of the nonstress test procedure.
