Nursing Elites

1. 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.

2. A client who is at 36 weeks of gestation is scheduled for a nonstress test. Which of the following client statements 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 takes about 10 minutes and evaluates fetal heart rate in response to fetal movement. Choice A is incorrect because fasting is not required for a nonstress test. Choice C is incorrect as a full bladder is not necessary for this test. Choice D is incorrect as blood glucose checking is not typically part of a nonstress test.

3. Which lab value should be monitored in a patient on digoxin?

• A. Monitor potassium levels
• B. Monitor calcium levels
• C. Monitor digoxin levels
• D. Monitor sodium levels

Correct answer: C

Rationale: The correct answer is to monitor digoxin levels in a patient on digoxin. Digoxin is a medication commonly used to treat heart conditions, and monitoring its levels in the blood is crucial to ensure that the patient is within the therapeutic range and to prevent toxicity. Monitoring potassium levels (Choice A) is important due to the potential of digoxin-induced hypokalemia, but the primary focus should be on monitoring digoxin levels. Monitoring calcium levels (Choice B) and sodium levels (Choice D) are not directly related to digoxin therapy and are not the primary lab values of concern when administering digoxin.

4. A nurse is caring for a client who is postoperative following a total knee arthroplasty. Which of the following interventions should the nurse include in the plan of care?

• A. Apply heat to the incision site.
• B. Keep the client's knee flexed while in bed.
• C. Place a pillow under the client's knee while in bed.
• D. Place a pillow under the client's lower legs.

Correct answer: D

Rationale: Placing a pillow under the client's lower legs is the correct intervention because it helps prevent pressure on the incision site and promotes circulation. Elevating the lower legs also aids in reducing swelling and improving blood flow. Applying heat to the incision site (Choice A) is contraindicated in the early postoperative period as it can increase inflammation and the risk of infection. Keeping the client's knee flexed while in bed (Choice B) may lead to contractures or limited extension of the knee joint. Placing a pillow under the client's knee (Choice C) may cause hyperextension of the knee, which is also not recommended post knee arthroplasty.

5. A healthcare professional is preparing to administer an intermittent enteral feeding to a client who has an NG tube. Which of the following actions should the healthcare professional take first?

• A. Check the residual volume.
• B. Flush the tube with 0.9% sodium chloride.
• C. Elevate the head of the bed to 45 degrees.
• D. Warm the formula to body temperature.

Correct answer: C

Rationale: Elevating the head of the bed to 45 degrees is the priority action before administering an enteral feeding through an NG tube. This position helps prevent aspiration by promoting proper flow and digestion of the feeding. Checking the residual volume, flushing the tube, and warming the formula are important steps but come after ensuring the client is in the correct position to minimize the risk of complications.
