Nursing Elites

1. The nurse is caring for a client with a central venous catheter. What is the most important action for the nurse to take to prevent infection?

• A. Change the catheter dressing every 72 hours.
• B. Flush the catheter with heparin solution daily.
• C. Ensure the catheter is clamped when not in use.
• D. Maintain sterile technique when handling the catheter.

Correct answer: D

Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. Changing the catheter dressing every 72 hours, while important for overall catheter care, does not directly address infection prevention. Flushing the catheter with heparin solution daily is essential for maintaining patency but does not primarily prevent infections. Ensuring the catheter is clamped when not in use is important for preventing air embolism but is not the most critical action to prevent infection. The most effective way to prevent infections is by strictly adhering to sterile techniques during catheter handling, which minimizes the risk of introducing pathogens into the catheter site.

2. A mother of a child with a neural tube defect asks the nurse what she can do to decrease the chances of having another baby with a neural tube defect. What is the best response by the nurse?

• A. Folic acid should be taken before and after conception.
• B. Multivitamin supplements are recommended during pregnancy.
• C. A well-balanced diet promotes normal fetal development.
• D. Increased dietary iron improves the health of mother and fetus.

Correct answer: A

Rationale: The correct answer is A: 'Folic acid should be taken before and after conception.' Folic acid supplementation before and during early pregnancy has been shown to significantly reduce the risk of neural tube defects. Choice B is incorrect because while multivitamin supplements are beneficial during pregnancy, the specific focus for preventing neural tube defects is on folic acid. Choice C is a general statement about a well-balanced diet and does not specifically address neural tube defects. Choice D is incorrect as it focuses on dietary iron, which is important for overall health but not specifically proven to prevent neural tube defects.

3. A client has a closed wound drainage system. Which of the following actions should the nurse take?

• A. Avoid pressing the container down to create a vacuum
• B. Wear sterile gloves while handling the drainage system
• C. Reset the container with the drainage port closed
• D. Maintain the drain in a dependent position to facilitate drainage

Correct answer: D

Rationale: In a closed wound drainage system, it is essential to maintain the drain in a dependent position to allow for proper drainage. Gravity aids in the flow of drainage, preventing fluid backflow or pooling. Avoiding pressing the container down to create a vacuum (Choice A) is crucial as it can lead to complications in the system. Wearing sterile gloves (Choice B) is important for infection control when handling the drainage system. Resetting the container with the drainage port closed (Choice C) is incorrect as it can cause spillage and contamination of the surrounding area.

4. What action should the LPN/LVN take to prevent postoperative complications in a client who has undergone abdominal surgery?

• A. Encourage the client to use an incentive spirometer regularly.
• B. Assist the client in ambulating as soon as possible.
• C. Position the client in high Fowler's position.
• D. Encourage the client to cough and deep breathe regularly.

Correct answer: A

Rationale: Encouraging the client to use an incentive spirometer regularly is crucial in preventing postoperative complications after abdominal surgery. This action helps prevent atelectasis by promoting lung expansion and improving air exchange in the lungs, reducing the risk of respiratory complications. Assisting the client in ambulating early is important for preventing issues like deep vein thrombosis but may not directly address respiratory concerns postoperatively. Positioning the client in high Fowler's position can help with respiratory distress but is not as specific to preventing postoperative respiratory complications as using an incentive spirometer. While encouraging the client to cough and deep breathe is generally beneficial for lung expansion, using an incentive spirometer is more effective and targeted in preventing atelectasis after abdominal surgery.

5. When caring for a client receiving warfarin sodium (Coumadin), which lab test would the nurse monitor to determine therapeutic response to the drug?

• A. Bleeding time
• B. Coagulation time
• C. Prothrombin time
• D. Partial thromboplastin time

Correct answer: C

Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.
