A nurse is reinforcing dietary teaching with a client who has constipation about appropriate food choices. Which of the following food selections by the client demonstrates an understanding of the teaching?

Deep-vein thrombosis (DVT) is a condition where a blood clot forms in a deep vein, usually in the legs. Bed rest is often recommended for clients with DVT to reduce the risk of the clot dislodging and causing a pulmonary embolism. By minimizing movement and keeping the leg elevated, the nurse can help prevent further complications.

The other options listed are incorrect:

1. Massage the affected extremity every 4 hours: Massaging the affected extremity can dislodge the clot, increasing the risk of a pulmonary embolism. It is contraindicated and should not be performed in clients with DVT.
2. Apply an ice pack to the affected extremity for 20 minutes every 2 hours: While applying cold compresses or ice packs may be useful in some situations to reduce swelling or pain, it is not recommended for clients with DVT. Heat application or cold application should be avoided because they can promote blood circulation and potentially dislodge the clot.
3. Administer aspirin for pain: Aspirin is not typically used for pain management in DVT. Anticoagulant therapy is the primary treatment for DVT, and specific anticoagulant medications are prescribed to prevent further clot formation and reduce the risk of complications.

When a central venous catheter (CVC) is inserted, it is essential to confirm proper catheter placement to ensure safe and effective administration of TPN and other medications. A chest x-ray is the gold standard method to verify the correct positioning of the CVC tip. It helps determine if the catheter is appropriately positioned in the superior vena cava or another desired location, which minimizes the risk of complications such as pneumothorax or improper medication delivery.

The other options listed are not appropriate actions for the nurse to take in this situation:

1. Verifying the amount of TPN solution the client is receiving every 4 hours is a task related to ongoing monitoring of TPN administration, but it is not directly related to the preparation of the client for CVC insertion.
2. Using clean technique when changing the catheter dressing is not appropriate for CVC insertion. Sterile technique is required during the insertion of a CVC to minimize the risk of infection.
3. Placing the client in Sims' position is not the appropriate position for CVC insertion. The client is typically placed in a supine or Trendelenburg position during the procedure to facilitate access to the central venous system.
