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?

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.

The APN, also known as a nurse practitioner or clinical nurse specialist, has advanced knowledge and expertise in pharmacology and medication management. They are trained to assess medication interactions, evaluate potential risks, and provide guidance to ensure safe and effective medication use.

The other members of the interdisciplinary team listed are not specifically trained to address medication interactions:

Social workers focus on addressing psychosocial aspects of care, such as emotional support, counseling, and resource coordination. While they may provide valuable assistance in various areas of the client's care, they typically do not have specialized knowledge in medication interactions.

Patient care technicians, also known as nursing assistants or certified nursing assistants, provide direct patient care under the supervision of nurses. They do not typically have the training or authority to address medication interactions.

Psychologists specialize in the assessment, diagnosis, and treatment of mental and emotional health concerns. While they may be involved in the client's overall care, including medication management for mental health conditions, their expertise lies primarily in psychological assessment and therapy rather than medication interactions.
