A nurse is reinforcing teaching with a client who has a urinary tract infection.

Which of the following instructions should the nurse include in the teaching?

Fontanels are soft spots on an infant's skull where the bones have not yet fused together. The anterior fontanel, located at the front of the head, typically closes between 12 to 18 months of age. The posterior fontanel, located at the back of the head, usually closes by 2 to 3 months of age.
The other findings mentioned are typical developmental milestones for a 4-month-old infant:
1. Rolling from back to abdomen: By 4 months of age, it is expected that infants can roll from their back to their abdomen. This is a normal developmental milestone.
2. Moves objects to mouth: At 4 months, infants begin to develop hand-eye coordination and the ability to reach for objects. Bringing objects to the mouth is a typical behavior at this age as infants explore their environment.

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:
A. 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.
C. Using a clean technique when changing the catheter dressing is not appropriate for CVC insertion. A sterile technique is required during the insertion of a CVC to minimize the risk of infection.
D. 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.
