What is the primary concern for a nurse caring for a client with a new central venous catheter?

The primary concern for a nurse caring for a client with a new central venous catheter is catheter patency. Maintaining catheter patency is crucial because it ensures that the catheter remains unobstructed, allowing for the efficient administration of medications, fluids, and nutrition directly into the central circulation. A blocked catheter can lead to complications such as increased risk of infection, thrombus formation, or the inability to provide necessary treatments. Regular checks for patency, proper flushing techniques, and timely interventions for any signs of blockage are essential components of nursing care in this scenario. By prioritizing catheter patency, the nurse can help prevent complications and ensure optimal patient outcomes.
