Difficulty: MediumPharmacological and Parenteral Therapies

A nurse is preparing to remove a non-tunneled central venous catheter (CVC) from a client's internal jugular vein. Place the following nursing actions in the correct chronological order to ensure client safety and prevent complications during the procedure.

  1. 1Place the client in a supine or slight Trendelenburg position.
  2. 2Remove the transparent dressing and any securement devices.
  3. 3Instruct the client to take a deep breath and bear down (Valsalva maneuver).
  4. 4Withdraw the catheter smoothly and continuously.
  5. 5Apply immediate, firm pressure to the insertion site using sterile gauze.
  6. 6Inspect the distal tip of the removed catheter to verify it is intact.

Answer

The correct sequence for removing a central venous catheter is to position the client supine, remove the dressing, instruct the client to bear down, withdraw the catheter, apply firm pressure, and finally inspect the catheter tip.
The safe removal of a central venous catheter prioritizes the prevention of an air embolism. The procedure begins by placing the client flat or in a slight Trendelenburg position to increase central venous pressure. After removing the dressing to free the catheter, the nurse instructs the client to bear down (Valsalva maneuver) to elevate intrathoracic pressure. The catheter is withdrawn exactly during this maneuver to ensure the vein remains under positive pressure. Immediate manual pressure is then applied to the site to achieve hemostasis and form an airtight seal over the tract. Finally, the nurse inspects the catheter tip to ensure no fragments were retained in the patient.

Step-by-Step Solution

1
Place the client in a supine or slight Trendelenburg position.
Central venous pressure is increased.
This positioning prevents an air embolism by keeping the venous pressure higher than atmospheric pressure.
2
Remove the transparent dressing and any securement devices.
The catheter is freed from the skin.
The site must be fully prepared before the client is instructed to alter their breathing pattern.
3
Instruct the client to take a deep breath and bear down.
Intrathoracic pressure is temporarily increased.
The Valsalva maneuver ensures positive pressure in the vein, further protecting against air entry.
4
Withdraw the catheter smoothly and continuously.
The catheter is completely removed from the jugular vein.
Removing the line while the client bears down minimizes the time the open tract is exposed to potential air intake.
5
Apply immediate, firm pressure to the insertion site using sterile gauze.
Hemostasis is achieved and the entry tract is sealed.
Firm pressure prevents bleeding and physically blocks air from entering the vein.
6
Inspect the distal tip of the removed catheter.
The physical integrity of the catheter is confirmed.
This verification ensures no pieces of the catheter have broken off into the client's bloodstream.

Key Concept

Safe removal of a central venous catheter requires strict adherence to procedural steps that prevent air embolism, primarily through patient positioning and the utilization of the Valsalva maneuver.
