A practical nurse enters the room of a client who has a central venous catheter. The nurse discovers that the intravenous tubing has disconnected from the catheter hub. The client suddenly reports sharp chest pain, is gasping for air, and appears cyanotic. In what order should the nurse perform the following actions to reduce the client's risk of further harm? Arrange the steps in the correct sequence from first to last.
- 1Clamp the central venous catheter.
- 2Place the client in a left lateral Trendelenburg position.
- 3Administer high-flow oxygen via a non-rebreather mask.
- 4Activate the Rapid Response Team and notify the registered nurse.
- 5Obtain a complete set of vital signs.
Cevap
The correct sequence for managing a suspected central line air embolism is to first clamp the catheter to stop air entry, then position the client in a left lateral Trendelenburg position to trap the air, followed by administering high-flow oxygen, activating the Rapid Response Team, and finally obtaining vital signs.
The sequence reflects the fundamental principles of risk reduction during an acute central line complication: stop the source of the injury (clamp), mitigate the immediate pathophysiological risk (position to trap air), treat the physiological symptoms (oxygen), escalate care (call for help), and evaluate the client's status (vital signs).
Adım Adım Çözüm
Anahtar Kavram
Prioritization of interventions for a central venous catheter air embolism requires stopping the source of air first, followed by mechanical positioning to trap the air, and then supportive oxygen therapy.
