The LPN/LVN is suctioning a patient through an endotracheal tube. What indicates proper technique? (Select all that apply.)

1. Preoxygenating the patient before suctioning
2. Dipping the suction catheter into sterile saline before suctioning
3. Using a clean catheter with each suctioning attempt
4. Withdrawing the catheter with the thumb continually covering the suction control vent
5. Suctioning the tube for at least 30 seconds with each suctioning attempt

Answer :

Final answer:

Proper technique for suctioning an endotracheal tube involves oxygenating the patient, dipping the catheter into sterile saline, and using a clean catheter with each attempt. Over-suctioning and continuously covering the suction control vent are not correct techniques.

Explanation:

When suctioning a patient through an endotracheal tube, the correct technique is critical to ensure patient safety and the effectiveness of the treatment. The methods listed in the question that indicate proper technique include:

  1. Preoxygenating the patient before suctioning - This ensures adequate oxygenation during the procedure, which can momentarily interfere with normal respiration.
  2. Dipping the suction catheter into sterile saline before suctioning - This helps to lubricate the catheter, making the procedure smoother and less irritating for the patient. It also helps remove mucus from the catheter.
  3. Using a clean catheter with each suctioning attempt - This is crucial to prevent cross-contamination and infection.

The point about Withdrawing the catheter with the thumb continually covering the suction control vent is incorrect. The thumb should be removed from the vent to apply suction on withdrawal. Also, the point about Suctioning the tube for at least 30 seconds with each suctioning attempt is incorrect; this could cause hypoxia. Suction should be applied for no more than 10-15 seconds.
