The nurse uses a closed-system endotracheal (ET) suctioning system for the client. Which does the nurse implement?

Question

1. Insert catheter between ventilator cycles to avoid airway interference.
2. Insert catheter 10 inches and apply continuous suction during withdrawal.
3. Visualize black line in the catheter's sheath before completing procedure.
4. Withdraw suction and discard suction catheter after completing procedure.

Answer 1

3. The nurse visualizes the catheter's black line after withdrawing the suction catheter from the ET because the black line indicates that the catheter is completely removed from the airway.
1. The nurse inserts the catheter from suctioning during client inhalation to avoid respiratory cycle interference for suctioning.
2. The nurse inserts the catheter until resistance is met to avoid suctioning in the main left or right bronchi.
4. The closed-system suctioning system allows the nurse to use the same catheter for repeated client suctioning by using sterile technique.
