NR325 Adult Health II ME Practice Test

Open tracheal suctioning begins with establishing sterile technique because the airway is normally sterile and the catheter enters the trachea, creating a direct pathway for any contaminants. Using sterile gloves and a sterile suction catheter helps prevent introducing bacteria into the lower airway, reducing the risk of infection such as ventilator-associated pneumonia. Once asepsis is secured, preoxygenation as indicated helps protect against hypoxemia during the procedure, and suctioning is performed during withdrawal rather than insertion. Monitoring heart rate and oxygen saturation is continuous during the procedure to catch any adverse responses.
