A nurse is caring for a client who has an endotracheal tube (ET) and is on mechanical ventilation. Which of the following actions should the nurse take for a ventilator alarm due to an increase in peak airway pressure? (Select all that apply.)

An increase in peak airway pressure indicates increased resistance or obstruction. Suctioning removes secretions that increase resistance. Checking for kinks in the tubing identifies physical obstructions. Verifying ET placement ensures the tube has not migrated or caused a pneumothorax. A cuff leak would cause a low-pressure alarm, not a high-pressure alarm. Disconnection of tubing would also cause a low-pressure alarm.
