Answer :
The nurse caring for a client with pulmonary edema should assess for conditions such as a biting endotracheal tube, endotracheal tube cuff leak, and kinked ventilator tubing, as these can trigger the high-pressure alarm on the mechanical ventilator. The correct answers are 1. Biting endotracheal tube, 3. Endotracheal tube cuff leak, and 5. Kinked ventilator tubing.
Biting endotracheal tube: If the client is biting down on the endotracheal tube, it can cause obstruction of airflow, leading to increased pressure in the ventilator circuit and triggering the high-pressure alarm.
Endotracheal tube cuff leak: A leak in the cuff of the endotracheal tube can allow air to escape, resulting in inadequate sealing of the airway and loss of positive pressure ventilation. This can lead to increased airway resistance and trigger the high-pressure alarm on the ventilator.
Kinked ventilator tubing: If the ventilator tubing becomes kinked or compressed, it can obstruct the flow of air, resulting in increased pressure within the ventilator circuit. This can trigger the high-pressure alarm as the ventilator tries to overcome the obstruction.
The correct answers are 1. Biting endotracheal tube, 3. Endotracheal tube cuff leak, and 5. Kinked ventilator tubing.
