Final answer:
When a child on a ventilator exhibits signs of poor oxygenation, the nurse should check the endotracheal tube placement, assess if there is any obstruction, and examine the ventilator equipment for correct connection.
Step-by-step explanation:
When a nurse observes signs of poor oxygenation in a child who is connected to a ventilator with an endotracheal tube, there are several things they should do to assess the situation. These include:
- Assess tracheal tube placement: The nurse should check if the endotracheal tube is properly positioned in the child's trachea.
- Assess for tracheal tube obstruction: The nurse should ensure that the endotracheal tube is not obstructed, as this can interfere with proper oxygenation.
- Assess the ventilator equipment: The nurse should examine the ventilator equipment to make sure all tubing is connected correctly, as any disconnection can affect oxygenation.
