A nurse is caring for a client who is receiving mechanical ventilation via an endotracheal tube. Which of the following actions should the nurse take?

Performing oral care every 2 hours is an important nursing intervention for a client receiving mechanical ventilation via an endotracheal tube. This helps to reduce the risk of ventilator-associated pneumonia. a) Monitoring the client's vital signs is important, but it should be done more frequently than every 8 hours. b) Repositioning the endotracheal tube is not necessary unless there is a specific indication. c) Placing the client in a supine position is not recommended as it increases the risk of aspiration.
