A nurse at a long-term care facility is reinforcing teaching with a newly hired nurse about care of clients who are receiving mechanical ventilation. Which of the following information should the nurse include?

A. Turn off the ventilator alarms before suctioning the client's airway: Ventilator alarms should never be turned off because they alert staff to changes in airway pressure, disconnection, or other critical issues. B. Place the head of the client's bed at 40° when supine: Elevating the head of the bed to 30–45° helps reduce the risk of aspiration and ventilator-associated pneumonia in mechanically ventilated clients. C. Reposition the client every 4 hr: Clients on mechanical ventilation should be repositioned more frequently, typically every 2 hours, to prevent pressure injuries and improve lung expansion. Waiting 4 hours may increase the risk of complications such as skin breakdown and atelectasis. D. Provide mouth care every 10 to 12 hr with hydrogen peroxide: Oral care should be provided at least every 2–4 hours with appropriate antiseptic solutions (e.g., chlorhexidine) rather than hydrogen peroxide every 10–12 hours.
