A nurse in a PACU is admitting a client who is postoperative following a tonsillectomy. Which actions should the nurse plan to take to prevent aspiration?

A. A humidifier can help keep secretions moist and reduce discomfort, but it does not prevent aspiration and is not a priority in the immediate postoperative period. B. Suctioning the nasopharynx should be done with caution after a tonsillectomy, as it can irritate the surgical site and cause bleeding; it is not a routine action to prevent aspiration. C. Chest physiotherapy is not appropriate in the immediate postoperative period following a tonsillectomy and could increase the risk of bleeding. D. After a tonsillectomy, the nurse should withhold oral fluids until the child is fully awake and has a demonstrated gag reflex, which helps ensure that the airway is protected and reduces the risk of aspiration.
