Choice A rationale:

This statement is correct. The client should inform the nurse if they notice any food particles in their tracheal secretions as it could indicate aspiration and require immediate attention.

Choice B rationale:

This statement indicates a need for further education. A larger tracheostomy tube to prevent an air leak at the stoma is not an appropriate intervention for tracheomalacia. Tracheomalacia is the weakening of the tracheal cartilage, and a larger tube would not address this underlying issue.

Choice C rationale:

This statement is also incorrect. Minimizing the time the cuff is inflated may be beneficial to prevent tracheal stenosis but would not prevent tracheomalacia, which is a different condition altogether.

Choice D rationale:

This statement is correct. Monitoring cuff pressure and air volumes closely is essential to prevent complications and ensure appropriate cuff inflation.
