Final answer:
The appropriate intervention for a client who has undergone a total laryngectomy is the use of a tracheostomy tube.
Step-by-step explanation:
The appropriate intervention for a client who has undergone a total laryngectomy as part of the immediate postoperative care plan is the use of a tracheostomy tube.
During a total laryngectomy, the larynx (voice box) is removed, which affects the client's ability to breathe and speak normally. Placing a tracheostomy tube into the trachea allows for a secure airway and assists with breathing.
This intervention ensures that the client can maintain a patent airway and protects the surgical site from aspiration.
