A client who has had a laryngectomy and tracheostomy frequently expectorates copious amounts of purulent secretions. When changing the ties of the tracheostomy tube, which action is most important for the nurse to take?

Remove ties to secure a disposable, soft foam collar with hook and loop fastener.

Leave the old tube in place until the new ones are secure.

Place knots of the ties laterally to prevent irritation and pressure.

Secure tracheostomy ties by making knots close to the tube.
