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

Secure tracheostomy ties by making knots close to the tube.

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

Remove ties to secure a disposable, soft foam collar with self-adhesive fastening.

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