A nurse is caring for a client who had a total laryngectomy. Which finding requires the MOST urgent intervention?

TOTAL LARYNGECTOMY creates a PERMANENT STOMA (opening) in the anterior neck as the client's ONLY airway — the trachea is no longer connected to the mouth and nose.

Critical concept: A standard bag-valve-mask over the face does NOT ventilate a laryngectomy patient — the mouth and nose are disconnected from the trachea; resuscitation must be done through the STOMA.

Airway emergency signs: Decreasing SpO₂; absent or diminished breath sounds on auscultation at the stoma; audible stridor; increased respiratory effort; cyanosis; patient distress.

Causes of stoma obstruction: Mucus plug (most common — humidified air and suctioning prevent this); blood clot; stoma stenosis; equipment issues.

Nursing priorities: CALL FOR HELP immediately; suction the stoma first (often clears a mucus obstruction); if suctioning doesn't relieve the obstruction, notify the provider/surgical team stat; maintain humidity (humidified air prevents mucus plugging — dry air is the enemy of laryngectomy patients); have stoma covers/bibs available; teach the patient SELF-CARE: how to suction, clean, and cover the stoma.

Emergency response: BVM must be applied to the STOMA, not the face, for resuscitation; all first responders must know the patient has a laryngectomy (medic alert bracelet, 'Neck Breather' notification); some patients choose to post a note at their bedside.
