Which reflex is used to help determine when to remove the endotracheal tube?

• A. Pedal reflex
• B. Anal reflex
• C. Laryngeal reflex
• D. Palpebral reflex

Answer: (C)

Protecting the airway is what matters when deciding to remove the endotracheal tube. The laryngeal reflex specifically reflects airway protection because it governs the cough response to laryngeal stimulation. A functional laryngeal reflex means the patient can cough and clear secretions, helping prevent aspiration after extubation. Pedal reflex is a limb withdrawal reflex, not related to airway protection. Anal reflex relates to sacral spinal function, and the palpebral reflex (blink in response to stimulus near the eye) indicates brainstem activity but not airway protection.
