Answer - B - An unsecured tracheal tube that has slid down inside the trachea can stimulate parasympathetic receptors located near and on the carina. Once activated, these receptors can precipitate bradycardia and hypotension. Securing a tracheal tube does little in terms of preventing a patient from biting down on the tube so a bite block or oropharyngeal airway could be employed.
