A 23-year-old male experienced severe head trauma after his motorcycle collided with an oncoming truck. He is unconscious, has rapid and shallow breathing, and has copious bloody secretions in his mouth. How should you manage his airway? Select one: a. Insert a nasopharyngeal airway and provide suction and assisted ventilations. b. Provide continuous ventilations with a bag-valve mask to minimize hypoxia. c. Alternate 15 seconds of oral suctioning with 2 minutes of assisted ventilation. d. Suction his oropharynx with a rigid catheter until all secretions are removed.

c. Alternate 15 seconds of oral suctioning with 2 minutes of assisted ventilation.

To select the proper size oropharyngeal airway, you should measure from the: Select one: a. comer of the mouth to the superior ear. b. angle of the jaw to the center of the mouth. c. corner of the mouth to the earlobe. d. center of the mouth to the posterior ear.

c. corner of the mouth to the earlobe.

The MOST significant complication associated with orophaiyngeal suctioning is: Select one: a. vomiting from stimulating the anterior airway. b. clogging of the catheter with thick secretions. c. hypoxia due to prolonged suction attempts. d. oral abrasions from vigorous suctioning.

c. hypoxia due to prolonged suction attempts.

Complications associated with using a manually triggered ventilation device include: Select one: a. inadequate oxygenation and tracheal injury. b. inadequate ventilation and hypercarbia. c. lung tissue injury and gastric distention. d. reduced tidal volume delivery and hypoxia.
