a. Non-rebreather mask
b. Bag-valve-mask unit
c. Continuous positive airway pressure (CPAP)
d. High-flow nasal cannula
ANS: B
The priority of the nurse is to ventilate the patient manually using an Ambu bag-valve-mask unit. This allows air to be forced into the patient's lungs when there are no spontaneous respirations. The non-rebreather mask and nasal cannula require the patient to breathe on his own. CPAP is used for patients who are awake, oriented, and in respiratory failure.
