A 51-year-old female was just removed from a house fire.

The correct answer is C because this patient is showing signs of respiratory failure , including a respiratory rate of 8 (too slow) , shallow breathing , cyanosis , and altered mental status .

NREMT-aligned airway and breathing guidelines state that patients with inadequate respirations require positive pressure ventilation with a bag-valve mask (BVM) . Simply increasing oxygen or switching masks is not sufficient when the patient is not ventilating effectively.

Therefore, immediate BVM ventilation with high-flow oxygen is the appropriate first intervention to support oxygenation and ventilation.
