A 17-year-old patient was stung by a bee and is now confused and short of...

This patient is experiencing anaphylactic shock, evidenced by hypotension, respiratory distress, hypoxia, and altered mental status. After epinephrine administration, NREMT priorities focus on aggressive oxygenation and airway support.

Option D is correct because a non-rebreather mask at high flow delivers the highest concentration of oxygen to a spontaneously breathing patient and is indicated with SpO₂ of 86%.

Option C would be indicated only if respirations were inadequate or absent.

Option B is insufficient for severe hypoxia.

Option A delays definitive supportive care.

NREMT emphasizes epinephrine first, followed immediately by high-flow oxygen and rapid transport.
