The correct answer is D. Administer oxygen by non-rebreather mask.
Anaphylaxis (bee sting)
Hypotension (78/60) → shock
Tachycardia (140)
Low SpO₂ (86%)
Shortness of breath
This is a life-threatening allergic reaction requiring aggressive airway and oxygen management.
Provides high-flow, high-concentration oxygen (up to ~90–95%)
Indicated for patients with:
Hypoxia (SpO₂ < 94%)
Respiratory distress
Shock states
After epinephrine, oxygen therapy is the next immediate step
A. Closely monitor SpO₂ → Monitoring alone is insufficient; intervention is needed
B. Nasal cannula → Delivers low-flow oxygen, inadequate for severe hypoxia
C. Assist ventilations with BVM → Indicated only if respiratory failure or inadequate breathing, not yet present
“Administer high-flow oxygen to patients with hypoxia or respiratory distress.”
“Anaphylaxis requires epinephrine and supportive airway/oxygen management.”
“Use a nonrebreather mask for patients requiring high-concentration oxygen.”
