Which action is included in the steps for an allergic reaction in the office?

• A. Turn Nitrous oxide off
• B. Oxygen up to 8 Lpm
• C. Draw epinephrine 1 mg
• D. Call 911!

Answer: (D)

Emergency response in a dental office must rapidly involve professional help. When a patient has an allergic reaction that could progress to anaphylaxis, the most critical immediate action is to summon emergency medical services so trained responders can arrive quickly, assess airway and circulation, provide advanced care, and transport if needed. Stopping nitrous oxide and giving oxygen are important supportive steps, but they don’t substitute for getting urgent external help. Administering epinephrine is essential in treatment, but the option shown uses an incorrect dosing approach, whereas the key life-saving step emphasized in office protocols is to call 911 right away to activate emergency care.
