Anaphylaxis and Allergic Reactions · CDA

Upon recognition of anaphylaxis in a dental clinic patient, what is the first step after suspecting the reaction?

  1. Give the patient an oral antihistamine tablet without delay
  2. Immediately administer supplemental oxygen and nothing else
  3. Remove the trigger, call EMS, and give epinephrine
  4. Wait and observe to see whether the symptoms worsen further
Show answer and explanation

Correct answer: Remove the trigger, call EMS, and give epinephrine

Once anaphylaxis is suspected, the trigger should be removed if possible, EMS called immediately, and epinephrine administered — delay increases risk of deterioration.
