An asthmatic patient with a rubber dam in place develops wheezing and lip swelling (signs of anaphylaxis). What is the first-line drug?
Show answer and explanation
Correct answer: A. Intramuscular epinephrine
- A. Correct. Epinephrine is the first-line, life-saving treatment for anaphylaxis; activate EMS (call 911) as well.
- B. Incorrect. Antihistamines are adjuncts that treat itching/urticaria; they are not first-line and act too slowly for airway compromise.
- C. Incorrect. Albuterol helps bronchospasm but does not address the systemic anaphylaxis or angioedema.
- D. Incorrect. Corticosteroids have a delayed onset and are adjunctive, not the immediate treatment.
