Correct answer: C — Epinephrine 0.3-0.5 mg IM

After failure of salbutamol (short-acting β2 agonist) to relieve severe bronchospasm/asthma in the dental office, epinephrine 0.3-0.5 mg IM (1:1,000) is the next-line emergency treatment. Epinephrine provides potent β2-mediated bronchodilation plus α1-mediated reduction of bronchial mucosal oedema. EMS (911) should be activated. The patient should be positioned upright. Supplemental oxygen should be administered. IV corticosteroids (hydrocortisone) have delayed onset (1+ hour) and serve as adjunctive rather than immediate therapy.
