Dentistry · Medical emergencies: anaphylaxis

Sample item

A patient develops generalized urticaria, wheeze, throat tightness, and hypotension after a drug exposure in clinic. What is the first-line medication?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Intramuscular adrenaline

Anaphylaxis is a life-threatening airway, breathing, or circulation reaction. Intramuscular adrenaline is first-line treatment while emergency services are activated and supportive care is provided.

Option by option

  • A. Insulin

    Insulin does not treat allergic anaphylaxis.

  • B. Intramuscular adrenaline (correct)

    Correct. IM adrenaline treats bronchospasm, vasodilation, and airway edema in anaphylaxis.

  • C. Nitroglycerin

    Nitroglycerin can worsen hypotension.

  • D. Oral antihistamine only

    Antihistamines are adjuncts and do not replace adrenaline in anaphylaxis.
