Which statement about epinephrine administration is true?

• A. It is given orally in most emergency situations
• B. It is never given intravenously
• C. It is typically given intramuscularly via autoinjector in emergencies
• D. It is only used in cardiac surgery

Answer: (C)

In emergencies, epinephrine is given intramuscularly via an auto-injector because it delivers a rapid, reliable dose that bystanders or first responders can administer quickly. The IM thigh injection provides fast peak levels and a straightforward delivery method, which is crucial when time is critical in reactions like anaphylaxis. Oral administration isn’t practical in these situations because absorption is unpredictable and too slow to halt progressive symptoms. Intravenous use exists, but it requires a controlled setting with careful monitoring due to the higher risk of serious side effects like arrhythmias and dangerous blood pressure changes; it’s not the typical approach for most emergency scenarios. Epinephrine is used far beyond cardiac surgery—its primary emergency role is reversing severe allergic reactions, with additional uses in bronchospasm and resuscitation when appropriate.
