For anaphylaxis, which statement about epinephrine auto‑injector use is correct?

• A. Administer a single auto‑injector dose
• B. Administer only after confirming no heart disease history
• C. Administer only if the patient is in shock requiring IV fluids
• D. Administer as needed for any allergic reaction regardless of severity

Answer: (A)

Anaphylaxis is a life-threatening allergic reaction that affects multiple systems, especially the airway and circulation. The most important action is to deliver epinephrine as soon as anaphylaxis is suspected because it rapidly reverses airway swelling, relaxes bronchospasm, and counteracts the dangerous blood vessel leakage that can lead to shock. Administering a single auto‑injector dose right away provides this critical, rapid effect and can stabilize the patient. If symptoms persist or recur after about 5 to 15 minutes, a second dose can be given, and the patient should be transported promptly for further care. A history of heart disease is not a contraindication that would justify delaying or withholding epinephrine in the setting of anaphylaxis; it may require careful monitoring, but treatment should not wait. IV fluids are supportive after epinephrine is started, not a prerequisite for giving the epinephrine dose. Epinephrine is not used for any allergic reaction regardless of severity; it is reserved for suspected anaphylaxis or severe systemic reactions with airway compromise or shock.
