What are monitoring requirements after administering adrenaline for anaphylaxis?

• A. Continuously monitor vital signs (BP, pulse, respiration, oxygen saturation), watch for relapse or biphasic reaction, and be prepared to administer additional adrenaline and provide ongoing support until EMS arrives.
• B. Stop monitoring after 5 minutes.
• C. Only monitor BP.
• D. Discontinue oxygen.

Answer: (D)

Monitoring after adrenaline for anaphylaxis centers on keeping the patient safe during the immediate high‑risk period and watching for relapse or a biphasic reaction. The best approach is continuous monitoring of vital signs—blood pressure, pulse, respiration, and oxygen saturation—with readiness to intervene if the patient deteriorates. Anaphylaxis can recur after initial improvement, so observation continues until transfer to EMS or hospital care is ensured. Be prepared to administer additional doses of adrenaline if symptoms persist or recur, and provide ongoing supportive care such as airway management and fluids as needed. Oxygen should be continued to maintain adequate oxygenation, not stopped, to support tissue oxygen delivery. Have resuscitation equipment available and monitor the patient until stability is confirmed and professional care is in place.
