Which collection of signs indicates a severe allergic reaction warranting emergency evaluation?
Answer
Widespread hives, swelling of the face or throat, and dizziness
Systemic reactions to jellyfish venom can manifest as severe allergic responses that require immediate advanced intervention, as they suggest rapid entry of venom into the bloodstream or pre-existing high sensitivity. The presence of widespread hives across the body, coupled with symptoms indicating systemic distress such as facial or throat swelling (airway risk) and sudden dizziness, strongly suggests a reaction that surpasses local tissue damage. These signs move the situation into the realm of anaphylaxis, necessitating immediate activation of emergency medical protocols rather than standard first aid or localized treatment.
