What protocol is appropriate for allergic reactions such as swelling after eating shrimp?

The appropriate protocol for allergic reactions, such as swelling after eating shrimp, is the one focused specifically on Allergies/Envenomations. This protocol is designed to assess and guide dispatchers through the management of allergic reactions, which can manifest as symptoms ranging from mild irritation to severe anaphylaxis. In cases where a person experiences swelling, particularly if it involves the face or throat, it indicates an allergic response that may require immediate medical intervention.

This protocol includes guidance on identifying the severity of the patient's symptoms, determining whether the individual has a known allergy, and advising on possible treatments, such as the administration of epinephrine if anaphylaxis is suspected. In particular, understanding the nature of the allergen and the patient's previous reactions to similar allergens is crucial for effective dispatching.

The other options do not align with the specific concern of an allergic reaction to food. Choking protocols focus on obstruction of the airways, breathing problems protocols deal with respiratory distress unrelated to allergic reactions, and cardiac or respiratory arrest protocols are concerned with life-threatening emergencies that are distinct from allergic responses. Therefore, selecting the protocol specifically designated for allergies ensures that the dispatcher provides appropriate and timely guidance to the caller in the event of an allergic reaction.
