An alert, first-party caller reports being bitten by a rattlesnake. What is the best Chief Complaint Protocol?

• A. 3: Breathing difficulties
• B. 2: Allergies (Reactions)/Envenomations (Stings, Bites)
• C. 5: Chest pain
• D. 1: Unknown

Answer: (B)

When a rattlesnake bite is reported, classify it under the Allergies/Reactions/Envenomations (Stings, Bites) protocol. A rattlesnake bite is an envenomation, meaning venom has been injected, so it fits the envenomation category rather than a generic breathing problem, chest pain, or an unknown complaint.

This choice is the best because it guides the call-taker to ask venom-specific questions (time since bite, location of the bite, progression of swelling or pain, numbness, trouble breathing, or other systemic signs) and to provide appropriate pre-arrival instructions and rapid transport. Using a category like breathing difficulties or chest pain would misalign the questions and the guidance with the actual issue, and labeling it unknown would delay obtaining venom-related information.

As you gather details, instruct the caller with standard pre-arrival guidance for envenomation: keep the patient calm, immobilize the affected limb, keep it at or slightly below heart level, remove constrictive items, and avoid cutting, sucking, or tourniquets. These steps help slow venom spread while help is on the way.
