According to the presented treatment steps for pit viper bites, which action is recommended first?

• A. Suck venom out
• B. Mark bite site
• C. Ice the limb
• D. Apply tourniquet

Answer: (B)

Marking the bite site is the recommended first action because it creates a clear baseline to observe how quickly swelling and venom spread over time. This baseline helps responders and clinicians gauge envenomation severity during transport and informs decisions about treatment, such as the need for antivenom. The other listed actions are not advised: suctioning venom, icing the limb, or applying a tourniquet can cause tissue damage, delay appropriate care, or worsen outcomes, and they do not effectively prevent the effects of venom. After marking, focus on immobilizing the limb and seeking rapid medical care while monitoring the patient.
