What is an indicator to escalate care for a scorpion sting in EMS?

• A. Only local pain.
• B. Signs of systemic symptoms or anaphylaxis.
• C. No swelling.
• D. Allergic reaction to bee sting.

Answer: (B)

Systemic involvement or anaphylaxis signals that the venom is affecting multiple body systems and that the situation can deteriorate quickly, so higher level care is needed. Most scorpion stings cause only local pain and sometimes swelling; those cases can often be managed with supportive care on scene and observation. When systemic signs appear—such as confusion, agitation, dizziness, sweating, nausea or vomiting, abdominal cramps, muscle twitching or weakness, rapid heartbeat, high blood pressure, or trouble breathing—the patient may be headed for more serious effects on the heart, lungs, or nervous system. These changes mean brief on-scene care may not be enough, and transport to an advanced facility is warranted for closer monitoring and potential hospital treatments.

Anaphylaxis is a specific, life-threatening allergic reaction that can occur with scorpion stings. Signs include swelling of the lips or tongue, throat tightness or hoarseness, stridor or severe wheeze, widespread hives, abdominal pain, dizziness, and a drop in blood pressure. If these are present, it’s a clear trigger to escalate care immediately and expedite rapid transport, following protocol for suspected anaphylaxis.

Why the other options don’t fit: local pain alone is a limited sign and typically doesn’t require escalation unless it progresses; absence of swelling doesn’t rule out systemic involvement if other signs are present; a history of an allergic reaction to a bee sting doesn’t by itself indicate escalation for a scorpion sting unless there are actual signs of anaphylaxis from the scorpion sting.
