Which option describes a toxic reaction to Hymenoptera stings?

• A. Local reaction
• B. Delayed reaction
• C. Toxic reaction
• D. Systemic/anaphylactic reaction

Answer: (C)

Reactions to Hymenoptera stings can be driven by the venom itself or by an allergic immune response. A toxic reaction is the systemic illness that results from a large venom load, not from prior sensitization. It happens when many stings deliver enough venom to affect multiple organ systems, so you see generalized symptoms such as vomiting, diarrhea, abdominal pain, fever, malaise, dizziness, or confusion, and in severe cases shock or organ dysfunction like kidney injury. There is no antidote for venom toxicity; treatment centers on careful supportive care: secure the airway and breathing, establish good IV access with fluids, manage pain and nausea, monitor for evolving complications, and treat specific problems (for example, renal injury or seizures) as needed. This differs from a local reaction, which is confined to the sting site with swelling at the site, or from a systemic anaphylactic reaction, which is an IgE-mediated allergic response presenting with hives, swelling, bronchospasm, and hypotension and requiring prompt epinephrine.
