In a toxin exposure where there is no readily available antidote, what is the priority intervention?

• A. Isolate all individuals
• B. Provide supportive care until antidote is available
• C. Administer antidote immediately
• D. Wait for symptoms to appear

Answer: (B)

When a toxin exposure has occurred and no antidote is readily available, the immediate goal is to support the patient’s life functions while the toxin is dealt with or eliminated. Stabilizing the airway, breathing, and circulation is the top priority because rapid deterioration from respiratory failure, hypoxia, or shock can occur with many toxic exposures. Provide ongoing monitoring and treat emerging problems such as seizures, arrhythmias, or hypotension; give fluids or other supportive therapies as needed to maintain perfusion and organ function.

Decontamination and removing the exposure source help limit additional absorption, but they do not replace the need for supportive care. An antidote would be ideal, but if it isn’t available right away, you work to keep the patient stable until it can be administered or until the toxin clears. Waiting for symptoms to appear risks sudden and severe deterioration before you can intervene.

Isolating others from exposure is important for safety, but the priority in this scenario is maintaining the patient’s vital functions through supportive care until an antidote becomes available.
