A preschooler with suspected poisoning is being treated. Which sequence correctly identifies the poison and prevents further absorption after exposure is terminated?

• A. Assess the victim; Terminate exposure; Identify the poison; Prevent absorption.
• B. Assess the victim; Prevent absorption; Terminate exposure; Identify poison.
• C. Terminate exposure; Identify poison; Assess the victim; Prevent absorption.
• D. Identify poison; Terminate exposure; Assess the victim; Prevent absorption.

Answer: (A)

In suspected poisoning, the priority is to manage the patient and stop further harm before figuring out exactly what toxin is involved. The sequence begins with assessing the child to ensure airway, breathing, and circulation are stable. Once you know the child’s condition, terminate exposure by removing the poison source and any contaminated clothing, and move to a safe environment. This immediate step prevents ongoing absorption and gives the child a better chance to stabilize.

After exposure is halted, identifying the poison becomes crucial. Knowing exactly what substance was involved guides the specific treatment plan, including which decontamination methods are appropriate and whether antidotes or other therapies are needed. With the toxin identified, you tailor steps to prevent absorption effectively, such as targeted skin or eye irrigation, continued removal of contaminated material, and, when indicated by the substance and time since exposure, suitable decontamination like activated charcoal.

In this scenario, prioritizing assessment, stopping exposure, identifying the poison, and then implementing prevention of further absorption aligns steps with the child’s safety and the most effective, informed treatment.
