The correct answer is D. Ensure that secondary triage is completed.

Role of Treatment Supervisor in MCI (Mass Casualty Incident):

In the Incident Command System (ICS), responsibilities are divided:

Triage Supervisor → performs initial triage

Treatment Supervisor → manages patient care after triage

Transport Supervisor → coordinates transport to hospitals

Staging Officer → manages personnel/equipment staging

Primary responsibility of Treatment Supervisor:

Oversee treatment areas (Immediate, Delayed, Minor)

Ensure patients are reassessed and re-triaged (secondary triage)

Monitor patient conditions and prioritize care

NREMT-aligned guidance states:

“The treatment supervisor is responsible for patient care and reassessment.”

“Secondary triage is performed in the treatment area.”

Why D is correct:

Secondary triage ensures patients are:

Reevaluated

Properly prioritized as conditions change

This is a core responsibility of the treatment supervisor

Why the other options are incorrect:

A. Command triage personnel→ Responsibility of the Triage Supervisor

B. Establish staging area→ Responsibility of the Staging Officer

C. Coordinate transportation→ Responsibility of the Transport Supervisor

Exact Extracts (NREMT-aligned EMT educational references):

“Treatment unit is responsible for treatment and secondary triage.”

“Transport officer coordinates patient movement to hospitals.”

“Staging manages resources and personnel.”

Clinical Priority Summary:

The treatment supervisor’s primary role is to manage patient care and ensure ongoing reassessment, including secondary triage, making D the correct answer.
