Which of the following disasters would implement disaster medical assistance teams (DMATs)? (Selectone that does not apply.)

Correct Answer: A

Rationale: A presidentially declared disaster is one that requires implementation of disaster medical assistance teams (DMATs) because the disaster exceeds the capabilities of the involved state(s) to provide a timely and effective response. Such a disaster has the potential to cause a substantial number of deaths or injuries; substantial health and medical problems; or significant damage to the economic and physical infrastructure. The disaster may not cover a broad geographic area. The criteria for use of DMATs is that the disaster exceeds the capabilities of the involved state to provide a timely and effective response. This could occur in a small geographic area.
