As you approach the scene of a mass casualty situation in a downtown office building, you note the slight odor of almonds as you see many victims in the lobby lying unconscious with no apparent injury. Your BEST actions should be:
A) remain upwind, away from the site, as this is possibly an asphyxiant.
B) immediately extricate the nearest victim to an area of safety.
C) administer a Mark I kit to all victims within the first five minutes.
D) note the odor and continue with triage of all victims.
A) remain upwind, away from the site, as this is possibly an asphyxiant.

As your rescue unit arrives at the scene of a possible terrorist explosion, one of your primary concerns should be:
A) the possibility of a secondary explosive device.
B) rapid transport of as many patients as possible to the nearest hospital.

You are participating in a training exercise for an attack by a weapon of mass destruction involving the release of a nerve agent. In the triage area, you are presented with a patient who responds to painful stimuli and has an open airway. He is breathing eight times a minute and has a weak radial pulse. He also has wheezing and pinpoint pupils. In his pocket he has a metered-dose inhaler containing albuterol. When caring for this patient, you should FIRST:
A) administer positive pressure ventilation.
B) obtain vital signs, including the temperature.
C) look for an injury causing shock.
D) administer albuterol with the metered-dose inhaler.
A) administer positive pressure ventilation.
