1. A two-door passenger car struck a tree while driving approximately 50 MPH. The doors are badly damaged and jammed and the driver appears to be unconscious inside the vehicle. Entering the vehicle by breaking the back window is an example of:

A. simple access.

B. complex access.

C. technical rescue.

D. disentanglement.

Review

Answer: B

Rationale: Complex access requires the use of special tools and special training and includes breaking windows or other forcible entry. Simple access does not involve the use of any tools; examples of simple access include opening a door or rolling down a window. Technical rescue involves the use of specialized teams (ie, trench rescue, high-angle rescue, swift water rescue). Disentanglement involves the removal of a motor vehicle from around the patient (ie, Jaws of Life).

2. What is the first phase of extrication?

A. Arrival

B. Preparation

C. Scene size-up

D. Gaining access

Review

Answer: B

Rationale: There are ten phases of extrication; preparation is the first. Preparing for an incident requiring extrication involves training for the various types of rescue situations your team might face. Just as you must check the equipment on the ambulance, rescue personnel must routinely check the extrication tools and their response vehicle to ensure proper operation. Preparation reduces the possibility of equipment failure at a scene.
