Which of the following is a benefit of communicating with the casualty during Tactical Field Care? a. Facilitate handoff of casualty information to medical personnel b. Ease the casualty's fears and help explain care c. Expedite the casualty evacuation process d. Provide the necessary information for the first section of the 9-Line evacuation request - ANSWER b.

Rapid field test of visual acuity b. Neurological exam c. Traumatic brain injury evaluation questionnaire d. Gait and balance assessment - ANSWER a. Rapid field test of visual acuity RATIONALE If a penetrating eye injury is noted or suspected, perform a rapid field test of visual acuity and document findings.

Using the Rule of Nines, what percent of body surface area is considered burned if the entire anterior torso and the front and back of both lower extremities are burned? a. 35% b. 37% c. 45% d. 54% - ANSWER d. 54% RATIONALE Eleven areas each have 9% body surface area (head, upper extremities, front and back of lower extremities, and front and back of the torso having two 9% areas each). General guidelines are that the size of the palm of the hand represents approximately 1% of the burned area. When estimating, it is easiest to round up to the nearest 10. If half of the front or rear area is burned, the area would be half of the area value. For example, if the entire anterior torso and the front and back of both lower extremities are burned, it would be (9% x 4) + 18% = 54%. What is the most common cause of preventable combat death? a. Tension pneumothorax b. Airway problems c. Shock d. Hemorrhage - ANSWER d.

Tactical Combat Casualty Care (TCCC) Guidelines recommend that combat trauma casualties without a pulse or respirations should have ____________________ performed during Tactical Field Care (TFC) due to the potential benefit and clear absence of additional harm. a.

Bilateral needle decompression of the chest RATIONALE During TFC, several authors and subject matter experts recommend that for combat trauma casualties without a pulse, bilateral NDCs should be performed due to the potential benefit and clear absence of additional harm. As a result, the TCCC Guidelines now state: ".... casualties with torso trauma or polytrauma who have no pulse or respirations during TFC should have bilateral needle decompression performed to ensure they do not have a tension pneumothorax prior to discontinuation of care."
