Emergency Medical Technician (EMT) Trauma Practice Test

The correct answer is B because a gunshot wound to the abdomen can cause significant internal bleeding and requires immediate medical attention. Options A, C, and D do not present with immediate life-threatening injuries and would not require a rapid head-to-toe assessment. Option A is likely a case of a broken femur, which does not pose an immediate threat to the patient's life. Option C involves a fall from 9 feet, which can result in injury but is not as severe as a gunshot wound. Similarly, option D involves minor abrasions and does not require immediate medical attention. Therefore, option B is the most critical case that would require a rapid head-to-toe assessment.
