Vital signs: HR 140 beats/min, BP 96/ mmHg, RR 36 breaths/min. He complains of lower abdominal and lower limb pain, with bilateral open tibial fractures. Which of the following statements is TRUE?
A. Pelvic injury can be ruled out based on the mechanism of injury B. Blood loss from the lower limbs is the most likely cause of his tachycardia C. X-rays of the chest and pelvis are important adjuncts in the initial assessment D. Spinal cord injury is the most likely cause of his hypotension
Answer: C
Rationale:
