You are called to the scene of an adult patient who was the unrestrained driver in a single-car motor vehicle collision. The patient is pale, cold, and clammy, his pulse is 60 , respirations are 12 , pupils are equal, dilated, and sluggish, and you have weak central pulses and absent peripheral pulses. Your rapid trauma survey reveals a scalp laceration, unequal lung sounds, flattened jugular veins, absent distal pulse, motor and sensory function, and a flail segment to the right anterior chest. Which of the following BEST describes this patient’s situation? Neurogenic shock from a spinal injury. A closed head injury with increasing intracranial pressure. Stage IV hemorrhage with profound hypotension and decompensated shock. Respiratory and obstructive shock from a developing tension pneumothorax.
