Paul is a 23-year-old. He was the victim of a hit-and-run auto-pedestrian accident and suffered multiple abrasions, a concussion, and a deep laceration of his left thigh. He was discovered approximately 2 hours after the incident and is now in the emergency department. Paul’s vital signs and hematocrit suggest that he has had a blood loss of about 2,500 ml. A urinary catheter is inserted to monitor urine output, and fluid resuscitation is initiated while his wounds are cleaned and sutured. The urine output is averaging 15 ml/hr, with a high urine osmolality and low urine sodium. Without adequate therapy, what may develop? Why? What is the best therapy for preventing this from occurring?
