Ms. L, a 19-year-old woman with no previous medical history, was involved in a serious automobile accident in which her best friend died. Examination by EMT personnel first on the scene revealed she had only minor scrapes and bruises and no sign of head trauma. While en route by ambulance to the hospital, Ms. L complained of thirst and appeared restless. Further examination indicated a rapid pulse and respiration, with her blood pressure now at 100/60 mm Hg. She appeared less responsive to the paramedics so they checked her again for internal injuries. Question:Based on the clinical presentation of this case, what is your final diagnosis? Why?
