A 19 year old female fell from a second story window and landed on her head. She is unconscious with a blood pressure of 168/104mmHG, heart rate of 56bpm, and irregular respirations of 8 breaths/min. Further assessment reveals blood draining from her nose and bilaterally dilated pupils that are slow to react. In addition to employing full spinal precautions, the MOST appropriate treatment for this patient involves:A. Applying oxygen via nonrebreathing mask, covering her with blankets, starting an IV of normal saline set to keep the vein open, applying a cardiac monitor, initiating transport, and monitoring her pupils while en route to the hospitalB. Intubating her trachea after preoxygenating her for 2 to 3 min with a bag-mask device, transporting immediately, starting at least one large-bore IV en route, applying a cardiac monitor and performing frequent neurologic assessmentsC. Hyperventilating her with a bag-mask device at a rate of 20 breaths/min, starting two large-bore IVs, applying a cardiac monitor, administering 5 mg of Valium to prevent seizures, and transporting to a trauma centerD. Preoxygenating her with a bag-mask device and 100% oxygen for 2 to 3 min, performing nasotracheal intubation, transporting at once, starting at least one large-bore IV line en route and obtaining her Glasgow Coma Scale score
