In a motor vehicle collision with head injury, which treatment has the highest priority for the patient?

• A. Administer high flow oxygen to encourage oxygen uptake by the hemoglobin
• B. Repeat vital signs every 5 minutes to monitor for pulmonary edema
• C. Initiate 2 large bore catheters of NS for medication ports
• D. Hyperventilate the pt to increase circulation CO2 levels

Answer: (D)

The first priority in a motor vehicle collision with head injury is ensuring airway and breathing to prevent hypoxia. Brain tissue is extremely sensitive to low oxygen, and maintaining high oxygen delivery helps minimize secondary brain injury. Giving high-flow oxygen maximizes oxygen saturation and supports brain oxygenation as you rapidly assess and treat the patient. Monitoring vital signs and establishing intravenous access are important steps, but they don’t address the immediate need to keep the patient oxygenated and breathing adequately. Hyperventilating the patient to raise CO2 levels is not correct in this context: hyperventilation lowers CO2 and causes cerebral vasoconstriction, which can reduce cerebral blood flow and worsen brain injury unless used only in specific, time-limited situations such as signs of herniation under careful monitoring.
