A patient with a suspected head injury following an assault is being transported to the emergency department. What would the nurse expect the physician to order to aid in preventing secondary injury?
A) PET
B) CBC
C) ABG
D) MRI
Ans: C
Feedback: Treatments to prevent secondary injury include stabilization of cardiovascular and respiratory function to maintain adequate cerebral perfusion, control of hemorrhage and hypovolemia, and maintenance of optimal blood gas values. PET scans and an MRI would not aid in preventing secondary injury to this patient's brain. An ABG would give baseline blood values to have a foundation in the maintenance of optimal blood gas values.
