A nurse is reinforcing teaching with a newly licensed nurse about coup and contrecoup injuries. Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?
A contrecoup injury is not considered a "true" injury, and a coup injury can be more devastating.
The coup injury is the primary focal injury, and the contrecoup injury occurs on the opposite side of the brain.
The coup injury occurs secondary to the contrecoup injury but does not affect blood supply to the brain.
Contrecoup injuries are less severe and easier to heal from over time.
The Correct Answer is B
A. A contrecoup injury is a true injury and can be significant; stating it is not considered "true" is incorrect and indicates a lack of understanding.
B. This statement accurately describes coup and contrecoup injuries, where a coup injury occurs at the site of impact and a contrecoup injury occurs on the opposite side of the brain.
C. This statement is incorrect because a coup injury does not occur secondary to the contrecoup; they can happen simultaneously during trauma.
D. Contrecoup injuries can be just as severe as coup injuries, and the healing process varies; stating they are easier to heal from is misleading and reflects a misunderstanding.
