A newly licensed nurse is learning about coup and contrecoup injuries.
Which statement by the newly licensed nurse demonstrates a clear understanding of the topic?
A contrecoup injury is not viewed as a “true” injury, while a coup injury can have more severe consequences.
Contrecoup injuries are generally less severe and heal more quickly over time.
The coup injury is the primary point of injury, with the contrecoup injury occurring on the brain’s opposite side.
The coup injury happens secondary to the contrecoup injury but does not impact the brain’s blood supply.
The Correct Answer is C
Choice A rationale
A contrecoup injury is indeed a “true” injury. It occurs on the side of the brain opposite to the point of impact and can have severe consequences, including brain damage. Therefore, this statement is incorrect.
Choice B rationale
The severity and healing time of contrecoup injuries can vary greatly depending on the force and location of the impact, as well as individual health factors. It’s not accurate to say that contrecoup injuries are generally less severe and heal more quickly over time.
Choice C rationale
This statement is correct. A coup injury refers to the brain damage that occurs directly under the point of impact, while a contrecoup injury occurs on the opposite side of the brain from
where the head is struck. These injuries can occur separately or together, but if the blow is strong enough, they usually appear together.
Choice D rationale
The sequence of coup and contrecoup injuries is not as this choice describes. The coup injury happens at the point of impact, and the contrecoup injury happens when the brain rebounds and hits the opposite side of the skull. Both types of injuries can impact the brain’s blood supply.
