A nurse is gathering neurological data on a patient with a neurological injury and observes signs indicative of Cushing’s Triad.
The nurse understands that Cushing’s Triad is a nervous system response that could prevent which of the following conditions?

Choice A rationale
Vision loss and depression are not typically symptoms of a mild traumatic brain injury (TBI). Vision loss could be a symptom of a more severe TBI or other neurological conditions.
Depression, while it can occur following a TBI, is not a direct symptom of the injury itself but rather a common psychological reaction to the changes and challenges that a person may face following the injury.
Choice B rationale

Seizures and weakness in the extremities can be symptoms of a TBI, but they are more commonly associated with moderate to severe TBIs. Mild TBIs do not typically cause seizures or weakness in the extremities.
Choice C rationale
Persistent headache can be a symptom of a mild TBI. However, aggressive behavior, while it can occur following a TBI, is not a direct symptom of the injury itself but rather a possible psychological reaction to the changes and challenges that a person may face following the injury.
Choice D rationale
Headache and confusion are common symptoms of a mild TBI. After a mild TBI, individuals may experience a headache or a feeling of pressure in the head. They may also experience confusion or feel as if in a fog.

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.
