A nurse is caring for a client who has chronic migraine headaches.
The client asks if they had a cerebral aneurysm, which of the following responses should the nurse use?

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.

Choice A rationale
Trigeminal neuralgia is a chronic pain condition that affects the trigeminal nerve, which carries sensation from your face to your brain. It does not cause a sensation of tightness around the torso.
Choice B rationale

Lhermitte’s sign is a symptom of multiple sclerosis and other neurological conditions where a person feels an electric shock-like sensation running down the spine and into the limbs. It does not cause a sensation of tightness around the torso.
Choice C rationale
The sensation of tightness around the torso in a patient with multiple sclerosis is often referred to as the “MS hug”. It is caused by a lesion or an area of active inflammation within the spinal cord.
Choice D rationale
Paroxysmal spasms are a type of muscle spasm experienced by some people with multiple sclerosis. These spasms are usually painful and involve the muscles of the legs, but they do not cause a sensation of tightness around the torso.
