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.

Answer and Explanation

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.

Correct Answer is B

Explanation

Choice A rationale
Cancer pain is usually associated with the growth of a tumor or the side effects of cancer treatment. Phantom limb pain is not related to cancer.
Choice B rationale
Phantom limb pain is considered a type of neuropathic pain. This is because it is associated with nerve damage or malfunctioning nerves in the area where the limb was amputated.
Choice C rationale
Chronic pain is a broad term that refers to any pain that lasts for more than 12 weeks. While phantom limb pain can become chronic, this term does not specifically describe the type of pain experienced in phantom limb syndrome.
Choice D rationale
Acute pain is a type of pain that comes on suddenly and has a specific cause, usually related to tissue damage. Phantom limb pain is not considered acute pain because it is not related to new tissue damage.

A. Rebleeding of the injury B. Decreased cerebrospinal fluid C. Use of nimodipine D. Poor functional ability

Correct Answer is A

Explanation

Choice A rationale
Rebleeding of the injury is a significant factor related to a high mortality rate for a client who has a subarachnoid hemorrhage (SAH). SAH is a devastating event with substantial mortality and high morbidity among survivors. The most common primary causes of death or neurological devastation leading to withdrawal of support are direct effects of the primary hemorrhage (55%) and aneurysm rebleeding (17%)2. Therefore, rebleeding of the injury is a critical concern in the management of SAH.
Choice B rationale
Decreased cerebrospinal fluid is not directly linked to a high mortality rate in SAH. While changes in cerebrospinal fluid dynamics can occur after SAH, it’s not typically a primary factor contributing to mortality.
Choice C rationale
The use of nimodipine is actually part of the treatment protocol for SAH. Nimodipine is a calcium channel blocker that is used to prevent cerebral vasospasm, a complication of SAH. It does not contribute to a higher mortality rate.
Choice D rationale
Poor functional ability could be a result of SAH due to neurological damage, but it is not a direct cause of high mortality. The severity of the initial hemorrhage and subsequent

complications like rebleeding or medical complications are more directly tied to mortality rates.
