A client with a primary brain tumor is to receive radiation after undergoing surgery to remove the tumor. The nurse knows that they may not receive chemotherapy because of the following reason.

Chemotherapy has side effects

Difficulty for chemotherapy to go through the blood-brain barrier

Chemotherapy is not needed with brain tumors as they never metastasize

Chemotherapy is not used to treat cancer

Answer and Explanation

The Correct Answer is B

A. While chemotherapy does have side effects, this is not the primary reason for its limited use in treating brain tumors. Side effects are a consideration but not the main obstacle.

B. The blood-brain barrier is a selective permeability barrier that limits the ability of many chemotherapy drugs to pass from the bloodstream into the brain tissue. This makes it difficult for chemotherapy to effectively treat brain tumors.

C. Brain tumors can metastasize and spread to other parts of the body, so chemotherapy may still be needed, especially in cases of malignant tumors.

D. Chemotherapy is commonly used to treat cancer, including brain tumors, but the blood-brain barrier poses a significant challenge in its effectiveness.

Correct Answer is B

Explanation

A. Weakness in the lower body is not an accurate description of paraplegia. Paraplegia refers to the loss of function, not just weakness.

B. Paraplegia refers to the loss of motor and sensory function in the lower body, including the legs, due to a spinal cord injury, typically below the level of the injury. This is the most accurate response.

C. Temporary loss of motor and sensory functions is more characteristic of conditions like spinal shock, not paraplegia. Paraplegia refers to permanent impairment following spinal cord injury.

D. The description of loss of movement from the neck down is characteristic of quadriplegia (or tetraplegia), not paraplegia, which specifically involves the lower body.

A. Thrombotic stroke B. Cerebral aneurysm C. Embolic stroke D. Hemorrhagic stroke

Correct Answer is C

Explanation

A. A thrombotic stroke is typically caused by a blood clot that forms in an artery supplying blood to the brain, usually due to atherosclerosis. While it is a possible cause of stroke, it is not the most likely in this patient with atrial fibrillation.

B. A cerebral aneurysm involves a weakness in the blood vessel wall that can lead to rupture and bleeding, causing a hemorrhagic stroke, but this is not the most common type of stroke in patients with atrial fibrillation.

C. Embolic stroke occurs when a clot or other debris (such as a thrombus) breaks off from a distant part of the body (like the heart in atrial fibrillation) and travels to the brain, blocking a cerebral artery. This is the most common type of stroke in patients with atrial fibrillation due to the formation of clots in the left atrium that can embolize to the brain.

D. Hemorrhagic stroke is caused by the rupture of a blood vessel in the brain, leading to bleeding. It is not the most common type of stroke in patients with atrial fibrillation, though it can occur if there is coagulopathy or anticoagulant therapy.
