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 D

Explanation

A. The client should not sit upright in a chair for prolonged periods (such as 4 hours at a time) immediately following spinal fusion, as this could place excessive strain on the surgical site. The client should be assisted to sit upright for short periods and be repositioned regularly.

B. Clear drainage on the spinal dressing could indicate cerebrospinal fluid leakage, which is a concern following spinal surgery. The nurse should expect minimal to no drainage, and if clear fluid is observed, it should be reported immediately.

C. Elevating the client's legs when lying on his side may not be necessary unless specifically ordered by the healthcare provider. In general, the client should maintain proper body alignment and avoid any positions that strain the surgical site.

D. Log rolling is a critical intervention for spinal fusion patients to prevent twisting of the spine. The nurse should assist the client in log rolling every 2 hours to maintain spinal alignment and prevent injury to the surgical site.

A. Concussion B. Brainstem contusion C. Subdural hematoma D. Epidural hematoma

Correct Answer is A

Explanation

A. A concussion is considered a mild traumatic brain injury (TBI) that typically results in a temporary loss of brain function. It is often caused by a blow to the head and may result in confusion, dizziness, and loss of consciousness. However, if concussions occur repeatedly, they can lead to long-term cognitive impairment and other serious conditions like chronic traumatic encephalopathy (CTE).

B. A brainstem contusion is a more severe injury that affects the brainstem, which controls vital functions like breathing and heart rate. It is not classified as a mild injury.

C. A subdural hematoma is a collection of blood between the brain and its outermost covering. It is a serious condition that can result from a traumatic brain injury and is not considered mild.

D. An epidural hematoma is a collection of blood between the skull and the dura mater. It is often caused by a traumatic head injury and is considered a medical emergency, not a mild injury.
