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 A

Explanation

A. Attempt to determine what the client was looking for is the best response. In Alzheimer's disease, clients may exhibit wandering behavior and confusion, often seeking something familiar or trying to meet an unmet need. Understanding what the client was looking for can help address their needs and prevent further agitation.

B. Reprimanding the client for invading the other client's privacy is not appropriate. Clients with Alzheimer's disease may not be aware of the concept of privacy or the impact of their actions. Reprimanding can cause distress and confusion.

C. Explaining the client's Alzheimer's diagnosis to the frightened client may help provide understanding, but it does not address the immediate concern of calming the frightened client. The focus should be on managing the behavior in the moment.

D. Asking the client to apologize for his behavior is not appropriate, as the client may not have the cognitive ability to understand or remember the need to apologize. This could cause frustration and confusion.

A. Vitamin K B. Naloxone C. Disulfiram D. Protamine

Correct Answer is A

Explanation

A. Vitamin K is the antidote for excessive anticoagulation caused by warfarin. It helps to reverse the effects of warfarin by promoting the synthesis of clotting factors.

B. Naloxone is used to reverse opioid overdose, not related to warfarin or its effects.

C. Disulfiram is used to treat alcohol use disorder by causing unpleasant effects when alcohol is consumed, and is unrelated to warfarin.

D. Protamine is used to reverse the effects of heparin, not warfarin.
