A Client Asks the Nurse Why Lung Cancers Are Less

A client asks the nurse why lung cancers are less sensitive to antineoplastic agents. Which response should the nurse provide the client?

A) "Lung cancer cells have a very erratic cell cycle, and this is why there isn't much difference between the number of replicating and resting cells."
B) "Lung cancer cells have been growing for a long time before detection, so they are less sensitive to antineoplastic agents."
C) "Lung cancer cells have a low growth fraction, which means there isn't much difference between the number of replicating and resting cells."
D) "Lung cancer cells grow in a high-oxygen environment, so they are not very sensitive to antineoplastic agents."
