The LPN/LVN cares for a client newly diagnosed with paranoid schizophrenia. The client tells the LPN/LVN, "There are really strange people in the corner of my room laughing at me and saying horrible things." Which of the following responses by the LPN/LVN is MOST appropriate?

1. "I don't see anything, and you really have nothing to be ashamed of."
2. "I don't hear the voices, but this seems to be frightening you."
3. "What are they saying to you?"
4. "Sometimes when people are upset, their imagination plays tricks on them."

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
