Answer to Question 1

Answer: D

Hand hygiene is always the first and best way to stop the spread of microorganisms, which cause infections. Raising the temperature in a client's room would contribute to the growth of microorganisms. Assessing vital signs is important but should be done more frequently than once daily. Wearing a mask for all clients is not practical and is unnecessary unless a microorganism is airborne and the client is in isolation.

Answer to Question 2

Answer: A, B, C, E

Macrophages ingest antigens and signal helper T cells that antigens are present. Lymph nodes filter foreign products or antigens from the lymph system and house and support proliferation of lymphocytes and macrophages. Antibodies directly attack and destroy antigens either before or after antigens invade body cells. The immune system damaging the myelin is an autoimmune response in MS. Memory B cells and T cells remember how to identify the antigen and will reactivate at a future time if the same type of antigen is present.
