A client admitted for fever, crackles in the lungs, and cough asks the nurse, "If they do not know what type of bacteria caused my pneumonia, why are they giving me these antibiotics?" What is the appropriate response by the nurse?

"We give antibiotics to treat the virus that is causing your pneumonia."

"The antibiotics we are giving you will boost your immune system and help fight off whatever pathogen is present."

"We are giving you broad-spectrum antibiotics because they are active for many types of bacteria."

"You cannot be admitted to the hospital with pneumonia without receiving some sort of antibiotics."
