A parent of a child who has been having frequent bouts of tonsillitis brings the child back to the clinic for another sore throat. The parent asks the nurse, "What are tonsils good for anyway?" What is the best response by the nurse?
A) "They really do not have a function and should be removed."
B) "These tissues filter bacteria from tissue fluid."
C) "The tissue acts as an emergency reservoir of blood."
D) "The tissue removes blood and bacteria."
B
Feedback:
Tonsils and adenoids filter bacteria from tissue fluid. Because they are exposed to pathogens in the oral cavity, they can become infected and locally inflamed. The spleen acts as an emergency reservoir of blood and removes blood and bacteria, not the tonsils.
