A nurse is teaching a nursing student about a specific acquired immunity system. Which statement by the student indicates a need for further teaching?
a. "Cell-mediated immunity and humoral immunity are both types of specific acquired immune responses."
b. "Each exposure to an antigen causes a faster, more intense response."
c. "Immune responses occur only after exposure to a foreign substance."
d. "The skin is a factor in specific acquired immunity."
ANS: D
The skin is a physical barrier that confers natural immunity. It is not a factor in specific acquired immunity. Cell-mediated and humoral immunity are both types of specific acquired immunity. In specific acquired immunity, each exposure to an antigen evokes a more intense response more quickly. Specific acquired immunity occurs only after initial exposure to an antigen.
