Question

A client is brought to the physician's office with a raised red macular rash on the trunk and arms accompanied by a fever. A diagnosis of measles is made. Which type of immunity does this disease process provide?

a) Passive artificial immunity
b) Passive natural immunity
c) Active natural immunity
d) Active artificial immunity

Answer 1

Measles provides active natural immunity, as the body's immune system actively responds to infection and develops long-term protection.

Step-by-step explanation:

When a client is diagnosed with measles after exhibiting symptoms such as a raised red macular rash and fever, the type of immunity that this disease process provides is active natural immunity.

This form of immunity occurs because the person's body is exposed to the live pathogen, responds to it by developing an immune response, and ultimately creates memory cells for long-term protection. In contrast to active natural immunity, passive artificial immunity and passive natural immunity involve the introduction of antibodies from another source, rather than the person's own immune system actively responding to the pathogen. Active artificial immunity is the type of immunity obtained through vaccinations where a killed or attenuated pathogen is introduced to the body to elicit an immune response without causing disease.
