The nurse is teaching a client about body defenses. Which defenses should the nurse include in the teaching when referring to innate defenses?
1. The skin
2. Antibody-mediated (humoral) immunity
3. Cell-mediated immunity
4. Immunoglobulins (Ig)
Correct Answer: 1
Rationale 1: The innate defenses are called nonspecific because they are unable to distinguish one type of threat from another; the response or protection is the same regardless of the pathogen. These defenses include physical barriers, such as the skin and the lining of the respiratory and gastrointestinal tracts, which are potential entry points for pathogens.
Rationale 2: This is an example of an adaptive body defense.
Rationale 3: This is an example of an adaptive body defense.
Rationale 4: This is an example of an adaptive body defense.
Global Rationale: The innate defenses are called nonspecific because they are unable to distinguish one type of threat from another; the response or protection is the same regardless of the pathogen. These defenses include physical barriers, such as the skin and the lining of the respiratory and gastrointestinal tracts, which are potential entry points for pathogens. The other choices are examples of adaptive body defenses.
