A patient is diagnosed with a positive tuberculosis skin test. The nurse understands that this response is due to what?
 
  1. performing a cell-mediated inflammatory response
  2. promoting phagocytosis of the antigen by neutrophils
  3. clumping antigens to form a noninvasive aggregate
  4. coating the antigen with antibodies

Question 2

A patient's white blood cell count is 11,000/mm3. What does the nurse understand this value to represent?
 
  1. the total number of circulating leukocytes
  2. the total number of circulating neutrophils
  3. the total number of circulating eosinophils
  4. the total number of circulating basophils

Answer to Question 1

Correct Answer: 1

The cell-mediated response has memory, and subsequent exposures to an antigen result in a more rapid and effective inflammatory response. This memory provides the basis for skin testing. A patient previously exposed to tuberculosis develops a more pronounced inflammatory response when minute amounts are injected under the skin. The other choices are characteristics of an antibody-mediated immune response.

Answer to Question 2

Correct Answer: 1

In laboratory tests, the WBC count indicates the total number of circulating leukocytes. The differential identifies the total number of circulating neutrophils, eosinophils, and basophils.
