  The physician explains the damage that could occur to lung tissue by Mycobacterium tuberculosis. Which of the following phenomena would underlie the physician's explanation?
  A)
  Tissue destruction results from neutrophil deactivation.
  B)
  Nonspecific macrophage activity leads to pulmonary tissue destruction and resulting hemoptysis.
  C)
  Macrophages form a capsule around the Mycobacterium tuberculosis bacteria, resulting in immune granulomas.
  D)
  Neutrophils are ineffective against the Mycobacterium tuberculosis antigens.

Question 2

A 60-year-old woman is suspected of having non-Hodgkin lymphoma (NHL). Which of the following aspects of her condition would help to rule out Hodgkin lymphoma?
 
  A)
  Her neoplasm originates in secondary lymphoid structures.
  B)
  The lymph nodes involved are located in a large number of locations in the lymphatic system.
  C)
  The presence of Reed-Sternberg cells has been confirmed.
  D)

Answer to Question 1

Ans:
C

Feedback:

Immune granulomas are caused by insoluble particles (Mycobacterium tuberculosis) that are capable of inciting a cell-mediated immune response. Neutrophils are deactivated, self-destructive, nor ineffective in cases of tuberculosis.

Answer to Question 2

Ans:
B

Feedback:

While NHLs tend to be multicentric, Hodgkin lymphoma tends to involve a single node or group of nodes. The presence of Reed-Sternberg cells would indicate Hodgkin lymphoma, and both NHL and Hodgkin lymphoma involve secondary lymphoid structures and would cause fatigue.
