  Which of the following statements that he reads on various Web sites is most reliable?
  A)
  Like most forms of Hodgkin lymphoma, mature B-cell lymphoma often requires radiation treatment.
  B)
  Doctors are able to diagnose mature B-cell lymphoma by the presence of Reed-Sternberg cells.
  C)
  Unlike many other lymphomas, mature B-cell lymphoma is often self-limiting, and treatment is focused on symptoms.
  D)
  The lymph nodes are usually affected, and often the spleen and bone marrow.

Question 2

A 14-year-old boy has been diagnosed with infectious mononucleosis. Which of the following pathophysiological phenomena is most responsible for his symptoms?

  B)
  Viruses are killing some of his B cells and becoming incorporated into the genome of others.

Answer to Question 1

Ans:
D

Feedback:

The NHL subtypes of mature B-cell lymphoma may affect the lymph nodes, spleen, or bone marrow. It is not a type of Hodgkin lymphoma, and Reed-Sternberg cells would indicate Hodgkin lymphoma. It is not self-limiting and necessitates active treatment.

Answer to Question 2

Ans:
B

Feedback:

B lymphocytes all of which have receptors for the EBV that causes mononucleosis. Infection of the B cells may take one of two formsit may kill the infected B cell, or it may become incorporated into its genome. Lysis of neutrophils or inhibition of white cell maturation or differentiation is not a central component of mononucleosis etiology.
