Question 1

1. The spleen has a number of important functions, which include:

   c. defense from infection, metabolism of vitamins, platelet
   production.
   d. lipid metabolism, production of hemoglobin, water absorption.

Answer 1

b. hematopoiesis, destruction of old erythrocytes, blood reservoir.

Question 2

2. The function of the hormones secreted by the thymus gland is to:
   a. break down old erythrocytes and recycle the

   c. stimulate lymph production.
   d. enable lymphocytes to develop into mature T cells.

Answer 2

d. enable lymphocytes to develop into mature T cells.

Question 3

3. Malignant neoplasms involving lymphocyte proliferation in the lymph nodes are called:
   a. lymphomas
   b. myelomas
   c. lymphocytomas

   b. Ann Arbor cell
   c. Hodgkin’s
   lymphocyte

Answer 4

d. Reed-Sternberg cell

Question 5

5. The staging system typically used in determining the stage of the Hodgkin’s lymphoma is the:
   a. Reed-Sternberg system.
   b. sequential staging system.

   d. differential landmark system.

Answer 5

c. Ann Arbor system.

Question 6

6. One of the reasons non-Hodgkin’s lymphomas are harder to treat than Hodgkin’s lymphomas is that they:
   a. tend to be much larger than Hodgkin’s
   lymphomas.
   b. involve multiple nodes and widespread metastases.
   c. are not affected by the newer drug treatments.
   d. are asymptomatic until they reach stage IV.

Answer 6

b. involve multiple nodes and widespread metastases.

   b. T cells.
   c. NK cells.
   d. monocytes.

Answer 7

condition known as:
a. plasma cell myeloma.
b. diverticulitis.
c. lymphedema.

Answer 8

c. lymphedema.

Question 9

9. A rare illness that involves the overgrowth of lymphoid tissue, although not itself considered a cancer is:
   a. Castleman disease.
   b. hyperlymphatic disease.
   c. hypolymphatic disease.
   d. Ann Arbor disease.

Answer 9

a. Castleman disease.

Question 10

10. Non-Hodgkin’s lymphomas are increasing in incidence, partly due to the numbers associated with:

    microorganisms.
    b. an increase in adult obesity.
    c. an increase in high cholesterol levels.
    d. an increase in HIV infections.
