• Pale color of the skin can be an indication of anemia, however, it isn’t always easy to assess this in a person of color. To make a quick assessment of his own status, Nathan looked at

  • nail beds.

  • all listed choices.

  • oral mucus membranes.

  • conjunctiva.

The aspects of Nathan's blood panel that conerned him were

• anemia indicated by a low red blood cell count.

• a low platelet count.

• an elevated white blood cell count.

• There are several varieties of leukemia and they are categorized by

  multiple choice 1

  • the size of the malignant cells.

  • the color and staining properties of the remaining healthy cells of the bone marrow.

  • the kind of symptoms the person presents with; bleeding, anemia or repeat infections.

  • the cell of origin (granulocyte or lymphocyte) and their clinical course (acute vs. chronic).

the cell of origin (granulocyte or lymphocyte) and their clinical course (acute vs. chronic).

The underlying problem in all forms of leukemia leading to the patient’s clinical symptoms and potentially their death is that

the clinical symptoms of anemia, bleeding and infections that result from a lack of normal RBCs, WBCs and platelets.

The underlying cause of Nathan's type of leukemia (CGL) is

multiple choice 1

• a vitamin and amino acid deficiency.

• unknown.

• a chromosomal translocation that results in a fusion gene that codes for a novel enzyme that causes the malignant cells to rapidly reproduce.

The medication Gleevec brings about the death of malignant cells in the bone marrow in CGL, but spares the healthy ones because

• 
  Gleevec is radioactive, and when it is taken up by the malignant cell it discharges its radioactive energy killing the cell.

• Geelvec was specifically designed to bind to the novel enzyme (product of the fusion gene) that is found only in the malignant cells, and by halting its action the malignant cells stop proliferating and die.

• Gleevec interferes with vitamin and nutrient uptake by the malignant cells, thus leading to their death.
