LEUKEMIA: 50 MCQs

What is leukemia?

• Cancer starting in blood-forming cells of bone marrow

• Cancer of brain cells

• Cancer of muscle cells

• Cancer of skin cells

Leukemia results from abnormal development of:

• Leukocytes (WBCs)

• Erythrocytes (RBCs)

• Platelets

• Plasma cells

What happens to leukemia cells?

• Look different and do not function properly

• Function better than normal cells

• Only affect the liver

• Only affect the kidneys

The initial pathophysiology involves:

• Malignant transformation of a single stem cell

• Rapid platelet destruction

• RBC membrane defect

• Hormonal imbalance

Leukemia cells have a prolonged lifespan and:

• Accumulate in bone marrow

• Die quickly

• Stay in the liver

• Function normally

Accumulation of leukemia cells leads to:

• Inadequate space for normal blood production

• Increased RBC production

• Increased platelet production

• Hypercalcemia

Lack of normal WBCs increases the risk of:

• Infection

• Dehydration

• Hyperglycemia

• Hyperkalemia

Lack of RBCs in leukemia results in:

• Fatigue and anemia

• Polycythemia

• Dehydration

• Leukocytosis

Lack of platelets in leukemia increases the risk of:

• Bleeding

• Infection

• Weight gain

• Hypertension

Which is a suspected environmental risk for leukemia?

• Smoking

• Low protein intake

• Obesity

• Hyperlipidemia
