ADVANCED CARDIOVASCULAR AND
HEMATOLOGY QUIZ (BIOD 152 LAB 2)
QUESTIONS AND ANSWERS (VERIFIED
ANSWERS)
1. Which plasma protein is primarily responsible for maintaining the colloid osmotic pressure
of the blood?
A. Fibrinogen
B. Prothrombin
C. Gamma globulin
D. Albumin
Answer: D
Conceptual Explanation: Albumin is the most abundant plasma protein and exerts
significant osmotic pressure to maintain blood volume and pressure.
2. A patient’s hematocrit is measured at 52%. What condition does this most likely indicate?
A. Anemia
B. Leukopenia
C. Polycythemia
D. Thrombocytopenia
,Answer: C
Conceptual Explanation: Hematocrit represents the percentage of red blood cells in total
blood volume. Values significantly above the normal range (approx. 45%) indicate
polycythemia.
3. In the process of hemoglobin breakdown, which component is converted into bilirubin?
A. Globin
B. Heme
C. Iron
D. Transferrin
Answer: B
Conceptual Explanation: After iron is removed from the heme group, the remaining
pigment is converted to biliverdin and then to bilirubin, which is excreted by the liver.
4. Which hormone, produced by the kidneys, stimulates the production of erythrocytes in
response to low oxygen levels?
A. Thrombopoietin
B. Erythropoietin
C. Aldosterone
D. Angiotensin
Answer: B
, Conceptual Explanation: Erythropoietin (EPO) is released by the kidneys during hypoxia
to trigger red bone marrow to increase erythropoiesis.
5. Which leukocyte is typically the first to arrive at a site of bacterial infection and utilizes
respiratory bursts to kill pathogens?
A. Neutrophil
B. Monocyte
C. Eosinophil
D. Lymphocyte
Answer: A
Conceptual Explanation: Neutrophils are the most numerous leukocytes and serve as the
primary phagocytic defense against acute bacterial infections.
6. A person with Type B+ blood can safely receive a transfusion from which of the following
donors?
A. Type AB+
B. Type AB-
C. Type A+
D. Type O-
Answer: D
