About This Quiz
Different blood cells in the human body form through the hematopoietic process, which starts when an embryo is formed. Cells play a major role in the human body, especially the white blood cells, which fight infections throughout the body and are transported by the lymphatic system. Test your understanding of the Hematopoietic and lymphoid system by taking this test.

Which of the following are causes of anemia? A. Diminished erythropoiesis B. Hemplysis C. Hemorrhage
-
All of the above
-
None of the above
-
A and B only
-
A and C only
-
B and C only
Correct Answer
A. All of the aboveExplanation
All of the above are causes of anemia. Diminished erythropoiesis refers to a decrease in the production of red blood cells, which can lead to anemia. Hemolysis refers to the destruction of red blood cells, which can also result in anemia. Hemorrhage, or excessive bleeding, can cause a significant loss of red blood cells and lead to anemia as well. Therefore, all three options listed (A, B, and C) are valid causes of anemia.Rate this question:

Which of the following is NOT a component of a CBC? A. WBC B. Platelets C. Glucose content D. Hemoglobin E. Indicies of RBC
-
A
-
B
-
C
-
D
-
E
Correct Answer
A. CExplanation
Glucose content is not a component of a complete blood count (CBC). A CBC typically includes the measurement of white blood cells (WBC), platelets, hemoglobin, and indices of red blood cells. Glucose content is not directly related to the composition of blood and is typically measured separately in a blood glucose test.Rate this question:

Which of the following statements pretain to Intravascular hemolytic anemias? A. It is more common than extravascular hemolytic anemia B. It takes place in the spleen or liver C. May be caused due to mechanical trauma, biochemical/physical agents
-
A
-
B
-
C
-
A and B only
-
All of the above
Correct Answer
A. CExplanation
Intravascular hemolytic anemias are characterized by the destruction of red blood cells within the blood vessels. The correct answer, option C, states that intravascular hemolytic anemias may be caused due to mechanical trauma, biochemical/physical agents. This means that factors such as physical injury or exposure to certain chemicals or substances can lead to the destruction of red blood cells within the blood vessels. Options A and B are incorrect because they do not pertain specifically to intravascular hemolytic anemias.Rate this question:

Which of the following statements is false regarding malaria? A. It is endemic in Asia and Africa B. Red cells are destroyed and the patient suffers from chills and fever C. Malarial parasite is released approximately every 48 hours. D. HbA is protective against malaria
-
A
-
B
-
C
-
D
Correct Answer
A. DExplanation
HbA is not protective against malaria. Malaria is caused by the Plasmodium parasite, which infects and destroys red blood cells. This leads to symptoms such as chills and fever. Malaria is endemic in Asia and Africa, and the malarial parasite is released approximately every 48 hours as part of its life cycle. However, HbA, which is the normal adult hemoglobin, does not provide any protection against malaria.Rate this question:

Anemias of diminished erythropoiesis can be caused by bone marrow failure or replacement by tumor or inflammatory cells.
-
True
-
False
Correct Answer
A. TrueExplanation
This statement is true because anemias of diminished erythropoiesis can indeed be caused by bone marrow failure or replacement by tumor or inflammatory cells. Bone marrow failure can occur due to various reasons such as genetic disorders, radiation or chemotherapy, or certain medications. Additionally, tumors or inflammatory cells can infiltrate the bone marrow, leading to a decrease in the production of red blood cells and resulting in anemia.Rate this question:

Both folate deficiency and Vitamin B12 deficiency are examples of macrocytic anemias.
-
True
-
False
Correct Answer
A. TrueExplanation
Both folate deficiency and Vitamin B12 deficiency can lead to macrocytic anemia, which is characterized by the presence of larger than normal red blood cells. This condition occurs when there is a disruption in the production of red blood cells, leading to fewer and larger cells being produced. Folate and Vitamin B12 are both essential for the production of red blood cells, and a deficiency in either nutrient can result in macrocytic anemia. Therefore, the statement is true.Rate this question:

Which of the following is NOT a cause for the malabsorption in pernicious anemia? A. Gastrectomy B. Diseases involving the distal ileum C. Resection of the ileum D. Due to the autoimmune reaction against intrinsic factor
-
All of the above
-
NONE of the above
-
B and C only
-
D only
Correct Answer
A. NONE of the aboveExplanation
The correct answer is "NONE of the above." This means that all of the options listed (A, B, C, and D) are causes for malabsorption in pernicious anemia. Pernicious anemia is caused by a deficiency of intrinsic factor, which is necessary for the absorption of vitamin B12. Gastrectomy, diseases involving the distal ileum, and resection of the ileum can all lead to malabsorption of vitamin B12. Additionally, the autoimmune reaction against intrinsic factor can also cause malabsorption. Therefore, none of the options listed are excluded as causes for malabsorption in pernicious anemia.Rate this question:

Acute leukemia is a malignancy of the hematopoietic progenitor cells, cells lose their ability to mature and differentiate, proliferate in an uncontrolled manner and replace normal bone marrow.
-
True
-
False
Correct Answer
A. TrueExplanation
Acute leukemia is indeed a malignancy of the hematopoietic progenitor cells. In this condition, these cells lose their ability to mature and differentiate as they normally would. Instead, they proliferate in an uncontrolled manner and replace the normal bone marrow. This leads to an overproduction of immature white blood cells, which can be seen in the blood and bone marrow of individuals with acute leukemia. Therefore, the statement "Acute leukemia is a malignancy of the hematopoietic progenitor cells, cells lose their ability to mature and differentiate, proliferate in an uncontrolled manner and replace normal bone marrow" is true.Rate this question:

Which of the lab findings correspond to Acute lymphocytic leukemia (ALL)? A. WBC > 100,000 and Platelets < 100,00 B. WBC >200,000 C. WBC >100,000
-
A
-
B
-
C
Correct Answer
A. AExplanation
The lab findings that correspond to Acute Lymphocytic Leukemia (ALL) are a white blood cell count (WBC) greater than 100,000 and platelets less than 100,000. This combination of elevated WBC and low platelet count is commonly seen in ALL, which is a type of cancer that affects the white blood cells. The high WBC count is due to the overproduction of immature lymphocytes, while the low platelet count is a result of the bone marrow being crowded with cancerous cells, leading to a decrease in platelet production.Rate this question:

Chronic Myelogenous Leukemia (CML) has a diagnostic _______ chromosome. Treatment occurs by way of a _____ ( type of procedure).
Correct Answer
Philadelphia
Bone marrow transplantExplanation
Chronic Myelogenous Leukemia (CML) is diagnosed through the presence of the Philadelphia chromosome. This chromosome is a genetic abnormality that is found in the cancer cells of individuals with CML. The treatment for CML often involves a bone marrow transplant. This procedure replaces the diseased bone marrow with healthy bone marrow from a donor, which can help to eliminate the cancer cells and restore normal blood cell production.Rate this question:
- 24.
Acute Lymphocytic Leukemia (ALL) has a ____ onset of very high lymphocyte count, very immature malignant cells. Chronic Lymphocytic Leukemia (CLL) has a _____ onset and is often discovered on routine blood exam.
Correct Answer
Rapid
SlowExplanation
Acute Lymphocytic Leukemia (ALL) is characterized by a rapid onset, with a sudden increase in lymphocyte count and the presence of very immature malignant cells. On the other hand, Chronic Lymphocytic Leukemia (CLL) has a slow onset and is often discovered during routine blood exams, as it progresses slowly over time.Rate this question:
