Trivia Quiz On Hematology Competency Assessment!
Cells are the building blocks of all living things, and this goes without saying that the blood is made up of various cells. Do you know which cells are an anomaly, and which ones are not? Below is a trivia quiz on hematology competency assessment, which is designed to be used with clinical laboratory staff to assess their competency in Hematology, in conjunction with observations and checklists, to satisfy regulatory requirements.
- 1.
Identify the cell by the arrow. Pay attention to the granules.
- A.
Basophil
- B.
Eosinophil
- C.
Lymphocyte
- D.
Monocyte
Correct Answer
B. EosinophilExplanation
The correct answer is Eosinophil. Eosinophils are a type of white blood cell that are characterized by their granules, which can be seen in the image. They are involved in the immune response against parasites and are also associated with allergic reactions. Their granules contain enzymes that help to destroy pathogens and regulate inflammation.Rate this question:

Basophil
- B.
Eosinophil
- C.
Lymphocyte
- D.
Monocyte
Correct Answer
A. BasophilExplanation
The cell identified by the arrow is a basophil. Basophils are a type of white blood cell that are involved in allergic reactions and the immune response to parasites. They contain granules filled with histamine and other chemicals that are released during an allergic response, causing inflammation and other symptoms. Basophils are also involved in the regulation of immune responses and play a role in certain autoimmune diseases.Rate this question:

Ovalocytes or Elliptocyte
- C.
Dacryocyte (tear drop cell)
- D.
Shistocyte (red cell fragment)

Shistocyte
- B.
Tear Drop Cell (Dacroycyte)
- C.
Polychromatic RBC
- D.
Monocyte
Correct Answer
C. Polychromatic RBCExplanation
The correct answer is Polychromatic RBC. A polychromatic RBC is a type of red blood cell that appears bluish-purple due to the presence of both mature and immature red blood cells. In the given options, the arrow is pointing towards a cell that has a bluish-purple color, indicating that it is a polychromatic RBC. The other options, such as schistocyte, tear drop cell, and monocyte, do not match the appearance of the cell indicated by the arrow.Rate this question:

Identify the cell by the arrow.
- A.
Lymph
- B.
Monocyte
- C.
Basophil
- D.
Plasma Cell
Correct Answer
B. MonocyteExplanation
The correct answer is Monocyte because it is the only cell type mentioned in the given options that can be identified by the arrow. Lymph, Basophil, and Plasma Cell are not indicated by the arrow, so they cannot be the correct answer.Rate this question:

Segmented Neutrophil
Correct Answer
D. Segmented NeutrophilExplanation
The arrow is pointing to the cell labeled "Segmented Neutrophil."Rate this question:

Identify the cell by the arrow.
- A.
Normal RBC
- B.
Platelet
- C.
Stomatocyte
- D.
Spherocyte
Correct Answer
D. SpherocyteExplanation
The cell identified by the arrow is a spherocyte. This can be determined based on its shape, which appears round and smaller in size compared to the other options. Spherocytes are abnormally shaped red blood cells that lack the usual concave shape and appear more spherical. They are commonly associated with certain medical conditions, such as autoimmune hemolytic anemia.Rate this question:

- A.
Tear Drop Cell (Dacryocyte)
- B.
Rouleaux
- C.
Spherocyte
- D.
Target Cell (Codocyte)
Correct Answer
A. Tear Drop Cell (Dacryocyte)Explanation
The correct answer is Tear Drop Cell (Dacryocyte). Based on the given options, the cell identified by the arrow is a tear drop-shaped cell, also known as a dacryocyte. Dacryocytes are abnormal red blood cells that can be seen in certain blood disorders, such as myelofibrosis or thalassemia. These cells have a characteristic shape with a pointed end, resembling a tear drop. This abnormal shape is caused by the bone marrow's inability to produce red blood cells properly, leading to the formation of misshapen cells.Rate this question:

Identify the cell by the arrow.
- A.
Normal RBC
- B.
Lymphocyte
- C.
Nucleated RBC
- D.
Pappenheimer Bodies
Correct Answer
C. Nucleated RBCExplanation
The cell indicated by the arrow is a nucleated red blood cell. This can be determined by the presence of a nucleus within the cell, which is not typically seen in normal red blood cells. Nucleated red blood cells are often associated with certain medical conditions or disorders, and their presence can indicate an abnormality in the blood.Rate this question:

Identify the cell by the arrow.
- A.
Platelet, normal
- B.
Platelet, Giant
- C.
Cellular Debris
- D.
NRBC
Correct Answer
A. Platelet, normalExplanation
The correct answer is Platelet, normal. This is because the arrow is pointing to a cell that has a small, round shape with granules in the cytoplasm, which is characteristic of platelets. Platelets are important for blood clotting and are typically small in size. The other options, such as Platelet, Giant, Cellular Debris, and NRBC, do not match the characteristics of the cell pointed by the arrow.Rate this question:

Identify the cell by the arrow.
- A.
Microcyte
- B.
Normal RBC
- C.
Spherocyte
- D.
Target Cell (Codocyte)
Correct Answer
B. Normal RBCExplanation
The cell identified by the arrow is a normal red blood cell (RBC). This can be determined by its appearance, which does not show any abnormalities or deformities commonly associated with microcytes, spherocytes, or target cells. Therefore, the correct answer is Normal RBC.Rate this question:
-
- 13.
Identify the cell by the arrow.
- A.
Malarial Parasite
- B.
Normal Platelet
- C.
Giant Platelet
Correct Answer
C. Giant PlateletExplanation
The correct answer is "Giant Platelet" because the arrow is pointing towards a cell that is larger in size compared to the other two options. This suggests that it is a giant platelet, which is a condition characterized by abnormally large platelets in the blood. Malarial parasites are not typically represented by a single cell, and normal platelets are smaller in size. Therefore, the arrow is indicating the presence of a giant platelet.Rate this question:

The RBC found in below illustration are the result of:
- A.
Rouleux formation
- B.
Micro agglutination
- C.
Over drying of blood smear
- D.
Cold agglutinin
Correct Answer
A. Rouleux formationExplanation
Rouleaux formation refers to the stacking or clumping of red blood cells (RBCs) in a linear arrangement, resembling a stack of coins. This phenomenon occurs due to the presence of certain proteins or molecules on the surface of RBCs that cause them to adhere to each other. Rouleaux formation can be observed in conditions such as inflammation, infections, and certain diseases. Therefore, the RBCs seen in the illustration are the result of rouleaux formation, where the RBCs have clumped together in a linear pattern.Rate this question:
