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 are visible under a microscope. These granules contain enzymes and proteins that are involved in the immune response, particularly in fighting off parasitic infections and allergic reactions. Eosinophils are typically identified by their bilobed nucleus and their bright red-orange granules, which can be seen in the image indicated by the arrow.Rate this question:

Tear Drop Cell (Dacroycyte)
- C.
Polychromatic RBC
- D.
Monocyte
Correct Answer
C. Polychromatic RBCExplanation
The correct answer is Polychromatic RBC. The arrow is pointing to a cell that is characterized by its varying shades of blue color, indicating that it is a polychromatic red blood cell. Polychromatic RBCs are immature red blood cells that still contain residual RNA, giving them a bluish tint. These cells are commonly seen in certain conditions such as anemia or bone marrow disorders.Rate this question:

Segmented Neutrophil
Correct Answer
D. Segmented NeutrophilExplanation
The cell identified by the arrow is a segmented neutrophil. This can be determined by comparing the characteristics of the cell with the options given. Monocytes are larger and have a kidney-shaped nucleus, lymphocytes are smaller and have a round nucleus, and basophils have large granules in the cytoplasm. The segmented neutrophil has a segmented nucleus and fine granules in the cytoplasm, which matches the characteristics of a segmented neutrophil.Rate this question:

Normal RBC
- B.
Platelet
- C.
Stomatocyte
- D.
Spherocyte
Correct Answer
D. SpherocyteExplanation
The correct answer is Spherocyte. In the given options, the arrow is pointing towards a cell that appears smaller and more condensed compared to the other cells. This indicates that it is a spherocyte, which is a type of red blood cell that is abnormally round and lacks the normal biconcave shape. Spherocytes are often associated with certain medical conditions such as autoimmune hemolytic anemia.Rate this question:

Spherocyte
- D.
Target Cell (Codocyte)
Correct Answer
A. Tear Drop Cell (Dacryocyte)Explanation
The correct answer is Tear Drop Cell (Dacryocyte). A tear drop cell, also known as a dacryocyte, is characterized by its elongated and pointed shape, resembling a tear drop. It is often associated with various hematological disorders, such as myelofibrosis and thalassemia. The arrow in the question is pointing to a cell that matches the description of a tear drop cell, indicating that it is the correct answer.Rate this question:

Normal RBC
- B.
Lymphocyte
- C.
Nucleated RBC
- D.
Pappenheimer Bodies
Correct Answer
C. Nucleated RBCExplanation
The cell identified by the arrow is a nucleated RBC. This can be determined by observing the presence of a nucleus within the cell. Normal RBCs do not have a nucleus, lymphocytes are a type of white blood cell and have a different appearance, and Pappenheimer bodies are small iron granules that can be seen within RBCs but do not have a nucleus.Rate this question:

Normal RBC
- C.
Spherocyte
- D.
Target Cell (Codocyte)
Correct Answer
B. Normal RBCExplanation
The arrow is pointing to a normal red blood cell (RBC). This can be determined by comparing the characteristics of the other options. A microcyte is a smaller than normal RBC, a spherocyte is a rounder and denser RBC, and a target cell (codocyte) has a bullseye appearance. None of these characteristics match the cell indicated by the arrow, thus it must be a normal RBC.Rate this question:

Identify the cell by the arrow.
- A.
Malarial Parasite
- B.
Normal Platelet
- C.
Giant Platelet
Correct Answer
C. Giant PlateletExplanation
The cell identified by the arrow is a giant platelet. This can be determined by comparing it to the other options provided, namely the malarial parasite and the normal platelet. The giant platelet appears larger and more irregular in shape compared to the normal platelet, indicating that it is abnormal. The malarial parasite would have a distinct appearance and would not resemble a platelet. Therefore, the cell by the arrow is most likely 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 or sausage-like shape. This can occur due to changes in the surface charge or shape of the RBCs, as well as alterations in the plasma proteins. Rouleaux formation is commonly seen in inflammatory conditions, infections, and certain diseases like multiple myeloma. It can be observed under the microscope as a characteristic pattern of RBCs sticking together. Therefore, the presence of RBCs in the given illustration suggests that the correct answer is rouleaux formation.Rate this question:
