What is the stain of choice for a Differential WBC count?
-
Giemsa
-
Supravital
-
Wright's
-
All of the above
Correct Answer
A. Wright'sExplanation
Wright's stain is the stain of choice for a Differential WBC count. It is commonly used in laboratories to differentiate and identify different types of white blood cells. Wright's stain allows for the visualization of the cellular morphology and staining characteristics of the white blood cells, aiding in the identification and quantification of different cell types. Giemsa and supravital stains are not specifically used for differential WBC counts, making Wright's stain the correct answer.Rate this question:

You evaluate a smear and notice that all of the cells appear too blue. How would you classify the staining technique?
-
Good stain
-
Alkaline stain
-
Acid stain
-
Basic stain
Correct Answer
A. Alkaline stainExplanation
An alkaline stain is a staining technique that results in cells appearing too blue. This suggests that the stain used has a high pH, causing the cells to take up more of the basic dye and appear more blue in color.Rate this question:

What is the anticoagulant of choice for performing a reticulocyte?
-
EDTA
-
Sodium Heparin
-
Lithium Heparin
-
CPDA-1
Correct Answer
A. EDTAExplanation
EDTA is the anticoagulant of choice for performing a reticulocyte count because it prevents clotting by chelating calcium ions, which are necessary for the coagulation cascade. This allows for accurate measurement of reticulocytes, which are immature red blood cells. Sodium heparin and lithium heparin are also commonly used anticoagulants, but they may interfere with the staining process used to identify reticulocytes. CPDA-1 is an anticoagulant used for preserving whole blood for transfusion and is not suitable for reticulocyte counting.Rate this question:

Identify this cell that circulates within the peripheral blood and is utilized in determining the success of a bone marrow transplant.
-
Heinz body
-
Reticulocyte
-
Pappenheimer body
-
None of the above
Correct Answer
A. ReticulocyteExplanation
A reticulocyte is a cell that circulates within the peripheral blood and is used to determine the success of a bone marrow transplant. Reticulocytes are immature red blood cells that still contain remnants of ribosomes, giving them a reticular or lace-like appearance when stained. After a bone marrow transplant, the number of reticulocytes in the blood can be measured to assess the functionality of the transplanted bone marrow and the production of new red blood cells. Therefore, the presence and count of reticulocytes are crucial in evaluating the success of a bone marrow transplant.Rate this question:

The Differential White Blood Cell Count test is performed to diagnose what? (select that apply)
-
Infection
-
Anemia
-
Cancer
Correct Answer(s)
A. Infection
A. CancerExplanation
A Differential White Blood Cell Count Test is performed to diagnose the following:
Infection: This test helps identify infections by measuring the different types of white blood cells. Elevated levels of certain types of white cells can indicate an infection.
Cancer: Certain cancers, like leukemia, can be detected through abnormal white blood cell counts and distributions.Rate this question:

What could be the reason for increased neutrophils?
-
Acute infection
-
Acute stress
-
Trauma
-
All of the above
Correct Answer
A. All of the aboveExplanation
Neutrophils are a type of white blood cell that plays a crucial role in the immune response against infections. When there is an acute infection, the body increases the production and release of neutrophils to combat the invading pathogens. Acute stress can also trigger the release of neutrophils as part of the body's fight or flight response. Similarly, trauma or injury can cause an increase in neutrophils as the body initiates an inflammatory response to heal the damaged tissues. Therefore, all of the above factors can contribute to an increased number of neutrophils.Rate this question:

What could be the reason for decreased neutrophils?
-
Flu
-
Bacterial infection
-
Viral infection
-
All of the above
Correct Answer
A. All of the aboveExplanation
The reason for decreased neutrophils could be all of the above options, including flu, bacterial infection, and viral infection. Neutrophils are a type of white blood cell that play a crucial role in fighting off infections. During an infection, the body's immune response may cause a decrease in the number of neutrophils. This can occur in response to various types of infections, including the flu, bacterial infections, and viral infections. Therefore, all of the listed options can lead to a decrease in neutrophil count.Rate this question:

White blood cell differential is the blood test performed with a complete blood count.
-
True
-
False
Correct Answer
A. TrueExplanation
The explanation for the given correct answer is that a white blood cell differential is indeed a blood test that is performed along with a complete blood count. This test helps to determine the different types and percentages of white blood cells present in the blood sample. It provides valuable information about the immune system and can help in diagnosing various infections, allergies, and other medical conditions. Therefore, the statement "White blood cell differential is the blood test performed with a complete blood count" is true.Rate this question:

There are 8 types of white blood cells.
-
True
-
False
Correct Answer
A. FalseExplanation
The statement "There are 8 types of white blood cells" is false. In reality, there are five main types of white blood cells: neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Each type of white blood cell has a different function in the immune system.Rate this question:
