Which practice is most important when collecting ascitic fluid for diagnostic testing?
A. Using a non-sterile needle
B. Collecting the fluid from multiple sites
C. Allowing the fluid to clot before analysis
D. Following aseptic technique
D
Explanation: Aseptic technique prevents contamination and ensures that the ascitic fluid
remains suitable for accurate diagnostic testing.
What is the recommended method for handling cerebrospinal fluid (CSF) specimens?
A. Vigorous shaking to mix the contents
B. Minimal agitation and immediate transport
C. Freezing immediately upon collection
D. Exposure to light to enhance visibility
, Page 2 of 110
B
Explanation: Minimal agitation and prompt transport preserve the cellular and chemical
integrity of CSF specimens.
How does proper temperature control during the transport of other fluids benefit laboratory
analysis?
A. It speeds up bacterial growth
B. It prevents degradation of sensitive components
C. It changes the fluid's viscosity
D. It enhances fluid color
B
Explanation: Temperature control prevents the degradation of analytes and preserves the
specimen's quality for accurate analysis.
Which step is critical when processing synovial fluid specimens?
A. Immediate transfer to a sterile container and prompt analysis
B. Allowing the fluid to stand for several hours
C. Mixing with blood to enhance viscosity
D. Exposing the fluid to high temperatures
A
Explanation: Prompt and sterile handling of synovial fluid ensures that its diagnostic properties
are maintained

What precaution should be taken when collecting pericardial fluid?
A. Avoiding the use of a sterile field
B. Mixing the fluid with saline
C. Collecting in a non-sealed container
D. Using aseptic techniques to prevent infection
D
Explanation: Aseptic technique is essential during collection to prevent infection and ensure the
integrity of the pericardial fluid.
Which anticoagulant is most commonly used in blood specimen collection for coagulation
studies?
A. EDTA
B. Sodium Citrate
C. Heparin
D. Lithium Heparin
B
Explanation: Sodium Citrate binds calcium ions, which are necessary for blood clotting, making
it ideal for coagulation studies.
What is the primary purpose of gently inverting a blood collection tube immediately after
specimen collection?
, Page 4 of 110
A. To mix the blood with additives
B. To enhance clot formation
C. To cool the sample
D. To remove air bubbles
A
Explanation: Gentle inversion mixes the blood with the anticoagulant or additives evenly,
preventing clotting without causing hemolysis.
Which technique is essential to minimize hemolysis during blood specimen collection?
A. Using a small gauge needle
B. Forcing rapid blood draw
C. Gentle venipuncture and smooth handling
D. Shaking the tube vigorously
C
Explanation: A gentle venipuncture technique and careful handling reduce the risk of red blood
cell rupture (hemolysis).
In blood specimen handling, why is it critical to avoid prolonged tourniquet application?
A. It increases the blood flow
B. It may lead to hemoconcentration
C. It sterilizes the vein
D. It enhances anticoagulant action
