1. What is the primary role of a Pathologists’ Assistant in a
pathology laboratory?
A. Diagnosing diseases independently
B. Assisting in surgical procedures
C. Performing gross examination and dissection of specimens
D. Prescribing medications
Rationale: Pathologists’ Assistants mainly handle the gross
examination and preparation of surgical specimens for
microscopic analysis.
Correct Answer: C. Performing gross examination and
dissection of specimens
2. Which fixative is most commonly used for preserving tissue
specimens in pathology laboratories?
A. Methanol
B. Ethanol
C. Formalin
D. Acetone
Rationale: 10% neutral buffered formalin is widely used
because it preserves tissue structure effectively for histological
,examination.
Correct Answer: C. Formalin
3. The process of embedding tissue in paraffin is primarily
done to:
A. Preserve DNA
B. Harden tissue for sectioning
C. Increase tissue size
D. Sterilize tissue
Rationale: Paraffin embedding provides a firm medium
allowing tissues to be cut into thin sections for microscopy.
Correct Answer: B. Harden tissue for sectioning
4. Which instrument is commonly used to cut thin sections of
tissue embedded in paraffin?
A. Microtome
B. Cryostat
C. Scalpel
D. Centrifuge
Rationale: A microtome cuts tissue sections typically between
3–5 micrometers thick.
Correct Answer: A. Microtome
,5. The staining method most commonly used for routine
histology is:
A. Gram stain
B. Hematoxylin and eosin stain
C. Ziehl–Neelsen stain
D. Silver stain
Rationale: Hematoxylin and eosin (H&E) is the standard stain
used to visualize tissue structure.
Correct Answer: B. Hematoxylin and eosin stain
6. Which organ is primarily responsible for detoxification and
metabolism in the body?
A. Kidney
B. Liver
C. Pancreas
D. Spleen
Rationale: The liver processes toxins, drugs, and metabolic
products.
Correct Answer: B. Liver
7. In pathology specimen handling, “grossing” refers to:
A. Microscopic examination
B. Recording specimen weight and measurements
, C. Dissection and description of the specimen
D. DNA sequencing
Rationale: Grossing includes examining, measuring, describing,
and dissecting tissue specimens before microscopic analysis.
Correct Answer: C. Dissection and description of the specimen
8. Which safety practice is essential when handling formalin?
A. Drinking water immediately afterward
B. Using personal protective equipment (PPE)
C. Heating the solution
D. Storing it in open containers
Rationale: Formalin is toxic and requires proper PPE such as
gloves, masks, and lab coats.
Correct Answer: B. Using personal protective equipment (PPE)
9. Frozen section analysis is primarily used to:
A. Preserve tissue permanently
B. Provide rapid diagnosis during surgery
C. Detect viral DNA
D. Determine blood group
Rationale: Frozen sections allow pathologists to give rapid
intraoperative diagnoses.
Correct Answer: B. Provide rapid diagnosis during surgery
