1. Question 1

   A patient with suspected pheochromocytoma should be tested for:

   1. AAldosterone
   2. BCortisol
   3. CPlasma metanephrines
   4. DACTH
   Show answer

   Answer: C. Plasma metanephrines

   Plasma metanephrines are sensitive markers for catecholamine-secreting tumors. SLLE tests tumor marker selection.

2. Question 2

   In patient safety systems, “safety culture” mainly refers to:

   1. AStaff training
   2. BIncident punishment
   3. CSafety reporting system
   4. DEquipment monitoring
   Show answer

   Answer: C. Safety reporting system

   A safety culture promotes reporting errors to improve systems, not blame individuals.

3. Question 3

   Which test evaluates platelet function and capillary integrity?

   1. AProthrombin time
   2. BThrombin time
   3. CBleeding time
   4. DClotting time
   Show answer

   Answer: C. Bleeding time

   Bleeding time reflects platelet function and capillary integrity. Coagulation times assess clotting factors, not platelets. Common mistakes: assuming all bleeding tests assess coagulation pathways.

4. Question 4

   Listeria monocytogenes is best described as:

   1. AGram-positive spore-forming rod
   2. BGram-positive non-spore-forming rod
   3. CGram-negative cocci
   4. DGram-negative spore-forming rod
   Show answer

   Answer: B. Gram-positive non-spore-forming rod

   Listeria is a Gram-positive, non-spore-forming rod. A frequent mistake is confusing it with Bacillus, which forms spores.

5. Question 5

   Which complement component is primarily responsible for chemotaxis of neutrophils?

   1. AC3b
   2. BC4
   3. CC5a
   4. DMAC
   Show answer

   Answer: C. C5a

   C5a is a powerful chemotactic factor that attracts neutrophils to sites of infection and inflammation. While C3b is important for opsonization and MAC causes cell lysis, chemotaxis is specifically driven by C5a. Common mistakes: choosing C3b because it is frequently mentioned in immunity, or MAC due to its destructive role rather than signaling function.

6. Question 6

   A biopsy specimen intended for histopathological examination is accidentally placed in saline instead of the correct fixative. Which issue is MOST likely to occur?

   1. ALoss of antigenicity only
   2. BAutolysis and poor tissue preservation
   3. CExcessive dehydration
   4. DOverfixation artifact
   Show answer

   Answer: B. Autolysis and poor tissue preservation

   Formalin preserves tissue by cross-linking proteins and preventing autolysis. Saline does not stop enzymatic degradation. Improper fixation compromises histological interpretation. SLLE often tests consequences of incorrect specimen handling.

7. Question 7

   A donor presents with active skin lesions. What is the appropriate action?

   1. AAccept donation
   2. BDefer permanently
   3. CSend to physician
   4. DCollect plasma only
   Show answer

   Answer: C. Send to physician

   Skin lesions may indicate infection; medical evaluation is required before donation.

8. Question 8

   Which sterilization method uses Bacillus stearothermophilus as a biological indicator?

   1. ADry heat
   2. BEthylene oxide
   3. CAutoclave
   4. DGamma radiation
   Show answer

   Answer: C. Autoclave

   Bacillus stearothermophilus spores are used to monitor autoclave effectiveness. Confusion arises with Bacillus subtilis, which is for dry heat.

9. Question 9

   Presence of ketones in urine indicates:

   1. AExcess glucose intake
   2. BFatty acid utilization
   3. CRenal failure
   4. DLiver disease
   Show answer

   Answer: B. Fatty acid utilization

   Ketones form when cells use fat instead of glucose, often due to insulin deficiency.

10. Question 10

    Which RBC abnormality is associated with hereditary spherocytosis?

    1. ATarget cells
    2. BSchistocytes
    3. CSpherocytes
    4. DTear drop cells
    Show answer

    Answer: C. Spherocytes

    Spherocytes result from membrane protein defects. Common mistakes: choosing schistocytes, which indicate mechanical destruction.
