1. Which of the following is the most abundant type of white blood cell
in a healthy adult?
A. Lymphocyte
B. Monocyte
C. Neutrophil
D. Eosinophil
Rationale: Neutrophils are the most abundant WBC in adults, typically 50–
70% of the total WBC count.
2. A patient’s hemoglobin is 7 g/dL. What is the most likely clinical
condition?
, A. Leukemia
B. Anemia
C. Polycythemia
D. Thrombocytopenia
Rationale: Hemoglobin below normal reference ranges (usually <12 g/dL in
women, <13.5 g/dL in men) indicates anemia.
3. The presence of Howell-Jolly bodies in red blood cells usually
indicates:
A. Iron deficiency
B. Functional asplenia or splenectomy
C. Lead poisoning
D. Hemolytic anemia
Rationale: Howell-Jolly bodies are nuclear remnants normally removed by
a functioning spleen; their presence indicates splenic dysfunction.
4. Which anticoagulant is commonly used for coagulation studies?
A. EDTA
B. Heparin
C. Sodium citrate
D. Oxalate
Rationale: Sodium citrate binds calcium reversibly and is preferred for PT,
aPTT, and other coagulation tests.
, 5. Which of the following enzymes is most specific for myocardial
infarction?
A. AST
B. LDH
C. Troponin I
D. CK
Rationale: Troponin I is highly specific to cardiac muscle injury and is the
preferred biomarker for myocardial infarction.
6. A serum sample is hemolyzed. Which test result is most likely to be
falsely elevated?
A. Glucose
B. Bilirubin
C. Potassium
D. Albumin
Rationale: Hemolysis releases intracellular potassium from RBCs,
artificially elevating serum potassium levels.
7. Which organism is the most common cause of urinary tract infections?
A. Staphylococcus aureus
B. Klebsiella pneumoniae
C. Escherichia coli
D. Pseudomonas aeruginosa
, Rationale: E. coli accounts for approximately 80–90% of community-
acquired UTIs.
8. The most appropriate medium for growing Neisseria gonorrhoeae is:
A. Blood agar
B. MacConkey agar
C. Thayer-Martin agar
D. Chocolate agar
Rationale: Thayer-Martin agar is selective for Neisseria gonorrhoeae and
contains antibiotics to inhibit contaminating flora.
9. Which of the following is a Gram-positive cocci in chains?
A. Staphylococcus aureus
B. Neisseria meningitidis
C. Streptococcus pyogenes
D. Enterobacter cloacae
Rationale: Streptococci are Gram-positive cocci arranged in chains, unlike
staphylococci which form clusters.
10. A patient’s WBC differential shows 70% lymphocytes and 20%
neutrophils. This is most consistent with:
A. Bacterial infection
B. Viral infection
C. Parasitic infection
D. Chronic inflammation
