,1. Which of the following anticoagulants is commonly used for
coagulation studies?
A. EDTA
B. Sodium citrate
C. Heparin
D. Potassium oxalate
Rationale: Sodium citrate binds calcium reversibly, preserving
clotting factors for coagulation assays.
2. The most common cause of a false-negative blood culture result is:
A. Contamination
, B. Prior antibiotic therapy
C. Poor technique
D. Hemolysis
Rationale: Antibiotics can suppress bacterial growth, leading to false-
negative results.
3. What is the reference range for adult hemoglobin (Hb)?
A. 8–12 g/dL
B. 10–14 g/dL
C. 12–16 g/dL
D. 14–18 g/dL
Rationale: Normal adult hemoglobin levels are generally 12–16 g/dL
for females and 14–18 g/dL for males.
4. Which test is used to monitor long-term glucose control in diabetic
patients?
A. Fasting glucose
B. Oral glucose tolerance test
C. Random glucose
D. Hemoglobin A1c
Rationale: Hemoglobin A1c reflects average blood glucose over the
past 2–3 months.
5. A blood smear shows microcytic, hypochromic RBCs. The most likely
cause is:
A. Vitamin B12 deficiency
, B. Iron deficiency anemia
C. Aplastic anemia
D. Hemolytic anemia
Rationale: Iron deficiency leads to smaller, paler red cells due to
impaired hemoglobin synthesis.
6. Which microorganism is most commonly associated with urinary tract
infections?
A. Staphylococcus aureus
B. Streptococcus pyogenes
C. Escherichia coli
D. Pseudomonas aeruginosa
Rationale: E. coli accounts for approximately 80% of uncomplicated
UTIs.
7. Which type of white blood cell increases primarily during allergic
reactions?
A. Neutrophils
B. Lymphocytes
C. Eosinophils
D. Monocytes
Rationale: Eosinophils play a key role in allergic and parasitic
responses.
8. A patient’s potassium level is 6.2 mEq/L. This condition is called:
A. Hypokalemia
