1. Question:
Which of the following laboratory tests is primarily used to monitor anticoagulant
therapy?
A. Complete Blood Count (CBC)
B. Prothrombin Time (PT)
C. Basic Metabolic Panel (BMP)
D. Thyroid Function Tests
Answer: B. Prothrombin Time (PT)
Rationale: Prothrombin Time (PT) is a test that measures how long it takes for blood to clot
and is primarily used to monitor patients on anticoagulant therapy, such as warfarin.
2. Question:
In blood banking, which type of blood component is preferred for a patient with severe
thrombocytopenia?
A. Whole Blood
B. Fresh Frozen Plasma (FFP)
C. Platelet Concentrate
D. Packed Red Blood Cells (PRBC)
Answer: C. Platelet Concentrate
Rationale: Platelet concentrate is specifically used to treat severe thrombocytopenia, as it
directly increases the platelet count in the patient.
3. Question:
What is the principle of the ELISA test?
A. Enzyme-linked immunosorbent assay detects antibodies or antigens in a
sample.
B. A cytological examination to detect malignant cells.
C. A method for measuring glucose levels in blood.
D. A culture method for isolating bacteria.
,Answer: A. Enzyme-linked immunosorbent assay detects antibodies or antigens in a
sample.
Rationale: ELISA (Enzyme-Linked Immunosorbent Assay) is a common laboratory
technique used to detect and quantify proteins, antibodies, or hormones in a sample by
utilizing enzyme-linked antibodies.
4. Question:
Which laboratory test is most useful for diagnosing acute kidney injury?
A. Serum Creatinine
B. Serum Albumin
C. Blood Urea Nitrogen (BUN)
D. Urinalysis
Answer: A. Serum Creatinine
Rationale: Serum creatinine is a key indicator of kidney function and is commonly used to
assess for acute kidney injury. An increase in serum creatinine levels typically indicates
impaired kidney function.
5. Question:
What is the purpose of performing a differential white blood cell count?
A. To determine blood type
B. To assess hemoglobin levels
C. To identify the specific types of white blood cells present in the blood
D. To check for coagulation abnormalities
Answer: C. To identify the specific types of white blood cells present in the blood
Rationale: A differential white blood cell count identifies the proportion of different types of
leukocytes in the blood, which can help diagnose various conditions, including infections and
hematologic disorders.
6. Question:
Which of the following is a common cause of hemolysis in a blood sample?
A. Delayed processing of the sample
B. Use of a tourniquet for more than one minute
C. Collection of the sample from a fingerstick
, D. All of the above
Answer: D. All of the above
Rationale: Each of these factors can contribute to hemolysis of a blood sample, leading to
inaccurate laboratory results.
7. Question:
What is the significance of the reticulocyte count in a clinical setting?
A. It assesses the body's response to anemia.
B. It measures the concentration of platelets.
C. It detects the presence of immature red blood cells.
D. It evaluates coagulation factors.
Answer: A. It assesses the body's response to anemia.
Rationale: The reticulocyte count indicates how well the bone marrow is responding to
anemia by producing new red blood cells. An increased reticulocyte count suggests active
erythropoiesis.
8. Question:
Which of the following tests is typically included in a comprehensive metabolic panel
(CMP)?
A. Blood glucose
B. Lipase
C. Troponin
D. Prothrombin time
Answer: A. Blood glucose
Rationale: A comprehensive metabolic panel (CMP) includes tests for glucose, electrolytes,
kidney function, and liver function, among others. Blood glucose is a standard component of
the CMP.
9. Question:
Which type of specimen is required for a culture and sensitivity test?
A. Serum
B. Urine
, C. Tissue biopsy
D. All of the above
Answer: D. All of the above
Rationale: Culture and sensitivity tests can be performed on various types of specimens,
including serum, urine, and tissue biopsy, to identify infectious agents and determine their
susceptibility to antibiotics.
10. Question:
What is the primary method used for the quantitative determination of blood glucose?
A. Colorimetry
B. High-Performance Liquid Chromatography (HPLC)
C. Enzymatic method
D. Immunoassay
Answer: C. Enzymatic method
Rationale: The enzymatic method is the primary method for quantitatively determining
blood glucose levels. This method uses specific enzymes to produce a measurable product
that correlates with glucose concentration.
11. Question:
Which coagulation factor is absent in hemophilia A?
A. Factor II
B. Factor VII
C. Factor VIII
D. Factor IX
Answer: C. Factor VIII
Rationale: Hemophilia A is characterized by a deficiency in Factor VIII, which is crucial for
blood clotting.
12. Question:
What is the normal range for adult serum potassium levels?
A. 2.5-4.5 mEq/L
