What is spectrophotometry used for in clinical chemistry? - correct answer -To measure the absorption
of light by a chemical substance to determine its concentration.
What is the Beer-Lambert Law? - correct answer -It states that the absorbance of light is directly
proportional to the concentration of the absorbing substance in a solution.
What is the principle behind electrophoresis? - correct answer -It separates molecules (e.g., proteins,
DNA) based on their size and charge using an electric field.
What is the difference between end-point and kinetic reactions in clinical chemistry? - correct answer -
End-point reactions measure the final product after the reaction is complete, while kinetic reactions
measure the rate of change during the reaction.
What information is required for positive patient identification? - correct answer -Name, medical
record number, date of birth, and other unique identifiers.
What is a sentinel event in blood banking? - correct answer -A serious error, such as mislabeling a
blood sample, that could lead to patient harm.
What is waived testing? - correct answer -Simple laboratory tests that are exempt from CLIA
regulations due to their low risk of error.
What is an example of a waived test? - correct answer -Urine dipstick tests, glucose monitoring, and
pregnancy tests.
What is the purpose of linearity in quality control? - correct answer -To ensure that an instrument
provides accurate results across a range of concentrations.
,What is the coefficient of variation (CV) used for? - correct answer -To measure the precision of a test
by comparing the standard deviation to the mean.
What is a shift in quality control data? - correct answer -A consistent deviation of results from the
mean, indicating a systematic error.
What is a trend in quality control data? - correct answer -A gradual increase or decrease in results over
time, indicating a potential issue with the instrument or reagents.
What is the purpose of a chemical spill kit? - correct answer -To safely clean up and neutralize chemical
spills in the laboratory.
What is the proper way to handle a biohazard spill? - correct answer -Wear PPE, contain the spill,
disinfect with an appropriate solution, and dispose of materials in a biohazard container.
What is the purpose of a pipette in the laboratory? - correct answer -To accurately measure and
transfer small volumes of liquid.
What is the proper way to clean glassware in the laboratory? - correct answer -Rinse with distilled
water, clean with detergent, rinse again, and dry or autoclave if necessary.
What is the purpose of a balance in the laboratory? - correct answer -To measure the mass of
substances with high precision.
What is the formula for calculating a percentage solution (w/v)? - correct answer -(Weight of solute in
grams / Volume of solution in mL) × 100.
What is the formula for calculating a dilution factor? - correct answer -Dilution factor = (Final volume) /
(Volume of stock solution).
,What is the equivalent weight of a substance? - correct answer -The mass of a substance that reacts
with or supplies one mole of hydrogen ions (H⁺) or electrons.
What is the purpose of the condenser in a microscope? - correct answer -To focus light onto the
specimen for better illumination.
What is the proper way to calibrate an ocular micrometer? - correct answer -Use a stage micrometer
to determine the conversion factor for the ocular micrometer.
What is the purpose of a glucose tolerance test? - correct answer -To evaluate how the body processes
glucose over time, often used to diagnose diabetes.
What is the proper way to handle irretrievable specimens (e.g., CSF, tissue)? - correct answer -Process
them immediately or preserve them according to laboratory protocols to prevent degradation.
What is the significance of hemolysis in blood samples? - correct answer -Hemolysis can interfere with
test results, particularly for potassium, LDH, and other analytes.
What is the purpose of a STAT test? - correct answer -To prioritize urgent tests that require immediate
results for patient care.
What is the significance of a call report in laboratory testing? - correct answer -It ensures that critical
results are communicated to healthcare providers promptly.
What is the difference between waived and non-waived tests? - correct answer -Waived tests are
simple and low-risk, while non-waived tests require more complex procedures and are subject to stricter
regulations.
What is the function of red blood cells (RBCs)? - correct answer -To transport oxygen from the lungs to
tissues and carbon dioxide from tissues to the lungs.
, What is the function of white blood cells (WBCs)? - correct answer -To defend the body against
infections and foreign substances.
What is the function of platelets (thrombocytes)? - correct answer -To assist in blood clotting and
wound healing.
What is hematopoiesis? - correct answer -The process of blood cell formation, occurring primarily in
the bone marrow.
What is the normal range for hemoglobin (HGB) in adult males? - correct answer -13.8-17.2 g/dL.
What is the normal range for hematocrit (HCT) in adult females? - correct answer -36-46%.
What is the significance of the red cell distribution width (RDW)? - correct answer -It measures the
variation in red blood cell size, indicating anisocytosis.
What is the formula for calculating mean corpuscular volume (MCV)? - correct answer -MCV =
(Hematocrit / RBC count) × 10.
What is the formula for calculating mean corpuscular hemoglobin (MCH)? - correct answer -MCH =
(Hemoglobin / RBC count) × 10.
What is the formula for calculating mean corpuscular hemoglobin concentration (MCHC)? - correct
answer -MCHC = (Hemoglobin / Hematocrit) × 100.
What is the significance of a high reticulocyte count? - correct answer -It indicates increased red blood
cell production, often seen in hemolytic anemia or after blood loss.
What is the purpose of the erythrocyte sedimentation rate (ESR)? - correct answer -To measure the
rate at which red blood cells settle in a tube, indicating inflammation or infection.
