#1
What does the term 'venipuncture' refer to in phlebotomy?
Drawing blood from a vein
ExplanationVenipuncture is the process of collecting blood by puncturing a vein, typically from the arm.
#2
Which of the following is NOT a common anticoagulant used in blood collection tubes?
Glucose
ExplanationGlucose is a sugar and not an anticoagulant. Common anticoagulants include EDTA, heparin, and sodium citrate.
#3
What is the term for the process of separating blood into its components?
Centrifugation
ExplanationCentrifugation is the process of spinning blood at high speeds to separate its components based on density, such as plasma, platelets, and red blood cells.
#4
Which blood type is considered the universal recipient?
AB
ExplanationBlood type AB is considered the universal recipient because it can receive blood from all blood types without adverse reactions.
#5
Which of the following tubes is commonly used for glucose testing?
Gray top tube
ExplanationThe gray top tube, containing sodium fluoride and potassium oxalate, is commonly used for glucose testing to inhibit glycolysis.
#6
What is the medical term for a blood clot?
Thrombosis
ExplanationA blood clot is medically termed as thrombosis, which can occur in arteries or veins.
#7
Which of the following blood components is primarily responsible for carrying oxygen?
Red blood cells
ExplanationRed blood cells, or erythrocytes, contain hemoglobin and are responsible for transporting oxygen from the lungs to tissues throughout the body.
#8
What is the medical term for the process of stopping bleeding?
Hemostasis
ExplanationHemostasis is the physiological process of stopping bleeding, involving vasoconstriction, platelet plug formation, and coagulation cascade activation.
#9
Which of the following veins is commonly used for venipuncture?
Cephalic vein
ExplanationThe cephalic vein, located in the arm, is commonly used for venipuncture due to its accessibility and minimal risk of complications.
#10
Which of the following terms refers to the process of taking blood pressure?
Sphygmomanometry
ExplanationSphygmomanometry is the medical term for measuring blood pressure using a sphygmomanometer, typically by inflating and deflating a cuff around the arm.
#11
What does 'ABO blood group' primarily determine?
Blood type
ExplanationThe ABO blood group system primarily determines an individual's blood type based on the presence or absence of antigens on red blood cells.
#12
What is the normal range for platelet count in adults?
150,000 - 400,000/µL
ExplanationThe normal range for platelet count in adults is between 150,000 and 400,000 platelets per microliter (µL) of blood.
#13
Which of the following is a term for an abnormal increase in white blood cells?
Leukocytosis
ExplanationLeukocytosis refers to an abnormal increase in the number of white blood cells in the bloodstream, often indicative of infection, inflammation, or other medical conditions.
#14
What is the term for the process of separating plasma from whole blood using centrifugation?
Serum separation
ExplanationSerum separation is the process of separating plasma from whole blood by centrifugation, resulting in a clear, cell-free liquid containing proteins, electrolytes, and other substances.
#15
Which blood component is primarily responsible for blood clotting?
Platelets
ExplanationPlatelets, or thrombocytes, are small cell fragments in the blood that play a crucial role in hemostasis and blood clotting by forming platelet plugs and releasing clotting factors.
