Phlebotomy NHA/CPT NHA
What is Hematology? - ANSW Hematology is the study of blood and its components,
fluids and cells. Also includes the study of blood forming organs and blood disease
What is Phlebotomy? - ANSW Phlebotomy is the practice of drawing blood for
diagnostic purposes
What does the medical term "Phlebos" mean? - ANSW Veins
What does the medical term "tome" mean? - ANSW Incision
What are two other names for capillary puncture? - ANSW Dermal or skin puncture
What does POC mean? - ANSW Point-of-Care
What is Point-of-Care? - ANSW Tests that can be at the patients bed side and results
can be obtained right away.
Examples: Blood Glucose, Hematocrit, Hemoglobin
What are capillaries? - ANSW Microscopic, one cell-thick vessels that connect
arterioles and venules
What is the purpose of a capillary? - ANSW Capillaries are the site of gas exchange
between blood & bodily tissues
What is the preferred locations for venipuncture? - ANSW 1. Antecubital Fossa
2. Upper aspect of the forearm
3. Posterior aspect of the wrist
4. Dorsum (back) of the hand
5. Ankle and foot veins (Dorsalis Pedis)
What does the medical term "ante" mean? - ANSW Before
What are the three superficial veins located in the Antecubital Fossa? - ANSW 1.
Median Cubital Vein: Large and fixed
2. Cephalic Vein: Preferred in obese
3. Basilic Vein: Close to the brachial artery and median nerve
What is plasma composed of? - ANSW 90% water, 7% proteins, the rest is all 1%
(proteins, amino acids, gases, electrolytes, sugars hormones, lipids & vitamins)
What color is plasma? - ANSW Straw color
, What is the difference in appearance of plasma and serum? - ANSW They both look
the same, the only way to differentiate them is by looking at the tube top color
What is the buffy coat composed of? - ANSW Leukocytes and platelets
What is the percentage of plasma in the blood by volume? - ANSW 55%
What is the percentage of formed elements? - ANSW 45%
What are formed elements? - ANSW Erythrocytes, Leukocytes, and Platelets
What do these abbreviations mean "RBCs" "WBCs"? - ANSW Red blood cells and
White blood cells
(erythrocytes and leukocytes)
Another name for thrombocytes? - ANSW Platelets
Where are erythrocytes formed? - ANSW In the red bone marrow
What is the life span of erythrocytes? - ANSW 120 days
What purpose does hemoglobin have? - ANSW It transports oxygen
What is the life span of a leukocyte? - ANSW Approximately 24 hours
What is the purpose of white blood cells? - ANSW Protect body against infection and
disease
Number of leukocytes pet cubic millimeter - ANSW 5000 - 10,000
There are two different types of white blood cells, what are they? - ANSW Granular or
Agranular leukocytes
(Granular Leukocytes - perform phagocytosis)
(Agranular Leukocytes - produce antibodies)
Fact: Granular Leukocytes are polymorphonuclear
Examples of them are: Neutrophils, Eosinophils, and Basophils
Their job is to perform Phagocytosis
They usually react to inflammation - ANSW ...
What are the differentials and their percentages? - ANSW Neutrophils: 40% - 60% -
Never
Lymphocytes: 20% - 40% - Let
Monocytes: 2% - 8% - Monkey
Eosinophils: 1% - 4% - Eat
