PHLEBOTOMY NATIONAL EXAM (NHA)
QUESTIONS AND ANSWERS
Characteristics imperative to a phlebotomist - ANS-Dependability, honesty, integrity,
empathy and compassion, professional appearance, interpersonal skills
Circulatory system function - ANS-deliver oxygen, nutrients, hormones, & enzymes to
cells and transport cellular waste (CO2) to organs where they can be expelled
The two circulations - ANS-Pulmonary & Systemic
Pulmonary circulation - ANS-carries deoxygenated blood from the right ventricle to the
lungs and returns oxygenated blood from lungs to left atrium
Where does oxygenation take place in the lungs? - ANS-alveoli
Systemic circulation - ANS-carries oxygenated blood from left ventricle throughout the
body
Upper chambers of the heart - ANS-right and left atria
lower chambers of the heart - ANS-right and left ventricle
tricuspid valve - ANS-atrioventricular valve, situated between right atrium and right
ventricle
**to remember this valve is on the right side of the heart-- people TRY to be RIGHT
pulmonic valve - ANS-semi-lunar valve situated between the right ventricle and the
pulmonary artery
Mitral valve (or bicuspid) - ANS-atrioventricular valve located between the left atrium
and left ventricle
aortic valve - ANS-semi lunar valve situated between the left ventricle and aorta
Flow of blood through the heart - ANS-Superior and Inferior Vena Cavae< Right atrium<
tricuspid valve< right ventricle< pulmonic valve< pulmonary artery< lungs< pulmonary
vein< left atrium< mitral (bicuspid) valve< left ventricle< aorta< rest of body
Three layers of the heart - ANS-Endocardium, myocardium, epicardium
, Blood vessels - ANS-arteries, arterioles, capillaries, venules, veins, superior & inferior
vena cavae
aorta, arteries, and arterioles carry_____ blood _______ the heart - ANS-oxygenated &
away from
venules, veins, and superior and inferior vena cave carry _____ blood ________ the
heart - ANS-deoxygenated & back to
The average adult has ______ liters of blood - ANS-5-6

What percent of plasma is water? - ANS-92%
Formed elements comprise what percent of circulating blood? - ANS-45%
another name for red blood cells... - ANS-Erythrocytes
What makes up the formed elements? - ANS-Red blood cells, White blood cells, and
platelets
Another name for white blood cells... - ANS-leukocytes
another name for platelets... - ANS-thrombocytes
What comprises 99% of the formed elements? - ANS-red blood cells (erythrocytes)
Where do blood cells originate? - ANS-stem cells in bone marrow
How many RBCs are in a microliter of blood? - ANS-4.2 to 6.2 million
Normal life span of an RBS is... - ANS-120 days
Function of a leukocyte - ANS-provide the body protection against infection
Amount of WBCs per microliter of blood - ANS-5,000-10,000
leukocytosis - ANS-increase in WBCs
leukocytosis is seen when? - ANS-cases of infection and leukemia
leukopenia - ANS-decrease in WBCs
