CCI CCT EXAM
Arterioles - CORRECT ANSWERS-Small branch of an artery leading into capillaries.
Involved in the regulation of arterial blood pressure as well as blood flow within the
organ.
Arteries - CORRECT ANSWERS-Blood vessels that carry oxygen-rich blood away from
the heart
Aortic pulse pressure - CORRECT ANSWERS-systolic pressure - diastolic pressure.
The maximal change in aortic pressure during systole, from the time aortic valve opens
until peak aortic pressure is attained.
Heart size - CORRECT ANSWERS-Weighs around 250grams. 12cm in length & 8 to 9
cm in width & 6 cm thick.
blood pressure - CORRECT ANSWERS-the pressure that is exerted by the blood
against the walls of blood vessels
pulse pressure - CORRECT ANSWERS-difference between systolic and diastolic
pressure. Is regulated by by stroke volume & elasticity of arteries. Pulse pressure
indicates force of contraction of ventricles as well as flexibility of artery wall.
mean atrial pressure - Normal limit: 70 to 100 mmHg - CORRECT ANSWERS-The
pressure in the arteries during one cardiac cycle. Tells how well the vital organs are
being perfused. Mean Arterial Pressure equals Diastolic Blood Pressure times 2, plus
Systolic blood pressure, decided by 3. [MAP = 2(DBP) + SBP / 3]
blood flow - CORRECT ANSWERS-Blood enters heart through inferior and superior
vena cava emptying deoxygenated blood into right atrium. blood flows from right atrium
into right ventricle through tricuspid valve. Blood leaves heart through pulmonic valve
into pulmonary artery and lungs. Pulmonary vein carries oxygenated blood from lungs to
left atrium. Blood flows from left atrium to left ventricle through mitral valve. Blood
leaves heart through the aortic valve into aorta and to the rest of body.
, cardiac output (CO ml/min.) - CORRECT ANSWERS-The amount of blood pumped by
the heart, in one minuted. CO = HR(beats/min) * SV(ml/beat)
double product - CORRECT ANSWERS-computed by multiplying heart rate by systolic
blood pressure. (SBP *HR /100=)
Stroke volume (norm. 70 ml/beat) - CORRECT ANSWERS-Volume of blood pumped by
each ventricle with each beat. (Ml/min.)
heart rate (norm. 60 to 100 bpm) - CORRECT ANSWERS-A measure of cardiac activity
usually expressed as the number of beats per minute.
Pulse pressure equation - CORRECT ANSWERS-systolic pressure - diastolic pressure
(SBP - DBP)
systemic circulation - CORRECT ANSWERS-Carries oxygenated blood from the left
ventricle, through the arteries, to the capillaries in the tissues of the body. From the
tissue capillaries, the deoxygenated blood returns through a system of veins to the right
atrium of the heart.
The cardiac valve function - CORRECT ANSWERS-Prevent the backward flow if blood.
These valves are flaps that are located on each end of the 2 ventricles. They act as a
one-way inlets of blood on one side of the ventricle and one way outlets of the blood on
the other side of the ventricles.
4 valves, mitral and tricuspid valve, which control blood flow from the atria to the
ventricles. The aortic valve and the pulmonary valve, which control blood flow out of the
ventricles.
Unifocal PVCs - CORRECT ANSWERS-Originate from one single foci in the ventricles.
They are uniform in shape and size. Have the size and shape.
Multi-focal PVC - CORRECT ANSWERS-pattern of premature venticular contractions
originating from more than one ectopic location. Different in size and shape
Bigeminy - CORRECT ANSWERS-every other beat is a PVC
Trigeminy - CORRECT ANSWERS-every third beat is a PVC
Quadrageminy - CORRECT ANSWERS-Every fourth beat is a PVC
Bipolar leads are - CORRECT ANSWERS-Leads I, II, and III
The unipolar leads are - CORRECT ANSWERS-AVR, AVL, AVF, V1-6.
