CARDIOLOGY, EMTB Cardiac ACTUAL
QUESTIONS AND CORRECT ANSWERS
Coronary arteries - Correct answers✔✔Start just above the aortic valve. Supplies blood to the
right ventricle and to the inferior wall of the left ventricle.
Right and left carotid arteries - Correct answers✔✔Supply the head and brain w/ blood
Subclavian arteries - Correct answers✔✔Supply blood to upper extremities and become the
brachial arteries once they reach the arm.
Which arteries supply blood to the hands? - Correct answers✔✔Radial and ulnar arteries
What does the descending aorta branch into? - Correct answers✔✔The common iliac arteries,
which supply blood to the groin, pelvis, and legs.
The iliac becomes the ____ artery as it enters the leg thru the groin, which then becomes the
____ artery at the knee. - Correct answers✔✔Femoral; Tibial (anterior/front and posterior/back)
Which artery supplies the feet? - Correct answers✔✔The peroneal artery
Cardiac output - Correct answers✔✔Heart rate X volume of blood ejected w/ each contraction.
This is the vol of blood that passes thru the heart in 1 min/amt of blood pumped out of left
ventricle in 1 min and is the best measure of the output of the heart.
,Perfusion - Correct answers✔✔Constant flow of oxygenated blood to the tissues
Stroke volume - Correct answers✔✔Vol of blood pumped out by the left ventricle in one cardiac
cycle/with each contraction. It's affected by preload, afterload, and contractility. Preload is
related to venous return to the rt atrium. Afterload is associated w/ systemicc vascular resistance,
which is a function of the constriction of the systemic bv's. Contractility refers to how forcefully
the heart contracts.
Ischemia - Correct answers✔✔Insufficient O2 supply that deprives tissues of nutrients, resulting
from partial blockage of blood flow; potentially reversible.
Lumen - Correct answers✔✔Inside diameter of an artery or other hollow structure
Infarction - Correct answers✔✔Tissue death
V-fib - Correct answers✔✔Disorganized, ineffective twitching of the ventricles, resulting in no
blood flow and a state of cardiac arrest.
V-tach - Correct answers✔✔Rapid heart rhythm in which electrical impulse begins in the
ventricle instead of the atrium, which may result in inadequate blood flow and eventually
deteriorate into cardiac arrest.
Cardiac Arrest Treatment - Correct answers✔✔Rapid CPR and early application of an AED.
Maintain open airway, apply high concentration of oxygen, non rebreather mask.
Dyspnea - Correct answers✔✔Shortness of breath, labored or difficulty breathing.
, AED Indications - Correct answers✔✔Pulseless
Not Breathing
Unresponsive
AED Use - Correct answers✔✔AED says "analyzing" do not touch patient.
Chest Pain - Correct answers✔✔Administer Oxygen
AED Shockable Rhythms - Correct answers✔✔V-Tach
V-Fib
Acute Myocardial Infarction - Correct answers✔✔Often called a Heart Attack. The condition in
which a portion of the myocardium dies as a result of oxygen starvation.
Best known heart problem symptom - Correct answers✔✔Chest Pain
AED Single Shock - Correct answers✔✔After a single shock from an AED, and patient regains
pulse, place patient in recovery position.
Coronary Arteries - Correct answers✔✔Blood vessels that supply the myocardium
Congestive Heart Failure - Correct answers✔✔Congestive Heart Failure is often a complication
with a heart attack.
Cardiogenic Shock - Correct answers✔✔Shock or lack of perfusion brought on by inadequate
pumping action of the heart.
