COMPREHENSIVE EXAM STUDY GUIDE
⩥ Which arteries supply blood to the hands? Answer: Radial and ulnar
arteries
⩥ What does the descending aorta branch into? Answer: 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? Answer: Femoral;
Tibial (anterior/front and posterior/back)
⩥ Which artery supplies the feet? Answer: The peroneal artery
⩥ Cardiac output. Answer: 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. Answer: Constant flow of oxygenated blood to the tissues
,⩥ Stroke volume. Answer: 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. Answer: Insufficient O2 supply that deprives tissues of
nutrients, resulting from partial blockage of blood flow; potentially
reversible.
⩥ Lumen. Answer: Inside diameter of an artery or other hollow structure
⩥ Infarction. Answer: Tissue death
⩥ V-fib. Answer: Disorganized, ineffective twitching of the ventricles,
resulting in no blood flow and a state of cardiac arrest.
⩥ V-tach. Answer: 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. Answer: Rapid CPR and early application
of an AED.
, Maintain open airway, apply high concentration of oxygen, non
rebreather mask.
⩥ Dyspnea. Answer: Shortness of breath, labored or difficulty breathing.
⩥ AED Indications. Answer: Pulseless
Not Breathing
Unresponsive
⩥ AED Use. Answer: AED says "analyzing" do not touch patient.
⩥ Chest Pain. Answer: Administer Oxygen
⩥ AED Shockable Rhythms. Answer: V-Tach
V-Fib
⩥ Acute Myocardial Infarction. Answer: 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. Answer: Chest Pain
