after how many minutes without blood flow, would the brain cells be considered irreversible
1-2 minutes
2-3 minutes
3-4 minutes
4-5 minutes
the correct sequence for impulses traveling thru the conduction sytem is
av node, bundle of his, sa node, purkinje fibers
purkinje fibers, av node, sa node, bundle of his
sa node, av node, bundle of his, purkinje fibers
sa node, bundle of his, av node, purkinje fibers
which is considered the "pacemaker" of the heart
av node
bundle of his
sa node
purkinje fibers
the sa node sends an electrical impulse to the atria causing them to
stop
depolarize
repolarize
relax
what causes a heart murmur
abnormal conduction of the SA node
abnormal heart sound due to improper closing of a valve
abnormal heart sound due to improper contraction of the atrium
change in heart rate due to changes in breathing
which of the following contains oxygenated blood?
aorta
inferior vena cava
pulmonary artery
right ventricle
as the ventricle contract,
blood moves into the atria
the bicuspid/tricuspid valves close, blood moves to atria
the atria contract
the bicuspid and tricuspid valves close
if a patient's heart rate is 100 and 60 ml of blood is expelled with each contraction, what is his cardiac output
40 ml/minute
60 ml/minute
160 ml/minute
600 ml/minute
6000 ml/minute
the condition in which many area of the heart contract rapidly and at random is called
angina pectoria
debrillation
fibrillation
premature ventricular contraction
Mr. Jones is admitted to ICU with a myocardial infarct. what is this caused by
angina from lack of CO2
heart tissue damage due to a lack of oxygen
hardening of the arteries
heart failure from high blood pressure
what is heart failure
a condition where the heart stops beating
a condition in which the heart cannot pump enough blood to meet the body's needs
a heart attack
a condition where the patient experiences chest pain
true or false. heart failure and congestive heart failure are the same
true
false
which is not a type of heart failure
right sided heart failure
left sided heart failure
congestive heart failure
myocardial heart failure
what are common signs and symptoms of heart failure
shortness of breath, dyspnea
fatigue
swelling
all of the above
true or false. a patient can have heart failure without being aware of it.
true
false
how many adults in the United States have been diagnosed with heart failure
1.3 million
2.4 million
6.5 million
9.6 million
Mr. Jones' electrical recording showed a heart rate of 120 beats per minute. This is called
encephalography
echocardiocardiography
electrocardiogram
electrolysis
Mr. Jones' eletrical recording showed a heart rate of 120 bpm. this is called
bradycardia
sinus arrhythmia
sinus rhythm
tachycardia
Mr. Jones had several strep infections as a child that was not treated. this caused what complication?
angina pectoria
congestive heart failure
heart block
rheumatic heart disease
lack of oxygen to the heart muscle can cause
angina pectoria
congestive heart failure
heart block
atherosclerosis
Mr. Jones came into the ER with c/o SOB and chest discomfort. an ECG revealed that his ventricles were not contracting effectively. His dx is
angina
heart block
heart failure
PVCs
The valve which prevents blood from flowing from the right ventricle into the right atria is the
aortic valve
bicuspid valve
pulmonary valve
tricuspid valve
The valve that prevents blood from flowing back into the right ventricle is the
aortic valve
bicuspid valve
pulmonary valve
tricuspid valve
Rheumatic fever can cause damage to which heart valve?
aortic valve
biscuspid valve
pulmonary valve
tricuspid valve
This triggers contraction in the atria
sa node
av node
qt node
av bundles
The place where the electrical current starts and which is considered the heart's pacemaker
sa node
right atrium
atrioventricular node
left ventricle
the definition of systole/diastole is
depolarization/repolarization
automaticity/relaxation
delays/contraction
plumbing/electricity
the medication that is used to slow and strengthen your heart is called:
nitroglycerin
norvasc
digitalis
anticoagulant
This medication vasodilates and decreases blood pressure to increase blood flow
lotensin
tenormin
lasix
nitroglycerin
a device used to measure the pressure against the arteries of the body
apparatus
gauge
sphygmomanometer
millimeter
If there is an occlusion in the left descending coronary artery, what's its nickname
wedding maker
widowmaker
headache
powerpoint
a group of disorders that causes a thickening and hardening of the arteries
atherosclerosis
arteriosclerosis
hypertension
stroke
what layer of the heart would be susceptible to infections caused by bacteria in the blood?
epicardium
myocardium
pericardium
endocardium
In the heart, the mixing of oxygen-poor and oxygen rich blood is prevented by the
mitral valve
tricuspid valve
septum
pericardium
The left side of the heart is responsible for pumping
oxygenated blood to the body
oxygenated blood to the lungs
deoxygenated blood to the body
deoxygenated blood to the lungs
