EMT JBL exam 3 Questions With Accurate Answers.
Myocardium - accurate answers-heart muscle
stroke volume - accurate answers-the volume of blood pumped out by a
ventricle with each heartbeat
coronary arteries - accurate answers-supply oxygen-rich blood to the
myocardium
carotid arteries - accurate answers-supply head and brain with blood
capillaries - accurate answers-allow the exchange of nutrients and waste at
the cellular level
superior vena cava - accurate answers-receives blood from the head and arms
and chest and empties into the right atrium of the heart
inferior vena cava - accurate answers-A vein that is the largest vein in the
human body and returns blood to the right atrium of the heart from bodily
parts below the diaphragm.
red blood cells - accurate answers-carry oxygen
white blood cells - accurate answers-fight infection
platelets - accurate answers-clot blood
plasma - accurate answers-Liquid part of blood cells float in
systolic blood pressure - accurate answers-created during the contraction of
the left ventricle
diastolic blood pressure - accurate answers-when left ventricle is at rest
cardiac output - accurate answers-heart rate x stroke volume
Ischemia - accurate answers-decreased blood flow
, atherosclerosis - accurate answers-hardening of the arteries
acute coronary syndrome (ACS) - accurate answers-signs and symptoms
indicating an active process of atherosclerotic plaque buildup or formation of
a thrombus, or spasm within a coronary artery, causing a reduction or loss of
blood flow to myocardial tissue; includes unstable angina and other
pathological events leading to myocardial infarction (MI); early diagnosis and
rapid treatment are critical to avoid or minimize damage to heart muscle
angina pectoris - accurate answers-chest pain, which may radiate to the left
arm and jaw, that occurs when there is an insufficient supply of blood to the
heart muscle; short lived pain; is relieved with rest
unstable angina - accurate answers-chest pain at rest or chest pain of
increasing frequency
stable angina - accurate answers-relieved after rest or nitro
asystole - accurate answers-the absence of a heartbeat
cardiogenic shock - accurate answers-Shock caused by inadequate function of
the heart, or pump failure. signs: anxiety, "air hunger", high pulse rate,
decrease in body temp, possible low blood pressure. treatment: position
patient comfortably, admin o2, assist ventilations, presserve body heat,
transport
congestive heart failure (CHF) - accurate answers-the failure of the heart to
pump efficiently, leading to excessive blood or fluids in the lungs, the body, or
both; Signs: agitation, chest pain, disttended neck veins, difficulty breathing
when laying down, high blood pressure and tachycardia, skin pale cyanotic
sweaty, rales Icrackles)
hypertensive emergency - accurate answers-An emergency situation created
by excessively high blood pressure, which can lead to serious complications
such as stroke or aneurysm.
aortic aneurysm - accurate answers-A weakness in the wall of the aorta that
makes it susceptible to rupture.
