Cardiology Fisdap Exam for EMT/67 Questionsand Answers
A 44-year-old man reports dizziness and lightheadedness. His BP is 88/26
mm Hg, his heart rate is 190 beats per minute and weak. His skin is cool
clammy and pale. Which of the following would BEST explain why his BP is
low? - -Decreased ventricular filling time
-Switching compressors during two-rescuer CPR: - -should occur every two
minutes throughout the arrest
-Stable angina - -chest pain that occurs when a person is active or under
severe stress
-Unstable angina - -chest pain that occurs while a person is at rest and not
exerting himself
-What occurs during recoil of the chest in between compressions - -a
vacuum is created and blood returns to the heart
-A group of symptoms caused by myocardial ischemia; includes angina and
myocardial infarction - -acute coronary syndrome
-A heart attack; death of the heart muscle following obstruction of blood
flow to it; in this context the attack is "new" or "happening right now" - -
acute myocardial infarction (AMI)
-Transient (short-lived) chest discomfort caused by partial or temporary
blockage of blood flow to the heart muscle; also called angina - -angina
pectoris
-a weakness in the wall of the aorta that makes it susceptible to rupture - -
aortic aneurism
-the one way valve that lies between the left ventricle and the aorta keeps
blood from flowing back into the left ventricle after the left ventricle ejects its
blood into the aorta; one of the four heart valves - -aortic valve
-a tracing on an ECG that is the result of interference, such as patient
movement, rather than the heart's electrical activity - -artifact
-the complete absence of all heart electrical activity - -asystole
-the ability of cardiac muscle cells to contract without stimulation from the
nervous system - -automatically
, -when the heart fails to generate effective and detectable blood flow; pulses
are not palpable, even if muscular and electrical activity continues in the
heart - -cardiac arrest
-a disorder in which the heart loses part of its ability to effectively pump
blood, usually as a result of damage to the heart muscle and usually
resulting in a backup of fluid into the lungs - -congestive heart failure
-the blood vessels that carry blood and nutrients to the heart muscle - -
coronary arteries
-to shock the fibrillating (chaotically beating) heart with specialized electric
current in an attempt to restore a normal, rhythmic beat - -defibrillate
-swelling in the part of the body closest to the ground, caused by the
collection of fluid in the tissues; a possible sign of congestive heart failure - -
dependent edema
-Widening of a tubular structure such as a coronary artery. - -dilation
-a condition in which the inner layers of an artery, such as the aorta,
become seperatated, allowing blood (at high pressures) to flow between the
layers - -dissecting aneurysm
-An irregular or abnormal rhythm of the heart - -dysrhythmia
-an emergency situation created by excessively high blood pressure, which
can lead to serious complications such as a stroke or aneurysm - -
hypertensive emergency
-death of body tissues, usually caused by interruption of its blood supply - -
infarction
-the inside diameter of an artery or other hollow structure - -lumen
-the heart muscle - -myocardium
-a blockage, usually of a tubular structure such as a blood vessel - -
occlusion
-a blood clot that has formed within a blood vessel and is floating within the
bloodstream - -thromboembolism
-disorganized, ineffective quivering of the ventricles, resulting in no blood
flow and a state of cardiac arrest - -ventricular fibrillation
