Compression/ Ventilation ratio for one rescuer? Two? correct answers 1 rescuer = 30:2
2 rescuers = 30:2
Pediatric 2 rescuer is 15:2 but otherwise stays the same
What is the proper compression rate in CPR? correct answers 100-120 per minute
Compression rate for: Adults
Children?
Infants: correct answers Adults: 2 inches
Children: 1/3 depth of chest or 2 in
Infants: 1.5 inches
What are 2 rhythms are considered "shockable" rhythms? correct answers Ventricular Fibrilation
Pulseless Ventricular Tachycardia
Use the following terms to describe the flow of blood throughout the body:
Atrium, Ventricle, arteries, veins, aorta, pulmonary artery, pulmonary vein, capillaries, vena
cava, arterioles. correct answers 1. Deoxygenated blood travels through the superior and inferior
vena cava to the right atrium
2. The blood is pumped by the right ventricle to the pulmonary artery to the lungs. This is where
the blood is oxygenated before being sent back through pulmonary veins to the left atrium.
3. Blood flows into the left ventricle, which is responsible for pumping blood into the aorta and
out through arteries to the body.
4. Arteries branch off into arterioles, then to capillaries, which is where nutrient exchange occurs
with cells.
5. Last, blood flows back into the veins, into the superior and inferior vena cava before returning
to the heart.
What are two important roles of red blood cells? correct answers Transport oxygen to the cells
Transport carbon dioxide to the lungs
7 signs of cardiac comporomise correct answers 1. abnormal blood pressure
2. pain, pressure, or discomfort in the chest or abdomen
3. shortness of breath
4. palpitations
5. anxiety or irritability
6. abnormal pulse
7. Sudden onset of nausea or vomiting
You auscultate your patient's lungs and find crackles with difficulty breathing. Which side of the
heart is affected and why? correct answers Shortness of breath with crackles in the lungs is
, indicative of left-sided heart failure. Failure of the left ventricle to pump blood effectively causes
blood to be backed up to into the lungs (congested)
Right-sided heart failure causes blood to backup into body, causing pitting edema throughout the
body. What's the cause and name of this condition? correct answers Cor Pulmonale. The usual
cause is pulmonary disease, such as pulmonary hypertension or pulmonary stenosis (obstruction
in the P.A)
Preload correct answers Preload, also known as the left ventricular end-diastolic pressure
(LVEDP), is the amount of ventricular stretch at the end of diastole. Think of it as the heart
loading up for the next big squeeze of the ventricles during systole. Some people remember this
by using an analogy of a balloon - blow air into the balloon and it stretches; the more air you
blow in, the greater the stretch
Afterload correct answers Afterload, also known as the systemic vascular resistance (SVR), is
the amount of resistance the heart must overcome to open the aortic valve and push the blood
volume out into the systemic circulation. If you think about the balloon analogy, afterload is
represented by the knot at the end of the balloon. To get the air out, the balloon must work
against that knot.
List two organs in the right upper quadrant correct answers
List two organs in the right lower quadrant correct answers
List two organs in the left upper quadrant correct answers
List two organs in the left lower quadrant correct answers
On a normal EKG strip, what does the QRS complex represent and what is it's normal duration?
correct answers Ventricular depolarization; less than .12 seconds
QRS complex is a narrow complex usually less than or equal to 3 small boxes in length, or .12
seconds. It indicates ventricular depolarization. Conduction starts at the AV junction, through to
bundle of His, left and right bundles, and the purkinje system.
Rate for an Accelerated Junctional Rhythm is how many bpm? correct answers 60-100bpm.
inherent rates for junctional rhythm is 40-60, accelerated junctional is typically faster and is
identified by wave form
What occurs in a third degree heart block? correct answers a.k.a complete heart block
The atria and ventricles are completely dissociated.
