Question 1

What is the correct progression of the cardiac impulse?

Accepted Answer

The correct progression of the cardiac impulse is from the sinoatrial (SA) node, which acts as the natural pacemaker of the heart, to the atrioventricular (AV) node, which delays the impulse to allow for complete atrial contraction before passing it to the bundle of His, which splits into the right and left bundle branches and then passes the impulse to the Purkinje fibers, which distribute it throughout the ventricles for effective contraction. Therefore, option C is the correct progression.

Question 5

What is the correct progression of blood through the heart and lungs?

Accepted Answer

The correct progression of blood flow through the heart and lungs is from the right atrium to the right ventricle, then to the lungs for oxygenation, then from the lungs back to the left atrium, and finally to the left ventricle, which pumps oxygenated blood out to the rest of the body.

Question 11

What term refers to the heart's ability to initiate its own electrical impulse?

Accepted Answer

Automaticity refers to the heart's ability to generate its own electrical impulses, which determines its rhythmicity. Arrhythmia refers to an abnormal heart rhythm, while ectopy refers to an electrical impulse that originates outside of the normal location in the heart.

Match each heart structure to its function or characteristic.
a.base
e.right atrium
b.aorta
f.left atrium
c.apex
g.right ventricle

Accepted Answer

The right atrium is the chamber of the heart that receives deoxygenated blood from the body through the superior and inferior vena cavae.

a.aortic valve
d.tricuspid valve
b.semilunar valve
e.mitral valve
c.pulmonary valve
-Located between the right ventricle and the pulmonary artery

Accepted Answer

The answer of Match each heart valve with its location.
a.aortic...

Question 15

Based on your memory of the heart's electrical system, what will happen if a patient's primary pacemaker fails?

Accepted Answer

If the patient's primary pacemaker fails, another area of the electrical system (such as the AV node or Purkinje fibers) will take over as the secondary pacemaker and initiate a heartbeat. While this may result in a slower heart rate or a less efficient contraction pattern, it will not necessarily cause cardiac arrest or ventricular fibrillation.

Question 16

Match each heart valve with its location.
a.aortic valve
d.tricuspid valve
b.semilunar valve
e.mitral valve
