Mediastinum
The inferior surface of the heart is formed by the - ANSWER Right and left ventricles
A branch of the right coronary artery supplies - ANSWER The right atrium and right
ventricle
The right atrium - ANSWER Receives blood from the superior and inferior vena
cavae and the coronary sinus
Although about 70% of ventricular filling occurs passively, ______ _______
contributes an additional 10% to 30% of blood flow to ventricular filling - ANSWER
Atrial kick
This layer of the heart is the innermost layer that lines its inner chambers, valves,
and is continuous with the innermost layer of the arteries, veins, and capillaries of
the body - ANSWER The endocardium
When a ventricle relaxes in the normal heart, blood is prevented from flowing back
into it by: - ANSWER The semilunar valve
The right ventricle - ANSWER Pumps unoxygenated blood into the pulmonary
circulation
The _______ pericardium is the inner layer of the pericardium, which is also the
outer layer of the heart wall called the ________ - ANSWER visceral, epicardium
What conditions are potentially reversible? - ANSWER Myocardial ischemia and
myocardial injury
What is true regarding cardiac output? - ANSWER Within limits, the more blood that
is returned to the heart, the greater the volume of blood that will be pumped during
the next contraction
A 65-year-old man presents with a sudden onset of substernal chest pain that
radiates to his left arm and jaw, and nausea. He states that his symptoms began
while at rest. The patient has a history of coronary artery disease and had a three-
vessel coronary artery bypass graft last year. His medications include diltiazem
(Cardizem) and nitroglycerin. He has no known allergies. On the basis of this
information presented, this patient is most likely experiencing a - ANSWER Acute
Coronary Syndrome
Your assessment reveals that the patient is anxious, his skin is pale and sweaty, and
