correct answers Fourth Left ICS, left sternal border
Which heart valves are open and which ones are closed during ventricular diastole? correct answers
Triscuspid and Mitral valves are open
Pulmonic and aortic valves are closed
Cardiac output is derived from ____ and ____? correct answers Stroke volume x HR
The brachiocephalic artery divides to form the right subclavian and the _______? correct answers Right
subclavian artery and right common carotid
What is Pulse Pressure? correct answers The difference between systolic and diastolic blood pressure
What is the Pulse Pressure (PP) of the following patient?
• Systolic: 150
• Diastolic: 75
• CVP: 10
• PAWP: 8
• Cardiac output: 5 correct answers 75
What is the Pulse Pressure (PP) of the following patient?
• Systolic: 140
• Diastolic: 80
• CVP: 10
• PAWP: 8

What is the Pulse Pressure (PP) of the following patient?
• Systolic: 130
• Diastolic: 70
• CVP: 10
• PAWP: 8
• Cardiac output: 5 correct answers 60
A 78 yr. old patient goes to his to cardiologist. Assessment shows a diastolic murmur prominent over the
left sternal border at the 2nd
intercostal space, a decrease in diastolic pressure, and an increase in pulse pressure. Which is happening
with this patient? correct answers Pulmonic regurgitation. Diasolic murmur indicates regurgitation back
through valve.
, What does the P wave on an EKG represent? correct answers left and right atrial depolarization and atrial
contraction
What does the P-R interval on an EKG represent? correct answers Time between onset of Atrial
depolarization and onset of ventricular depolarization
What does the Q wave on an EKG represent? correct answers Depolarization of the septum
What does the QRS complex on an EKG represent? correct answers Depolarization of the ventricles
What does the ST segment on an EKG represent? correct answers Represents the interval between
ventricular depolarization and repolarization
What does the T wave on an EKG represent? correct answers Repolarization of the ventricles
What conditions can cause the pulse pressure to increase? correct answers Valve regurgitation
Aortic stiffening
CAD or MI
Blood transported by the pulmonary veins returns to the _____? correct answers Left atrium
The valve located between the left ventricle and the blood vessel leaving the left ventricle is the _____?
correct answers Aortic valve
The valve located between the right atrium and the right ventricle is the ______? correct answers
tricuspid valve
A patient with a myocardial infarction suddenly develops a loud systolic murmur. What is this caused
from? correct answers Papillary Muscle Rupture
What measures left ventricular preload? correct answers PCWP or direct LAP
How can you treat a decreased PAWP? correct answers Fluid
Pulmonary vasodilators if Pulmonary hypertension
Valve replacement if stenotic or insufficient valves: pulmonic stenosis and insufficiency.
Treating right ventricular failure
Afterload is defined as ________? correct answers The pressure the heart must work against in order to
eject blood during systole
The bedside RN has obtained cardiac output, and reports to you that the cardiac output is 2 L/min.
Based upon this cardiac output, what
interventions should be completed? correct answers Find and treat the cause of low CO.
Positive inotropes to improve contractility
Increase preload if volume depleted
arterial vasodilators if high afterload is causing the problem
