NSC 114 Circulation Exam Questions
and Answers All Correct
What would most likely be included in the evaluation of the client foal of "Demonstrate
adequate tissue perfusion?"
A. Symmetrical chest expansion
B. Uses pursed-lip breathing
C. Brisk capillary refill
D. Activity intolerance - Answer-C. Brisk capillary refill
Which client is most likely to experience poor cardiac output?
A. A client who has recently completed exercising and is talking easily with an exercise
partner
B. A client who has a stroke volume of 70 mL per beat and a heart rate of 70
beats/minute
C. A client with a sustained heart rate of 150 beats/minutes
D. A client who receives a positive inotrophic medication - Answer-C. A client with a
sustained heart rate of 150 beats/minutes
When would an increase in preload have a negative effect/outcome for the client? -
Answer-It increases the contractility or stretch but only to s certain point (frank-starling
law). Once it reaches that point, contractility and cardiac output decrease.
What medication classification decreases preload? - Answer-diuretics
which side of the heart is primarily affected by afterload? - Answer-Left ventricle
What can cause an increase in afterload (what can cause the left side of the heart to
work harder)? - Answer-High blood pressure (hypertension)-the left ventricle has to
create a pressure above the client's diastolic pressure to pump blood into the
circulation. Arterial vasoconstriction: the left ventricle works harder.
Blood altercations for anemia: - Answer-- chronic fatigue
- pallor
- shortness of breath
- hypotension
Assessing - Answer-- comprehensive history
- physical examination
- review relevant data
, What should you assess for a patient with suspected cardiovascular problems - Answer-

What are the layers of the heart? - Answer-epicardium, myocardium, endocardium
What are the chambers of the heart? - Answer-right atrium, right ventricle, left atrium,
left ventricle
What does the atrioventricular valve separate? - Answer-atria and ventricles (tricuspid -
right, bicuspid or mitral - left)
What does the semi lunar (half moon) valve separate? - Answer-ventricles from great
vessels
How does deoxygenated blood move through the cardiovascular system? - Answer-it
enters in the right side of the heart, exits to lungs
How does oxygenated blood move through the cardiovascular system? - Answer-
returns via left side of the heart, exits to the body
Whats the cardiac cycle? - Answer-one complete heartbeat; systole, diastole
What is apart of the cardiac conduction system? - Answer-automaticity, sinoatrial (SA or
sinus) node, atrioventricular (AV) node, bundle of his, purkinje fibers
What is cardiac output (CO)? - Answer-The amount of blood ejected from the heart
each minute
What is stroke volume (SV)? - Answer-amount of blood ejected from the heart per beat
stroke volume x heart rate = - Answer-cardiac output (CO)
Whats a normal cardiac output (CO)= - Answer-4 to 8 L/min
