Cardiac

Question 1

Pulmonary artery carries what blood?

Answer 1

Deoxygenated blood to the lungs where it becomes oxygenated

Question 2

The pulmonary veins carry what blood?

Answer 2

Oxygenated blood that goes to L. Atrium

Question 3

What is preload?

Answer 3

The amount of blood returning to the R. side of the heart and the muscle stretch that the volume causes

Question 4

What happens when we have the stretch with preload?

Answer 4

ANP is released (excrete Na and H20)

Question 5

What is after load?

Answer 5

The pressure in the aorta and peripheral arteries that the L. ventricle pumps against to get blood out

Question 6

What is the pressure from after load referred to as?

Answer 6

Resistance

Question 7

Afterload

With HTN there is more or less resistance?

Answer 7

More!

Thats why HTN can lead to HF and pulmonary edema, bc high after load decreases CO and forward flow, as well as wears your heart out

Question 8

What is stroke volume?

Answer 8

The amount of blood pumped out of the ventricles with each beat

Question 9

CO = ___ X ____

Answer 9

HR x SV

Question 10

Cardiac output

What is dependent on an adequate CO?

Answer 10

Tissue perfusion

Question 11

Cardiac output

CO chances according to the ___

Answer 11

Body needs

Question 12

Factors that affect CO (3)?

Answer 12

HR and certain arrhythmias
BV
Decrease in contractility

Question 13

Factors that affect CO

What about BV?

Answer 13

Less volume = less CO

More volume = more CO

Question 14

Factors that affect CO

What about decrease in contractility?

Answer 14

MI, meds, cardiac muscle disease can cause

Question 24

Preload, after load, contractility, rate, rhythm

Hydralazine

Answer 24

Afterload

Question 25

Preload, after load, contractility, rate, rhythm Dopamine

Answer 25

this is an inotrope --improve contractility

Question 26

Preload, after load, contractility, rate, rhythm Diuretics

Answer 26

Answer 29

Afterload

Question 30

Preload, after load, contractility, rate, rhythm Verapamil

Answer 30

Rate control *this is CCB

Question 31

Preload, after load, contractility, rate, rhythm Antiarrhythmics (amiodarone)

Answer 31

Rhythm control
