Question 1

If there is more of a difference in the temperature of a thermal dilution test, what is happening?

Answer 1

Slower flow (lower CO)

Question 2

Answer 2

Snapping of the chordae tendineae in the ventricles (enlargement of ventricle)

Question 3

What is S4 caused by?

Answer 3

Overstretching of the ventricles

Question 4

What is the MOA of digoxin?

Answer 4

Increases Ca permeability, causing a longer contraction of the ventricular muscle, lowering end systolic volume (thereby increasing SV), and increasing CO

Question 5

Answer 5

Diastole
