Answer to Question 1

3

Rationale 1:Diuretics increase urine flow and lower blood volume. They do not have inotropic effects on the heart.
Rationale 2: Cardiac glycosides have a positive inotropic effect.
Rationale 3: Beta-adrenergic blockers have a negative inotropic effect.
Rationale 4:Phosphodiesterase inhibitors have a positive inotropic effect.

Global Rationale: Beta-adrenergic blockers have a negative inotropic effect. Cardiac glycosides and phosphodiesterase inhibitors have a positive inotropic effect. Diuretics increase urine flow and lower blood volume.

Answer to Question 2

1

Rationale 1: The ability to increase the strength of contraction is called a positive inotropic effect.
Rationale 2: Negative chronotropiceffect would be a reduction of the rate or number of the contractions.
Rationale 3: Preload is the degree to which the heart fibers are stretched just prior to contraction.
Rationale 4: Afterload is the pressure in the aorta that must be overcome for blood to be ejected from the left side of the heart.

Global Rationale: The ability to increase the strength of contraction is called a positive inotropic effect. Negative chronotropiceffect would be a reduction of the rate or number of contractions. Preload is the degree to which the heart fibers are stretched just prior to contraction. Afterload is the pressure in the aorta that must be overcome for blood to be ejected from the left side of the heart.
