Answer to Question 1

Correct Answer: 1
Rationale: Cardiac glycosides increase cardiac output by increasing the force of contraction. Diuretics lower blood volume, beta blockers lower heart rate, and ACE inhibitors lower peripheral vascular resistance and blood volume.

Answer to Question 2

Correct Answer: 4
Rationale: Increased preload results in a more forceful contraction, and increases cardiac output. Hypovolemia is a lower blood volume, and will result in lower cardiac output. Peripheral vascular resistance increases afterload and increases the workload on the heart. A reduction in cardiac contractility results in lower preload and subsequent cardiac output.
