  1. Oxygenated blood to the body
  2. Deoxygenated blood to the lung
  3. Oxygenated blood to the right atrium

Answer to Question 1

Correct Answer: 1
Rationale 1: The mitral valve separates the left ventricle from the left atrium. Problems with this valve will impede flow of oxygenated blood from the left atrium into the left ventricle for delivery to the body.
Rationale 2: The pulmonic valve separates the right ventricle from the pulmonary artery. Problems with this valve would impede delivery of deoxygenated blood back to the lung.
Rationale 3: The blood that returns to the right atrium is deoxygenated.
Rationale 4: The blood delivered to the left ventricle is oxygenated.

Answer to Question 2

Correct Answer: 3
Rationale: The period of the cardiac cycle between S1 and S2 is ventricular systole. Any extra heart sounds heard during this period of time would be documented as systolic. The period of time between S2 and the next S1 is diastole.
