Answer to Question 1

F
Depolarization is not the same as contraction. Depolarization (an electrical event) is expected to result in contraction (a mechanical event). It is possible to see organized electrical activity on the cardiac monitor, yet evaluation of the patient reveals no palpable pulse. This clinical situation is called pulseless electrical activity (PEA).

Answer to Question 2

B
When the left ventricle contracts, freshly oxygenated blood flows through the aortic valve into the aorta and out to the body.
