Answer to Question 1

B
The P wave is a positive wave representing atrial depolarization, the PR segment represents the electrical impulse as it moves through the AV node, the T wave represents ventricular repolarization, and the QRS complex represents the electrical impulse as it travels through the AV node.

Answer to Question 2

D
Moist heat is used to promote vasodilation, increase capillary permeability, decrease blood viscosity and reduce muscle tension. It is effective only when adequate vasculature is present.

Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
