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.
