Answer to Question 1

Air-filled areas have a percussion note of tympany. A resonant note can be elicited by percussing a patient with normal lungs. Flatness is heard over bone and dullness is heard over the organs.

Answer to Question 2

Medications such as beta-blockers and calcium channel blockers will reduce myocardial oxygen demand, decreasing cardiac contractility. Medications such as Primacor, Digoxin, and potassium chloride will increase cardiac contractility.
