  2. extension of the MI
  3. renal failure
  4. liver failure

Answer to Question 1

Correct Answer: 1
The normal heart rate range is 60100 beats per minute. A heart rate greater than 100 beats per minute is called tachycardia. A heart rate less than 60 beats per minute is called bradycardia. A heart rate between 60 and 90 beats per minute would be considered within the normal range.

Answer to Question 2

Correct Answer: 1
A pathologic S3 (a third heart sound that immediately follows S2, called a ventricular gallop) results from myocardial failure and ventricular volume overload such as heart failure. Manifestations of MI extension include chest pain and a return of positive laboratory findings (CPK-MB and troponin). This heart sound is not associated with renal or liver failure.
