Answer to Question 1

Saved me massive time.

Answer to Question 2

Correct Answer: 1

: CK-MB is the intracellular enzyme that is released when cell damage and death occur. CK-MB becomes elevated when myocardial cell death has occurred. The pH is the indicator of lactic acid buildup. Thrombolytic therapy is indicated within the first 12 hours after symptoms develop, thus, it is too late for this intervention. Cardiac function has not returned to normal.
