Fifteen hours after admission, your client's CPK-MB level is markedly increased. Which interpretation of the findings by the nurse would be appropriate?
1. Cellular necrosis of myocardial tissue has occurred.
2. Lactic acid is present.
3. Thrombolytic therapy is indicated.
4. Cardiac function has returned to normal.
Cellular necrosis of myocardial tissue has occurred.
Rationale: CPK-MB is the intracellular enzyme that is released when cell damage and death occur. The ph is the indicator of lactic acid build-up. 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; CPK-MB becomes elevated when myocardial cell death has occurred.
