A nurse is teaching the partner of a client who had an acute myocardial infarction (MI) about the reason blood was drawn from the client. Which of the following statements should the nurse make regarding cardiac enzymes studies?

"These tests help determine the degree of damage to the heart tissues." Answer Rationale: Cardiac enzyme studies are obtained because the degree of enzyme elevation reflects the degree of damage to the myocardium. The enzymes most commonly measured are CPK and troponin. These enzymes have a characteristic rise and fall pattern after an MI.
