A nurse is reviewing the laboratory findings of a client who experienced an acute myocardial infarction 6 days ago. Which of the following laboratory values should the nurse expect to remain elevated at this time?
Correct Answer: D

Correct Answer: 7.5
Rationale:
To calculate: (20 mEq / 40 mEq) × 15 mL = 7.5 mL, which is the correct dose to administer.
