The nurse is planning to calculate a patient's coronary perfusion pressure. Which values are needed to do this calculation?

1. heart rate and diastolic blood pressure
2. systolic blood pressure and pulmonary artery wedge pressure
3. pulmonary artery wedge pressure and diastolic blood pressure
4. respiratory rate and diastolic blood pressure


3

Rationale: One way to evaluate the effectiveness of coronary perfusion is to calculate the coronary perfusion pressure. The coronary perfusion pressure is derived by subtracting the pulmonary artery wedge pressure from the diastolic blood pressure. Heart rate, systolic blood pressure, and respiratory rate are not used to calculate the coronary perfusion pressure.
