A nurse is evaluating the blood pressure (BP) results for multiple clients with cardiac problems on a telemetry unit. Which BP reading suggests to the nurse that the client’s mean arterial pressure (MAP) is abnormal and warrants notifying the physician?

ExplanationA MAP of less than 60 mm Hg indicates that there is inadequate per- fusion to organs. The mean arterial pressure is calculated by the sum of the SBP + 2DBP and then divided by 3 [MAP = (SBP + 2DBP)/3]. Thus the MAP of 98/36 mm Hg is (98 + 72)/3 = 170/3 = 56.7. The mean arterial pressure of 94/60 is 71.3. The mean arterial pressure of 110/50 is 70. The mean arterial pressure of 140/78 is 98.7.
