The standard policy on the cardiac unit states, Notify the health care provider for mean arterial pressure (MAP) less than 70 mm Hg. The nurse will need to call the health care provider about the
 
  a. postoperative patient with a BP of 116/42.
  b. newly admitted patient with a BP of 150/87.
  c. patient with left ventricular failure who has a BP of 110/70.
  d. patient with a myocardial infarction who has a BP of 140/86.

Question 2

When the nurse is monitoring a patient who is undergoing exercise (stress) testing on a treadmill, which assessment finding requires the most rapid action by the nurse?
 
  a. Patient complaint of feeling tired
  b. Pulse change from 87 to 101 beats/minute
  c. Blood pressure (BP) increase from 134/68 to 150/80 mm Hg
  d. Newly inverted T waves on the electro-cardiogram

Answer to Question 1

ANS: A
The mean arterial pressure (MAP) is calculated using the formula MAP = (systolic BP + 2 dias-tolic BP)/3. The MAP for the postoperative patient in answer 3 is 67. The MAP in the other three patients is higher than 70 mm Hg.

Answer to Question 2

ANS: D
ECG changes associated with coronary ischemia (such as T-wave inversions and ST segment de-pression) indicate that the myocardium is not getting adequate oxygen delivery and that the ex-ercise test should be terminated immediately. Increases in BP and heart rate (HR) are normal re-sponses to aerobic exercise. Feeling tired is also normal as the intensity of exercise increases dur-ing the stress testing.
