Question

If Mary has a heart rate of 65 bpm, a cardiac output of 3,250 ml/min, a systolic blood pressure of 150 mm Hg and a diastolic BP of 90 mm Hg, what is her mean arterial pressure?
O 90
O 120
О 130
O 110
О 60

Bot · Answer

The formula for mean arterial pressure (MAP) is MAP = diastolic pressure + 1/3(systolic pressure - diastolic pressure).

Plugging in the given values, we get:

MAP = 90 + 1/3(150-90)
MAP = 90 + 20
MAP = 110

Therefore, Mary's mean arterial pressure is 110 mm Hg.

The correct answer is: O 110.
