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
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.
To calculate the mean arterial pressure (MAP), you can use the following formula:
MAP = DBP + [(SBP - DBP)/3]
Given that Mary has a systolic blood pressure (SBP) of 150 mm Hg and a diastolic blood pressure (DBP) of 90 mm Hg, we can substitute these values into the formula:
MAP = 90 + [(150 - 90)/3]
Calculating the numerator first:
150 - 90 = 60
Dividing the numerator by 3:
60 / 3 = 20
Now, substituting the numerator in the formula:
MAP = 90 + 20
Calculating the sum:
90 + 20 = 110
Therefore, Mary's mean arterial pressure is 110 mm Hg. So, the correct answer is:
O 110
