Question

patricia went to the doctor and her blood pressure was 130/90. what is patricias mean arteriole pressure?
○ 76.67 mmhg
○ 103.33 mmhg
○ 100 mmhg
○ 143.33 mmhg

Explanation:

Step1: Recall the formula for mean arterial pressure (MAP)

The formula for mean arterial pressure is \( MAP = \frac{2 \times \text{diastolic} + \text{systolic}}{3} \). Here, systolic pressure is 130 mmHg and diastolic pressure is 90 mmHg.

Step2: Substitute the values into the formula

Substitute systolic = 130 and diastolic = 90 into the formula: \( MAP=\frac{2\times90 + 130}{3}\)

Step3: Calculate the numerator

First, calculate \( 2\times90 = 180 \), then add 130: \( 180+130 = 310 \)

Step4: Divide by 3

Now, divide 310 by 3: \( \frac{310}{3}\approx103.33 \) mmHg

Answer:

103.33 mmHg (corresponding to the option "103.33 mmHg")
