Q: Which of the following equations correctly calculates mean arterial pressure (MAP)?

$$\text{MAP} = \text{Diastolic Pressure} + \frac{1}{3}(\text{Systolic Pressure} - \text{Diastolic Pressure})$$

Q: A patient has a blood pressure of 120/80 mmHg. What is their pulse pressure?

$$\text{Pulse Pressure} = 120 - 80 = 40\ \text{mmHg}$$
