Final answer:
The mean arterial pressure can be calculated using the formula: MAP = diastolic pressure + 1/3 * pulse pressure. Given the blood pressure as 140/70 mm Hg, the pulse pressure is 70 mm Hg. Plugging in the values, the mean arterial pressure is approximately 93 mm Hg.
Step-by-step explanation:
The mean arterial pressure (MAP) can be calculated using the formula:
MAP = diastolic pressure + 1/3 * pulse pressure
Given that the patient's blood pressure is 140/70 mm Hg, we can calculate the pulse pressure as the difference between the systolic and diastolic pressures: 140 - 70 = 70 mm Hg. Plugging in these values, we get: MAP = 70 + 1/3 * 70 = 70 + 23.3 = 93.3 mm Hg.
Therefore, the mean arterial pressure is approximately 93 mm Hg.
