Final answer:
The mean arterial pressure (MAP) for a patient with a blood pressure of 110/80 mm Hg is 90 mmHg, calculated by the formula MAP = Diastolic pressure + 1/3(Systolic pressure - Diastolic pressure).
Step-by-step explanation:
The mean arterial pressure (MAP) of a patient with a blood pressure of 110/80 mm Hg can be calculated using the formula: MAP = Diastolic pressure + 1/3(Systolic pressure − Diastolic pressure). So, the MAP is 80 + 1/3(110 − 80) = 80 + 1/3(30) = 80 + 10 = 90 mm Hg. Therefore, the correct answer is C. 90 mmHg.
