Question 1 of 5
When considering the concepts related to blood pressure, which statement best describes the concept of mean arterial pressure (MAP)?
Correct Answer: C
Rationale: Mean Arterial Pressure (MAP) is the pressure that forces blood into the tissues, averaged over the cardiac cycle. It is not the pressure of the arterial pulse (
Choice
A), nor does it directly reflect the stroke volume of the heart (
Choice
B). While MAP involves systolic and diastolic pressures, it is not simply an average of these two values as diastole lasts longer. Instead, MAP is closer to diastolic pressure plus one third of the pulse pressure. The best description of MAP is that it represents the pressure forcing blood into the tissues, averaged over the cardiac cycle.
