What is the MAP of 90/40?

The correct answer is 57 mmHg. To calculate MAP, I used the equation of DBP+((1/3*(DBP-SBP)). Mean arterial pressure is calculated to determine the average pressure in arterioles as an additional measurement to blood pressure (arterial and noninvasive). In an ICU setting, the goal MAP is commonly set as 60-65 mmHg.

What effect does norepinephrine have?

Norepinephrine increases systemic vascular resistance (SVR), thereby increasing afterload. It does not, however, increase PAWP, which is a measure of preload.

Why does the body adapt to specific changes in our body systems and environment? What is the core reason of adaptation?

The body is constantly trying to maintain homeostasis. All compensatory mechanisms that we see are a result of our bodies trying to stay in a specific range where we can best function.
