answer this question
BLOOD AND FLUID QUESTION 1 (0A patient's blood pressure taken at the arm is 120 mmHg systolic and 70 mmHg diastolic. What would you expect the blood pressure (systolic and diastolic pressures) to be at the top of the head given that this point is 40 cm above the measurement point? Remember blood pressure is a gauge pressure and that 1 kPa = 7.5 mmHg. (The density of blood is about 1060 kg/m.) Choose one: a. 89...
