Yasmine is a 38-year old woman who is trying to get into working out. Her resting HR is currently 68bpm. Assuming a max HR of 220- age, what percentage of HRmax would the above heart rate zones from question 1 (intensities found for HRR) be for Yasmine?
Blood pressure is usually given as the ratio of the maximum pressure (systolic pressure) to the minimum pressure (diastolic pressure). For example a typical value for this ratio for a human would be 120/70, where the pressures are in mm Hg (millimeters of mercury, SG = 13.6). What would these pressures be in kPa (kilo Pascals)?: (a) systolic pressure (kPa), (b) diastolic pressure (kPa).
5 29.At maximal exercise, a recreationally active individual has an a-vO2 difference of 0.16 mL O2/mL of blood, a stroke volume of 122 mL, and a heart rate of 191 bpm. What is their V̇O2max? A. 3960 mL/min B. 4150 mL/min C. 3620 mL/min D. 3730 mL/min
In the same BP measurement= 120/80, what is the arterial pressure when the left ventricle is at the peak of its contraction? Choices: 120804093
Sue goes to the gym and after an initial warm-up, she increases her exercise level pushing herself to maximum. At this point her heart rate is 175 beats/min and her stroke volume is 135 ml/beat. What is her cardiac output now? At this point, by how many ml/min has her CO increased over her resting CO? What % increase over resting is this? (Use the following equation). amount of increase in CO in ml/min % increase = _____________ X 100% original CO (resting) ml/min What term is used to describe this increase in CO?
You measure a patients blood pressure at 130/85. Calculate the patients pulse pressure and mean arterial pressure. Determine whether each pressure is low, normal, or high.

If cardiac output is 16L/min during jogging, and 25% of total blood flow is being diverted to skeletal muscle, how much blood is being delivered to skeletal muscle in L/min? a. 2 b. 5 c. 6 d. 1 e. 4 f. 3
Order states: dopamine 400mg in 250ml D5W, administer 5 mcg/kg/min IV. The patient weighs 192 lbs. how many ml/hr will you administer?
Systemic blood pressure is defined as the ratio of two pressures—systolic and diastolic—both expressed in millimeters of mercury. Normal blood pressure is about 120mm/80mm which is usually just stated as 120/80. What would normal systemic blood pressure be if, instead of millimeters of mercury, we expressed pressure in each of the following units, but continued to use the same ratio format? Part A) atmosheres = a)120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4 Part B) torr = a) 120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4 Part C) Pa = a)120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4 Part D) N/ m^2 = a)120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4 Part E) psi = a)120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4
