A person has a stroke volume of 70 mL and a heart rate of 72 beats per minute. What is the cardiac output?
Correct answer D. 5.04 L/min
Explanation
Cardiac output = stroke volume × heart rate = 70 mL × 72 min⁻¹ = 5040 mL/min = 5.04 L/min. Adding the values or slipping a factor of 10 gives the distractors.
