Final answer:
To calculate the cardiac output for the given patient with a heart rate of 80 bpm and a stroke volume of 70 mL/beat, you multiply the two values to get a cardiac output of 5600 mL/min, which corresponds to answer choice (e).
Step-by-step explanation:
If the heart rate for a patient is 80 bpm (beats per minute), and her stroke volume is 70 mL per beat, then her cardiac output can be calculated by multiplying heart rate by stroke volume.
Cardiac output = Heart rate × Stroke volume
Cardiac output = 80 bpm × 70 mL/beat
Cardiac output = 5600 mL/min or 5.6 L/min
Therefore, the correct answer to the question is:
e. 5600 mL/min
