Question

If the heart rate for a patient is 80bpm, and her stroke volume is 70 mL/beat, then her cardiac output is Answers:

a. 0.87 mL/min
b. 1.1mL/min. c. 10mL/min.
d. 56 mL/min.
e. 5600 mL/min

Answer 1

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

Answer 2

The cardiac output for a patient with a heart rate of 80 bpm and a stroke volume of 70 mL/beat is calculated as 80 bpm multiplied by 70 mL/beat, resulting in a cardiac output of 5600 mL/min.

Step-by-step explanation:

If the heart rate for a patient is 80 beats per minute (bpm), and her stroke volume is 70 mL/beat, then her cardiac output can be calculated using the formula CO = HR × SV, where CO is cardiac output, HR is heart rate, and SV is stroke volume. Therefore, the cardiac output for this patient would be 80 bpm × 70 mL/beat = 5600 mL/min or 5.6 L/min. So the correct answer is e. 5600 mL/min.
