The correct answer here would be arrived at by dividing the total oxygen consumption by the arteriovenous oxygen gradient, according to what I could find on the internet about this kind of calculation.

Now, I’m not an expert in nursing or in these measurements, so I cannot tell you which measurements are needed out of what is given. If I look at the previous answer, they got 6.25 L/min, or answer D, and they used all of the measurements given.

In light of this, I am almost positive that answer D is the correct answer, especially as I have not found a calculator that asks for these specific measurements when calculating the cardiac output of a patient with the provided numbers.
