Question

A patient's vital signs are pulse 90, respirations 24, and BP 128/64 mm Hg, and cardiac output is 4.7 L/min. The patient's stroke volume is _____ mL. (Round to the nearest whole number.)

Answer 1

The patient's stroke volume is 52 mL.

Step-by-step explanation:

The patient's stroke volume can be calculated by dividing the cardiac output (CO) by the heart rate (HR). In this case, the patient's CO is 4.7 L/min and the HR is 90 bpm. Using the equation SV = CO/HR, we can find the stroke volume:

SV = 4.7 L/min / 90 bpm = 0.052 L/bpm = 52 mL/bpm

Rounding to the nearest whole number, the patient's stroke volume is 52 mL.
