How do you determine a patient’s cardiac output?
  1. Multiply stroke volume by patient’s systolic blood pressure
  2. Multiply stroke volume by patient’s diastolic blood pressure
  3. Multiply stroke volume by patient’s age
  4. Multiply stroke volume by patient’s heart rate
Explanation
Answer - D - Cardiac output is the amount of blood that is pumped out of a person’s heart in one minute. To come up with the correct number, you have to multiply the patient’s stroke volume by their heart rate. For example, if a patient’s stroke volume is 80ml’s and their heart rate is 65 beats per minute, their cardiac output is 5200 ml.
