  1. Heart rate (beats/min) / stroke volume (mL/beat).
  2. Systolic blood pressure  heart rate (beats/min).
  3. Systolic blood pressure  diastolic blood pressure.

Correct Answer: 4
Rationale 1: This is not the correct method of calculating cardiac output.
Rationale 2: This is not the correct method of calculating cardiac output.
Rationale 3: This is the correct method for determining pulse pressure, not cardiac output.
Rationale 4: CO = stroke volume (mL/beat)  heart rate (beats/min).
Global Rationale: CO = stroke volume (mL/beat)  heart rate (beats/min). The other equations are not appropriate for calculating cardiac output.
