A nurse is reading a client's medical record and notes that the client's cardiac output (CO) is listed as 5 L/min. Which calculation was used to determine the CO?
1. Heart rate (beats/min) / stroke volume (mL/beat).
2. Systolic blood pressure × heart rate (beats/min).
3. Systolic blood pressure – diastolic blood pressure.
4. Stroke volume (mL/beat) × heart rate (beats/min).
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.
