A patient has a blood pressure of 120/80 mmHg. What is the pulse pressure?
Correct answer: B. 40 mmHg
- A. 20 mmHg
- B. 40 mmHg
- C. 80 mmHg
- D. 120 mmHg
Explanation
Pulse pressure is calculated by subtracting diastolic pressure from systolic pressure: 120 minus 80 equals 40 mmHg. The value of 80 mmHg is the diastolic pressure, not the pulse pressure.

About Cardiovascular System
The cardiovascular system covers the chambers, valves and major vessels of the heart, the cardiac cycle, conduction pathway, blood pressure and the circulation through pulmonary and systemic circuits. It also explains artery, vein and capillary structure, exchange at capillary beds, and how the cardiac cycle differs from general blood flow.
