Question

If the systolic pressure is 120 mm Hg and diastolic pressure is 80 mm Hg, the pulse pressure is

• A. $120\times 80=9600\text{mm Hg}$
• B. 120 + 80 = 200 mm Hg
• C. 120 - 80 = 40 mm Hg
• D. $\frac{120}{80}=1.5\text{mm Hg}$

Answer 1

The correct option is C 120 - 80 = 40 mm Hg

The pulse pressure can be defined as the difference between the diastolic and systolic pressure of an individual's heart. If the normal diastolic and systolic pressure of the adult human heart is 120 mm Hg and 80 mm Hg respectively, then the pulse pressure is 120 - 80 = 40 mm Hg.
