What is the typical normal systolic blood pressure range for a healthy adult?

• A. 90 to 120 mmHg
• B. 100 to 140 mmHg
• C. 110 to 170 mmHg
• D. 95 to 135 mmHg

Answer: (B)

Systolic blood pressure is the pressure in the arteries during the heart’s contraction, and in a healthy adult at rest this value isn’t a single fixed number but falls within a broad, normal band. The best choice is the range that spans readings high enough to ensure adequate perfusion but not so high as to be considered elevated or hypertensive, recognizing that there is natural variability among individuals and measurement conditions. The other options tend to be either too restrictive or extend into values typically regarded as higher-than-normal, so they don’t capture the typical resting range as well.
