Which reading represents a normal blood pressure?

• A. 110/70
• B. 120/80
• C. 140/90
• D. 90/60

Answer: (B)

Blood pressure has two numbers: the pressure during a heartbeat (systolic) and the pressure between beats (diastolic). A normal reading means both numbers fall within the healthy range, not too high and not unusually low. Among common example values, the reading that sits inside the typical healthy band for both numbers is considered normal. The other readings show either elevated pressure (one or both numbers too high) or lower-than-normal pressure. So the reading that stays within those normal limits for both numbers is the normal one.
