What is the normal range for blood pressure?

• A. less than 120/80 mmHg
• B. 120-140/80-90 mmHg
• C. 140/90 mmHg or higher
• D. 110/70 mmHg

Answer: (A)

Normal blood pressure means the pressure in the arteries when the heart beats and at rest is in a healthy range. A commonly used standard defines normal as less than 120 systolic and less than 80 diastolic, i.e., under 120/80 mmHg. This threshold helps distinguish readings that are considered healthy from those that begin to carry higher cardiovascular risk. Readings in the 120–140 systolic or 80–90 diastolic range are higher than normal and may be labeled elevated or borderline high, while 140/90 mmHg or higher is categorized as hypertension. A value like 110/70 is within normal limits, but the typical definition of normal used in many contexts is below 120/80.
