What blood pressure range is considered normal for a healthy adult?

• A. <120/80 mmHg
• B. <140/90 mmHg
• C. <100/60 mmHg
• D. <130/85 mmHg

Answer: (A)

Normal blood pressure for a healthy adult is defined as systolic under 120 mmHg and diastolic under 80 mmHg. That means readings below 120/80 mmHg are considered normal, because both the upper (systolic) and lower (diastolic) numbers stay in that safe range. The other options push one or both numbers into higher categories: 140/90 mmHg indicates hypertension; 100/60 mmHg is a low reading (which can be normal for some people but is not the standard normal benchmark); 130/85 mmHg is higher than normal and may be labeled as elevated or stage 1 depending on guidelines. So the most accurate choice for normal is the measurement below 120/80 mmHg.
