What is the normal range for adult resting blood pressure?

• A. Approximately 130/85 to 150/95
• B. Approximately 70/40 to 90/60
• C. Approximately 90/60 to 120/80
• D. Approximately 100/70 to 130/85

Answer: (C)

The main idea here is identifying what normal resting blood pressure looks like in adults. Resting blood pressure is read as systolic over diastolic, reflecting pressure when the heart beats and when it rests between beats. A typical normal range is about 90/60 to 120/80. Values much lower than 90/60 can indicate hypotension, while values at or above 130/85 begin to fall into elevated or hypertensive categories, depending on the guideline. Among the options, 90/60 to 120/80 stays within what most standards consider normal for adults, making it the best match. The other ranges either dip into lower-than-normal pressures or extend into elevated/hypertensive ranges.
