What is the typical range for normal adult blood pressure?

• A. 90/60 to 110/75
• B. 130/80 to 150/100
• C. 110/70 to 130/90
• D. 100/60 to 120/80

Answer: (C)

Blood pressure shows how forcefully the heart pushes blood through the arteries, so the normal range for adults is a band of values that indicate good perfusion without stressing the vessels too much. A commonly taught normal window is about 110 to 130 systolic and 70 to 90 diastolic. This span covers readings that most people fall into as healthy and not yet high enough to be labeled hypertension, while avoiding the lower end that could suggest hypotension. In practice, readings around this range reflect adequate cardiac output with reasonable vascular resistance, making it the best match for typical normal adult blood pressure.
