Which blood pressure measurement falls within the normal range?

• A. 112/68
• B. 140/90
• C. 90/60
• D. 130/70

Answer: (A)

Normal blood pressure in adults is typically defined as a systolic number under 120 mmHg and a diastolic number under 80 mmHg. The reading 112/68 fits neatly into that range, with both numbers well below those thresholds. The other options show pressures that exceed normal: 140/90 indicates high blood pressure, and 130/70 has a systolic value of 130, which is above the normal cutoff; while 90/60 is lower end of the spectrum and, though sometimes acceptable, is not as clearly within the standard normal range as 112/68.
