Which blood pressure reading classifies an individual as having stage 1 hypertension?

• A. 120/80 mm Hg
• B. 130/85 mm Hg
• C. 135/80 mm Hg
• D. 140/90 mm Hg

Answer: (C)

Stage 1 hypertension is defined by blood pressure readings that fall within the range of 130-139 mm Hg for systolic pressure or 80-89 mm Hg for diastolic pressure. The reading of 135/80 mm Hg fits this classification, as the systolic value of 135 mm Hg is within the specified range for stage 1 hypertension. In contrast, values such as 120/80 mm Hg are considered normal, while 130/85 mm Hg is at the very lowest threshold of stage 1 but does not meet the systolic threshold consistently across the classification guidelines. The reading of 140/90 mm Hg meets the criteria for stage 2 hypertension, which is characterized by higher blood pressure values. Thus, the reading of 135/80 mm Hg is the one that aligns accurately with the defined parameters for stage 1 hypertension.
