Which statement about stage hypertension categories is true?

• A. Stage 1 corresponds to Systolic 120-129 and Diastolic <80
• B. Stage 1 corresponds to Systolic 130-139 and Diastolic 80-89
• C. Stage 1 corresponds to Systolic >140; Diastolic >90
• D. Stage 1 has no defined blood pressure values

Answer: (B)

Stage 1 hypertension is defined by systolic values in the 130–139 range or diastolic values in the 80–89 range. So a statement that links Stage 1 to those exact ranges correctly reflects how the categories are used to classify blood pressure. The other described ranges correspond to different categories: 120–129 systolic with diastolic under 80 is the elevated category, not Stage 1; systolic above 140 or diastolic above 90 indicates Stage 2; and there are defined values for these categories, so saying there are none is incorrect.
