Which blood pressure reading is considered to fall within the normal range?

1. 119/75

2. 135/90

3. 91/70

4. 140/80

The correct answer is: 119/75

A blood pressure reading of 119/75 is classified as normal based on established guidelines. Normal blood pressure is generally defined as being below 120 systolic and below 80 diastolic. In this case, both the systolic (119) and diastolic (75) values are well within those limits, indicating a healthy pressure level for the cardiovascular system. In contrast, a reading of 135/90 falls into the category of elevated or stage 1 hypertension, where the systolic value is over 130 and diastolic is over 80. The reading of 91/70 indicates lower-than-normal blood pressure, commonly referred to as hypotension, which may lead to dizziness or fainting. Lastly, 140/80, while it has a normal diastolic value, presents a raised systolic level that qualifies as stage 1 hypertension. Overall, the reading of 119/75 is the only option that aligns with the normal range for blood pressure.
