Blood pressure numbers of less than __ mm Hg are considered within the normal range.

🧠 Explanation:

Normal blood pressure is defined as a reading below 120/80 mm Hg, where 120 represents systolic pressure (pressure when the heart beats) and 80 represents diastolic pressure (pressure when the heart rests). “Considered” is a past participle used here to indicate evaluation or classification. Readings higher than this range may indicate prehypertension or hypertension, which can increase risks of heart disease and stroke. Alternatives like “regarded” or “deemed” could replace “considered” without changing meaning. Maintaining blood pressure within this range is crucial for cardiovascular health, and regular monitoring helps detect any early signs of abnormalities.
