Stage I hypertension is defined by specific blood pressure readings that indicate a mild elevation that can be managed through lifestyle changes and possibly medication. According to the American College of Cardiology/American Heart Association (ACC/AHA) guidelines, Stage I hypertension is classified when blood pressure readings fall within the range of 130-139 mmHg systolic or 80-89 mmHg diastolic.

The correct definition of Stage I hypertension corresponds to the range of 130-139 systolic and 80-89 diastolic readings, which clearly delineates it as a significant yet early stage of hypertension that requires attention but is less severe than higher stages of hypertension.

The other options refer to either normal or elevated blood pressure categories or more severe stages of hypertension. For example, lower ranges indicate normal or elevated measurements, while higher ranges, such as 140-159/90-99 and 160-179/100-109, classify as Stage II hypertension, which suggests a more urgent need for medical intervention and management. Understanding these ranges is essential for correctly diagnosing and managing hypertension in clinical practice.
