Final answer:
Hypertension is defined as chronically elevated blood pressure, and is clinically diagnosed when blood pressure measurements are consistently at or above 140/90 mm Hg. Prehypertension is a blood pressure range between 120/80 and 140/90 mm Hg. Stage one hypertension refers to blood pressure readings between 130/80 and 139/89 mm Hg, while stage two hypertension refers to readings of 140/90 mm Hg or higher.
Step-by-step explanation:
Hypertension is defined as chronically elevated blood pressure, and is clinically diagnosed when blood pressure measurements are consistently at or above 140/90 mm Hg. Blood pressure readings between 120/80 and 140/90 mm Hg are considered prehypertension. Stage one hypertension refers to blood pressure readings between 130/80 and 139/89 mm Hg, while stage two hypertension refers to readings of 140/90 mm Hg or higher.
