What are the four normal ranges of adult blood pressure?

The normal ranges of adult blood pressure are defined according to guidelines that help categorize blood pressure levels for health assessments. The correct response indicates a range that is widely recognized as normal for adults, falling between 90/60 mmHg and 120/80 mmHg. This range signifies optimal cardiovascular health and is used as a benchmark in clinical settings.

Blood pressure is measured with two values: systolic pressure (the top number, representing the pressure when the heart beats) and diastolic pressure (the bottom number, representing the pressure when the heart rests between beats). A normal blood pressure reading is typically considered to be anywhere from 90/60 mmHg up to 120/80 mmHg, which is important for healthcare providers when assessing patients.

Other ranges listed, while they might reflect various stages of blood pressure, do not align with the standard definition of normal. The combination of the values in the correct range ensures better cardiovascular function and reduces the risk of heart disease and complications associated with hypertension or low blood pressure.
