What is the normal range for adult blood pressure?

• A. 80/40 mmHg to 100/60 mmHg
• B. 90/60 mmHg to 120/80 mmHg
• C. 100/70 mmHg to 130/90 mmHg
• D. 110/75 mmHg to 140/85 mmHg

Answer: (B)

The correct range for normal adult blood pressure is identified as 90/60 mmHg to 120/80 mmHg, which reflects a healthy blood pressure range according to standard medical guidelines. Typically, blood pressure is expressed in a fraction with two numbers: systolic pressure (the pressure during heartbeats) over diastolic pressure (the pressure when the heart rests between beats).

The normal range indicates that systolic pressure can fall anywhere from 90 to 120 mmHg, while diastolic pressure ranges from 60 to 80 mmHg. A reading within this range typically suggests that the heart and blood vessels are functioning efficiently, without placing excess strain on the cardiovascular system.

Blood pressure readings outside this range can indicate potential health issues; for instance, readings consistently above 120/80 mmHg may signify prehypertension or hypertension, while readings below 90/60 mmHg can indicate hypotension. Understanding these ranges is vital for assessing cardiovascular health and making informed clinical decisions.
