What is the normal adult blood pressure range?

• A. Approximately 90/60 to 120/80 mmHg.
• B. Approximately 140/90 to 180/110 mmHg.
• C. Approximately 100/70 to 130/85 mmHg.
• D. Approximately 80/40 to 110/70 mmHg.

Answer: (A)

Normal adult blood pressure represents pressures in the arteries when the heart beats and rests, expressed as systolic over diastolic in mmHg. For most healthy adults at rest, a typical normal range is about 90/60 to 120/80 mmHg. This range stays within widely accepted normal limits for both components, avoiding the high values seen with hypertension or the very low values that can cause symptoms of hypotension. The other ranges either show clearly elevated pressures or include diastolic values that are unusually low or borderline high, which aren’t considered normal in routine assessment. So, 90/60 to 120/80 mmHg best fits the normal adult range.
