What is the normal systolic/diastolic blood pressure range for an adult when taking vitals?

• A. Approximately 90-120 systolic over 60-80 diastolic
• B. 100-140 systolic over 70-90 diastolic
• C. 110-130 systolic over 60-70 diastolic
• D. 130-150 systolic over 85-95 diastolic

Answer: (A)

Understanding normal blood pressure means looking at two numbers: the systolic (top) pressure, which measures the force in the arteries during a heartbeat, and the diastolic (bottom) pressure, which measures the pressure when the heart rests between beats. For an adult, a typical healthy range is around 90–120 for the systolic value and 60–80 for the diastolic value. Readings within this range usually indicate normal blood pressure and a lower risk of cardiovascular problems.

If the numbers rise beyond this range, it may indicate elevated blood pressure or hypertension, and readings significantly above normal warrant medical attention. If the numbers drop far below this range, that can indicate hypotension, which can also be a concern depending on symptoms and context.

When taking vitals, accuracy is as important as the target range. Ensure the person is seated with back supported, feet uncrossed and flat, the arm supported at heart level, and a properly fitting cuff. Have the person rest for a few minutes and avoid caffeine, nicotine, or talking just before measurement. This helps ensure the reading reflects true resting blood pressure.
