Question

Normal diastolic blood pressure ranges from (in mm Hg):

• A. 0–30
• B. 30–60
• C. 60–90
• D. 90–120

Hint:

Think of "D" for Diastolic as "Down time" when the heart rests — a healthy diastolic range is between 60 and 90 mm Hg.

Answer 1

The Correct Option is C

Blood pressure is typically recorded as two numbers: systolic over diastolic pressure.
- The systolic pressure is the higher value and indicates the pressure in the arteries when the heart beats.
- The diastolic pressure is the lower value and shows the pressure when the heart is resting between beats.
According to standard clinical guidelines:
- A normal diastolic blood pressure generally falls between 60 mm Hg and 90 mm Hg.
- A value below 60 mm Hg is often considered low (hypotension), and above 90 mm Hg may be an indication of hypertension.
Thus, the correct normal range for diastolic blood pressure is 60–90 mm Hg.
