What is the diastolic blood pressure range for an adult?

  1. 50 - 70 mmHg

  2. 60 - 80 mmHg

  3. 70 - 90 mmHg

  4. 80 - 100 mmHg

The correct answer is: 50 - 70 mmHg

The diastolic blood pressure range for a normal adult typically falls between 60 - 80 mmHg. This range reflects the pressure in the arteries when the heart is at rest between beats, which is essential for evaluating cardiovascular health. Values outside this range may indicate underlying health issues; for example, a diastolic pressure lower than 60 mmHg can suggest hypotension, while a reading above 80 mmHg can be indicative of hypertension. Understanding these thresholds is vital for proper assessment and management in clinical practice.
