Question

Hypertension is the elevation of blood pressure above normal. Which of the following is generally accepted as hypertension?

• A. Systolic BP \(>\) 120 & Diastolic BP \(>\) 60 mmHg
• B. Systolic BP \(>\) 110 & Diastolic BP \(>\) 70 mmHg
• C. Systolic BP \(>\) 90 & Diastolic BP \(>\) 140 mmHg
• D. Systolic BP \(>\) 140 & Diastolic BP \(>\) 90 mmHg

Hint:

Hypertension is typically diagnosed when the systolic pressure is greater than 140 mmHg or the diastolic pressure is greater than 90 mmHg.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Blood pressure (BP) is measured in millimeters of mercury (mmHg) and consists of two numbers: Systolic (pressure when heart beats) and Diastolic (pressure when heart rests).
Step 2: Detailed Explanation:
- Normal BP: Typically considered around 120/80 mmHg.
- Pre-hypertension/Elevated: 120-129 / < 80 mmHg.
- Hypertension (Stage 2/General clinical threshold): Most medical organizations traditionally define clinical hypertension when the reading is consistently at or above 140/90 mmHg.
Option (A) and (B) show values close to or within the normal range.
Option (C) shows a Diastolic value (140) higher than the Systolic (90), which is physiologically incorrect for a standard BP reading.
Step 3: Final Answer:
Hypertension is generally accepted as a blood pressure reading higher than 140/90 mmHg.
