Which one indicates the hypertension ?

Options

A. 120/80 mmHg
B. 80/120 mmHg
C. 140/90 mmHg
D. 40/60 mmHg

Answer

To determine which blood pressure readings indicate hypertension, we need to understand the classifications of blood pressure. Here’s a step-by-step breakdown:

### Step 1: Understand Normal Blood Pressure
Normal blood pressure for a healthy adult is typically defined as being less than 120/80 mmHg. This means:
- Systolic pressure (the top number) is less than 120 mmHg.
- Diastolic pressure (the bottom number) is less than 80 mmHg.

### Step 2: Identify Pre-Hypertension
Pre-hypertension is a condition where blood pressure readings are higher than normal but not yet in the hypertension range. The range for pre-hypertension is:
- Systolic pressure between 120-139 mmHg.
- Diastolic pressure between 80-89 mmHg.

### Step 3: Define Hypertension
Hypertension is classified into two stages:
- **Stage 1 Hypertension**: This is indicated by blood pressure readings of:
- Systolic pressure between 140-159 mmHg.
- Diastolic pressure between 90-99 mmHg.

- **Stage 2 Hypertension**: This is indicated by blood pressure readings of:
- Systolic pressure of 160 mmHg or higher.
- Diastolic pressure of 100 mmHg or higher.

### Conclusion
Based on the classifications:
- Hypertension is indicated by blood pressure readings that are **140/90 mmHg or higher**.
