What is the normal blood pressure of an adult?

Correct option is D

The normal blood pressure of a healthy adult is considered to be 120/80 mm Hg, where:
120 mm Hg is the systolic pressure (the pressure in the arteries when the heart beats or contracts), and 80 mm Hg is the diastolic pressure (the pressure in the arteries when the heart rests between beats). This value is accepted globally as the ideal or optimal blood pressure. Blood pressure above or below this range can indicate health issues. A persistent reading above 140/90 mm Hg is considered hypertension, while below 90/60 mm Hg may indicate hypotension.
Information Booster:
· Systolic Pressure: Represents the force the heart exerts on the artery walls during a beat.
· Diastolic Pressure: Represents the pressure in the arteries when the heart is at rest.
· Blood pressure is measured in millimeters of mercury (mm Hg).
· Normal blood pressure can slightly vary with age, activity, stress, and overall health.
· High blood pressure is a major risk factor for heart disease, stroke, and kidney failure.
Additional Knowledge:
· 150/100 mm Hg: This reading indicates Stage 2 Hypertension, which is a serious condition. Persistent blood pressure at or above this level increases the risk of cardiovascular complications. Lifestyle changes and medication may be necessary to bring it down.
· 140/90 mm Hg: This is the threshold for Stage 1 Hypertension. People with such readings are at risk of developing complications like heart attack, stroke, and organ damage if left unmanaged. It is a red flag requiring medical attention.
· 100/60 mm Hg: This is considered low blood pressure (hypotension). Though not always dangerous, it can cause symptoms like dizziness, fainting, blurred vision, and fatigue. In some cases, it may indicate underlying health issues such as dehydration or hormonal disorders.
