Final answer:
The resting blood pressure that represents a healthy individual is 120/80 mmHg. This measurement contains two numbers, the systolic and diastolic pressures, indicative of the heart's function during contraction and relaxation phases respectively. Blood pressures consistently above 130/80 mmHg are considered hypertensive.
So, the correct answer is 1) 120/80 mmHg.
Step-by-step explanation:
A healthy person's resting blood pressure is most accurately represented as 120/80 mmHg. This measurement refers to the systolic pressure (120 mm Hg) and the diastolic pressure (80 mm Hg). Systolic pressure is the maximum pressure in the arteries when the heart contracts, while diastolic pressure is the minimum pressure in the arteries when the heart is at rest between beats.
New guidelines from health authorities classify normal blood pressure as less than 120/80 mm Hg. Blood pressure readings that are consistently 130/80 mm Hg or higher are recognized as hypertension, which requires medical attention due to the risks of heart disease and stroke.
So, the correct answer is 1) 120/80 mmHg.
