Current Question (ID: 14558)

Question:

Which one of the following statements is correct regarding blood pressure?

Options:

1. 100/55 mmHg is considered an ideal blood pressure
2. 105/50 mmHg makes one very active
3. 190/110 mmHg may harm vital organs like brain and kidney
4. 130/90 mmHg is considered high and requires treatment

Solution:

Hypertension is the term for blood pressure that is higher than normal (120/80). In this measurement, 120 mm Hg (millimeter of mercury pressure) is the systolic or pumping, pressure and 80 mm hg is the diastolic, or resting pressure. If repeated checks of blood pressure 190/100 mm Hg) of an individual is 140/90 (140 over 90) or higher, it shows hypertension. High blood pressure (190/100 mm Hg) leads to heart diseases and also affects vital organs like brain and kidney.
