What is considered the normal adult blood pressure reading?

A normal adult blood pressure reading is considered to be around 120/80 mmHg. This measurement indicates that the systolic pressure, which occurs when the heart beats, is 120 mmHg, and the diastolic pressure, which occurs when the heart is at rest between beats, is 80 mmHg. This reading falls within the ideal range established by health organizations and is often used as a benchmark for assessing cardiovascular health in adults.

Blood pressure readings can vary depending on various factors like age, activity level, and health conditions, but the 120/80 mmHg mark is a standard reference point. When blood pressure is significantly above or below these values, it can indicate health issues that may need further evaluation or management, such as hypertension or hypotension.

In the context of the other choices, while readings like 110/70 and 130/90 are within a generally acceptable range for some adults, they do not represent the universally recognized standard. The reading of 140/85 is commonly seen as elevated and might suggest prehypertension, which requires monitoring or lifestyle changes.
