How is blood pressure recorded if the systolic pressure is 135 and the diastolic pressure is 70?

Blood pressure is recorded as a ratio of systolic pressure over diastolic pressure, with systolic being the upper number and diastolic being the lower number. In this case, the systolic pressure is 135 and the diastolic pressure is 70. Therefore, the correct way to express this measurement is as 135 over 70, which is written as 135/70.

This format is standard in clinical practice, allowing healthcare providers to quickly assess an individual's cardiovascular health. The measurement is also often followed by the unit of pressure, mmHg (millimeters of mercury), but in this case, only the numbers are specified in the correct answer choice.

In summary, the correct recording of blood pressure is critical for accurate communication and monitoring in healthcare.
