When monitoring blood pressure, which of the following readings is classified as hypotension?

Hypotension, or low blood pressure, is generally defined as a blood pressure reading that is lower than the normal range. While individual thresholds for hypotension can vary, a common standard is a systolic reading below 90 mmHg and/or a diastolic reading below 60 mmHg.

In this context, a reading of 90/60 falls below the typical normal range. Specifically, the systolic pressure of 90 is at the lower limit commonly recognized for hypotension. This can indicate that the body may not be receiving adequate blood flow, which can lead to symptoms such as dizziness or fainting.

In contrast, the other readings provided—100/70, 120/80, and 140/90—are all within the normal or elevated ranges. This reinforces the understanding that any reading at or above the commonly accepted threshold typically does not classify as hypotension. Therefore, the choice indicating 90/60 accurately identifies a hypotensive state, aligning with medical guidelines for blood pressure classification.
