Engage Fundamentals RN Vital Signs Practice Test

Low blood pressure is diagnosed when the systolic value is below 90 mm Hg or the diastolic value is below 60 mm Hg. The reading 88/54 mm Hg falls below both normal thresholds, so it indicates hypotension. The other readings stay within typical or high ranges (around normal or elevated for some guidelines), so they do not represent hypotension. In real practice, symptoms and repeated measurements are considered to confirm hypotension, since numbers can vary with posture, activity, and measurement conditions.
