The accepted adult normal range for blood pressure is approximately:

Explanation

Normal adult resting BP is roughly systolic 90-120 and diastolic 60-80 mmHg, per AHA fundamentals. Below 90/60 may indicate hypotension and risk of falls or hypoperfusion; readings of 130/80 or above are stage 1 hypertension per the 2017 AHA/ACC guidelines, and a reading at or above 180/120 with symptoms is hypertensive crisis requiring urgent evaluation. CNAs measure accurately and report findings outside the resident's set parameters to the nurse promptly so timely intervention can occur.
