Special Patient Populations Practice Test

Understanding blood pressure thresholds helps determine whether a dental patient can safely proceed with routine care. Normal for evaluating cardiovascular risk is a reading under 120 systolic and under 80 diastolic. This level corresponds to low short‑term risk and is generally considered safe for nonemergency dental treatment without special precautions. Readings in the 120–139 systolic or 80–89 diastolic range are considered elevated and typically warrant a recheck and possible medical consultation before elective care. Blood pressures of 140/90 or higher indicate hypertension, which usually requires medical clearance and may lead to postponing nonurgent procedures or adjusting care. A value like 130/85 falls into the elevated/early hypertension range, not normal.
