A patient's blood pressure reading is 146/90 mmHg. According to the 2017 ACC/AHA guidelines, how should this blood pressure be categorized?
Show answer and explanation
Correct answer: B. Hypertension Stage 2 (≥140/≥90 mmHg)
According to the 2017 American College of Cardiology/American Heart Association (ACC/AHA) hypertension guidelines: Normal: <120/<80 mmHg; Elevated: 120-129/<80 mmHg; Stage 1 Hypertension: 130-139 or 80-89 mmHg; Stage 2 Hypertension: ≥140 or ≥90 mmHg. A reading of 146/90 mmHg meets the threshold for Stage 2 hypertension (systolic ≥140 and/or diastolic ≥90). The dental significance: patients with Stage 2 hypertension (≥160/100) should not receive elective dental care until blood pressure is better controlled; patients at 140-159/90-99 should be monitored and may receive routine dental care with stress-reduction protocols.
