A patient with blood pressure of 142/95 mmHg. What is the CORRECT ASA classification?

  1. ASA III (BP 160/100 to 180/109 is ASA III; 142/95 is Stage 1–2 HTN = ASA II–III; sources vary — most classify ≥140/90 as ASA III)
  2. ASA II (140/90 threshold = ASA III per ADA)
  3. ASA IV
  4. ASA I
Show answer and explanation

Correct answer: A. ASA III (BP 160/100 to 180/109 is ASA III; 142/95 is Stage 1–2 HTN = ASA II–III; sources vary — most classify ≥140/90 as ASA III)

  • A. Correct. BP 142/95 falls into Stage 2 hypertension (per AHA 2017: Stage 2 = ≥140/90). Per ASA guidelines: ASA II = controlled hypertension (<160/100); ASA III = uncontrolled HTN (160–179/100–109) OR with organ damage. At 142/95, most boards and review sources classify this as ASA III for dental purposes, especially if the history suggests uncontrolled hypertension.
  • C. ASA IV implies a life-threatening condition — 142/95 is not life-threatening.
  • D. ASA I is a healthy patient with no systemic disease.
