97-year-old female patient comes for cleaning and checkup. Has controlled hypertension on medication and occasionally drinks red wine. ASA Classification:

Correct answer: B. ASA II

• A. ASA I describes a normal, healthy patient without systemic disease — does not fit this patient with hypertension.
• B. Correct. ASA II describes a patient with mild, well-controlled systemic disease (controlled hypertension) that does not significantly limit activity — fitting this patient.
• C. ASA III describes severe systemic disease that limits activity but is not an immediate threat to life — more severe than this well-controlled presentation.
• D. ASA IV describes severe systemic disease that is a constant threat to life — far more severe than this patient's presentation.
