A healthy 24-year-old female patient: Weight 186 lbs, Height 5'5". She has no medical conditions or medications. What is her ASA Physical Status Classification?

Correct answer: B. ASA II

• A. Incorrect. ASA III involves moderate-to-severe systemic disease with functional limitation (e.g., poorly controlled diabetes, morbid obesity BMI >40, COPD).
• B. Correct. ASA II = patient with mild systemic disease or a single risk factor. Per updated ASA guidelines, OBESITY (BMI 30–40) is classified as ASA II — a mild systemic condition without functional limitations. This patient's 186 lbs at 5'5" gives a BMI of ~31 (Class I obesity), making her ASA II.
• C. Incorrect. ASA I is a completely healthy patient with no systemic disease. This patient has a BMI of ~31 (obese) which classifies her as ASA II.
• D. Incorrect. ASA IV involves life-threatening systemic disease.
