What does the ASA physical status classification range indicate?

• A. ASA I–VI; I healthy, II mild systemic disease, III severe systemic disease, IV life-threatening disease, V moribund not expected to survive without the procedure, VI brain-dead organ donor.
• B. ASA I–V; I healthy, II mild systemic disease, III severe systemic disease, IV life-threatening disease, V moribund not expected to survive without the procedure.
• C. ASA I–VI; I healthy, II mild systemic disease, III severe systemic disease, IV life-threatening disease, V moribund not expected to survive without the procedure.
• D. ASA II–VI; II mild systemic disease, III severe systemic disease, IV life-threatening disease, V moribund not expected to survive without the procedure, VI brain-dead organ donor.

Answer: (A)

The main idea here is how the ASA physical status ranges describe a patient’s preoperative health, from completely healthy to someone who is a donor for organ transplantation. The full range goes from I to VI, with each level defined: I is a healthy patient; II has mild systemic disease; III has severe systemic disease; IV has a life-threatening systemic disease; V is moribund and not expected to survive without the procedure; and VI is a brain-dead patient whose organs are being removed for donor purposes. The correct choice matches this complete sequence and its definitions, including the brain-dead donor category. The other options narrow or omit part of the range or misstate what's included, which is why they’re not as accurate.
