Which ASA physical status category is assigned to a patient with well-controlled hypertension and no other systemic disease?

Question

Accepted Answer

D. ASA II. ## ASA Physical Status Classification Overview

**Key Point:** ASA II is defined as a patient with mild systemic disease that does not limit activity. Well-controlled hypertension without end-organ damage or other comorbidities falls into this category.

## ASA Categories at a Glance

| ASA Class | Definition | Examples |
| --- | --- | --- |
| I | Healthy, no systemic disease | Young, fit patient undergoing elective surgery |
| II | Mild systemic disease, no functional limitation | Well-controlled HTN, mild DM, mild asthma, obesity (BMI 30–40) |
| III | Severe systemic disease with functional limitation | Poorly controlled HTN, severe DM with complications, COPD, CAD |
| IV | Severe systemic disease that is a constant threat to life | Unstable angina, recent MI, severe aortic stenosis, sepsis |
| V | Moribund patient not expected to survive 24 hrs without surgery | Ruptured AAA, massive PE, severe trauma |
| VI | Declared brain-dead organ donor | — |

**High-Yield:** The key distinction between ASA II and ASA III is **functional limitation**. ASA II patients have disease but can perform normal activities; ASA III patients have functional impairment.

**Clinical Pearl:** Well-controlled chronic conditions (HTN on medication, stable asthma, mild DM without complications) are ASA II. The disease must be stable and not limit daily function.

## Why ASA II?

Hypertension is a systemic disease (ASA I excludes all systemic disease), but when well-controlled with no end-organ damage, it does not functionally limit the patient. Therefore, ASA II is appropriate.
