Which scale is described as measuring functional status from 100 to 0?

• A. Karnofsky Performance Scale
• B. Palliative Performance Scale
• C. ADL
• D. IADL

Answer: (A)

The main idea here is recognizing scales that quantify overall functional ability on a 0 to 100 spectrum. The Karnofsky Performance Scale is designed specifically for this, rating a person’s ability to carry out ordinary tasks from 100, meaning normal functioning with no complaints or symptoms, down to 0, meaning death. This simple, whole-status metric makes it a primary tool for gauging how well someone can work, care for themselves, and tolerate treatment. While another scale used in palliative care also uses a 0–100-like format, the Karnofsky scale is the classic reference for functional status described in this way. ADL and IADL, though important for assessing independence in daily activities, are not expressed on a single 0–100 functional status scale.
