The Karnofsky Performance Scale measures functional status from 100 to 0.

• A. Measures cognitive function only.
• B. Scores emotional well-being only.
• C. Measures functional status from 100 (healthy) to 0 (dead).
• D. Assesses pain severity.

Answer: (C)

Functional status and independence are what this scale measures. The Karnofsky Performance Scale is used to rate how well a person can carry on normal activities and care for themselves, expressed as a percentage from 100% (normal functioning with no symptoms) down to 0% (death). This makes it a broad gauge of overall functional capacity, not focused on a single domain. It does not target cognitive function, emotional well-being, or pain severity—those areas are assessed by other tools. So the description that it measures functional status from 100 to 0 accurately captures its purpose and range.
