In chart documentation, WNL stands for which phrase?

• A. Within No Limits
• B. Within Normal Levels
• C. Well Normal Limits
• D. Within Normal Limits

Answer: (D)

WNL is shorthand for Within Normal Limits. In charting, this phrase is used to indicate that a lab value, vital sign, or exam finding falls within the established reference range and there’s no abnormality detected. It’s preferred because it’s concise and universally understood in medical documentation. The other options aren’t standard phrases used in charts—they could be confusing or misleading, whereas Within Normal Limits clearly communicates that everything is within expected bounds. When results are normal, you’ll typically see WNL noted; if an value is off, the chart will show the actual number or a specific abnormal finding.
