Which documentation format is used when a nurse selects the "WNL" statement for cardiac assessment findings?

The documentation format known as charting-by-exception is utilized when a nurse documents the "WNL" (within normal limits) statement for cardiac assessment findings. This approach streamlines the documentation process by focusing on significant deviations from predefined standards or norms.

In charting-by-exception, only abnormal findings or variations from the standard are documented, while normal results are generally not noted. Therefore, using "WNL" indicates that the cardiac assessment findings fell within the acceptable range and do not require further elaboration. This method emphasizes efficiency in patient care documentation, allowing healthcare providers to quickly identify areas that need attention and prioritize their responses accordingly.

This format contrasts with other documentation types, which may require more detailed descriptions regardless of the findings. For instance, focus charting emphasizes specific patient concerns and interventions, whereas problem-intervention-evaluation provides a structure for tracking problems and their resolutions. Narrative documentation often involves detailed storytelling of the patient's progress and events, leading to more extensive records that document every aspect of a patient's visit or condition.
