A nurse reviewing a client's medical record finds documentation of deep pitting edema. How is this condition classified?

Deep pitting edema refers to a condition where indents or "pits" remain in the skin after pressure is applied, indicating the presence of significant fluid retention in the interstitial spaces. The classification of edema is typically based on the depth and duration of the pitting.

When discussing the scale of pitting edema:

• 1+ edema represents a slight indentation, measuring about 2 mm, and the indentation disappears quickly.

• 2+ edema is deeper, measuring about 4 mm, with the indentation lasting for a few seconds.

• 3+ edema involves a more pronounced indentation of approximately 6 mm, with the indentation lasting for about 10-12 seconds.

• 4+ edema is the most severe classification, indicating a very deep indentation of 8 mm or more, with the pit remaining for a prolonged period, usually more than 20 seconds.

The documentation of "deep pitting edema" suggests that the pitting is significant and long-lasting, which is characteristic of 3+ edema. This level indicates a considerable degree of fluid accumulation that warrants careful monitoring and management, making it the correct classification in this scenario.
