OSCE On-Ground Practice Test

The main idea is that pitting edema is detected when pressing on the skin leaves a dent that persists for a moment before the skin refills. A positive pitting edema sign means the depression does not refill rapidly and the skin contour slowly returns to normal. That description matches a depression that remains after applying pressure and then gradually refills, indicating interstitial fluid accumulation. If the skin rebounds quickly (or there’s no indentation), that points away from edema, and an indentation that disappears quickly isn’t consistent with pitting edema.
