Klose Training Lymphedema 101 Practice Test

Edema occurs when fluid collects in the tissues because something is disturbing the body’s normal fluid balance or lymphatic drainage. Because many diseases—such as heart failure, kidney disease, liver disease, venous insufficiency, or inflammatory processes—can disrupt forces that move fluid out of vessels or impair lymphatic return, edema is typically a sign pointing to an underlying problem rather than a disease in itself. Treating edema effectively means addressing that root cause and also applying measures to reduce swelling. The other ideas aren’t accurate for this concept. Lymphedema is a specific condition caused by impaired lymphatic flow, not just a symptom, so saying it’s only a symptom misses its distinct nature. Edema isn’t unrelated to disease—it's commonly linked to disease processes. And lymphedema isn’t caused solely by kidney failure; it stems from lymphatic dysfunction, which often has different causes.
