Which condition is characterized by swelling due to poor drainage and accumulation of lymph?

• A. Edema
• B. Lymphedema
• C. Hematoma
• D. Phlebitis

Answer: (B)

Lymphedema is characterized by swelling that occurs when the lymphatic system fails to adequately drain lymph fluid, resulting in its accumulation in the body's tissues. This condition can arise due to various factors, including lymph node removal, radiation therapy, infections, or congenital issues with the lymphatic system. It specifically affects the lymphatic system, which plays a crucial role in maintaining fluid balance and immune function.

In contrast, edema refers to a more general swelling that can result from various causes, such as inflammation, injury, or fluid overload. Hematoma is a localized collection of blood outside of blood vessels, typically caused by trauma. Phlebitis involves inflammation of a vein, often accompanied by swelling, but is primarily related to venous issues rather than lymphatic drainage. Thus, lymphedema distinctly identifies the specific problem of lymph fluid drainage.
