For a patient with a primary lymphatic disorder of a lower extremity, which intervention is MOST appropriate?

• A. Elevation of the extremity
• B. Manual drainage
• C. Immobilization of the extremity
• D. Thermotherapy

Answer: (B)

Managing edema from a primary lymphatic disorder relies on actively helping lymph move out of the affected limb. Manual lymph drainage is a gentle, specialized massage technique designed to stimulate lymphatic vessels and redirect lymph toward functioning lymph nodes. By promoting this active drainage, it reduces interstitial fluid buildup and swelling, improving comfort and function in the leg.

Elevating the limb can help lessen swelling temporarily but doesn’t actively move lymph; immobilizing the limb can trap fluid and worsen stiffness; applying heat (thermotherapy) may cause vasodilation and increased fluid accumulation. So the most effective choice is manual lymph drainage, which directly enhances lymphatic transport.
