Final answer:
When working on a swollen upper extremity, it is generally not necessary to decongest the trunk on the same side. Instead, techniques such as elevation, compression, and manual lymphatic drainage can be effective in reducing the swelling and improving lymphatic flow.
Step-by-step explanation:
When working on a swollen upper extremity, it is generally not necessary to decongest the trunk on the same side.
Since the lymphatic system is a network that drains fluid from various parts of the body, including the upper extremities, trunk, and lower limbs, decongesting the trunk would not directly impact the swelling in the upper extremity.
Instead, focusing on techniques such as elevation, compression, and manual lymphatic drainage for the swollen upper extremity can help reduce the swelling and improve lymphatic flow in that specific area.
