Josie is in her last weeks of pregnancy. During a routine check-up, she asks why she is suddenly experiencing swollen feet when she wears knee -high stockings (with a tight elastic band just below the knee). She is confused because an elderly relative wears support stockings to prevent swollen feet, an apparent contradiction. Speculate on a logical explanation for her swelling feet and the
difference between support hose and knee -high stockings.
What will be an ideal response?
The elastic band in one of Josie's stocking is so tight that it constantly compresses her veins just in the area under the elastic. This reduces venous return, increasing pressure below that area and causing fluid to exit her blood. Support stockings are medical devices that apply uniform pressure along their entire length, and so produce no constriction. They increase pressure slightly, continuously aiding venous return much like a muscle pump does intermittently.
