Final answer:
The intermittent pneumatic compression device is used to facilitate the movement of lymphatic fluids and reduce lymphedema in Florence Flinstone's left arm, improving circulation rather than directly addressing pain, infection prevention, or muscle strength.
Step-by-step explanation:
The purpose of using an intermittent pneumatic compression device in the case of Florence Flinstone, who is suffering from lymphedema in her left arm following a radical mastectomy with axillary lymph node resection, is primarily to improve blood circulation within the affected limb. However, the main goal is to facilitate the movement of lymphatic fluids to reduce the swelling caused by the lymphedema. While improving blood circulation can contribute to reducing pain, preventing infection, and potentially aiding in muscle maintenance, these are not the primary intended effects of such treatment in this context.
