The nurse is giving the client preoperative instructions regarding pneumatic compression boots. The nurse explains how these devices work. Which of the following is the best explanation?
1. These devices intermittently inflate to compress the muscles in the legs, which mimics muscle contraction.
2. These devices help to keep the legs warm to increase circulation.
3. These devices are used routinely to remind clients to be active.
4. These devices are only used on obese clients.
These devices intermittently inflate to compress the muscles in the legs, which mimics muscle contraction.
Rationale: The pneumatic compression boots utilize compression to compress the muscles of the legs to mimic muscle contraction and help prevent venous stasis; this minimizes the risk for deep vein thrombosis. While these devices may warm the legs, this is not the primary purpose. The devices are taken off when the client is out of bed for ambulation and activity, so it does not help to remind them to be active. These devices are helpful for all persons, not just those who are obese.
