A client with a muscle injury has just returned to the unit from the Physical Therapy department. The client complains to the nurse that the muscles of the shoulder are sore after the exercise in physical therapy
The nurse suggests that the client apply an ordered cold pack for 20 minutes to the shoulder muscles for which of the following reasons? 1. Cooling the muscles will help them to relax and feel less sore.
2. Cold will reduce blood flow and inflammation created by the exercise.
3. Cold packs will bring healing blood to the injured muscle.
4. Cold therapy reduces the risk of infection.
2
Rationale: When injured muscles are exercised, inflammation occurs immediately following the exercise. Cold packs help reduce the inflammation. Heat is then applied after the cold to promote relaxation and perfusion to the muscle. Since sore muscles are not an open wound, infection is not a consideration.
