What instruction should a nurse provide to a client returning home after an arthroscopy of the shoulder?

The instruction to report fever or redness at the site is crucial because it helps in monitoring for potential complications associated with arthroscopy, such as infection or inflammation. After a surgical procedure like an arthroscopy, the risk of infection at the incision site is a pertinent concern. Signs of infection typically include fever, increased redness, swelling, and warmth at the surgical site. Being vigilant about these symptoms enables prompt medical intervention, which can prevent further complications and promote better outcomes.

While limiting physical activity, keeping the arm elevated, and avoiding all activities for a month may also be reasonable guidelines to consider in recovery, they do not directly address immediate warning signs that the client should report to their healthcare provider. The focus on reporting potential signs of infection is a critical part of post-operative care instructions and ensures the client's safety as they recover.
