What should a nurse do for a client experiencing irritation from a cast?

When a client experiences irritation from a cast, placing small pieces of tape over the rough edges is an effective approach to alleviating discomfort. This method acts as a protective barrier, cushioning the skin from the abrasive areas of the cast. It can help prevent further skin irritation and protect any areas that may be prone to rubbing or pressure, creating a more comfortable experience for the client.

Using tape is a simple and immediate solution that a nurse can implement without needing to make significant alterations to the cast itself. It provides a quick means of addressing the irritation while allowing the cast to remain intact, which is crucial for proper immobilization and healing of the underlying injury.

The other responses may not effectively address the issue. Reapplying the cast could be unnecessary if the fundamental structure remains intact and only irritation is present. Smoothing rough edges with a nail file is typically not advisable due to the risk of compromising the integrity of the cast. Bivalving the cast may be appropriate in certain situations, particularly if it is too tight or causing severe issues, but it is a more invasive procedure that should be considered only if simpler measures, such as using tape, do not alleviate the irritation.
