A client insists on having a wart treated by rubbing a cut potato on the wart rather than the injection that is currently being used in practice. The nurse realizes additional discussion is needed with the client to understand the request. The nurse speaks with the client and realizes the client has a needle phobia. Taking this into account, the nurse mentions that cryotherapy may be another option for wart removal, and that while it doesn't have as high a success rate as the injection being proposed, studies indicate that it is still fairly successful.
