Which instruction should the nurse provide to a client who is preparing to have a cystoscopy?

A. Lay prone for 24 hours after the procedure. There is no need for the client to lay prone after a cystoscopy. The client can usually return to normal activities with rest. B. Report any painful urination, blood in urine, or fever. These are potential complications after a cystoscopy, and the client should be instructed to report them promptly to prevent further complications like infection or hemorrhage. C. Avoid strenuous activity and sports for at least 2 weeks. Although rest is encouraged, the specific recommendation about avoiding activity for 2 weeks is not generally required unless specified by the provider. D. Report any allergies to shellfish or iodine. While iodine allergies can affect contrast used in imaging studies, they are not related to cystoscopy procedures, which typically do not use contrast agents.
