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

A. Clients should be instructed to report any concerning symptoms following a cystoscopy, as they can indicate complications such as infection or injury. B. Laying prone is not a typical post-procedure requirement; clients may resume normal positions as tolerated unless otherwise directed. C. Avoiding strenuous activity may be advisable, but specific recommendations can vary based on the provider’s orders. D. While iodine allergies may be relevant if contrast dye is used, cystoscopy generally does not involve this.
