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

A. Avoid strenuous activity and sports for at least 2 weeks: This restriction is not necessary after a cystoscopy; mild activity restrictions may apply for 24–48 hours, but not for weeks. B. Lay prone for 24 hours after the procedure: There is no need to lie prone post-cystoscopy. Clients are typically allowed to resume normal positioning and activity shortly after the procedure. C. Report any painful urination, blood in urine, or fever: These symptoms may indicate infection or trauma related to the procedure and should be reported promptly for evaluation and possible treatment. D. Report any allergies to shellfish or iodine: These allergies are relevant for procedures involving iodinated contrast dye, such as CT scans or angiography, but not typically for a cystoscopy, which uses no contrast.
