A nurse is reinforcing teaching with a client who is scheduled to have a colonoscopy in 1 week. Which of the following client statements indicates an understanding of the teaching?

Rationale: A. "I will follow a full-liquid diet the day before the procedure.": Clients are typically instructed to follow a clear-liquid, not full-liquid, diet the day before a colonoscopy. Clear liquids like broth, gelatin, and clear juice help ensure the colon is clean for optimal visualization. B. "I'll have my friend drive me home after the procedure.": Sedation is usually administered during a colonoscopy, which impairs alertness and coordination. Having a responsible adult to drive the client home is necessary and reflects appropriate understanding of post-procedure safety. C. "I can expect rectal bleeding for a week after the procedure”: Rectal bleeding after a colonoscopy is not expected and could indicate complications such as a perforation or polyp removal site bleeding. Any persistent or heavy bleeding should be reported immediately. D. "This procedure will take place while I’m under general anesthesia.”: Colonoscopies are generally performed under moderate (conscious) sedation, not general anesthesia. Clients remain semi-awake but relaxed and unaware, making this statement inaccurate.
