What is required in the preparation for a colonoscopy?

The preparation for a colonoscopy is crucial to ensure that the gastrointestinal tract is adequately cleaned out, which allows for clear visualization of the colon during the procedure. Bowel preparation with Golytely, which is a polyethylene glycol electrolyte solution, is a standard method used. This solution helps to thoroughly cleanse the bowel of all stool, which is essential for preventing any obstructions to viewing during the exam.

In this context, a high-fat diet would not be appropriate as it could lead to inadequate bowel clearance. Additionally, while a clear liquid diet may be part of the preparation, consuming red juices is typically avoided because they can stain the lining of the bowel and may interfere with results. Remaining NPO (nothing by mouth) for a certain period prior to the procedure is also part of preparation but is generally only for a short time frame. Overall, bowel preparation with Golytely is specifically designed to ensure a clean bowel, making it the correct answer for this question.
