- AYou can stop drinking clear liquids once the bowel movements are clear.
- BIt is important to drink all of the prescribed bowel preparation solution.
- CYou may eat a light breakfast on the morning of the procedure.
- DYou should take all your regular medications as usual.
Show answer & explanationAnswer & explanation
Correct answer: B. It is important to drink all of the prescribed bowel preparation solution.
Adequate bowel preparation is crucial for a successful colonoscopy to ensure clear visualization of the colon lining. Drinking all of the prescribed solution, even if bowel movements appear clear, ensures the entire colon is thoroughly cleansed.
Why the other options are wrong
- A. Clients should continue clear liquids as instructed, usually until 2-4 hours before the procedure, regardless of bowel movement clarity, to prevent dehydration.
- C. Clients should be NPO (nothing by mouth) or on clear liquids only on the day of the procedure, not a light breakfast.
- D. Clients are usually instructed to hold certain medications (e.g., anticoagulants, iron supplements) before a colonoscopy.
