Question

Quizplus · Accepted Answer

During a colonoscopy, a long, flexible tube (colonoscope) with a camera on the end is used to examine the inside of the colon. This procedure allows for tissue samples to be obtained through the scope for biopsy or examination, making option B correct. Patients are typically sedated for comfort, not awake and alert. The patient is usually positioned on the left side to facilitate the passage of the colonoscope through the curves of the colon. Air or carbon dioxide, not saline, is used to inflate the colon to provide a better view of the intestinal walls.
