Question 1 of 5
What procedure examines a portion of the large intestine with an endoscope?
Correct Answer: B
Rationale: Sigmoidoscopy is the correct answer because it specifically examines the sigmoid colon located in the descending colon using an endoscope inserted through the rectum. This procedure captures video and images of the large intestine's lining, helping in the diagnosis of conditions like inflammatory bowel disease or colorectal cancer. Colposcopy, on the other hand, is a procedure for examining the cervix and vagina, not the large intestine. Upper GI involves capturing images of the esophagus and stomach, focusing on the upper gastrointestinal tract, not the large intestine. Cardiac catheterization is a procedure that involves threading a thin instrument through the femoral artery to the heart, used for cardiac interventions and not related to examining the large intestine.
