A nurse is explaining the purpose of a colonoscopy to a client suspected of having gastrointestinal cancer. What information should the nurse provide?
"A colonoscopy helps in obtaining tissue samples for biopsy and assessing the entire colon for abnormalities."
"This test uses sound waves to create images of the gastrointestinal tract and detect any tumors or growths."
"Colonoscopy primarily examines the esophagus to identify any cancerous lesions."
"It involves swallowing a small camera that captures images as it travels through the gastrointestinal tract."
The Correct Answer is A
A) Correct. A colonoscopy involves the insertion of a flexible tube with a camera through the rectum to visualize the colon and obtain tissue samples for biopsy.
B) Incorrect. The description provided pertains more to an ultrasound or endoscopic ultrasound (EUS) rather than a colonoscopy.
C) Incorrect. Colonoscopy primarily examines the colon, not the esophagus.
D) Incorrect. This description aligns more closely with a capsule endoscopy, where a camera is swallowed to capture images, but it does not allow for biopsy.
