Which of the following tests should be administered to a client suspected of having diverticulosis?
A. Abdominal ultrasound
B. Barium enema
C. Barium swallow
D. Gastroscopy
Correct Answer: B. Barium enema
A barium enema will cause diverticula to fill with barium and be easily seen on x-ray. A barium enema is a radiographic (X-ray) examination of the lower gastrointestinal (GI) tract. The large intestine, including the rectum, is made visible on X-ray film by filling the colon with a liquid suspension called barium sulfate (barium). Barium highlights certain areas in the body to create a clearer picture.
Option A: The abdominal US can tell more about structures, such as the gallbladder, liver, and spleen, than the intestine. An abdominal ultrasound is a noninvasive procedure used to assess the organs and structures within the abdomen. This includes the liver, gallbladder, pancreas, bile ducts, spleen, and abdominal aorta. Ultrasound technology allows quick visualization of the abdominal organs and structures from outside the body.
Option C: A barium swallow can view upper GI structures. A barium swallow also called an esophagram, is an imaging test that checks for problems in the upper GI tract. The upper GI tract includes the mouth, back of the throat, esophagus, stomach, and first part of the small intestine. The test uses a special type of x-ray called fluoroscopy.
Option D: A gastroscopy is a procedure where a thin, flexible tube called an endoscope is used to look inside the esophagus (gullet), stomach, and the first part of the small intestine (duodenum). It’s also sometimes referred to as an upper gastrointestinal endoscopy. The endoscope has a light and a camera at one end. The camera sends images of the inside of the esophagus, stomach, and duodenum to a monitor.
