a. CT scan
b. MRI
c. Lower GI scan
d. Upper GI scan

Answer 1

The correct answer is d. Upper GI scan. It is a fluoroscopic examination of the esophagus, stomach, and duodenum involving the ingestion of barium sulfate as a contrast medium.

Step-by-step explanation:

The correct answer is d. Upper GI scan. An upper GI scan, also known as an upper gastrointestinal series or barium swallow, is a fluoroscopic examination of the esophagus, stomach, and duodenum. In this test, the patient ingests barium sulfate, a contrast medium, which coats the lining of the digestive tract and allows for clearer visualization with the help of X-rays. This procedure is commonly used to diagnose conditions such as acid reflux disease, Crohn's disease, and ulcers.
