Question

a nurse is caring for a client who is scheduled to undergo an esophagogastroduodenoscopy (egd). the nurse should identify that the purpose of this procedure is which of the following?

to visualize colon polyps

to detect an ulceration in the stomach

to identify an obstruction in the biliary duct

to determine the presence of free air in the abdomen

Explanation:

• An esophagogastroduodenoscopy (EGD) is a procedure that uses a scope to examine the esophagus, stomach, and duodenum.
• "To visualize colon polyps" is incorrect as colon polyps are visualized via a colonoscopy (examines the colon).
• "To detect an ulceration in the stomach" is correct because EGD allows visualization of the stomach lining, so it can detect ulcers there.
• "To identify an obstruction in the biliary duct" is incorrect; procedures like ERCP (endoscopic retrograde cholangiopancreatography) or imaging (like MRCP) are used for biliary duct obstructions, not EGD.
• "To determine the presence of free air in the abdomen" is incorrect; free air in the abdomen is detected via X - ray or CT scan, not EGD.

Answer:

B. To detect an ulceration in the stomach (assuming the options are labeled A, B, C, D with A: To visualize colon polyps, B: To detect an ulceration in the stomach, C: To identify an obstruction in the biliary duct, D: To determine the presence of free air in the abdomen)
