Which term describes looking inside the body using an instrument called an endoscope?

• A. Ostomy
• B. Stenosis
• C. Infarct
• D. Endoscopy

Answer: (D)

The concept being tested is terminology for procedures that visualize the inside of the body. Looking inside with an instrument called an endoscope is endoscopy. An endoscope is a long, flexible tube with a light and camera that lets clinicians inspect internal surfaces and cavities, such as the digestive tract, airways, or joints, and can be used for some therapeutic actions. The other terms describe different ideas: an ostomy is a surgically created opening for waste to exit the body; stenosis means a narrowing of a passage; infarct refers to dead tissue due to lack of blood supply. So the term for looking inside using an endoscope is endoscopy.
