What is a stent used for in medical procedures?

• A. To repair a broken bone
• B. To keep a blocked passageway open
• C. To remove excess fluid from the body
• D. To inject medication

Answer: (B)

A stent is a medical device that is specifically designed to keep a blocked passageway open. It is most commonly used in situations where blood vessels or other ducts in the body are narrowed or blocked, such as in cases of coronary artery disease. By placing a stent in the affected area, it provides structural support to maintain the openness of the passageway, ensuring that proper blood flow or other bodily functions can continue without obstruction.

This is a critical intervention in various medical fields, including cardiology and gastroenterology, among others. The placement of a stent can help prevent complications that might arise from narrowed or blocked pathways, such as heart attacks or organ damage.
