What is the recommended patient position during a thoracentesis?

• A. Upright sitting position on the side of the bed, leaning forward over a bedside table, arms on pillows.
• B. Supine.
• C. Prone.
• D. Left lateral decubitus.

Answer: (A)

Positioning for a thoracentesis centers on giving safe, easy access to the pleural space while keeping the patient comfortable. The best choice is an upright seated posture with the patient leaning forward over a bedside table and arms supported. This stance widens the intercostal spaces, stabilizes the upper body to prevent movement, and allows pleural fluid to collect in a predictable area near the base of the lungs, making a needle entry safer and more direct. It also helps keep the diaphragm lower and out of the needle path, reducing the risk of hitting abdominal organs. If the patient can’t sit up, alternative positions may be used, but they make access more difficult and can increase risk.
