What term indicates a procedure for aspiration or puncture for fluids?

• A. -desis
• B. -centesis
• C. -ectomy
• D. -plasty

Answer: (B)

The term that indicates a procedure for aspiration or puncture to obtain fluids is "-centesis." This suffix is used in medical terminology to describe various procedures where a needle is used to access a body cavity, space, or organ in order to withdraw a sample of fluid. Common examples include amniocentesis, which involves puncturing the amniotic sac to collect amniotic fluid, and paracentesis, where fluid is removed from the abdominal cavity.

In contrast, the other options refer to different types of procedures. The suffix "-desis" refers to binding or surgical fixation, such as arthrodesis which is the surgical fusion of a joint. The suffix "-ectomy" denotes surgical removal, as seen in appendectomy, which is the removal of the appendix. Lastly, "-plasty" refers to surgical repair or reconstruction, such as rhinoplasty, which is a cosmetic surgical procedure to reshape the nose. Therefore, "-centesis" specifically points to the aspiration or puncture of fluids, making it the accurate term in this context.
