What condition is associated with swelling due to fluid accumulation?

• A. Effusion
• B. Crepitus
• C. Benign
• D. Acute

Answer: (A)

The condition associated with swelling due to fluid accumulation is known as effusion. An effusion occurs when excess fluid builds up in a particular space in the body, such as in a joint (as in joint effusion), in the pleural cavity (pleural effusion), or any other area where fluid can collect. This accumulation results in noticeable swelling and can lead to discomfort, pain, and decreased mobility or function depending on the location of the effusion.

The other terms do not specifically relate to the accumulation of fluid. Crepitus refers to a grating, crackling, or popping sound that can occur in joints or with certain movements, often related to underlying conditions like arthritis. Benign refers to a non-cancerous condition or growth and does not pertain to fluid accumulation or swelling. Acute describes a medical condition that is severe and sudden in onset but does not specifically indicate swelling due to fluid. Therefore, effusion is the most accurate term for this phenomenon.
