What is a contracture?

1. Shortening and stiffening of muscles

2. Increased flexibility of joints

3. Swelling of tissues

4. Painful joint condition

The correct answer is: Shortening and stiffening of muscles

A contracture is defined as the shortening and stiffening of muscles, tendons, or other soft tissues, which can lead to decreased or limited range of motion in joints. This condition often occurs as a result of prolonged immobility, injury, or certain medical conditions. Contractures can significantly impact a person's ability to move freely and may lead to further complications if not addressed, such as muscle weakness or joint stiffness. In contrast, the other options refer to different physiological conditions. Increased flexibility of joints indicates good joint function and does not relate to the restrictive nature of a contracture. Swelling of tissues relates more to inflammation or fluid retention, which is a different process than the structural changes seen in contractures. A painful joint condition may involve issues like arthritis but does not capture the specific mechanical changes that characterize a contracture. Understanding contractures and their implications is important in nursing care to prevent complications in patients who may be at risk.
