Certified Wound Ostomy Nurse (CWON) Practice Test

What is lymphedema characterized by?

1. Accumulation of protein-rich fluid in tissues

2. Bloody fluid in the cavities of the body

3. Excess accumulation of lymphatic vessels without edema

4. Inflammation of lymph nodes only

The correct answer is: Accumulation of protein-rich fluid in tissues

Lymphedema is characterized by the accumulation of protein-rich fluid in tissues, which occurs due to a disruption in the lymphatic system. This condition typically arises when lymphatic vessels are blocked or damaged, leading to an impaired ability to transport lymph fluid effectively. As a result, the fluid accumulates in the interstitial spaces, causing swelling, which may be evident in the extremities or other areas of the body. Protein-rich fluid accumulation is particularly significant because it can lead to further complications, including tissue fibrosis and an increased risk of infections. This characteristic underlines the importance of managing lymphedema effectively to improve patient outcomes and quality of life. Understanding the nature of the fluid involved and the mechanisms behind its accumulation is vital for those in wound and ostomy care, enabling them to provide appropriate interventions and support.
