Inflammation of a vein.

Inflammation of a vein.

• A. Phlebitis
• B. Electrolyte
• C. Duodenum
• D. Pericardium

Answer: (A)

Inflammation of a vein is described by the term phlebitis, which combines phleb- meaning vein with -itis meaning inflammation. This naming directly indicates that the condition involves an inflamed vein. The other terms refer to different things—electrolyte is a mineral ion in body fluids, the duodenum is part of the small intestine, and the pericardium is the membrane around the heart—so they don’t describe inflammation of a vein. If there’s also a clot involved, you might hear thrombophlebitis, but the base concept remains inflammation of a vein.
