Which term denotes the presence of excessive bilirubin in the blood causing yellow discoloration of the skin?

• A. Icterus
• B. Infiltrate
• C. Epithelium
• D. Hyperopia

Answer: (A)

The presence of yellow discoloration of the skin from excess bilirubin in the blood is called icterus. Icterus, or jaundice, occurs when bilirubin accumulates because of increased production, impaired liver processing, or obstruction of bile flow, leading to a yellow tint in the skin and eyes. The other terms don't fit this description: infiltrate refers to abnormal substance buildup in tissue, epithelium is the tissue lining surfaces, and hyperopia is farsightedness.
