Answer and explanation
Correct answer: C. Yellowish pigmentation of the skin, sclera, and tissues due to hyperbilirubinemia
- Step 1: Bilirubin is a yellow breakdown product of normal heme catabolism. Step 2. When serum total bilirubin exceeds 2.5-3.0 mg/dL, bilirubin deposits in elastin-rich sclera and skin, causing yellow jaundice (icterus). Answer: Yellowish pigmentation of the skin, sclera, and tissues due to hyperbilirubinemia. Why not the others: Bluish nail beds is cyanosis; Redness and swelling is inflammation; Palmar crease hyperpigmentation is seen in Addison's disease.
