In patients with darker skin tones, which areas are typically examined to assess jaundice or poor oxygenation?

• A. Lips, tongue, nail beds, palms, and soles
• B. Ears, cheeks, forehead, and chin
• C. Back, shoulders, arms, and legs
• D. Feet, ankles, wrists, and knees

Answer: (A)

When color changes from jaundice or poor oxygenation are present, areas with thin tissue and rich blood supply show them most clearly, even in darker skin. Jaundice often first appears in mucous membranes, so the lips and tongue can reveal a yellow tint that may not be as obvious on pigmented skin. For cyanosis or reduced oxygenation, the nail beds provide a reliable read on color change and, importantly, allow assessing capillary refill. The palms and soles are also valuable because their vascular surfaces can reflect shifts in color that pigmentation elsewhere might mask. Putting these areas together—lips, tongue, nail beds, palms, and soles—gives the best chance to detect jaundice or hypoxia in patients with darker skin tones.
