Which skin finding is described as increased visibility of oxyhemoglobin due to capillary dilation?

• A. Erythema
• B. Pallor
• C. Cyanosis
• D. Jaundice

Answer: (A)

The main idea here is how skin color changes with blood flow. When capillaries dilate, more blood reaches the surface, and the color of the blood—oxyhemoglobin—becomes more visible, giving the skin a red appearance. That red skin color is erythema. Pallor comes from reduced blood flow or low hemoglobin, making the skin pale. Cyanosis is a bluish tint from higher levels of deoxygenated hemoglobin or poor oxygenation. Jaundice is a yellow tint from bilirubin buildup. So the described finding matches erythema.
