A newborn infant has Down syndrome. During the skin assessment, the nurse notices a transient mottling in the trunk and extremities in response to the cool temperature in the examination room. The infant's mother also notices the mottling and asks what it is. What should the nurse tell the mother that this mottling is called?

A) Carotenemia
B) Acrocyanosis
C) Café au lait
D) Cutis marmorata

Persistent or pronounced cutis marmorata occurs with infants born with Down syndrome or those born prematurely and is a transient mottling in the trunk and extremities in response to cool room temperatures. Carotenemia produces a yellow-orange color in light-skinned persons. Acrocyanosis is a bluish color around the lips, hands and fingernails, and feet and toenails. A café au lait spot is a large round or oval patch of light-brown pigmentation.
