Answer:
B. Yellowing of skin and mucous is the correct answer.
Step-by-step explanation: Yellowing the skin and mucous membranes in an infant who is three to four days old is temporary but may require treatment with fluids and photo therapy. Harmless skin markings requiring no intervention include grey, blue or purple spots on the buttocks or sacral area. Vascular markings are also called stork bites, on the neck and transient color changes when side lying.
