A nurse is reinforcing teaching about formula feeding to a group of parents of newborns.

Which of the following statements by one of the parents indicates a need for further teaching?

Choice A rationale: The umbilical cord contains three blood vessels: two arteries and one vein. The two arteries carry deoxygenated blood and waste products from the fetus back to the placenta, while the one vein carries oxygenated blood and nutrients from the placenta to the fetus.
Choice B rationale: This option is incorrect because the umbilical cord in a newborn does not have two veins. It contains two arteries and one vein.
Choice C rationale: This option is incorrect because the umbilical cord in a newborn does not have two veins and one artery. It contains two arteries and one vein.
Choice D Rationale: This option is incorrect because the umbilical cord in a newborn does not have only one artery and one vein. It contains two arteries and one vein.

Choice A rationale; Erythema toxicum is a common rash that appears in many newborns and is not a cause for concern. It presents as small red bumps or pustules on the skin and usually resolves on its own without treatment.
Choice B rationale: A Mongolian spot is a birthmark that appears as a bluish-gray or bruise-like patch on the baby's skin, often on the back or buttocks. It is a benign condition and does not require any medical intervention.
Choice C rationale: Telangiectatic nevi, also known as "stork bites" or "angel kisses," are flat, pink, or red birthmarks that are common in newborns. They are usually found on the eyelids, forehead, and back of the neck. These birthmarks are harmless and typically fade over time without treatment.
Choice D rationale: Jaundice is a common condition in newborns and is caused by elevated levels of bilirubin in the blood. In most cases, mild jaundice is not harmful and resolves on its own. However, if the baby's skin and sclera (white part of the eyes) show significant yellowing, it may indicate a higher level of bilirubin, which can lead to complications if not properly managed. Therefore, the nurse should report this finding to the provider for further evaluation and appropriate treatment if necessary.
