After the delivery of the placenta, a nurse in labor and delivery examines the umbilical cord.
Which of the following vessels should the nurse expect to observe in the umbilical cord?

Choice B rationale

When a couple is found to be carriers of an autosomal-recessive disorder, one of the actions the nurse can take is to discuss options with the couple, including amniocentesis to determine if their fetus is affected. This procedure can provide definitive information about the genetic status of the fetus, allowing the couple to make informed decisions about the pregnancy.

Choice A rationale

Strabismus, or crossed eyes, is a condition that typically requires treatment and is not normal in newborns. It involves a lack of coordination between the muscles that control eye movement, causing the eyes to point in different directions.

Choice B rationale

While it’s important to report concerns to the primary care provider, this statement does not directly address the mother’s concern about her newborn’s crossed eyes.

Choice C rationale

Taking the baby to the nursery for further examination may be necessary in some cases, but it does not provide the mother with immediate reassurance or information about her newborn’s condition.

Choice D rationale

Newborns often lack the muscle control necessary to regulate eye movement, which can cause their eyes to cross. This is a normal part of development and typically resolves on its own within the first few months of life.
