A nurse in labor and delivery is caring for a client. Following delivery of the placenta, the nurse examines the umbilical cord. Which of the following vessels should the nurse expect to observe in the umbilical cord?

A. Frank breech position

A. In a frank breech presentation, the baby's buttocks are the presenting part. When the nurse locates fetal heart tones above the client's umbilicus at midline during active labor, it is indicative of a breech presentation, and the frank breech position is one possibility.

B. In a cephalic presentation, which is the most common and ideal position for childbirth, the fetal head is the presenting part, and the fetal heart tones would typically be heard below the umbilicus.

C. In a posterior position, the back of the baby's head is against the mother's spine. Fetal heart tones in this position would be typically heard below the umbilicus.

D. In a transverse lie, the baby is positioned horizontally across the uterus. Fetal heart tones may be heard laterally in this position, not necessarily above the umbilicus at midline.

The correct answer is B. Explain to the client this is an expected occurrence.

A. Tell the client to follow up with a dermatologist: While it's always good to encourage clients to seek professional advice if they have concerns, in the context of melasma during pregnancy, it is generally a normal physiological change. A dermatologist may not be needed specifically for this condition unless there are other unusual symptoms.

B. Explain to the client this is an expected occurrence: This is the correct action. It's important for the nurse to reassure the client that blotchy hyperpigmentation on the forehead is a common and expected change during pregnancy. Providing education and support can help alleviate the client's concerns.

C. Instruct the client to increase her intake of vitamin D: Blotchy hyperpigmentation is not typically addressed by increasing vitamin D intake. While adequate nutrition is important during pregnancy, this specific concern is related more to hormonal changes than nutritional deficiencies.

D. Inform the client she might have an allergy to her skin care products: Melasma is primarily related to hormonal changes in pregnancy rather than an allergic reaction to skin care products. While assessing for allergies is essential in certain situations, it may not be the primary concern in this case.
