The student nurse is preparing to assess the fetal heart rate (FHR). She has determined that the fetal back is located toward the client's left side, the small parts toward the right side, and there is a vertex (occiput) presentation. The student nurse should initially begin auscultation of the fetal heart rate in the mother's:

A) Milia:
Milia are tiny white or yellowish cysts that appear on a newborn's face, particularly on the nose, chin, or forehead. They are caused by the accumulation of keratin under the skin. Milia usually disappear within a few weeks of life and are not related to the pinkish marks described in the question.

B) Telangiectatic nevi (stork bites):
This finding is consistent with telangiectatic nevi, also known as stork bites. These are flat, irregular, pinkish-red marks often found on the forehead, eyelids, and nape of the neck. They are caused by dilated capillaries in the skin and are common in newborns. The marks blanch when pressed and are usually harmless, disappearing within the first 1-2 years of life. This is the correct answer based on the description provided in the question.

C) Nevus flammeus (port wine stain):
A port wine stain is a dark red to purple, flat birthmark caused by capillary malformations. Unlike stork bites, a port wine stain does not blanch when pressed and is typically present for life. It usually appears on the face, neck, or arms, and the coloration remains the same over time.

D) Nevus vasculosus (strawberry mark):
A strawberry mark is a raised, red, and bumpy birthmark that results from proliferation of capillaries. These marks typically appear in the first few weeks of life and grow in size before eventually shrinking and disappearing by the age of 5-10 years. Strawberry marks are not flat, pinkish, or blanchable, making this option unlikely in the scenario described.

A) Presence of a two-vessel umbilical cord:
The presence of a two-vessel umbilical cord (instead of the normal three vessels, which includes two arteries and one vein) is a significant finding that requires follow-up. A two-vessel cord can be associated with fetal anomalies, particularly with renal, cardiac, or chromosomal conditions. Therefore, it requires further evaluation to rule out any underlying conditions and ensure proper organ development.

B) Molding of the skull:
Molding of the skull is a normal and expected finding in newborns following a vaginal birth, especially after a long or difficult delivery. It refers to the temporary reshaping of the fetal skull bones as they overlap to pass through the birth canal. This is typically self-correcting and resolves within a few days, so no follow-up is needed for molding.

C) Asymmetry of ears:
Asymmetry of the ears can indicate congenital anomalies, such as craniofacial syndromes or other physical deformities. Although some degree of asymmetry can occur in newborns, especially in the first hours of life, persistent or significant asymmetry should be evaluated further. It may indicate an abnormality that requires follow-up or assessment by a specialist.

D) Tongue extending past the lower lip:
A tongue that extends past the lower lip is a normal finding in newborns, as babies are still developing their oral reflexes and muscle tone. This is not a cause for concern, and no follow-up is required unless other feeding issues arise. It's important to differentiate between normal tongue movements and more serious concerns like tongue-tie (ankyloglossia), but this is not indicative of a problem by itself.

E) Diminished breath sounds on one side:
Diminished breath sounds on one side of the chest can indicate a serious issue, such as a pneumothorax, diaphragmatic hernia, or other respiratory concerns. This finding warrants immediate follow-up, as the newborn could be experiencing a respiratory distress condition that needs urgent intervention and management. This is a significant finding requiring immediate evaluation.
