At 22 weeks' gestation, a client is diagnosed with placenta previa. The doctor tells the client that the placenta may move away from the cervix as the pregnancy progresses. This is classified as what type of previa?

Choice A Reason: Partial placenta previa is a condition where the placenta partially covers the cervix. It usually does not resolve and may cause bleeding and complications during labor and delivery.

Choice B Reason: Complete placenta previa is a condition where the placenta completely covers the cervix. It is a serious condition that requires cesarean delivery and may cause life-threatening hemorrhage.

Choice C Reason: Marginal placenta previa is a condition where the edge of the placenta reaches the margin of the cervix. It may also cause bleeding and complications during labor and delivery.

Choice D Reason: Low-lying placenta previa is a condition where the placenta is near the cervix, but not covering it. It may resolve spontaneously as the uterus grows and the placenta moves upward.

Choice A Reason: Milia. This is an incorrect answer that describes a different skin condition. Milia are tiny white or yellow cysts that appear on the nose, chin, or cheeks of newborns. They are caused by the retention of keratin in the sebaceous glands or hair follicles. They usually disappear within a few weeks without treatment.

Choice B Reason: Dermal melanosis. This is a correct answer that explains the finding of bluish markings across the newborn's lower back. Dermal melanosis. This is because dermal melanosis, also known as Mongolian spots, is a common benign skin condition that affects newborns of Asian, African, or Hispanic descent. It is characterized by bluish-gray or brown patches of pigmentation on the lower back, butocks, or extremities. It is caused by the migration of melanocytes from the neural crest to the dermis during embryonic development. It usually fades by 2 to 4 years of age.

Choice C Reason: Stork bites. This is an incorrect answer that refers to another skin condition. Stork bites, also known as salmon patches or nevus simplex, are flat pink or red marks that appear on the forehead, eyelids, nose, upper lip, or nape of the neck of newborns. They are caused by dilated capillaries in the superficial dermis. They usually fade by 18 months of age.

Choice D Reason: Birth trauma. This is an incorrect answer that implies an injury or damage to the newborn's skin or tissues during labor and delivery. Birth trauma can cause bruises, abrasions, lacerations, fractures, or nerve injuries. It is not related to bluish markings on the lower back.
