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: 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.

Choice A Reason: Episodes of hypoglycemia and hyperglycemia. This is because episodes of hypoglycemia and hyperglycemia are common complications of diabetes during pregnancy, which can affect both the mother and the fetus. Hypoglycemia is a condition where the blood glucose level drops below the normal range, which can cause symptoms such as sweating, trembling, hunger, confusion, or loss of consciousness. Hyperglycemia is a condition where the blood glucose level rises above the normal range, which can cause symptoms such as thirst, polyuria, fatigue, blurred vision, or ketoacidosis. Diabetes during pregnancy requires careful monitoring and management of blood glucose levels to prevent adverse outcomes such as fetal macrosomia, congenital anomalies, stillbirth, or neonatal hypoglycemia.

Choice B Reason: Postpartum hemorrhage. This is an incorrect answer that refers to a different complication that may occur after delivery, not during pregnancy. Postpartum hemorrhage is excessive bleeding from the uterus or genital tract after delivery, which can cause hypovolemic shock, anemia, or death. Postpartum hemorrhage can be caused by uterine atony, retained placenta, lacerations, or coagulation disorders.

Choice C Reason: Cerebrovascular accident (CVA). This is an incorrect answer that indicates a rare and severe complication that may occur during or after pregnancy, not specifically related to diabetes. CVA is also known as stroke, which is an interruption of blood flow to the brain due to ischemia or hemorrhage, which can cause neurological deficits or death. CVA can be caused by hypertension, preeclampsia-eclampsia, thrombophilia, or vascular malformations.

Choice D Reason: Acute vasospasm. This is an incorrect answer that suggests a different condition that may occur during pregnancy, not associated with diabetes. Acute vasospasm is also known as Raynaud's phenomenon, which is a disorder of blood vessels that causes them to narrow and reduce blood flow to the extremities in response to cold or stress, which can cause pain, numbness, or color changes. Acute vasospasm can be triggered by smoking, medications, or autoimmune diseases.
