During a physical assessment of a newborn, the nurse observes bluish markings across the newborn's lower back. The nurse interprets this finding as:
Select one:

Milia.

Dermal melanosis.

Stork bites.

Birth trauma.

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is B

Explanation

Choice A Reason: Physiologic anemia due to maternal increased plasma volume. This is an incorrect answer that refers to a diﬀerent condition that aﬀects hemoglobin levels, not blood pressure. Physiologic anemia is a condition where the maternal plasma volume increases more than the red blood cell mass during pregnancy, which dilutes the hemoglobin concentration and lowers the hematocrit value. Physiologic anemia does not cause significant symptoms or complications in pregnant women, as it is an adaptive mechanism that enhances oxygen delivery and prevents ﬂuid overload.

Choice B Reason: Pressure of the gravid uterus on the maternal inferior vena cava and aorta. This is because this statement explains the cause of supine hypotensive syndrome, which is a condition where lying ﬂat on the back causes compression of the major blood vessels by the gravid uterus, which reduces venous return and cardiac output, which lowers blood pressure and perfusion to vital organs. Supine hypotensive syndrome can cause symptoms such as dizziness, lightheadedness, nausea, pallor, or syncope in pregnant women, especially in the third trimester.

Choice C Reason: Pressure of the presenting fetal part on the maternal diaphragm. This is an incorrect answer that indicates a diﬀerent condition that aﬀects respiratory function, not blood pressure. Pressure of the presenting fetal part on the maternal diaphragm is a result of cephalic engagement or lightening, which occurs when the fetal head descends into the pelvis and occupies more space in the abdominal cavity. Pressure of the presenting fetal part on the maternal diaphragm can cause symptoms such as dyspnea, heartburn, or rib pain in pregnant women.

Choice D Reason: A 50% increase in maternal blood volume during pregnancy. This is an incorrect answer that describes a normal physiological change that occurs during pregnancy, not a cause of supine hypotensive syndrome. A 50% increase in maternal blood volume during pregnancy is due to increased production of plasma and red blood cells, which helps meet the increased oxygen and nutrient demands of the fetus and placenta, and prepares the mother for blood loss during delivery. A 50% increase in maternal blood volume during pregnancy does not cause hypotension or dizziness in pregnant women.

A. Manifestations of uteroplacental insufficiency. B. Manifestations of prolapsed cord. C. Manifestations of anaphylactoid syndrome of pregnancy. D. Manifestations of an acute asthmatic episode.

Correct Answer is C

Explanation

Choice A Reason: Manifestations of uteroplacental insufficiency. This is an incorrect answer that describes a diﬀerent condition that aﬀects the fetus, not the mother. Uteroplacental insufficiency is a condition where the placenta fails to deliver adequate oxygen and nutrients to the fetus, which can result in fetal growth restriction, distress, or demise. Uteroplacental insufficiency does not cause shortness of breath, hypoxia, or cyanosis in the mother.

Choice B Reason: Manifestations of prolapsed cord. This is an incorrect answer that refers to another condition that aﬀects the fetus, not the mother. Prolapsed cord is a condition where the umbilical cord slips through the cervix before the baby and becomes compressed by the fetal head, which can reduce oxygen ﬂow to the fetus. Prolapsed cord does not cause shortness of breath, hypoxia, or cyanosis in the mother.

Choice C Reason: Manifestations of anaphylactoid syndrome of pregnancy. This is because anaphylactoid syndrome of pregnancy, also known as amniotic ﬂuid embolism, is a rare and fatal condition where amniotic ﬂuid enters into the maternal bloodstream and causes an allergic reaction, which can lead to respiratory failure, cardiac arrest, coagulopathy, and coma. Anaphylactoid syndrome of pregnancy can occur during or after labor and delivery, especially in cases of NSVD, multiparity, advanced maternal age, or placental abruption.

Choice D Reason: Manifestations of an acute asthmatic episode. This is an incorrect answer that assumes that the mother has a history of asthma or an allergic trigger. Asthma is a chronic inﬂammatory disorder of the airways that causes wheezing, coughing, chest tightness, and dyspnea. Asthma can be exacerbated by pregnancy or labor, but it is not a common cause of sudden onset respiratory distress in the postpartum period.
