An African American woman noticed some bruises on her newborn girl's buttocks.
She asks the nurse who spanked her daughter.
The nurse explains that these marks are called:
Mongolian spots.
Lanugo.
Nevus flammeus.
Vascular nevus.
The Correct Answer is A
Choice A rationale
Mongolian spots are benign, flat bluish or bluish-gray birthmarks that commonly appear on the buttocks, lower back, or thighs of newborns, particularly those with darker skin tones, including African Americans, Asians, and Hispanics. They are caused by the entrapment of melanocytes (pigment-producing cells) deep within the dermis during fetal development. These spots typically fade spontaneously within a few years and are not indicative of any underlying medical condition or trauma.
Choice B rationale
Lanugo is fine, downy hair that covers the body of some newborns, especially preterm infants. It is usually shed within the last few weeks of gestation or shortly after birth and is unrelated to bruising or pigmented spots on the buttocks.
Choice C rationale
Nevus flammeus, also known as a port-wine stain, is a vascular malformation of the skin that appears as a flat, pink, red, or purple birthmark. It is caused by dilated capillaries and does not typically occur as bluish spots on the buttocks. Port-wine stains are usually permanent and may darken with age.
Choice D rationale
Vascular nevus, also known as a strawberry hemangioma, is a raised, red, bumpy birthmark composed of extra blood vessels. While it is a type of birthmark, it does not present as flat, bluish spots on the buttocks. Hemangiomas typically grow rapidly in the first few months of life and then gradually shrink over several years.

Correct Answer is []
Explanation
Rationale for Correct Condition
Subinvolution refers to delayed uterine involution, often due to retained placental fragments or infection. The boggy uterus, excessive lochia, and passage of clots are hallmark signs. The history of postpartum hemorrhage increases risk, and fundal tenderness suggests uterine atony rather than infection or hematoma formation.
Rationale for Correct Actions
Oxytocin enhances uterine contractions to reduce bleeding and facilitate involution by increasing myometrial tone. Methylergonovine is a potent uterotonic that further supports contraction, decreasing hemorrhage risk, but must be used cautiously in hypertensive patients.
Rationale for Correct Parameters
Saturated perineal pads track blood loss severity, guiding interventions for ongoing hemorrhage. Excessive bleeding may require further medical management. Hemoglobin and hematocrit assess for anemia due to blood loss, guiding transfusion decisions if needed.
Rationale for Incorrect Conditions
Postpartum preeclampsia presents with hypertension and proteinuria, not uterine atony. Perineal hematoma manifests as localized swelling with severe perineal pain, which is absent here. Thrombophlebitis involves unilateral extremity swelling and pain, not fundal tenderness or abnormal lochia.
Rationale for Incorrect Actions
Ice packs to the perineum manage hematomas, not uterine atony. Anticoagulants are used for thromboembolic prevention, not postpartum bleeding. Quiet environment is relevant for preeclampsia, not uterine subinvolution.
Rationale for Incorrect Parameters
Seizures are relevant to preeclampsia, not uterine subinvolution. Calf circumference is monitored for thrombophlebitis, which is absent here. Rectal pain is not an expected indicator of uterine involution status.
Correct Answer is B
Explanation
Choice A rationale
Positioning the newborn supine on a radiant warmer is appropriate for maintaining thermoregulation. However, applying only a sterile gauze dressing to a large abdominal wall defect that is not covered by a membrane does not adequately protect the exposed organs from contamination, drying, or injury. This increases the risk of infection and fluid loss.
Choice B rationale
Placing the newborn into a sterile bowel bag up to the axilla is the recommended immediate action for an abdominal wall defect such as gastroschisis (protrusion without a membrane). The sterile bag helps to maintain a moist environment, prevent heat and fluid loss, and protect the exposed organs from trauma and contamination until surgical repair can be performed.
Choice C rationale
While breastfeeding promotes bonding and provides essential nutrients, it is not the priority action for a newborn with a large, uncovered abdominal wall defect immediately after birth. The immediate focus should be on protecting the exposed organs and stabilizing the newborn. Breastfeeding can be initiated once the newborn is stable and the abdominal defect is appropriately managed.
Choice D rationale
Providing intermittent suction via an orogastric tube may be necessary later to decompress the gastrointestinal system, but it is not the immediate priority for a newborn with a large, uncovered abdominal wall defect. The initial action should focus on protecting the exposed organs.
