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.
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 A
Explanation
Choice A Reason: Docusate sodium (Colace). This is because docusate sodium is a stool softener that can prevent constipation and straining during defecation, which can aggravate or impair the healing of a perineal laceration. A fourth-degree perineal laceration is a severe tear that extends through the skin, muscles, perineal body, and anal sphincter into the rectal mucosa. It can occur during vaginal delivery due to factors such as fetal macrosomia, forceps use, or episiotomy.
Choice B Reason: Bromocriptine (Parlodel). This is an inappropriate medication for a postpartum client with a fourth- degree perineal laceration, as it has no effect on wound healing or pain relief. Bromocriptine is a dopamine agonist that can suppress lactation by inhibiting prolactin secretion. It is used for women who do not wish to breastfeed or who have medical contraindications to breastfeeding.
Choice C Reason: Ferrous sulfate (Feosol). This is an unnecessary medication for a postpartum client with a fourth- degree perineal laceration, unless she has iron deficiency anemia. Ferrous sulfate is an iron supplement that can treat or prevent anemia by increasing hemoglobin production and oxygen-carrying capacity. Anemia can occur in the postpartum period due to blood loss during delivery or poor nutritional intake during pregnancy.
Choice D Reason: Methylergonovine (Methergine). This is an irrelevant medication for a postpartum client with a fourth-degree perineal laceration, as it does not affect wound healing or pain relief. Methylergonovine is an ergot alkaloid that can stimulate uterine contractions and reduce postpartum bleeding. It is used for women who have uterine atony or hemorrhage.
Correct Answer is D
Explanation
Choice A Reason: Vitamin K will increase erythropoiesis. This is an incorrect statement that confuses vitamin K with erythropoietin. Erythropoietin is a hormone that stimulates red blood cell production in the bone marrow. Vitamin K does not affect erythropoiesis.
Choice B Reason: Vitamin K will enhance bilirubin breakdown. This is an incorrect statement that confuses vitamin K with phototherapy. Phototherapy is a treatment that exposes the newborn's skin to light, which converts bilirubin into water-soluble forms that can be excreted by the liver and kidneys. Bilirubin is a yellow pigment that results from the breakdown of red blood cells. High levels of bilirubin can cause jaundice and brain damage in newborns. Vitamin K does not affect bilirubin metabolism.
Choice C Reason: Vitamin K will stop Rh sensitization. This is an incorrect statement that confuses vitamin K with Rh immune globulin. Rh immune globulin is an injection given to Rh-negative mothers who deliver Rh-positive babies, to prevent them from developing antibodies against Rh-positive blood cells in future pregnancies. Rh sensitization is a condition where the mother's immune system atacks the baby's blood cells, causing hemolytic disease of the newborn. Vitamin K does not affect Rh sensitization.
Choice D Reason: Vitamin K will promote blood clotting ability. This is a correct statement that explains the rationale for administering vitamin K as prophylaxis to newborns. Vitamin K is essential for the synthesis of clotting factors in the liver. Newborns have low levels of vitamin K at birth due to poor placental transfer and lack of intestinal bacteria that produce vitamin K. Therefore, they are at risk of bleeding disorders such as hemorrhagic disease of the newborn.
