A nurse is admitting a term newborn following a cesarean birth. The nurse observes that the newborn's skin is slightly yellow right after birth. This finding indicates the newborn is experiencing a complication related to which of the following?

Physiological jaundice

Maternal cocaine abuse

Maternal/newborn blood group incompatibility

Absence of vitamin K

Answer and Explanation

The Correct Answer is C

Choice A reason: Physiological jaundice is not the correct answer, as it is a normal and benign condition that occurs in about 60% of term newborns, and usually appears after the first 24 hours of life. Physiological jaundice is caused by the breakdown of fetal hemoglobin and the immature liver function, and resolves within a few days.

Choice B reason: Maternal cocaine abuse is not the correct answer, as it is a maternal risk factor that can cause various complications in the newborn, such as low birth weight, prematurity, intrauterine growth restriction, or congenital anomalies. Maternal cocaine abuse does not cause jaundice in the newborn, unless it leads to hepatic or renal dysfunction.

Choice C reason: Maternal/newborn blood group incompatibility is the correct answer, as it is a maternal-fetal condition that can cause hemolytic disease of the newborn, which is a severe form of jaundice that can appear within the first 24 hours of life. Maternal/newborn blood group incompatibility occurs when the mother's blood type is Rh negative and the newborn's blood type is Rh positive, or when the mother's blood type is O and the newborn's blood type is A or B. The maternal antibodies cross the placenta and attack the newborn's red blood cells, causing hemolysis, anemia, and hyperbilirubinemia.

Choice D reason: Absence of vitamin K is not the correct answer, as it is a nutritional deficiency that can cause hemorrhagic disease of the newborn, which is a bleeding disorder that can occur within the first week of life. Absence of vitamin K is due to the lack of intestinal flora and the low vitamin K content in breast milk, and can cause bleeding in the skin, mucous membranes, or internal organs. Absence of vitamin K does not cause jaundice in the newborn, unless it leads to hepatic or biliary dysfunction.

Correct Answer is C

Explanation

Choice A reason: This statement is incorrect, as it describes the direct Coombs test, not the indirect Coombs test. The direct Coombs test is performed on the newborn's blood, and it detects the presence of maternal antibodies that have attached to the newborn's red blood cells. The direct Coombs test can help diagnose hemolytic disease of the newborn, which is a condition where the maternal antibodies destroy the newborn's red blood cells, causing anemia and jaundice.

Choice B reason: This statement is incorrect, as it is not the purpose of the indirect Coombs test, but rather a possible complication of hemolytic disease of the newborn. Kernicterus is a severe form of jaundice that occurs when the bilirubin level in the blood is very high, and it can cause brain damage, deafness, or death. Kernicterus can be prevented by treating the jaundice with phototherapy or exchange transfusion.

Choice C reason: This statement is correct, as it describes the indirect Coombs test, which is performed on the mother's blood, and it detects the presence of Rh-positive antibodies that have formed in response to the exposure to the Rh-positive blood of the newborn. The indirect Coombs test can help identify the risk of hemolytic disease of the newborn, and guide the administration of Rh immunoglobulin, which is a medication that prevents the formation of Rh-positive antibodies.

Choice D reason: This statement is incorrect, as it is not possible for the newborn to have Rh-negative antibodies, since the newborn has Rh-positive blood. Rh-negative antibodies are produced by Rh-negative individuals who have been exposed to Rh-positive blood, such as Rh-negative mothers who have Rh-positive newborns. Rh-negative antibodies can cross the placenta and attack the Rh-positive red blood cells of the newborn, causing hemolytic disease of the newborn.

A. Painless red vaginal bleeding B. Intermittent abdominal pain following passage of bloody mucus C. Increasing abdominal pain with a nonrelaxed uterus D. Abdominal pain with scant red vaginal bleeding

Correct Answer is A

Explanation

Choice A reason: Painless red vaginal bleeding is the most characteristic finding of placenta previa, which is a condition where the placenta covers the cervical opening and can cause bleeding in the third trimester. Painless red vaginal bleeding occurs because the placenta is detached from the lower uterine segment as the cervix dilates or effaces, and the blood vessels are torn. The bleeding can be mild or severe, and it can recur or persist until delivery.

Choice B reason: Intermittent abdominal pain following passage of bloody mucus is not a finding that supports placenta previa, but rather a finding that suggests normal labor or preterm labor. Intermittent abdominal pain is caused by uterine contractions, which can be regular or irregular, and can increase in frequency, duration, and intensity. Bloody mucus is the mucus plug that is expelled from the cervix as it dilates or effaces, and it can be tinged with blood or streaked with blood.

Choice C reason: Increasing abdominal pain with a nonrelaxed uterus is not a finding that supports placenta previa, but rather a finding that indicates abruptio placentae, which is a premature separation of the placenta from the uterine wall. Increasing abdominal pain is caused by the bleeding and the hematoma formation behind the placenta, which can compress the uterine muscle and the nerve endings. Nonrelaxed uterus is a sign of uterine hypertonicity, which can reduce the blood flow and the oxygen delivery to the fetus.

Choice D reason: Abdominal pain with scant red vaginal bleeding is not a finding that supports placenta previa, but rather a finding that suggests ectopic pregnancy, which is a condition where the fertilized ovum implants outside the uterine cavity, usually in the fallopian tube. Abdominal pain is caused by the rupture of the tube and the bleeding into the peritoneal cavity, which can irritate the diaphragm and the abdominal wall. Scant red vaginal bleeding is a sign of implantation bleeding, which can occur when the fertilized ovum attaches to the tube wall.
