Before applying a cord clamp, the nurse assesses the umbilical cord for vessels. The nurse expects to find: Select one:
Two arteries, one vein.
Two veins, one artery.
Two veins, two arteries.
One artery, one vein.
The Correct Answer is A
Choice A Reason: Two arteries, one vein. This is because two arteries and one vein are the normal components of the umbilical cord, which is a structure that connects the fetus to the placenta and provides blood circulation between them. The umbilical cord carries oxygenated blood from the placenta to the fetus through the umbilical vein, and deoxygenated blood from the fetus to the placenta through the umbilical arteries.
Choice B Reason: Two veins, one artery. This is an incorrect answer that indicates an abnormal anatomy of the umbilical cord, which is known as single umbilical artery (SUA). SUA is a condition where there is only one umbilical artery instead of two, which can reduce blood flow and oxygen delivery to the fetus. SUA can be associated with congenital anomalies or growth restriction in some cases.
Choice C Reason: Two veins, two arteries. This is an incorrect answer that indicates an abnormal anatomy of the umbilical cord, which is known as double umbilical vein (DUV). DUV is a condition where there are two umbilical veins instead of one, which can increase blood flow and oxygen delivery to the fetus. DUV can be associated with fetal overgrowth or polycythemia in some cases.
Choice D Reason: One artery, one vein. This is an incorrect answer that indicates an abnormal anatomy of the umbilical cord, which is also known as single umbilical artery (SUA). SUA is a condition where there is only one umbilical artery instead of two, which can reduce blood flow and oxygen delivery to the fetus. SUA can be associated with congenital anomalies or growth restriction in some cases.

Correct Answer is B
Explanation
Choice A Reason: "You would have seen more symptoms if you had been looking more closely at your baby." This is an inappropriate response that blames the parents for missing the signs of sepsis and does not explain the Reason for the subtle symptoms.
Choice B Reason: "A newborn's immune system isn't mature, so symptoms are subtle and can be hard to recognize." This is an appropriate response that educates the parents about the immunological basis of sepsis in newborns and reassures them that they are not at fault for not noticing the symptoms.
Choice C Reason: "A high fever will always be present in sick newborns, including your baby." This is an incorrect response that contradicts the fact that newborns may not develop fever in response to infection due to their immature immune systems.
Choice D Reason: "A mother's immunity usually protects the infant from illness, but not in this case." This is an inaccurate response that implies that the mother failed to provide adequate immunity to her baby and does not address the question of why the baby did not seem very ill.
Correct Answer is A
Explanation
Choice A Reason: Macrosomic fetus is a fetus that weighs more than 4000 grams or 8 pounds 13 ounces at birth. It is not a common complication of teenage pregnancy, but rather of maternal diabetes, obesity, or a history of large babies.
Choice B Reason: Preeclampsia is a condition characterized by high blood pressure and proteinuria in pregnancy. It can cause serious complications for both the mother and the baby, such as seizures, organ damage, growth restriction, and placental abruption. Teenage pregnancy is a risk factor for preeclampsia, especially if the mother is younger than 15 years old.
Choice C Reason: Inadequate nutritional status of mother is a condition where the mother does not consume enough calories, protein, vitamins, minerals, or fluids during pregnancy. It can affect the growth and development of the baby and increase the risk of low birth weight, preterm birth, and birth defects. Teenage pregnancy is a risk factor for inadequate nutritional status of mother, as teenagers may have poor dietary habits, eating disorders, or limited access to food.
Choice D Reason: Cephalopelvic disproportion is a condition where the size or shape of the baby's head or body is too large to fit through the mother's pelvis. It can prevent normal vaginal delivery and require cesarean section. Teenage pregnancy is a risk factor for cephalopelvic disproportion, as teenagers may have smaller or immature pelvises that are not fully developed.
