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 A
Explanation
Choice A Reason: Episodes of hypoglycemia and hyperglycemia. This is because episodes of hypoglycemia and hyperglycemia are common complications of diabetes during pregnancy, which can affect both the mother and the fetus. Hypoglycemia is a condition where the blood glucose level drops below the normal range, which can cause symptoms such as sweating, trembling, hunger, confusion, or loss of consciousness. Hyperglycemia is a condition where the blood glucose level rises above the normal range, which can cause symptoms such as thirst, polyuria, fatigue, blurred vision, or ketoacidosis. Diabetes during pregnancy requires careful monitoring and management of blood glucose levels to prevent adverse outcomes such as fetal macrosomia, congenital anomalies, stillbirth, or neonatal hypoglycemia.
Choice B Reason: Postpartum hemorrhage. This is an incorrect answer that refers to a different complication that may occur after delivery, not during pregnancy. Postpartum hemorrhage is excessive bleeding from the uterus or genital tract after delivery, which can cause hypovolemic shock, anemia, or death. Postpartum hemorrhage can be caused by uterine atony, retained placenta, lacerations, or coagulation disorders.
Choice C Reason: Cerebrovascular accident (CVA). This is an incorrect answer that indicates a rare and severe complication that may occur during or after pregnancy, not specifically related to diabetes. CVA is also known as stroke, which is an interruption of blood flow to the brain due to ischemia or hemorrhage, which can cause neurological deficits or death. CVA can be caused by hypertension, preeclampsia-eclampsia, thrombophilia, or vascular malformations.
Choice D Reason: Acute vasospasm. This is an incorrect answer that suggests a different condition that may occur during pregnancy, not associated with diabetes. Acute vasospasm is also known as Raynaud's phenomenon, which is a disorder of blood vessels that causes them to narrow and reduce blood flow to the extremities in response to cold or stress, which can cause pain, numbness, or color changes. Acute vasospasm can be triggered by smoking, medications, or autoimmune diseases.
Correct Answer is C
Explanation
Choice A Reason: Macrosomic newborn. This is a correct answer that describes a possible complication of post-term pregnancy. A macrosomic newborn is a newborn that weighs more than 4000 grams or 8 pounds 13 ounces at birth. It can occur in post-term pregnancies due to prolonged exposure to maternal glucose and insulin. It can increase the risk of birth injuries, shoulder dystocia, cesarean delivery, and hypoglycemia.
Choice B Reason: Intrauterine growth restriction (IUGR). This is a correct answer that indicates a potential problem of post-term pregnancy. IUGR is a condition where the fetal growth is slower than expected for gestational age. It can occur in post-term pregnancies due to placental insufficiency, aging, or calcification, which can impair nutrient and oxygen delivery to the fetus. It can increase the risk of fetal distress, hypoxia, acidosis, and stillbirth.
Choice C Reason: Umbilical cord prolapse. This is an incorrect answer that does not reflect a risk of post-term pregnancy, but rather a risk of other factors such as prematurity, low birth weight, breech presentation, multiple gestation, polyhydramnios, or artificial rupture of membranes.
Choice D Reason: Meconium Aspiration Syndrome (MAS). This is a correct answer that denotes a possible complication of post-term pregnancy. MAS occurs when fetal stool (meconium) enters into the lungs before or during birth, causing airway obstruction, inflammation, and infection. MAS usually affects term or post-term infants who experience fetal distress or hypoxia in utero. It can cause respiratory distress syndrome (RDS), persistent pulmonary hypertension (PPHN), or chronic lung disease (CLD).
