A nurse is reviewing laboratory results of a newborn who is 4 hr old. Which of the following findings should the nurse report to the provider?
Bilirubin 9 mg/dL
Hemoglobin 15 g/dL
Platelets 175.0000/mm3
Hematocrit 45%
The Correct Answer is A
Choice A Reason:
Bilirubin 9 mg/dL is correct. A bilirubin level of 9 mg/dL in a newborn, especially at 4 hours old, is elevated and needs prompt attention. High bilirubin levels in newborns can be indicative of jaundice, and severe jaundice may lead to complications such as kernicterus. Monitoring and managing bilirubin levels are crucial to prevent potential neurologic damage.
Choice B Reason:
Hemoglobin 15 g/dL is incorrect. This hemoglobin level is within the normal range for a newborn. It's important to note that newborns often have higher hemoglobin levels shortly after birth, and this value is consistent with normal physiological ranges.
Choice C Reason:
Platelets 175,000/mm³ is incorrect. A platelet count of 175,000/mm³ is within the normal range for a newborn. There is no immediate concern based on this platelet count.
Choice D Reason:
Hematocrit 45% is incorrect. A hematocrit level of 45% is within the normal range for a newborn. Like hemoglobin, hematocrit levels can be higher in newborns shortly after birth, and this value falls within the expected range.

Correct Answer is A
Explanation
The correct answer is A. Two arteries and one vein.
A. Two arteries and one vein is the typical composition of the umbilical cord vessels. The umbilical arteries carry deoxygenated blood and waste products away from the fetus, while the umbilical vein carries oxygenated blood and nutrients to the fetus.
B. Two veins and one artery is not the usual configuration of the umbilical cord vessels. The presence of two veins is atypical.
C. One artery and one vein is an abnormal finding and may be associated with certain congenital anomalies or fetal abnormalities. This configuration is not the norm.
D. Two arteries and two veins is not a standard or physiological composition of the umbilical cord. The typical configuration is two arteries and one vein.
Correct Answer is A
Explanation
The correct answer is A. Variable decelerations are due to umbilical cord compression.
A. Variable decelerations are often associated with umbilical cord compression. This compression can occur when the umbilical cord is briefly compressed or squeezed, leading to transient decreases in fetal heart rate.
B. Variable decelerations are not typically a result of the administration of IV narcotic analgesics. They are more commonly associated with cord compression or other factors affecting fetal oxygenation.
C. Variable decelerations are not generally caused by uteroplacental insufficiency. Uteroplacental insufficiency is more commonly associated with late decelerations.
D. Variable decelerations are not primarily related to fetal head compression. While head compression can cause certain types of decelerations, variable decelerations are specifically associated with umbilical cord compression.
