Final answer:
The test results that would require notification of the pediatrician include a glucose level of 34 mg/dL, indicating hypoglycemia; a calcium level of 6 mg/dL, indicating hypocalcemia; and while a total serum bilirubin of 3.1 mg/dL isn't immediately alarming, it should be monitored closely.
Step-by-step explanation:
In evaluating the laboratory test results of a full-term newborn who is 4 hours old, certain values are concerning and would necessitate notifying a pediatrician:
- Glucose 34 mg/dL: A glucose level of 34 mg/dL is low, indicating hypoglycemia. Newborns generally have a lower glucose level than children and adults, but a level below 40 mg/dL is concerning and may require intervention to prevent potential harm.
- Total serum bilirubin 3.1 mg/dL: While a bilirubin level of 3.1 mg/dL is usually not alarming for a 4-hour-old newborn, it should be monitored closely as levels may increase and risk of jaundice or kernicterus arises if the bilirubin value sharply increases over the next days.
- Calcium 6 mg/dL: This is a notably low level as the normal range for serum calcium in newborns is around 7 to 12 mg/dL. Hypocalcemia, or low calcium, can lead to seizures and other serious issues and should be addressed by a pediatrician.
The other values such as hemoglobin 20 g/dL, hematocrit 54%, and white blood cell count 24,000/mm3 may be higher than adult norms but are within expected ranges for newborns immediately following birth. It is important to have a pediatrician interpret these results in the context of each individual newborn's health status.
