A nurse is reviewing the laboratory results of a newborn who has hypoglycemia.
The nurse should identify that a normal blood glucose level for a healthy term newborn is between which of the following ranges?
10 and 30 mg/dL
30 and 60 mg/dL
60 and 90 mg/dL
90 and 120 mg/dL.
The Correct Answer is B
A normal blood glucose level for a healthy term newborn is between 30 and 60 mg/dL. This range is lower than that of older children and adults, because newborns are adapting to life outside the womb and their glucose levels rise gradually after birth.
Choice A is wrong because 10 and 30 mg/dL is too low for a newborn and indicates hypoglycemia, which can cause symptoms such as jitteriness, poor feeding, lethargy, and cyanosis.
Choice C is wrong because 60 and 90 mg/dL is too high for a newborn and indicates hyperglycemia, which can cause symptoms such as dehydration, poor feeding, irritability, and seizures.
Choice D is wrong because 90 and 120 mg/dL is also too high for a newborn and indicates hyperglycemia, which can have the same consequences as choice C.

Correct Answer is D
Explanation
Phototherapy is a treatment that uses light to break down bilirubin in the blood and make it easier for the liver to eliminate it.
Phototherapy is effective when:
• The bilirubin levels decrease within 24 hours of treatment.
This means that the bilirubin is being cleared faster than it is being produced.
• The urine output and stool frequency increase during treatment.
This means that the bilirubin is being excreted through the kidneys and intestines.
• The skin color and muscle tone improve after treatment.
This means that the bilirubin is no longer causing jaundice or affecting the nervous system.
Statement A is wrong because it only describes one aspect of phototherapy effectiveness.
Statement B is wrong because it only describes another aspect of phototherapy effectiveness.
Statement C is wrong because it only describes the outcome of phototherapy effectiveness.
Statement D is correct because it includes all three aspects of phototherapy effectiveness.
Correct Answer is C
Explanation
This is a sign of dehydration, which can be caused by phototherapy.Phototherapy increases insensible water loss through the skin and can lead to fluid and electrolyte imbalance in the newborn.The nurse should monitor the newborn’s hydration status, weight, urine output, and serum electrolytes and provide adequate fluid intake.
Choice A is wrong because conjunctivitis is not a common complication of phototherapy.It can be prevented by using eye shields or patches to protect the newborn’s eyes from the light source.
Choice B is wrong because bronze skin discoloration is a rare complication of phototherapy that occurs when the bilirubin level is very high and the skin pigment changes.It is not a priority finding and usually resolves after phototherapy is discontinued.
Choice D is wrong because maculopapular skin rash is a benign side effect of phototherapy that does not require intervention.It usually disappears within a few days after phototherapy is stopped.
