A diabetic mother born a baby with weight of 3.8 kg . Which of the following finding can be seen in this baby after birth?

Appeared in: NORCET 3 - 2022 (Shift-2)

Explanation

The primary and most immediate complication in an infant of a diabetic mother (IDM) is hypoglycemia.
During pregnancy, the mother's high blood sugar (hyperglycemia) crosses the placenta, causing the fetus to produce excess insulin (hyperinsulinism).
After birth, the maternal glucose supply is suddenly cut off, but the newborn's pancreas continues to secrete high levels of insulin.
This persistent hyperinsulinism causes a rapid drop in the newborn's blood glucose levels, typically within 1-3 hours of life.

Option B: Hyperglycemia is incorrect because the core issue in an IDM is excess insulin, which causes low blood sugar, not high blood sugar.
Option C: While hypocalcemia can occur in IDMs, it is not the most immediate finding. It typically manifests 24 to 72 hours after birth.
Option D: Hypobilirubinemia (low bilirubin) is incorrect. Infants of diabetic mothers are at risk for the opposite condition: hyperbilirubinemia (high bilirubin/jaundice).

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Complications in an infant of a diabetic mother (IDM) as background academic context rather than a clinical decision trigger.
Nurses must perform early and frequent blood glucose monitoring for all infants of diabetic mothers, starting within 30-60 minutes after birth and before each feeding.
Early initiation of feeding (breast or formula) is a key nursing intervention to prevent severe hypoglycemia.
What if? If the mother's diabetes was poorly controlled (high HbA1c), the risk and severity of neonatal hypoglycemia would be even greater, necessitating more vigilant monitoring and a lower threshold for starting IV dextrose.

How to Approach the Question

First, identify the key clinical scenario: an infant born to a diabetic mother.
Recall the core pathophysiology associated with this condition: maternal hyperglycemia leads to fetal hyperinsulinism.
Analyze the transition from intrauterine to extrauterine life. The constant supply of glucose from the mother is cut off at birth.
Consider the effect of the infant's persistent high insulin levels in the absence of the maternal glucose supply. This will lead to a rapid decrease in the infant's blood sugar.
Evaluate the options based on this mechanism. Hypoglycemia is the direct and most immediate consequence.
Rule out the other options: Hyperglycemia is the opposite of what's expected. Hypocalcemia occurs but is typically delayed. Hypobilirubinemia is also incorrect, as these infants are at risk for high bilirubin levels.

Concept Tested & Keywords

Concept Tested: Complications in an infant of a diabetic mother (IDM)
Stem keywords: diabetic mother, baby, after birth
Lead-in keywords: finding can be seen
Clinical cues: The history of maternal diabetes is the key clinical cue, which points towards specific neonatal metabolic derangements.
Negative lead-in flag: false
