Explanation

Infants of diabetic mothers (IDMs) experience a sudden cutoff of the maternal glucose supply at birth.
However, their own pancreas continues to produce high levels of insulin (hyperinsulinemia) in response to the previous in-utero environment.
This persistent hyperinsulinemia leads to rapid glucose consumption and subsequent hypoglycemia (low blood sugar), not hyperglycemia (high blood sugar).
Therefore, hyperglycemia is the condition that is NOT a typical immediate complication for these infants.

Option A: Hypoglycemia is the most common metabolic complication in infants of diabetic mothers due to persistent fetal hyperinsulinemia after birth.
Option B: Hypomagnesemia is a known complication in infants of diabetic mothers, often occurring alongside hypocalcemia.
Option D: Hypocalcemia is a frequent finding in infants of diabetic mothers, typically appearing within the first 24-72 hours of life due to a delayed parathyroid hormone response.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Neonatal complications of maternal diabetes as background academic context rather than a clinical decision trigger.
Nurses must perform routine blood glucose monitoring for all infants of diabetic mothers, typically starting within the first hour of life and continuing for at least 24-48 hours.
Early and frequent feeding (breast milk or formula) is a key nursing intervention to prevent hypoglycemia in these at-risk newborns.
What if? If the mother had well-controlled diabetes with normal blood glucose levels throughout pregnancy, the risk of neonatal hypoglycemia would be significantly lower, but the infant would still require routine monitoring as a precaution.

How to Approach the Question

First, identify the core concept of the question, which is the metabolic effects of maternal diabetes on a newborn.
Recognize that this is an 'except' question, meaning you need to find the option that is FALSE or not a typical complication.
Recall the key pathophysiological process: maternal hyperglycemia causes fetal hyperinsulinemia.
Think through the transition at birth: the maternal glucose supply is cut, but the baby's high insulin level persists.
Analyze the effect of high insulin without a high glucose supply: it will cause blood sugar to drop. This leads to hypoglycemia.
Evaluate each option based on this understanding. Hypoglycemia, hypocalcemia, and hypomagnesemia are all known complications. Hyperglycemia is the opposite of what is expected, making it the correct answer.
