A newborn of a birthing parent with poorly controlled type 1 diabetes mellitus is admitted to the neonatal intensive care unit. The infant was born at 38 weeks gestation via cesarean section due to macrosomia, weighing 4,200 grams (9 lbs 4 oz). The infant's initial blood glucose level is 30 mg/dL, and vital signs are: heart rate 165 bpm, respiratory rate 68 breaths/min with mild retractions, temperature 97.2°F (36.2°C). The infant appears lethargic and has a weak cry. Which nursing intervention is the highest priority for this infant during the first 24 hours after birth?
The nurse is caring for a newborn whose birthing parent has poorly controlled type 1 diabetes mellitus. The infant was born at 38 weeks gestation via cesarean section due to macrosomia, weighing 4,200 grams (9 lbs 4 oz). The infant's initial blood glucose level is 35 mg/dL, and vital signs are: heart rate 165 bpm, respiratory rate 68 breaths/min with mild retractions, temperature 97.2°F (36.2°C). The infant appears jittery and has a weak cry.

Infants of diabetic mothers are at highest risk for hypoglycemia in the first 24-48 hours due to hyperinsulinemia. Monitoring and treating hypoglycemia is the priority to prevent neurological damage.
錯誤選項分析 (Distractor Analysis):
① 預防性給予抗生素:雖然 IDM 感染風險可能略增,但題幹未提供任何感染徵象(如:發燒、白血球異常、母親有明確感染)。在急性低血糖威脅下,這並非最優先事項。
② 監測呼吸窘迫症候群徵象:IDM 因高胰島素會抑制肺泡表面張力素的生成,確實是新生兒呼吸窘迫症候群 (RDS)的高風險群。題中呼吸速率68次/分伴輕微肋間凹陷,需持續觀察,但相較於已確診且數值極低的低血糖,其緊急性仍次之。且38週已近足月,RDS風險較早產兒低。
③ 評估先天性異常與產傷:IDM 先天性異常(如:心臟、神經管缺陷)風險較高,巨嬰也易導致產傷(如:臂神經叢損傷、鎖骨骨折)。這是重要的全面性評估,但屬於「全面性評估」的一部分,而非針對當前急性生命威脅的「優先處置」。
