In a neonate born at 30 weeks with respiratory distress syndrome, which medication is most appropriate to appear on the baby's drug chart in the first few hours?

• A. Oral Vitamin K
• B. Intravenous Vitamin C
• C. Vitamin D Injection
• D. Iron Supplement

Answer: (A)

Vitamin K prophylaxis right after birth is essential to prevent hemorrhagic disease in newborns. The newborn gut is sterile at birth and cannot reliably produce vitamin K; the liver also needs vitamin K to activate clotting factors II, VII, IX, and X (and proteins C and S). In preterm babies, vitamin K stores are even lower and liver maturity is incomplete, raising the risk of early bleeding in the first hours and days. Giving vitamin K intramuscularly soon after birth provides reliable protection against VKDB, which is why this medication belongs on the drug chart in the first few hours. Other options like vitamin D, vitamin C, or iron are not indicated for immediate bleeding prevention in this time frame, and oral vitamin K can be less reliable than the intramuscular route in the hospital setting.
