Routine Newborn Medications & Preventive Care
Overview
Routine newborn medications prevent three serious problems before symptoms begin. Vitamin K prevents vitamin K deficiency bleeding. Erythromycin ophthalmic ointment prevents gonococcal eye infection. Hepatitis B immunoprophylaxis prevents perinatal hepatitis B infection. Match each medication to its purpose, timing, route, and maternal hepatitis B surface antigen status.
Vitamin K
Newborns begin life with low vitamin K stores, so they cannot make clotting factors II, VII, IX, and X efficiently. A one-time intramuscular dose prevents vitamin K deficiency bleeding.
Eye Prophylaxis
Erythromycin ophthalmic ointment protects the newborn's eyes from gonococcal ophthalmia neonatorum, which can rapidly damage the cornea and cause blindness.
Hepatitis B
Maternal hepatitis B surface antigen, or HBsAg, status drives newborn protection. Positive status requires both vaccine and hepatitis B immune globulin. Unknown status requires vaccine promptly while the maternal result is resolved.

Patient Teaching
Clinical Pearl
Match the three newborn preventives: vitamin K prevents bleeding, erythromycin protects the eyes from gonorrhea, and an HBsAg-positive mother means hepatitis B vaccine plus HBIG within 12 hours.
