Which of these is a characteristic of a preterm infant?

Choice A:

Lidocaine gel to the umbilical stump is not a medication that the nurse should expect to administer to a newborn immediately following birth. Lidocaine gel is a topical anesthetic that is used to numb the skin before procedures such as injections or sutures. It is not indicated for the umbilical stump, which does not require any anesthesia.

Choice B:

Hepatitis B immunization is a medication that the nurse should expect to administer to a newborn immediately following birth. Hepatitis B is a viral infection that can cause liver damage and cancer. The immunization protects the newborn from contracting the infection from the mother or other sources. The immunization is given as an intramuscular injection in the anterolateral thigh within 12 hours of birth.

Choice C:

Phytonadione injection is a medication that the nurse should expect to administer to a newborn immediately following birth. Phytonadione is also known as vitamin K, which is essential for blood clotting. Newborns have low levels of vitamin K at birth, which puts them at risk of bleeding disorders such as hemorrhagic disease of the newborn. The injection is given as a single dose of 0.5 to 1 mg in the vastus lateralis muscle within 1 hour of birth.

Choice D:

Antibiotic ophthalmic ointment is a medication that the nurse should expect to administer to a newborn immediately following birth. Antibiotic ophthalmic ointment prevents eye infections caused by bacteria such as gonorrhea or chlamydia, which can be transmitted from the mother during delivery. The ointment is applied to both eyes within 1 hour of birth.

Choice E:

Haemophilus influenzae type b vaccine (Hib) is not a medication that the nurse should expect to administer to a newborn immediately following birth. Hib is a bacterial infection that can cause meningitis, pneumonia, and other serious illnesses. The vaccine protects the newborn from Hib infection, but it is not given at birth. The vaccine is part of the routine immunization schedule and is usually given at 2, 4, and 6 months of age.

Choice A reason:

Maternal/newborn blood group incompatibility is the most common cause of pathologic jaundice, which appears within the first 24 hours of life. This occurs when the mother's antibodies attack the newborn's red blood cells, causing hemolysis and increased bilirubin production. The excess bilirubin causes the yellowish discoloration of the skin and mucous membranes.

Choice B reason:

The absence of vitamin K is not related to jaundice but to hemorrhagic disease of the newborn. Vitamin K is essential for blood clotting and is given to newborns as an injection shortly after birth. Newborns are at risk of vitamin K deficiency because they have low levels of vitamin K in their bodies and breast milk, and their intestinal bacteria are not yet able to synthesize vitamin K.

Choice C reason:

Maternal cocaine abuse can cause many complications for the newborn, such as prematurity, low birth weight, neonatal abstinence syndrome, neurobehavioral problems, and congenital anomalies. However, it is not a direct cause of jaundice in the newborn.

Choice D reason:

Physiologic jaundice is a normal and benign condition that affects about 60% of term newborns. It occurs due to the immature liver's inability to metabolize bilirubin effectively. It usually appears after the first 24 hours of life and peaks around the third or fourth day. It does not require treatment unless the bilirubin level is very high or rising rapidly.
