What causes congenital hip dysplasia?

Choice A reason:

Asymmetrical breathing is not a sign of meconium aspiration syndrome (MAS). It is a sign of diaphragmatic hernia, a condition where the abdominal organs push into the chest cavity and interfere with lung development.

Choice B reason:

Born before 38 weeks gestation is not a sign of MAS. It is a risk factor for respiratory distress syndrome (RDS), a condition where the lungs are not fully developed and lack surfactant, a substance that helps keep the air sacs open.

Choice C reason:

Yellow-green staining on the umbilical cord is a sign of MAS. It indicates that the baby has passed meconium into the amniotic fluid before or during birth and may have inhaled it into the lungs. Meconium is a sticky substance that becomes the baby's first poop. It can block or irritate the airways, damage lung tissue and prevent oxygen exchange.

Choice D reason:

Acrocyanosis is not a sign of MAS. It is a normal finding in newborns where the hands and feet appear bluish due to immature circulation. It usually resolves within 24 to 48 hours after birth.

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.
