During a vaginal delivery, the first thing a nurse must ensure when the head comes out is that the midwife or doctor checks that

The correct answer is: a. Hyperbilirubinemia.

Choice A: Hyperbilirubinemia

Reason: Hyperbilirubinemia in newborns is often caused by the increased breakdown of red blood cells, which have a shorter lifespan in neonates. This breakdown produces bilirubin, a yellow pigment that can accumulate in the blood, leading to jaundice. The liver of a newborn is not fully mature and may not be able to process and excrete bilirubin efficiently, resulting in hyperbilirubinemia.

Choice B: Respiratory Distress Syndrome

Reason: Respiratory Distress Syndrome (RDS) is primarily caused by a deficiency of surfactant in the lungs, which is more common in premature infants. It is not directly related to the lifespan of red blood cells. Symptoms include rapid, shallow breathing and a bluish color due to lack of oxygen.

Choice C: Polycythemia

Reason: Polycythemia is characterized by an abnormally high concentration of red blood cells. It is often due to factors like delayed cord clamping or maternal diabetes, rather than the decreased lifespan of red blood cells. Polycythemia can lead to increased blood viscosity and complications such as sluggish blood flow.

Choice D: Transient Tachypnea

Reason: Transient Tachypnea of the Newborn (TTN) is a respiratory condition caused by delayed clearance of fetal lung fluid. It typically resolves within a few days and is not related to the lifespan of red blood cells. Symptoms include rapid breathing and grunting.

Choice A reason:

The cord is still pulsating. This is not the first thing a nurse must ensure when the head comes out because the cord normally pulsates until the placenta is delivered. The pulsation indicates that the cord is still functioning and transferring blood and oxygen between the baby and the placenta. However, this does not mean that the cord is free from any complications that could endanger the baby's life, such as a nuchal cord (a cord wrapped around the neck) or a prolapsed cord (a cord that slips out before the baby). • Choice B reason:

The cord is intact. This is not the first thing a nurse must ensure when the head comes out because the cord is usually intact until it is clamped and cut after the delivery of the baby. The cord can be ruptured by excessive traction or twisting, which can cause bleeding and shock in the baby. However, this is a rare occurrence and does not pose an immediate threat to the baby's life as long as the cord is still attached to the placenta. • Choice C reason:

No part of the cord is encircling the baby's neck. This is the correct answer because a nuchal cord can cause compression of the cord and reduce blood flow and oxygen to the baby, leading to fetal distress, hypoxia, and brain damage. A nuchal cord occurs in about 10 to 30 percent of deliveries and can be detected by feeling for a loop of cord around the neck as the head emerges. If a nuchal cord is present, it should be gently slipped over the head or clamped and cut before delivery of the shoulders. • Choice D reason:

The cord is still attached to the placenta. This is not the first thing a nurse must ensure when the head comes out because the cord is always attached to the placenta until it separates from the uterine wall and is expelled after the delivery of the baby. The placenta provides nourishment and oxygen to the baby through the cord. However, this does not mean that the cord is free from any complications that could endanger the baby's life, such as a nuchal cord or a prolapsed cord.
