The student nurse learns that the hormone necessary for milk production is

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.

Choice A reason:

Obtaining blood glucose by heel stick is the appropriate action for a newborn who exhibits signs of diaphoresis, jitteriness, and lethargy. These signs are suggestive of hypoglycemia, which is a common and potentially serious condition in newborns. Hypoglycemia can result from various causes, such as maternal diabetes, prematurity, intrauterine growth restriction, or perinatal stress. A heel stick is a simple and quick method to obtain blood samples from newborns for glucose testing.

Choice B reason:

Initiating phototherapy is not the appropriate action for a newborn who exhibits signs of diaphoresis, jitteriness, and lethargy. Phototherapy is used to treat hyperbilirubinemia, which is a condition characterized by high levels of bilirubin in the blood. Hyperbilirubinemia can cause jaundice, which is a yellowish discoloration of the skin and eyes. Jaundice does not typically cause diaphoresis, jitteriness, or lethargy in newborns.

Choice C reason:

Monitoring the newborn's blood pressure is not the appropriate action for a newborn who exhibits signs of diaphoresis, jitteriness, and lethargy. Blood pressure measurement is not routinely performed in healthy newborns. Blood pressure may be indicated in newborns who have signs of cardiovascular compromise, such as cyanosis, tachycardia, or poor perfusion. Diaphoresis, jitteriness, and lethargy are not specific signs of cardiovascular compromise in newborns.

Choice D reason:

Placing the newborn in a radiant warmer is not the appropriate action for a newborn who exhibits signs of diaphoresis, jitteriness, and lethargy. A radiant warmer is a device that provides heat to maintain the newborn's body temperature. A radiant warmer may be used for newborns who are at risk of hypothermia, such as those who are premature, have low birth weight, or have cold stress. Diaphoresis, jitteriness, and lethargy are not specific signs of hypothermia in newborns.
