After teaching a pregnant woman about the hormones produced by the placenta, the nurse determines that the teaching was successful when the woman identifies which hormone produced as being the basis for pregnancy tests?

The correct answer is: c. The lungs of a baby delivered by cesarean section may sound moist for 24 hours after birth.

Choice A reason:

If this baby was born vaginally, it could indicate a pneumothorax.

A pneumothorax occurs when air leaks into the space between the lung and chest wall, causing the lung to collapse. This condition can happen in newborns, especially those with underlying lung issues or those who have undergone mechanical ventilation However, moist lung sounds in a newborn are not typically indicative of a pneumothorax. Pneumothorax is more likely to present with symptoms such as rapid breathing, grunting, and cyanosis.

Choice B reason:

The neonate must have aspirated surfactant.

Surfactant aspiration is not a common cause of moist lung sounds. Surfactant is a substance that helps keep the lungs’ air sacs open and is crucial for proper lung function. Aspiration of surfactant is not a typical diagnosis and would not usually result in moist lung sounds. Instead, surfactant deficiency or dysfunction can lead to respiratory distress syndrome, which presents differently.

Choice C reason:

The lungs of a baby delivered by cesarean section may sound moist for 24 hours after birth.

Babies born via cesarean section often have moist lung sounds because they do not experience the compression of the chest that occurs during vaginal delivery, which helps expel fluid from the lungs. This retained fluid can cause moist lung sounds, which typically resolve within the first 24 hours after birth. This is a normal finding and does not usually indicate a serious problem.

Choice D reason:

The nurse should notify the pediatrician stat for this emergency situation.

While it is always important to monitor newborns closely, moist lung sounds alone in a baby born via cesarean section are not typically an emergency. This finding is usually due to retained fluid in the lungs, which is expected to clear within the first day of life. Immediate notification of the pediatrician is not necessary unless the baby shows other signs of respiratory distress or other concerning symptoms.

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.
