A nursing student is helping the nursery nurses with morning vital signs. A baby born 10 hours ago via cesarean section is found to have moist lung sounds. What is the best interpretation of these data?
If this baby was born vaginally, it could indicate a pneumothorax.
The neonate must have aspirated surfactant.
The lungs of a baby delivered by cesarean section may sound moist for 24 hours after birth.
The nurse should notify the pediatrician stat for this emergency situation.
The Correct Answer is C
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.

Correct Answer is C
Explanation
Choice A reason:
While hypoglycemia (glucose <45 mg/dL) is concerning,58 mg/dLis within acceptable ranges for many institutions, especially in asymptomatic newborns. Monitoring is required, but it is less urgent than respiratory distress.
Choice B reason:
Respiratory rate of 78 breaths per minute is also within the normal range for a newborn, which typically ranges from 30 to 60 breaths per minute. Though respiratory rate is essential to assess, it does not take priority over other critical issues.
Choice C reason:
Newborns typically have a normal respiratory rate of30-60 breaths/minute. A rate of78indicatessignificant tachypnea, which could signal respiratory distress (e.g., transient tachypnea of the newborn, infection, or respiratory distress syndrome). Rapid breathing can lead to fatigue, hypoxia, or respiratory failure if not promptly addressed.
Choice D reason:
A glucose reading of 58 mg/dL is concerning in a newborn. Hypoglycemia (low blood glucose) can lead to serious complications if not promptly addressed. Newborns are particularly susceptible to hypoglycemia, and it requires immediate assessment and intervention.
Correct Answer is C
Explanation
Choice A reason:
Rupture of the membranes is not a reliable sign of true labor, as it can occur before or during labor, or be artificially induced by the provider. • Choice B reason:
Patterns of contractions can vary depending on the stage and phase of labor, and can also be influenced by factors such as hydration, activity, and medication. Contractions alone do not indicate true labor unless they are accompanied by cervical changes. • Choice C reason:
Changes in the cervix, such as effacement (thinning) and dilation (opening), are the most accurate indication of true labor. Cervical changes are caused by the pressure of the presenting part and the force of the contractions. The nurse should assess the cervix periodically to determine the progress of labor. • Choice D reason:
The station of the presenting part refers to the relationship of the fetal head to the maternal ischial spines, which are bony landmarks in the pelvis. The station can range from -5 (high) to +5 (low), with 0 being at the level of the ischial spines. Station does not indicate true labor, as it can vary depending on the parity, pelvic shape, and fetal position of the client.
