Which of the following findings would be most concerning to the nurse caring for a newborn?

A) It could make respiratory distress syndrome worse:
The most critical reason to protect a preterm infant from cold stress is that hypothermia can exacerbate respiratory distress syndrome (RDS). Cold stress leads to an increased oxygen demand, which can worsen the infant’s already compromised respiratory function. In preterm infants, the immature lungs and underdeveloped surfactant production contribute to RDS, and hypothermia worsens the situation by increasing metabolic demands and impairing pulmonary function. Maintaining a stable body temperature is crucial for minimizing respiratory complications.

B) Shivering to produce heat may use up too many calories:
While it is true that preterm infants may not have the metabolic reserves to generate heat via shivering (as they lack significant brown fat), the primary concern is not shivering. Preterm infants generally do not shiver, and cold stress does not trigger this response. Instead, their body tries to conserve heat through vasoconstriction and increased metabolism, which can lead to hypoxia and worsening respiratory distress.

C) A low temperature may make the infant less able to digest nutrients:
Cold stress can affect a preterm infant’s gastrointestinal function by reducing blood flow to the digestive organs, which can impair nutrient absorption and digestion. However, the most immediate and serious consequence of cold stress is the increased metabolic demand and worsening of respiratory distress, rather than a direct impact on digestion. Protecting the infant from hypothermia helps prevent these secondary complications.

D) Cold decreases circulation to the extremities:
While cold stress can indeed lead to vasoconstriction and decreased circulation to the extremities, this is not the most significant concern. The primary issue with cold stress in preterm infants is the overall increase in metabolic demands, oxygen consumption, and exacerbation of respiratory problems, which can lead to more severe respiratory distress syndrome. The loss of peripheral circulation is a secondary concern.

A) Have the client void, then reassess the fundus:
A fundus that is firm but shifted to the right of the midline is a common sign of bladder distention. After childbirth, the bladder may fill with urine, which can displace the uterus and cause it to deviate from the midline, typically to the right. The first step in managing this situation is to have the client void to relieve the bladder distention, which often resolves the uterine shift. Once the bladder is empty, the nurse should reassess the fundus to see if the position returns to midline and remains firm. This is a non-invasive and effective initial intervention.

B) Encourage the client to ambulate:
Encouraging the client to ambulate could be beneficial for overall recovery, but it is not the priority action in this case. The issue at hand is a shifted fundus likely due to bladder distention, which should be addressed by encouraging the client to void first. Ambulation can be considered later when the immediate concern of bladder distention is managed.

C) Notify the healthcare provider:
While notifying the healthcare provider may be necessary if the issue persists after voiding or if there are other signs of complications, it is not the first step. The nurse should first attempt to resolve the issue through bladder emptying, as this is the most common cause of the shift in the fundus. If the problem persists after this, then further steps, including notifying the healthcare provider, would be appropriate.

D) Obtain an order for oxytocin:
Oxytocin is typically administered to help with uterine contraction and involution. However, since the fundus is firm and the primary issue appears to be bladder distention, administering oxytocin is not indicated at this time. The priority is to address the likely cause of the fundus being shifted, which is a full bladder. If the issue persists after voiding, then further intervention such as administering oxytocin may be considered.
