Part of the health assessment of a newborn includes observation of the neonate's breathing pattern. A full-term newborn's breathing pattern is predominantly:

A) "Babies usually breathe in and out through their noses so they can feed without choking.":
Newborns are obligate nasal breathers, meaning they primarily breathe through their noses rather than their mouths, which helps coordinate breathing with feeding. This nasal breathing mechanism helps prevent aspiration and ensures that babies can feed while still breathing. It is perfectly normal for a baby to primarily use their nose for breathing, especially in the early days of life, and no cause for concern should be raised about small nasal openings unless the baby is showing signs of respiratory distress.

B) "You are right. I will report the baby's small nasal openings to the pediatrician right away.":
A small nasal opening is common in newborns and is not usually a cause for alarm unless it interferes with breathing, feeding, or shows signs of a more significant anatomical issue. There is no immediate need to report it unless the baby is having trouble breathing or feeding. The nurse should offer reassurance instead.

C) "Everything about babies is small. It truly is amazing how everything works so well.":
While this response may seem comforting, it is not very informative. It dismisses the mother’s concern rather than providing a clear and educational explanation. Reassuring the mother with factual information about why babies breathe through their noses and how this works effectively for them would be more helpful.

D) "The baby does rarely open his mouth but you can see that he isn't in any distress.":
This response minimizes the importance of the mother’s question and doesn’t fully address her concern. While it’s true that babies rarely open their mouths to breathe, the explanation needs to focus on the physiological reasoning behind it. The nurse should also reassure the mother that nasal breathing is normal in newborns and not typically a concern unless signs of distress are present.

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.
