The labor and delivery nurse understands that some neonates spontaneously take a breath once the head and chest is delivered. Which understanding does the nurse have for the neonate that requires chemical stimuli to breathe?

Correct Answer: C

Rationale: Step 1: Mild hypoxia and decreased pH stimulate the brain to initiate breathing in neonates. Step 2: This chemical stimuli trigger the respiratory centers in the brainstem. Step 3: Oxygen administration may not be necessary as the neonate's own respiratory drive is initiated by chemical stimuli. Step 4: Carbon dioxide administration is not needed as high levels can be harmful. Step 5: Suctioning is not used to stimulate breathing but to clear airways if necessary. Summary: Choice C is correct as it aligns with the physiological response of neonates to chemical stimuli for breathing, while the other choices are not relevant or could be potentially harmful.

Correct Answer: B

Rationale: The correct answer is B because newborns typically go through a period of deep sleep immediately after birth. This state is characterized by decreased responsiveness to external stimuli and lower respiratory and heart rates. It is important for the nurse to allow the neonate to naturally continue deep sleep as this is a normal physiological process. Picking up the neonate (choice A) may disrupt this important sleep state. Asking another nurse for assistance (choice C) may not be necessary at this point as the neonate's condition is likely normal. Notifying the caregiver (choice D) may cause unnecessary alarm as the neonate is most likely exhibiting normal behavior for this stage.

Correct Answer: C

Rationale: The correct answer is C because offering a sucrose-dipped pacifier during the nerve block procedure can help manage the newborn's pain by providing comfort and distraction through the sweet taste and sucking motion. Sucrose has been shown to have analgesic effects in newborns. Choice A is incorrect as a tourniquet is not recommended for circumcision. Choice B may help with calming but not specifically with pain management. Choice D is incorrect as numbing with ice before the nerve block may not be effective in providing adequate pain relief during the procedure.

Correct Answer: D

Rationale: The correct answer is D because the nurse does not mention the term "hyperbilirubinemia" to the mother. Instead, the nurse focuses on explaining the high level of unconjugated bilirubin causing jaundice. A: The nurse likely mentioned that the blood test does not indicate a pathological disease to reassure the mother that jaundice is a common condition in newborns. B: The nurse would have explained that the newborn's liver converts bilirubin to a water-soluble substance as part of the discussion on how bilirubin is processed in the body. C: An abundance of RBCs and their short lifespan contributing to jaundice would be relevant information that the nurse would provide to explain the underlying causes of the condition.

Correct Answer: A

Rationale: The correct answer is A because avoiding bottles helps maintain the baby's preference for breastfeeding, leading to a higher likelihood of continuing beyond 6 months. Using formula for every other feeding (choice B) introduces a different feeding method, potentially reducing breastfeeding duration. Offering water or formula after breastfeeding (choice C) can reduce the baby's interest in breastfeeding exclusively. A satisfied baby for 4 hours after feeding (choice D) does not necessarily indicate a longer breastfeeding duration as other factors like feeding frequency play a role.
