What is the recommended method of administering hepatitis B vaccine to a newborn?
- A. Intramuscular injection
- B. Oral administration
- C. Topical application
- D. Subcutaneous injection
Correct Answer: A
Rationale: The correct answer is A: Intramuscular injection. Administering hepatitis B vaccine via intramuscular injection ensures proper absorption and immune response. Injecting into the muscle allows for efficient delivery to the bloodstream. Oral administration (B) is not effective as the vaccine may be degraded in the digestive system. Topical application (C) and subcutaneous injection (D) are not recommended for hepatitis B vaccine due to inadequate absorption and immune response.

Which of the following is a potential complication of neonatal respiratory distress syndrome?
- A. Hypoglycemia
- B. Pneumonia
- C. Patent ductus arteriosus
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D: All of the above. Neonatal respiratory distress syndrome can lead to complications such as hypoglycemia due to increased metabolic demands, pneumonia due to weakened immune system, and patent ductus arteriosus due to increased pulmonary blood flow. Hypoglycemia, pneumonia, and patent ductus arteriosus are all potential complications associated with neonatal respiratory distress syndrome. The other choices are incorrect as they do not encompass the range of potential complications associated with this condition.
Which of the following is a potential complication of meconium aspiration syndrome?
- A. Respiratory distress syndrome
- B. Hypoglycemia
- C. Jaundice
- D. All of the above
Correct Answer: A
Rationale: The correct answer is A: Respiratory distress syndrome. Meconium aspiration can lead to airway obstruction, inflammation, and surfactant dysfunction, resulting in respiratory distress syndrome. Hypoglycemia and jaundice are not directly associated with meconium aspiration syndrome. Therefore, choice A is the most appropriate complication.
A nurse is caring for a client who is 1 day postpartum and breastfeeding her newborn. The client reports sore nipples. Which of the following actions should the nurse take?
- A. Instruct the client to wait 4 hr between daytime feedings.
- B. Assess the newborn's latch while breastfeeding.
- C. Have the client limit the length of breastfeeding to 5 min per breast.
- D. Offer supplemental formula between the newborn's feedings.
Correct Answer: B
Rationale: The correct answer is B: Assess the newborn's latch while breastfeeding. Sore nipples in breastfeeding can be caused by improper latch, leading to discomfort for the mother. By assessing the newborn's latch, the nurse can identify any issues such as shallow latch or poor positioning that may be causing the soreness. This allows for timely intervention to improve the latch, alleviate nipple soreness, and promote successful breastfeeding.
Choice A is incorrect as spacing out feedings can lead to engorgement and decreased milk supply.
Choice C is incorrect as limiting breastfeeding time can affect milk production and hinder proper milk transfer.
Choice D is incorrect as offering formula may interfere with breastfeeding establishment and can decrease milk supply.
A nurse is assessing a newborn who is 16 hr old. Which of the following findings should the nurse report to the provider?
- A. Substernal retractions
- B. Acrocyanosis
- C. Overlapping suture lines
- D. Head circumference 33 cm (13 in)
Correct Answer: A
Rationale: The correct answer is A: Substernal retractions. Substernal retractions in a newborn can indicate respiratory distress, which is a critical finding that requires immediate attention from the provider to prevent complications. Acrocyanosis (B) is a common finding in newborns and usually resolves on its own. Overlapping suture lines (C) can be normal in newborns due to the molding process during birth. The head circumference of 33 cm (13 in) (D) is within the normal range for a newborn.
