A nurse is assisting in the admission of a client who had recently given birth and is presenting to the emergency department with acute opioid toxicity. Which of the following findings should the nurse expect?

Choice A reason: The correct answer is choice A. The nurse should expect the presence of the Moro reflex in a 6-month-old infant. The Moro reflex is a normal primitive reflex seen in infants up to about 6 months of age. When the infant experiences a sudden loss of support or a loud noise, they react by extending their arms and legs and then pulling them back in, as if trying to grasp onto something. This reflex is an important indicator of the baby's neurological development.

Choice B reason:

The birth weight doubling by 6 months of age is a typical growth milestone for infants. However, this statement is not correct in the context of the question, as it is not something the nurse should "expect” during a well-child visit. Instead, it is a general developmental milestone that healthcare providers monitor over time.

Choice C reason:

The correct answer is choice C. The nurse should expect the posterior fontanel to be closed in a 6-month-old infant. Fontanels are soft spots on a baby's skull that allow for brain growth during early development. The posterior fontanel, located at the back of the head, is typically closed by 6 months of age.

Choice D reason:

The correct answer is choice D. At 6 months of age, many infants can sit unsupported. However, not all infants achieve this milestone at the exact same age. Some may achieve it a bit earlier, while others might take a little more time. It is essential for the nurse to assess the infant's developmental progress and provide appropriate guidance to the parents.

Choice E:

The correct answer is choice E. By 6 months of age, some infants may be able to move from their back to their front. This is usually accomplished through rolling over. However, like other developmental milestones, the age at which infants achieve this can vary. Therefore, while the nurse may expect this ability in some infants, it is not something that all 6-month- old infants will have mastered at the time of the well-child visit.

Choice A reason:

The nurse should not reinforce to the client that they should not breastfeed after delivery. Group B streptococcus (GBS) is not transmitted through breast milk. It is crucial for infants born to GBS-positive mothers to receive appropriate prophylaxis, but breastfeeding is not contraindicated.

Choice B reason:

The nurse should maintain contact precautions for the client. Group B streptococcus is a highly contagious bacterium, and taking precautions can help prevent its transmission to other patients and healthcare workers.

Choice C reason:

The nurse does not need to obtain a pharyngeal culture from the client. Group B streptococcus colonization typically occurs in the genital and gastrointestinal tracts, not in the pharynx. Therefore, a pharyngeal culture would not be relevant in this situation.

Choice D reason:

This is the correct action the nurse should take. The client tested positive for group B streptococcus, which puts the newborn at risk of infection during labor and delivery. The standard protocol is to administer intravenous antibiotic prophylaxis to the mother during labor to reduce the risk of transmission to the baby.
