A nurse in an antepartum clinic is reinforcing teaching with a pregnant client about breastfeeding. Which of the following statements by the client indicates an understanding of the teaching?

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:

Rotavirus The nurse does not need to administer the Rotavirus vaccine in this scenario. Rotavirus immunization is typically given to infants between 2 and 6 months of age to protect against severe diarrhea caused by the virus. Since the child in question is 4 years old and up to date on current immunizations, this vaccine is not necessary.

Choice B reason:

Hepatitis B (Hep B) Similarly, the Hepatitis B vaccine is usually given shortly after birth and completed in a series of doses over the first year of life. Since the 4-year-old child is up to date on immunizations, the Hep B vaccine would have already been administered as part of the routine childhood vaccination schedule.

Choice C reason:

Varicella The Varicella vaccine, also known as the chickenpox vaccine, is typically given between 12 and 15 months of age and then again at 4 to 6 years old. Since the child is 4 years old and up to date on immunizations, it is now time for them to receive the second dose of the Varicella vaccine, making Choice C the correct answer.

Choice D reason:

Haemophilus influenza (Hib) The Haemophilus influenza (Hib) vaccine is usually given to infants starting at 2 months of age and is administered in multiple doses. By 4 years old, the child would have completed the primary series of the Hib vaccine. Therefore, there is no need to administer this vaccine again.
