A nurse is collecting data from a 6-month-old infant in the well child clinic.
Which of the following findings should the nurse expect?
Infant's birth weight is tripled.
Lateral incisors are present.
Posterior fontanel is closed.
Infant sits well without support.
The Correct Answer is C
Choice A rationale
The infant's birth weight typically doubles by 4-6 months and triples by 1 year of age. If an infant's weight has tripled at 6 months, it may indicate overnutrition or an underlying health condition.
Choice B rationale
Lateral incisors usually appear between 9 to 13 months. At 6 months, the central incisors are more likely to be emerging.
Choice C rationale
The posterior fontanel typically closes by 2 to 3 months of age. Therefore, by 6 months, it is expected to be closed.
Choice D rationale
Infants usually sit without support around 8 months. At 6 months, they may sit with support or briefly without support but not consistently.

Correct Answer is A
Explanation
Choice A rationale
Applying a sterile, moist dressing on the sac helps prevent infection and keeps the tissue moist, promoting healing.
Choice B rationale
Monitoring the infant's temperature rectally can increase the risk of infection and is not recommended.
Choice C rationale
Encouraging the guardian to cuddle with the infant is important for bonding but doesn't directly address the care of myelomeningocele.
Choice D rationale
Maintaining the infant in a supine position can put pressure on the sac, increasing the risk of rupture and infection.
Correct Answer is A
Explanation
Choice A rationale
Babies at around 6 months are developing object permanence and might experience anxiety if they cannot see familiar faces, such as their mother's due to the mask.
Choice B rationale
Hunger is a common cause of crying in infants but doesn't specifically relate to the scenario provided regarding the mask.
Choice C rationale
Cold can cause discomfort in infants, leading to crying, but this is more of a general response and not directly related to the mask scenario.
Choice D rationale
Stress can cause crying, but the specific trigger in the scenario is the mother's masked face, causing potential anxiety.
