Final answer:
While both breastfed and formula-fed infants can develop eczema, it is not necessarily related to any of the factors mentioned in the question options. Breastfeeding can offer immunological benefits, but it does not guarantee protection against eczema.
Step-by-step explanation:
The question pertains to the expectation of a nurse regarding a 3-month-old infant treated for eczema. The answer to this question is not straightforwardly linked to the infant's prematurity status, feeding method, or the mother's gestational diabetes condition as eczema can develop from various factors, including genetics and environmental triggers. While both breastfed and formula-fed infants can develop eczema, some evidence suggests that breastfeeding may provide certain immunological benefits; however, it is not an assurance against eczema. Furthermore, the premature birth of an infant could lead to issues such as difficulty inflating the lungs due to insufficient production of pulmonary surfactant, but this is not directly related to the occurrence of eczema. Colostrum is crucial for a newborn as it helps boost the newborn's immune system. Antibodies are provided to the infant from the mother passively via the placenta and actively through breast milk, but the presence of these antibodies does not prevent eczema.
