A nurse is assessing a postmature infant.
Which of the following findings would the nurse expect? (Select all that apply.)

Choice A rationale

The presence of Rh factor in the mother's blood and absence in the newborn’s does not lead to antibody formation targeting fetal red blood cells directly. Rh incompatibility arises when the mother lacks the Rh factor and forms anti-Rh antibodies against the Rh-positive fetal blood. This leads to hemolysis and hyperbilirubinemia in affected newborns.

Choice B rationale

Anti-A and anti-B antibodies are associated with ABO incompatibility, not Rh incompatibility. ABO incompatibility can cause mild hemolysis but does not lead to severe hyperbilirubinemia seen in Rh incompatibility. Rh incompatibility specifically involves anti-Rh antibodies produced by Rh-negative mothers targeting Rh-positive fetal red cells.

Choice C rationale

Receiving a transfusion with Rh-negative blood would not trigger Rh incompatibility. Rh incompatibility is driven by maternal sensitization to Rh-positive fetal blood during pregnancy or delivery, leading to antibody formation and subsequent hemolysis in future Rh-positive pregnancies.

Choice D rationale

When the mother lacks the Rh factor (Rh-negative), she can produce anti-Rh antibodies upon exposure to Rh-positive fetal blood. These antibodies cross the placenta and attack fetal red blood cells, causing hemolysis and hyperbilirubinemia. This process is the hallmark of Rh incompatibility-related pathology.

Choice A rationale

Teaching the child how to use an inhaler supports self-management but does not address developmental readiness for independent inhaler use. At five years old, children often require supervision due to incomplete cognitive and motor development.

Choice B rationale

Providing information to the caregiver about child development stages clarifies expectations for independent inhaler use. This knowledge aligns with the protective factor of ensuring developmentally appropriate interventions for pediatric asthma management.

Choice C rationale

Community resources offer support but do not directly relate to the child's ability to use the inhaler without supervision. While beneficial, this option does not prioritize the developmental readiness aspect of pediatric care.

Choice D rationale

Referring the caregiver to an asthma educator focuses on skill-building and education but overlooks the specific developmental readiness of the child. Direct caregiver education on developmental milestones is more impactful in this context. .
