What is the most significant risk factor for clubfoot?

Choice A reason:

Hypoglycemia is a common complication for newborns whose mothers have diabetes mellitus. This is because the newborn's pancreas produces excessive insulin in response to the high glucose levels in the mother's blood during pregnancy. After birth, the newborn's glucose levels drop rapidly, while the insulin levels remain high, resulting in hypoglycemia. The nurse should monitor the newborn's blood glucose levels and signs of hypoglycemia, such as jitteriness, lethargy, poor feeding, and temperature instability.

Choice B reason:

Decreased RBC is not a likely complication for newborns whose mothers have diabetes mellitus. In fact, these newborns may have increased RBC due to chronic fetal hypoxia caused by placental insufficiency. The nurse should monitor the newborn's hematocrit and signs of polycythemia, such as ruddy skin, jaundice, and respiratory distress.

Choice C reason:

Hyperbilirubinemia is not a likely complication for newborns whose mothers have diabetes mellitus. In fact, these newborns may have increased bilirubin levels due to hemolysis of excess RBC and delayed hepatic clearance. The nurse should monitor the newborn's serum bilirubin levels and signs of jaundice, such as yellow skin and sclera, poor feeding, and lethargy.

Choice D reason:

Hypercalcemia is not a likely complication for newborns whose mothers have diabetes mellitus. In fact, these newborns may have hypocalcemia due to decreased parathyroid hormone secretion and increased calcium binding to albumin. The nurse should monitor the newborn's serum calcium levels and signs of hypocalcemia, such as jitteriness, tremors, seizures, and cardiac arrhythmias.

Choice A reason:

Attachment phase is not one of Rubin's phases of role attachment. Rubin's theory of maternal role adaptation describes three stages that the mother goes through during the postpartum period: taking in, taking hold and letting go.

Choice B reason:

Letting go phase is the last stage of Rubin's theory of role attachment. It occurs when the mother accepts her new role and gives up her old roles. She also comes to terms with the reality of the birthing experience and the characteristics of her baby.

Choice C reason:

Taking hold phase is the second stage of Rubin's theory of role attachment. It occurs when the mother becomes interested in caring for the infant and learning about her baby and herself. She may be critical about her care-giving abilities and need positive reinforcement.

Choice D reason:

Taking in phase is the first stage of Rubin's theory of role attachment. It occurs right after the birth of the child, when the mother is passive and focused on her own needs, especially sleeping and eating. She may have limited interactions with her infant and prefer to talk about her experiences during labor, birth, and pregnancy. This matches the description of the new mother in the question, so this is the correct answer.
