A nurse is reinforcing teaching about appropriate exercises during pregnancy with a client who is at 24 weeks of gestation. Which of the following statements indicates a need for additional teaching?

Choice A reason:

Infection is not prevented by vitamin K administration. Vitamin K is needed for blood clotting, not for fighting infections. Newborns are given vitamin K injections to prevent a serious disease called hemorrhagic disease of the newborn (HDN), which is caused by bleeding in the brain or other organs.

Choice B reason:

Hyperbilirubinemia is not prevented by vitamin K administration. Hyperbilirubinemia is a condition in which there is too much bilirubin in the blood, causing jaundice. Bilirubin is a yellow pigment that is produced when red blood cells break down. Vitamin K does not affect the production or breakdown of bilirubin.

Choice C reason:

Bleeding is prevented by vitamin K administration. Vitamin K is needed for the synthesis of several clotting factors that help stop bleeding when there is an injury. Newborns have very low levels of vitamin K in their bodies because they do not get enough from the placenta or breast milk, and they do not have enough bacteria in their intestines to produce it. This puts them at risk for VKDB, which can cause life-threatening bleeding in the brain or other organs.

Choice D reason:

Potassium deficiency is not prevented by vitamin K administration. Potassium is an electrolyte that is important for nerve and muscle function, as well as fluid balance. Vitamin K does not affect the absorption or excretion of potassium.

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.
