The nurse administers vitamin K intramuscularly as prophylaxis to the newborn based on which of the following rationales?
Select one:

Choice A Reason: Episodes of hypoglycemia and hyperglycemia. This is because episodes of hypoglycemia and hyperglycemia are common complications of diabetes during pregnancy, which can affect both the mother and the fetus. Hypoglycemia is a condition where the blood glucose level drops below the normal range, which can cause symptoms such as sweating, trembling, hunger, confusion, or loss of consciousness. Hyperglycemia is a condition where the blood glucose level rises above the normal range, which can cause symptoms such as thirst, polyuria, fatigue, blurred vision, or ketoacidosis. Diabetes during pregnancy requires careful monitoring and management of blood glucose levels to prevent adverse outcomes such as fetal macrosomia, congenital anomalies, stillbirth, or neonatal hypoglycemia.

Choice B Reason: Postpartum hemorrhage. This is an incorrect answer that refers to a different complication that may occur after delivery, not during pregnancy. Postpartum hemorrhage is excessive bleeding from the uterus or genital tract after delivery, which can cause hypovolemic shock, anemia, or death. Postpartum hemorrhage can be caused by uterine atony, retained placenta, lacerations, or coagulation disorders.

Choice C Reason: Cerebrovascular accident (CVA). This is an incorrect answer that indicates a rare and severe complication that may occur during or after pregnancy, not specifically related to diabetes. CVA is also known as stroke, which is an interruption of blood flow to the brain due to ischemia or hemorrhage, which can cause neurological deficits or death. CVA can be caused by hypertension, preeclampsia-eclampsia, thrombophilia, or vascular malformations.

Choice D Reason: Acute vasospasm. This is an incorrect answer that suggests a different condition that may occur during pregnancy, not associated with diabetes. Acute vasospasm is also known as Raynaud's phenomenon, which is a disorder of blood vessels that causes them to narrow and reduce blood flow to the extremities in response to cold or stress, which can cause pain, numbness, or color changes. Acute vasospasm can be triggered by smoking, medications, or autoimmune diseases.

Choice A Reason: Macrosomic fetus is a fetus that weighs more than 4000 grams or 8 pounds 13 ounces at birth. It is not a common complication of teenage pregnancy, but rather of maternal diabetes, obesity, or a history of large babies.

Choice B Reason: Preeclampsia is a condition characterized by high blood pressure and proteinuria in pregnancy. It can cause serious complications for both the mother and the baby, such as seizures, organ damage, growth restriction, and placental abruption. Teenage pregnancy is a risk factor for preeclampsia, especially if the mother is younger than 15 years old.

Choice C Reason: Inadequate nutritional status of mother is a condition where the mother does not consume enough calories, protein, vitamins, minerals, or fluids during pregnancy. It can affect the growth and development of the baby and increase the risk of low birth weight, preterm birth, and birth defects. Teenage pregnancy is a risk factor for inadequate nutritional status of mother, as teenagers may have poor dietary habits, eating disorders, or limited access to food.

Choice D Reason: Cephalopelvic disproportion is a condition where the size or shape of the baby's head or body is too large to fit through the mother's pelvis. It can prevent normal vaginal delivery and require cesarean section. Teenage pregnancy is a risk factor for cephalopelvic disproportion, as teenagers may have smaller or immature pelvises that are not fully developed.
