Screening at 24 weeks of gestation reveals that a pregnant woman has gestational diabetes mellitus (GDM). In planning her care, the nurse and the woman mutually agree that an expected outcome is to prevent injury to the fetus as a result of GDM. The nurse identifies that the fetus is at greatest risk for:
low birth weight.
preterm birth.
macrosomia.
congenital anomalies of the central nervous system.
The Correct Answer is C
Choice A reason: Low birth weight is not a common complication of GDM, as the fetus tends to grow larger than normal due to the excess glucose and insulin in the blood. Low birth weight is more likely to occur in infants of mothers with preexisting diabetes or other conditions that affect placental function.
Choice B reason: Preterm birth is a possible complication of GDM, as the increased fetal size and the risk of maternal hypertension or infection may induce labor before term. However, it is not the greatest risk for the fetus, as preterm infants can survive with proper care and treatment.
Choice C reason: Macrosomia is the greatest risk for the fetus of a mother with GDM, as it is defined as a birth weight of more than 4000 g or 8 lb 13 oz. Macrosomia can cause difficulties during labor and delivery, such as shoulder dystocia, birth trauma, or cesarean birth. It can also increase the risk of neonatal hypoglycemia, jaundice, or respiratory distress.
Choice D reason: Congenital anomalies of the central nervous system are not a common complication of GDM, as they usually occur in the first trimester of pregnancy, before GDM is diagnosed or develops. Congenital anomalies are more likely to occur in infants of mothers with preexisting diabetes or other genetic or environmental factors.

Correct Answer is A
Explanation
Choice A reason: Variability refers to the fluctuations in the FHR that are irregular in amplitude and frequency. It reflects the balance between the sympathetic and parasympathetic nervous systems of the fetus. A normal variability is between 6 and 10 beats/min, which indicates a healthy and well-oxygenated fetus.
Choice B reason: Late decelerations are decreases in the FHR that begin after the peak of a contraction and return to the baseline after the contraction ends. They are caused by uteroplacental insufficiency, which means that the placenta is not delivering enough oxygen and nutrients to the fetus. Mild late decelerations are not reassuring and may indicate fetal hypoxia or acidosis².
Choice C reason: FHR should change as a result of fetal activity, such as movement, sleep, or stimulation. A change in the FHR indicates a responsive and well-oxygenated fetus. A lack of change in the FHR may indicate fetal distress or compromise.
Choice D reason: The average baseline rate is the mean FHR rounded to increments of 5 beats/min during a 10-minute window, excluding periods of marked variability, accelerations, or decelerations. A normal baseline rate is between 110 and 160 beats/min. A baseline rate between 100 and 140 beats/min is not necessarily abnormal, but it may indicate fetal bradycardia (slow heart rate) or tachycardia (fast heart rate), depending on the gestational age and other factors.
Correct Answer is A
Explanation
Choice A reason: Eating five small meals daily can help reduce heartburn in pregnancy by preventing overeating and reducing the pressure on the stomach from the growing uterus. It can also help maintain a steady blood glucose level and prevent nausea and vomiting.
Choice B reason: Lying down after each meal can worsen heartburn in pregnancy by allowing the stomach acid to reflux into the esophagus. It can also cause breathing difficulties and increase the risk of aspiration. The woman should avoid lying down for at least two hours after eating and elevate her head and chest when sleeping.
Choice C reason: Reducing the amount of fiber she consumes can cause constipation and hemorrhoids in pregnancy, which can increase the discomfort and pain. Fiber is important for maintaining a healthy digestive system and preventing gestational diabetes and preeclampsia. The woman should consume at least 25 grams of fiber per day from fruits, vegetables, whole grains, beans, and nuts.
Choice D reason: Substituting other calcium sources for milk in her diet can deprive the woman and the baby of essential nutrients, such as protein, vitamin D, and riboflavin. Milk is not a common cause of heartburn in pregnancy, unless the woman is lactose intolerant or allergic to dairy products. The woman should consume at least three servings of dairy products per day or take calcium supplements as prescribed.
