Final answer:
At 16 weeks gestation, the priority information a nurse should provide to a primigravid client is about the nutritional needs during pregnancy, as it is crucial for fetal development and the mother's health.
Step-by-step explanation:
The nurse reinforces teaching to a 15-year-old primigravid client at 16 weeks gestation during an initial prenatal visit. The priority information for the nurse to include would be d) Nutritional needs during pregnancy. Proper nutrition is crucial for fetal development and the health of the mother. It is important for the mother to understand what constitutes a balanced diet, which nutrients are particularly necessary during pregnancy, such as folic acid, iron, and calcium, and how much weight gain is healthy.
While other topics like breastfeeding techniques, infant CPR procedures, and car seat safety guidelines are important, they are more relevant later in pregnancy or after the baby is born. At 16 weeks, the client's immediate need is to ensure a healthy pregnancy, and understanding nutritional needs is integral to achieving this goal.
