A nurse is teaching a client at a prenatal clinic. The client shares that they have family members diagnosed with schizophrenia and wants to know how they can reduce their baby's risk of developing schizophrenia. Which of the following information should the nurse include?

Choice A reason: Calorie restriction during pregnancy is not a recommended preventive measure and may actually harm fetal development by causing malnutrition. Choice B reason: Maternal viral infections during pregnancy, such as influenza, have been associated with an increased risk of schizophrenia in offspring. Preventing infections through vaccination, hygiene, and avoiding exposure is a protective measure. Choice C reason: Iron deficiency should be prevented, not encouraged, since adequate maternal nutrition supports healthy fetal brain development. Limiting iron intake would not reduce schizophrenia risk and could increase complications. Choice D reason: While teenage pregnancy carries social and medical risks, it is not directly linked to increasing schizophrenia risk in offspring compared to maternal infections during pregnancy.
