Which statement by parents of a fetus diagnosed with microcephaly indicates a need for further teaching?

The statement that indicates a need for further teaching is the belief that microcephaly is always caused by genetic factors. This statement is incorrect because microcephaly can arise from a variety of causes, including environmental factors, infections during pregnancy (such as Zika virus or rubella), exposure to toxins, and other non-genetic influences. While genetic factors can contribute to the condition, they do not encompass all potential causes. Understanding the multifactorial nature of microcephaly is crucial for parents, as it empowers them with the knowledge that there are various risk factors they can manage, especially during pregnancy.

The other statements reflect a more comprehensive understanding of microcephaly. Recognizing the potential for small head size is an accurate acknowledgment of the condition. Commitment to regular developmental assessments demonstrates an awareness of the importance of monitoring the baby's growth and development. Additionally, the intent to limit exposure to infections during pregnancy shows an understanding of preventive measures that can contribute to the health of the fetus.
