In the video for this chapter, we join an “older” couple during an ultrasound examination being administered to the expectant mother. Because of the mother’s age, she runs a higher risk of giving birth to a child with some kind of abnormality. While the doctor is performing the ultrasound, he explains that additional, more definitive information can be obtained by performing an amniocentesis, but it is a much riskier procedure. As you watch the video, think about any women you have known who have had an ultrasound or amniocentesis performed, or perhaps your own experience. Consider the inherent risks compared to the potential benefits, as well as the personal implications of taking action to end a pregnancy based on information gained from having one of these procedures performed. Briefly describe the basic process of an ultrasound examination. List the goals of an ultrasound exam that are mentioned in the video, its potential benefits, and its limitations.
