We’ve spent the week with people who perform some of the toughest work there is – the professionals and families who care for the sick and dying. We conclude with a road trip to the south side of Des Moines. Correspondent Rob Dillard rides along with a home health nurse as she makes one of her 20 or so weekly patient visits. She delivers a style of health care reminiscent of bygone days when medical personnel often arrived at their patients’ doors to provide services. This kind of direct care is still in demand for those who are unable to venture far from home.
