IOWA – Communities across Nebraska and Iowa have felt the impact of recent snowfall and below-zero temperatures, but that weather didn’t stop one Iowa hospice nurse. Tiffany McArdle, hospice nurse for St. Croix Hospice, told sister station KETV that in her seven years of working as a hospice nurse, she never imagined she would be walking through a blizzard to reach a patient, but she said she never doubted she would find a way to make it to the family in need on Sunday.
