Iowa Code § 726.28: Wanton neglect or nonsupport of a dependent adult.

1. A caretaker commits wanton neglect of a dependent adult if the caretaker knowingly acts in a manner likely to be injurious to the physical, mental, or emotional welfare of a dependent adult. Wanton neglect of a dependent adult is a serious misdemeanor.

4. For the purposes of this section, “dependent adult” means a dependent adult as defined in section 235B.2, subsection 4, and “caretaker” means a caretaker as defined in section 235B.2, subsection 1.
