False

A study of adults older than 65 years investigated the effect of the use of calming communication techniques by caregivers on the agitation level of patients experiencing stage 2 dementia.

In the United States during the 1970s, nursing practice included the use of granulated sugar to pack stage III and IV wounds based on the idea that bacteria would be less invasive of new tissue formation.
