A nurse professor is educating nursing students on The American Nurses Association's recommendation to use assistive devices for safe patient handling. The nurse professor judges the teaching to be effective when one of the students state: a. ""Research indicated that patients were being injured by falls during transfers."" b. ""Research indicated that back injuries in staff nurses were occurring even with good body mechanics."" c. ""Research showed an increased number of lawsuits resulted from patient falls."" d. ""Research uncovered reports from state boards of nursing showed increased back injuries."""
