In an Effort to Control Costs and Maximize Revenues,the Rehabilitation

In an effort to control costs and maximize revenues,the Rehabilitation Unit at Cross Hospital reduces the number of its managers and flattens its organizational structure.Within a year,the number of adverse events on the units has doubled.This may be attributable to:

A) The overload of staff nurses.
B) Inability of staff at the bedside to make good choices.
C) A change in reporting systems.
D) Fewer clinical leaders and advocates for necessary resources.
