Key terms with definitions appear at the beginning of each chapter and are in bold print throughout the text. Chapters are organized into units. The units follow the principle that learning proceeds from the simple to the complex. The concepts, principles, and procedures integral to other activities and functions are presented first. Contents and skills that are easy to learn and basic to the role of assistive personnel are then presented.
More complex content follows.
Unit titles reflect the assistive role. Icons in section headings alert the reader to an associated procedure. Procedure boxes contain the same icon. Labeling and color gradients differentiate the sections. Procedures traditional to the role of assistive personnel are shaded in blue.
