Text, illustrations, and exercises are utilized in this set of learning modules to instruct nurses and other health care professionals in the symptoms and treatment of common medical disorders. The first module, by Fern A. Curran, discusses the causes of decubitus ulcers (i.e., bedsores), the physical damage they can do, and methods of preventing their occurrence on bedfast and wheelchair patients. The second module, by Grace Perkins, discusses the causes and symptoms of peptic ulcers to enable the learner to correctly diagnose the condition. The third module, by Ann Sutherland, teaches emergency medical technicians to identify the behavioral responses indicative of a patient's level of consciousness and how to report his/her patient assessment to a physician. The fourth module, by Ruth Traugot, describes eight varieties of shock and teaches students to recognize the signs of early and advanced shock. The fifth module, by Elizabeth J. Naugle, describes the clinical symptoms of respiratory disorders requiring medical attention and the observation of aseptic safeguards against infection. The sixth module, by Jan F. Zlotnick, describes the causes and symptoms of common post-operative respiratory complications. Each of the illustrated modules provides sequential reinforcement exercises with immediate feedback and concludes with a post-test and answer key. The time required to complete each module is specified, ranging from 20 to 50 minutes. (JP)
