Practical Nursing, also known in California and Texas, as Vocational Nursing is a booming profession in the United States of America. A person who practices this profession is called an LPN or LVN. To be an LPN or LVN requires at least one year training in both classroom and clinical supervision in a medical facility and passing the NCLEX-PN licensure examination. An LPN and LVN is hired to care for people who are sick, injured, convalescent, or disabled under the direction and supervision of registered nurses and physicians. LPNs and LVNs are generalists and can work in any area of health care such as nursing homes, doctor's offices, and home care. This review book for the NCLEX-PN comes in volumes presented in outline format to enable easier retention of facts and faster conceptualization. Each chapter of the book contains quizzes and a glossary of medical terminologies with pronunciation to enable the reader to evaluate their knowledge and comprehension of the various subject areas. An answer key is located at the end of the book. In this particular volume, the concepts related to medical surgical nursing of the adult and aged are tackled. Additional volumes will be published in the coming months. These concepts include anatomy and physiology of the different body systems, definition of the different diseases and body conditions, assessment and data collection, diagnosis and treatment, and nursing management. Contents such as laboratory values and side effects from drugs may change from time to time.
