Healthcare encompasses all systems of the human body from head to feet. Perhaps, the most difficult of them all is the mental health of the entire person. In this case, professionals who specialize in caring for patients with mental disorders are beneficial. Such professionals specializing in studying mental disorders are called mental healthcare professionals. The psychiatric technician (PTC) is one of the many healthcare professionals specializing in mental health. To be a PTC, requires at least one year training in both classroom and clinical supervision in a medical facility and passing the licensure examination in some states of the U.S.A. This book contains practice questions with rationales broadly and explicitly covering basic nursing and administration of care, behavior management, legal and professional responsibilities, medication, psychosocial assessment and intervention, medication, anatomy and physiology, medical terminology, nutrition, mental disorders (developmental disability disorders, anxiety disorders, affective disorders, organic brain syndromes, mood disorders, personality disorders, eating disorders, substance abuse disorders, schizophrenia, sexual disorders), and other important topics. It is not intended to reflect the exact questions of the Board examination. The author's intention is to provide effective review material for the reader. Various levels of difficulty are reflected in this book. There are easy, moderate, and difficult questions.
