This popular textbook, now in a second edition, presents a clear introduction to the field and a skills-oriented approach to the core information needed by all advanced practice nurses. Students and clinicians -- whether nurse practitioner, clinical nurse specialist, midwife, or nurse anesthetist -- will learn to apply clinical decision making, care management, client education and advocacy, research, consulting, and writing and oral presentation skills to their APN role. They also will find information on professional issues, such as licensure and reimbursement. New to this edition are chapters on complementary therapies, collaboration, and ethical issues.
