Defining Nursing: An Overview

Nursing, at its core, is a healthcare profession centered around the care of individuals, families, and communities to help them attain, maintain, or recover optimal health and quality of life. Nurses are critical in every aspect of healthcare, providing a bridge between patients and the complex medical systems they navigate. The profession encompasses a wide range of practice areas, from direct patient care to research, education, and leadership roles.

The History of Nursing

The roots of nursing can be traced back to ancient civilizations, where care for the sick was often managed by religious orders and charitable organizations. The modern nursing profession began to take shape in the 19th century, significantly influenced by figures such as Florence Nightingale. Her contributions during the Crimean War and her subsequent establishment of nursing schools laid the foundation for nursing as a respected and formalized profession.

  • Collaborating with other healthcare professionals
  • Advocating for patients' needs and rights
