Final answer:
The practice of nursing in the 21st century has been influenced by the labor market trends, healthcare legislation such as the Affordable Care Act, shifts in industry sectors, globalization, and union dynamics, all shaping supply and demand for healthcare professionals.
Step-by-step explanation:
The external forces that have affected nursing practice in the twenty-first century include a variety of socio-economic factors. Notably, the labor market for nursing and other healthcare professionals has seen significant changes. An important influence has been the Affordable Care Act, which, by expanding access to healthcare for millions of Americans, has increased the demand for healthcare services and professionals.
Additionally, evolving factors such as the shift from manufacturing to service industries, the force of globalization, increased competition from foreign producers, and evolving attitudes toward unions due to workplace protection laws have all impacted nursing practice and the healthcare labor market.
These dynamics create challenges and opportunities in the market for healthcare professionals. With the supply and demand of qualified nursing staff undergoing real change, healthcare institutions must adapt to the increasing need for skilled nurses. The demand for nursing services is further fueled by the aging population, technological advancements in healthcare, and the necessity of delivering high-quality healthcare services on a broader scale.
