Nurses face several challenges when implementing nursing theories in practice, including time constraints, lack of familiarity with theories, and organizational barriers. The fast-paced nature of healthcare often leaves little time for nurses to reflect on theoretical frameworks during clinical care. Additionally, if nurses are not well-versed in specific theories, they may struggle to apply them effectively. Organizational barriers, such as policies that do not support theoretical application or insufficient resources for ongoing education, can further hinder implementation. Lastly, the diversity of patient populations may require nurses to adapt theories, which can be complex and require additional training. Addressing these challenges requires ongoing education, leadership support, and a culture that values theoretical integration in nursing practice.
