Which of the following is an example of functional nursing?

Functional nursing is a model of care where tasks are divided among nursing staff based on specific functions or roles, allowing for greater efficiency and specialization. This approach enables each nurse or nursing assistant to focus on particular aspects of patient care, which can enhance the overall workflow and improve the delivery of care. For example, one nurse may be responsible for administering medications, while another may handle hygiene care, and yet another may educate the patient about their condition. This division of labor can help ensure that all necessary tasks are performed thoroughly and in a timely manner, benefitting both patients and healthcare providers.

In contrast, the other options describe different models of care. For instance, when a single nurse is responsible for all aspects of patient care, it represents a more traditional nursing approach rather than functional nursing. A team of nurses working together implies a collaborative approach, which may not strictly align with the functional model. Lastly, the collaboration between nurses and physicians reflects a different type of organizational structure in healthcare that emphasizes teamwork rather than the division of specific functions among nursing staff. Therefore, the correct choice illustrates the essence of functional nursing by highlighting the clear distribution of duties.
