Which nursing activity exemplifies Orem's "supportive-educative" nursing system in the caring process?

The activity that best exemplifies Orem's "supportive-educative" nursing system is teaching the client how to perform self-injection of insulin. This approach aligns with Orem's theory that emphasizes the importance of nursing in supporting patients to achieve self-care. In this scenario, the nurse acts as a facilitator, providing the client with the necessary knowledge and skills to manage their own health condition, specifically in administering insulin, which is a vital aspect of diabetes management.

The supportive-educative system not only addresses the physical aspect of care but also empowers clients to take responsibility for their own health, promoting independence and ensuring they have the skills to manage their condition effectively. This educational process is essential in fostering confidence and competence in the client's ability to continue self-care after the nursing intervention has concluded.

In contrast, activities such as preparing a pre-op checklist or performing a catheterization focus more on direct patient management and clinical skills rather than on educating and empowering the patient. Similarly, assessing the client's health history primarily involves data collection and does not directly contribute to teaching the client how to take care of themselves, which is the core of the supportive-educative system.
