Which of the following theories does NOT compose Orem's self-care deficit theory?

Orem's self-care deficit theory is composed of three main components: the theory of self-care, the theory of self-care deficit, and the theory of nursing systems. Each of these theories plays a crucial role in understanding the patient's self-care needs and the role of nurses in supporting those needs.

The theory of self-care focuses on the activities individuals initiate and perform on their own behalf to maintain life, health, and well-being. The theory of self-care deficit addresses the conditions under which nursing is needed when individuals cannot perform self-care activities effectively. The theory of nursing systems describes how nurses can provide care to support the patient's self-care efforts.

The concept of nurse-patient interaction, while important in nursing practice, is not explicitly one of the core components of Orem's theory. It does not define a separate theoretical framework within Orem's self-care deficit theory; rather, it is more about the practical application of nursing and how nurses engage with patients to help them manage their health. Thus, the option referring to the theory of nurse-patient interaction is not part of Orem’s established theories, making it the correct choice for this question.
