Final answer:
Benner and Wrubel's theory of nursing is the most suitable for a nursing student who believes in the essence of 'Caring', as it aligns with the ethics of care that emphasizes the importance of caring and relationships in health care. The correct option is a.
Step-by-step explanation:
If a prospective nursing student believes that the essence of nursing is "Caring," then the theory most likely to meet her needs is Benner and Wrubel's theory of nursing. This theory is closely related to the ethics of care, which emphasizes the significance of caring and the relationships in health care.
Benner and Wrubel focus on the experiences of nurses and the development of nursing knowledge through caring practices, making it highly relevant to a student with such a belief.
Due to its alignment with the philosophy that nursing entails a deep concern with relations and caring practices, this perspective resonates with a student's view that caring is central to nursing.
Other theories, such as Roy's adaptation theory, Orem's self-care deficit theory, and Roger's theory, have different focal points. Roy’s theory focuses on the adaptability of patients in response to health and illness, Orem's theory emphasizes patient self-care, and Roger's theory revolves around the idea of self-concept and congruence.
While these models incorporate elements of care, they do not centralize the ethic of care as fundamentally as Benner and Wrubel’s theory does in relation to the nursing practice. Option a. is the correct one.
