Final answer:
The nurse's focus on a caring relationship and the holistic well-being of the patient in teaching insulin administration reflects Jean Watson's caring philosophy, making Watson the correct answer.
Step-by-step explanation:
The nurse's caring approach and the development of a trusting relationship with the patient, accompanied by the sharing of feelings and a philosophical focus on the individual's needs in administering their own diabetes care, suggest that the nurse's actions are most in line with the philosophy of Jean Watson. Watson's Philosophy and Science of Caring emphasizes the caring relationship between the nurse and the patient and the holistic approach to patient care, considering the patient's subjective experiences as an essential component. This aligns with the scenario where the nurse engages in a supportive educational role, ensuring that the patient feels confident in self-administering insulin and dealing with the psychological aspects associated with a chronic condition such as diabetes.
