Final answer:
The nurse interviews the patient to identify the cause of noncompliance with the prescribed regimen for diabetes management based on Orem's theory of self-care deficit. This enables the nurse to provide tailored education, support, and interventions to address the patient's specific needs and promote self-care.
Step-by-step explanation:
The nurse's behavior of interviewing the patient to identify the cause of noncompliance with the prescribed regimen for diabetes management is based on Orem's theory of self-care deficit.
Orem's theory emphasizes that individuals have the ability and responsibility to engage in self-care activities to maintain their health and manage their own condition.
By conducting an interview, the nurse aims to understand the patient's barriers, challenges, and beliefs that contribute to noncompliance. This information enables the nurse to provide tailored education, support, and interventions to address the patient's specific needs and promote self-care.
