Ace the Nursing Theorists Challenge 2026 – Unlock Your Path to Nursing Success!

In Orem's theory, a self-care deficit occurs when the demands a person must meet to maintain health and manage illness exceed the person’s self-care agency. Self-care agency is the individual’s learned capacity to perform self-care activities—driven by knowledge, motivation, skills, and available resources to meet health needs. When these demands outstrip the person’s ability to care for themselves, a deficit is identified, and nursing steps in with a system that supports or partially or wholly takes over those self-care tasks. It’s not about willingness to learn, nor about the nurse’s time or hospital resources—the key issue is the patient’s own capacity to perform self-care.
