Observation of the level of function is different from what a nurse learns about function during the interview. A nurse observes what the patient does, such as self-feeding or making a decision, rather than what the patient says he or she can do. The level of function involves a person's ability to perform during everyday activities. Observation of the patient's behavior for level of function differs from a physical assessment. The hands-on physical examination measures the extent of function through measures such as range of motion and muscle strength. Verbal behavior is what the patient says. A nursing diagnosis would be self-care deficit.
