The nurse is reviewing a patient's plan of care, which includes the nursing diagnostic statement, Impaired physical mobility related to tibial fracture as evidenced by patient's inability to ambulate. Which part of the diagnostic statement does the nurse need to revise?

A) Etiology
B) Nursing diagnosis
C) Collaborative problem
D) Defining characteristic

The etiology, or related to factor, of tibial fracture is a medical diagnosis and needs to be revised. The nursing diagnosis is appropriate because the patient is unable to ambulate. A collaborative problem is an actual or potential physiological complication that nurses monitor to detect the onset of changes in a patient's health status; there is no collaborative problem listed. The defining characteristic (subjective and objective data that support the diagnosis) is appropriate for Impaired physical mobility.
