What is the difference between an expected finding and an unexpected finding on NCLEX?

An expected finding is a sign, symptom, or lab result that is consistent with the patient's known condition and does not require immediate intervention. Ankle edema in a patient with chronic heart failure is expected. An unexpected finding is one that is new, worsening, or inconsistent with the diagnosis, requiring immediate assessment and possible intervention. Sudden onset of confusion in a postoperative patient is unexpected and could indicate hypoxia, hemorrhage, or stroke.
