Which of the following is NOT a category of nursing diagnosis?

The option deemed correct, "preventive diagnosis," is not recognized as a formal category of nursing diagnosis in the NANDA-I classification system. Nursing diagnoses are organized into specific categories that guide nurses in identifying patient needs and planning care.

Risk diagnosis refers to conditions where a patient is at risk of developing a problem due to certain vulnerability factors. Actual diagnosis signifies a diagnosis that is currently manifesting in a patient, showing signs and symptoms. Wellness diagnosis pertains to individuals or groups who are in a state of optimal health and are ready to enhance their well-being.

The absence of "preventive diagnosis" from the established categories highlights its non-recognition within the formal framework of nursing diagnoses. This reinforces the importance of understanding the officially recognized categories to ensure appropriate assessment and intervention in patient care.
