Which statement characterizes a nursing diagnosis?

• A. It is a formal statement of a health problem that nurses can legally and independently treat
• B. It is a disease diagnosis identified by tests
• C. It is a legal document for hospital accreditation
• D. It is a treatment plan

Answer: (A)

A nursing diagnosis is a formal clinical judgment about a patient’s actual or potential health problem that nurses are licensed to address independently, and it serves as the basis for planning and delivering nursing care. This means it describes how a patient is responding to a health issue—and what nursing actions can help—rather than labeling a disease or prescribing medical treatments. The statement that this problem can be legally and independently treated fits because it emphasizes the nurse’s scope of practice: identifying patient responses and guiding interventions within nursing care.

Medical diagnoses, by contrast, identify disease processes through tests and medical evaluation, not the patient’s response to health conditions that nursing care targets. A legal document for hospital accreditation is a separate administrative matter, not the clinical judgment guiding day-to-day care. A treatment plan is the set of actions chosen to address the nursing diagnosis; it comes after the diagnosis is defined. Understanding nursing diagnoses as patient-response statements helps explain why they are distinct from disease labels or formal treatment plans and why they are central to the scope of nursing practice.
