The nurse reviews diagnostic statements that a student wrote for this client. Which statement is written correctly?

## 보기

1. Inadequate nutritional intake related to major depressive disorder, as evidenced by a 3-kg loss in 4 weeks
2. Needs encouragement to eat related to a low appetite, as evidenced by eating about half of each meal served
3. Maladaptive coping related to an inability to cope with stress, as evidenced by staying in her bed most of the day
4. Ineffective sleep pattern related to worrying thoughts at bedtime, as evidenced by sleeping 3 to 4 hours nightly **✔ 정답**

## 해설

A problem-focused statement links a NANDA-I label to a cause nurses can treat ("related to") and to the client's signs and symptoms ("as evidenced by"). Common errors are using a medical diagnosis as the cause, writing a need or intervention as the problem, and restating the problem as its own cause.

## 심화 해설

Understanding the NANDA-I diagnostic statement structure

A correctly written problem-focused nursing diagnosis has three linked parts: the NANDA-I diagnostic label, the related to (r/t) factor that nurses can address, and the as evidenced by (AEB) signs or symptoms observed in the client. The diagnostic label names the human response, the related factor identifies the etiology or contributing condition, and the evidence grounds the diagnosis in objective or subjective data.

The related factor must be a condition that nursing interventions can modify or influence, not a medical diagnosis or a restatement of the problem itself. When the etiology is a medical disease, the nurse cannot treat the disease directly; instead, the nurse addresses the client's response to that disease. Similarly, writing the problem as its own cause creates a circular statement that provides no direction for care.

Analyzing each diagnostic statement

| Option | Diagnostic label | Related factor | Evidence | Problem |
| --- | --- | --- | --- | --- |
| 1 | Inadequate nutritional intake | Major depressive disorder | 3-kg loss in 4 weeks | Medical diagnosis used as etiology; nurses cannot treat the disease itself |
| 2 | Needs encouragement to eat | Low appetite | Eating half of each meal | Problem is written as a nursing intervention, not a NANDA-I label |
| 3 | Maladaptive coping | Inability to cope with stress | Staying in bed most of the day | Circular statement; the cause restates the problem |
| 4 | Ineffective sleep pattern | Worrying thoughts at bedtime | Sleeping 3 to 4 hours nightly | Correct: modifiable factor, observable evidence, valid label |

Watch out! Option 1 fails because major depressive disorder is a medical diagnosis. The nurse treats the client's response to depression, not the depression itself. A more appropriate related factor would be something like decreased appetite secondary to depressed mood or psychomotor retardation, which nursing interventions can address.

Watch out! Option 2 uses "needs encouragement to eat" as the diagnostic label. This is a nursing intervention or a goal, not a NANDA-I human response label. The correct label would be Imbalanced nutrition: less than body requirements or Inadequate nutritional intake.

Watch out! Option 3 is circular: "Maladaptive coping related to an inability to cope with stress" simply restates the problem as its own cause. The related factor should identify what is contributing to the maladaptive coping, such as inadequate support system or negative self-appraisal.

Why option 4 is correct

Option 4 follows the complete three-part structure. The label Ineffective sleep pattern is a recognized NANDA-I diagnosis describing a disruption in sleep quantity or quality. The related factor worrying thoughts at bedtime is a condition nurses can address through interventions such as relaxation techniques, cognitive reframing, sleep hygiene education, or scheduled worry time. The evidence sleeping 3 to 4 hours nightly is objective, measurable data that supports the diagnosis. This statement gives clear direction for planning care because the nurse knows what to target: the bedtime rumination that interferes with sleep onset.

Clinical application of standardized nursing language

The use of NANDA-I, NOC, and NIC taxonomies supports consistency and clarity in care planning. When diagnostic statements are written correctly, they guide the selection of appropriate outcomes and interventions. A well-formed diagnosis such as Ineffective sleep pattern related to worrying thoughts at bedtime as evidenced by sleeping 3 to 4 hours nightly allows the nurse to choose outcomes like improved sleep duration and interventions like teaching progressive muscle relaxation or limiting stimulating activity before bed. Conversely, poorly written statements with medical etiologies or circular logic create ambiguity and hinder the nursing process.

The quality of a nursing diagnosis depends on selecting a valid NANDA-I label, identifying a modifiable related factor, and providing observable evidence that links the label to the client's actual presentation. This three-part linkage is what makes the nursing process clinically meaningful and actionable.

NANDA-I Diagnostic Statement StructureProblem-focused diagnosis: label, modifiable cause, evidence
A correctly written problem-focused diagnosis links a NANDA-I label to a related factor nurses can treat and to as evidenced by signs or symptoms. The related factor must be modifiable by nursing interventions, not a medical diagnosis or a restatement of the problem.

Example of a correct statement: Ineffective sleep pattern related to worrying thoughts at bedtime as evidenced by sleeping 3 to 4 hours nightly. The cause is a cognitive-behavioral factor nurses can address through sleep hygiene, relaxation, or cognitive strategies.

CautionAvoid using a medical diagnosis such as major depressive disorder as the related factor, writing a nursing intervention as the problem label, or creating a circular statement where the cause repeats the problem.
