What is a probable nursing diagnosis?

According to NANDA International (NANDA-I), a risk nursing diagnosis is a clinical judgment concerning the susceptibility of a person, family, or community to develop an undesirable human response to health conditions. A probable nursing diagnosis is not a formal type but rather a term for a suspected problem requiring further data collection to confirm or rule it out.

Quick Summary

A probable nursing diagnosis refers to a suspected patient problem that requires further assessment and data collection by a nurse before it can be confirmed as a definitive diagnosis and included in the care plan.

Key Points

• Definition of Probable Nursing Diagnosis: A working term for a suspected health problem that a nurse identifies during an assessment, requiring further data collection to confirm or rule out.

• Probable vs. Confirmed Diagnosis: Unlike a problem-focused diagnosis, a probable diagnosis lacks sufficient evidence to be formally confirmed and documented in the care plan.

• Part of the Assessment Process: It serves as a hypothesis during the assessment phase, directing the nurse's focus and indicating the need for more comprehensive data gathering.

• Guides Care Plan Development: By identifying a potential issue, it allows nurses to prioritize further assessment and formulate a more specific and effective care plan once confirmed.

• Reflects Clinical Judgment: The use of a probable diagnosis highlights the nurse's critical thinking skills in recognizing patterns and potential health vulnerabilities in a patient.

• Distinct from Medical Diagnosis: Unlike a medical diagnosis, which identifies a disease, a nursing diagnosis, even a probable one, focuses on the patient's human response to a health condition.

Defining a Probable Nursing Diagnosis

While the North American Nursing Diagnosis Association (NANDA-I) provides a standardized list of approved diagnoses, the term "probable nursing diagnosis" is a practical label used by nurses during the assessment phase. It is not a formal diagnostic category but rather a working label for a suspected problem. It indicates that the nurse has identified certain cues suggesting a potential issue, but insufficient data exists to confirm a definitive problem-focused or risk diagnosis. This working diagnosis serves as a flag for the healthcare team, signaling the need for more focused data collection and observation.

The Role of Assessment in Formulating Diagnoses

The process of identifying a probable nursing diagnosis begins with the nursing assessment, where nurses gather subjective and objective data. Based on these findings, a pattern may indicate a potential health issue. For example, a post-operative patient refusing to mobilize might lead a nurse to consider a probable diagnosis like Acute Pain or Impaired Physical Mobility, requiring further data collection to confirm.

Distinguishing Probable from Confirmed Diagnoses

A confirmed problem-focused diagnosis is supported by sufficient defining characteristics, whereas a probable diagnosis is a placeholder to communicate a clinical suspicion and guide further investigation. It prevents premature intervention based on incomplete information.

Types of NANDA-I Diagnoses

Understanding formal NANDA-I classifications is essential. These include:

• Problem-Focused (Actual) Diagnosis: Identifies an existing problem based on defining characteristics (e.g., Ineffective Airway Clearance related to increased secretions as evidenced by ineffective cough and adventitious lung sounds).
• Risk Diagnosis: Identifies potential problems based on risk factors (e.g., Risk for Falls as evidenced by age greater than 65 years and history of unsteady gait).
• Health Promotion Diagnosis: Clinical judgment about a desire to increase well-being.
• Syndrome Diagnosis: A cluster of diagnoses occurring together.

For confirmed diagnoses, the PES format (Problem, Etiology, Signs/Symptoms) is often used. A probable diagnosis lacks the confirmed related factors and defining characteristics of the PES format.

Nursing Diagnosis: Probable vs. Problem-Focused vs. Risk

The table below highlights the key differences:

Aspect	Probable Nursing Diagnosis	Problem-Focused Nursing Diagnosis	Risk Nursing Diagnosis
Timing	Initial phase of assessment; suspected problem.	Problem is currently present based on collected data.	Problem does not yet exist, but vulnerability is present.
Supporting Data	Insufficient defining characteristics to confirm; requires more data.	Sufficient defining characteristics observed.	Supported by identified risk factors.
Linkage	Label used for suspicion; not formally linked with related factors or defining characteristics.	Written with "related to" (etiology) and "as evidenced by" (defining characteristics).	Written with "as evidenced by" followed by risk factors.
Intervention Goal	Gather more data to confirm or rule out the suspected diagnosis.	Address the existing problem and alleviate the signs/symptoms.	Implement preventative measures to minimize or eliminate risk factors.

Example Scenarios

1. Suspected Problem: A patient with heart failure reports breathlessness and fatigue. The nurse observes slightly increased respirations. Probable Diagnosis: Possible Ineffective Breathing Pattern. Nurse's Action: Monitor closely and assess for more signs to confirm.
2. Confirmed Problem: The same patient's respiratory rate increases, they report shortness of breath, and crackles are heard. Problem-Focused Diagnosis: Ineffective Breathing Pattern related to fluid accumulation in lungs as evidenced by shortness of breath at rest, increased respiratory rate, and bilateral crackles. Interventions would target improving breathing.
3. Potential Problem: An elderly patient with a recent fall is unsteady and lives alone. Risk Diagnosis: Risk for Falls as evidenced by advanced age, unsteady gait, and living alone. Interventions would focus on fall prevention.

The Iterative Nature of the Nursing Process

Identifying a probable diagnosis is a step within the dynamic nursing process. It leads to further assessment and planning. The nurse continues to evaluate the patient's response, potentially revising the diagnosis, ensuring responsive and flexible care.

The Conclusion: The Role of Clinical Judgment

A probable nursing diagnosis is a product of the nurse's clinical judgment, acting as a crucial tool in complex healthcare settings. It helps ensure potential problems are not missed, guiding the diagnostic process towards confirmed diagnoses and effective care plans.

Frequently Asked Questions

How is a probable nursing diagnosis different from a medical diagnosis?

A probable nursing diagnosis is a working label for a suspected patient response to a health condition, guiding nursing care and assessment. A medical diagnosis, made by a physician, identifies a specific disease or pathology.

What is the next step after identifying a probable nursing diagnosis?

The next step is to gather more data and perform further assessments. This allows the nurse to either confirm the diagnosis as a problem-focused or risk diagnosis, or to rule it out completely.

Can a probable nursing diagnosis be a risk diagnosis?

Yes, a probable diagnosis can be a suspected risk diagnosis. It indicates that the nurse has identified potential risk factors but needs more information to confirm the patient's vulnerability and formally document it as a risk diagnosis.

Is a probable nursing diagnosis included in the patient's official care plan?

Typically, no. A probable nursing diagnosis is a preliminary or working diagnosis used during the assessment phase. Only confirmed problem-focused, risk, or health promotion diagnoses, with sufficient supporting evidence, are included in the formal care plan.

What happens if a probable nursing diagnosis is never confirmed?

If further assessment reveals insufficient evidence to support the suspected diagnosis, the nurse will discard the probable diagnosis and focus on other confirmed diagnoses or continue monitoring the patient.

Why is it important for nurses to document a probable diagnosis?

Documenting a probable diagnosis, even if not official, is important for communication within the healthcare team. It alerts other nurses to the need for further assessment and focused observation, ensuring continuity of care.

How does the NANDA-I framework relate to probable nursing diagnoses?

The NANDA-I framework provides the standardized, evidence-based language for formal nursing diagnoses. A probable diagnosis is a preliminary, informal step that uses clinical judgment to identify which NANDA-I labels might apply to the patient's situation.
