16.3 NMBI Scope of Nursing and Midwifery Practice Framework
Key Takeaways
- The NMBI Scope of Nursing and Midwifery Practice Framework defines scope as the range of roles, functions, responsibilities, and activities which a registered nurse is educated, competent, and authorized to perform.
- Scope of practice is determined by four dynamic pillars: Competence, Professional Accountability and Responsibility, Support for Practice (clinical governance and PPPGs), and Context of Practice (patient acuity and environment).
- The NMBI Decision-Making Framework guides nurses through a structured five-step logical sequence to evaluate whether undertaking a clinical activity is safe, lawful, and appropriate.
- Expansion of nursing practice encompasses specialist and advanced roles, including Clinical Nurse Specialists (CNS), Registered Advanced Nurse Practitioners (RANP), and Registered Nurse Prescribers (RNP) of medicinal products and ionising radiation.
- In delegation, the delegating nurse retains ultimate professional accountability for the decision to delegate, assessing competence, and monitoring outcomes, while the delegatee (e.g., Healthcare Assistant) is responsible for executing the task safely.
NMBI Scope of Nursing and Midwifery Practice Framework
Core Regulatory Definition: The Scope of Nursing and Midwifery Practice Framework published by the Nursing and Midwifery Board of Ireland (NMBI) defines scope of practice as the range of roles, functions, responsibilities, and activities which a registered nurse is educated, competent, and has the authority to perform. Rather than enforcing static, rigid task lists, the Irish framework is dynamic, enabling nurses to adapt to advancing medical technology, evolving patient needs, and changing healthcare delivery models while maintaining public protection.
Every registered general nurse in Ireland is responsible for defining and maintaining their individual scope of practice, ensuring they never undertake clinical tasks for which they lack education, competence, or institutional authorization.
The Determinants of Scope of Practice
Under the NMBI framework, a nurse's scope of practice is shaped by four interrelated determinants:
+-----------------------------------------------------------------------------+
| FOUR DETERMINANTS OF SCOPE OF PRACTICE |
+-----------------------------------------------------------------------------+
| 1. Competence: Knowledge, skill, judgment, and personal attributes |
| 2. Accountability & Responsibility: Professional answerability |
| 3. Support for Practice: Governance, clinical policies (PPPGs), resources |
| 4. Context of Practice: Patient acuity, clinical setting, environment |
+-----------------------------------------------------------------------------+
1. Competence
Competence is defined by NMBI as the attainment of knowledge, intellectual capacities, practice skills, integrity, and ethical values required for safe, effective, and ethical practice. Competence is not a static achievement acquired upon graduation; it requires continuous reflection, education, and clinical practice. A nurse may be competent in adult intensive care hemodiafiltration but completely incompetent in paediatric cannulation.
2. Accountability and Responsibility
- Accountability: The statutory necessity to answer for the outcomes of professional actions, clinical decisions, and omissions to the patient, employer, regulatory body (NMBI), and the law. Accountability cannot be delegated or shared.
- Responsibility: The obligation to perform a specific clinical duty, intervention, or task successfully and safely. While responsibility for executing a task can be delegated, accountability for the decision to delegate remains with the nurse.
3. Support for Practice
A nurse cannot expand or practise their scope in a vacuum. Safe practice requires institutional support, including:
- Clear clinical governance structures.
- Validated institutional Policies, Procedures, Protocols, and Guidelines (PPPGs).
- Adequate staffing levels, skill mixes, and functional clinical equipment.
- Access to mentorship, clinical nurse specialists, and medical escalation.
4. Context of Practice
The clinical environment directly dictates the safety of an intervention. A clinical intervention that is safe on an intensive care unit with 1:1 nurse-to-patient staffing and continuous arterial line monitoring may be highly hazardous on a 34-bed general medical ward at night. Context factors include patient acuity, emergency preparedness, physical environment, and available multidisciplinary support.
The NMBI Decision-Making Framework
The NMBI Decision-Making Framework provides a structured, logical sequence of questions that every nurse must navigate before undertaking any novel, expanded, or unfamiliar clinical task:
+-----------------------------------------------------------------------------+
| NMBI DECISION-MAKING FLOWCHART |
+-----------------------------------------------------------------------------+
| Step 1: Definition of Nursing Practice |
| - Is the activity within the recognized definition of nursing? |
| │ [YES] |
| ▼ |
| Step 2: Legislation, Standards & Governance |
| - Supported by legislation, NMBI standards, and hospital PPPGs? |
| │ [YES] |
| ▼ |
| Step 3: Individual Competence |
| - Does the nurse possess the education, training, and competence? |
| │ [YES] |
| ▼ |
| Step 4: Patient & Environmental Assessment |
| - Has the nurse assessed patient acuity, risks, and environment? |
| │ [YES] |
| ▼ |
| Step 5: PROCEED WITH NURSING PRACTICE |
| |
| * If NO at ANY step -> DO NOT PROCEED! |
| Escalate, seek education, refer, or decline to undertake. |
+-----------------------------------------------------------------------------+
The Five-Step Decision Sequence
| Flowchart Step | Core Diagnostic Question | Required Action if "YES" | Mandatory Action if "NO" |
|---|---|---|---|
| Step 1: Definition | Is the activity consistent with the statutory definition and philosophy of nursing practice? | Proceed to Step 2. | Do not proceed. Refer to appropriate healthcare professional. |
| Step 2: Authority | Is the intervention supported by Irish legislation, NMBI standards, and local hospital PPPGs? | Proceed to Step 3. | Do not proceed. Develop local governance and approved policy before introducing. |
| Step 3: Competence | Does the individual nurse possess verified education, clinical training, and documented competence? | Proceed to Step 4. | Do not proceed. Decline task, arrange accredited education, and undertake supervised practice. |
| Step 4: Assessment | Has the nurse assessed the patient's individual condition, clinical risks, and the practice environment? | Proceed to Step 5. | Do not proceed until risk factors are mitigated or patient is stabilised. |
| Step 5: Outcome | Are all governance, competence, and patient safety criteria fulfilled? | Proceed with practice autonomously. | Stop. Escalate to Clinical Nurse Manager or medical team. |
Expansion of Practice & Advanced Practice Pathways
The NMBI framework facilitates career progression and clinical specialisation across distinct tiers of advanced practice:
Clinical Nurse Specialist (CNS)
A Clinical Nurse Specialist (CNS) is an experienced registered nurse who has completed specialist post-graduate education (typically at Level 9 Master's degree) in a specific clinical domain (e.g., Diabetes, Heart Failure, Tissue Viability, Oncology, Palliative Care). The CNS acts as an expert clinician, educator, researcher, and consultant, advising ward nurses and managing complex patient cohorts.
Registered Advanced Nurse Practitioner (RANP)
The Registered Advanced Nurse Practitioner (RANP) is the highest clinical nursing designation in Ireland, entered on the Advanced Nurse Practitioner Division of the NMBI Register. Educated at Master's or Doctoral level, the RANP practises as an autonomous, independent practitioner. Key competencies include:
- Conducting comprehensive physical and psychosocial examinations.
- Independently requesting and interpreting diagnostic imaging and laboratory investigations.
- Diagnosing acute and chronic conditions.
- Initiating and modifying clinical treatment plans.
- Admitting, managing, and discharging patients autonomously within an approved scope.
Registered Nurse Prescriber (RNP)
Registered General Nurses who undertake specialized accredited post-graduate training may join two distinct prescribing divisions of the NMBI Register:
- Nurse Prescriber of Medicinal Products: Authorized under the Irish Medicinal Products (Prescription and Control of Supply) Regulations 2007 (as amended) to prescribe medications autonomously within their collaborative practice agreement.
- Nurse Prescriber of Medical Ionising Radiation: Authorized under Irish ionising radiation regulations to refer patients for diagnostic radiographic procedures (X-rays) within their defined clinical specialty.
Principles of Safe Delegation
In modern acute and community wards, Registered General Nurses routinely work with Healthcare Assistants (HCAs) and student nurses. Delegation is defined as the transfer of responsibility for the performance of a task from one person to another while retaining accountability for the outcome.
+-----------------------------------------------------------------------------+
| THE FIVE RIGHTS OF SAFE DELEGATION |
+-----------------------------------------------------------------------------+
| 1. Right Task: Task matches HCA scope and routine ward protocol |
| 2. Right Circumstance: Patient is medically stable and predictable |
| 3. Right Person: HCA has verified training and proven competence |
| 4. Right Direction: Clear, unambiguous instructions given with parameters |
| 5. Right Supervision: Nurse monitors, evaluates, and documents outcome |
+-----------------------------------------------------------------------------+
Division of Accountability and Responsibility in Delegation
| Role | Regulatory Status | Legal Accountability & Clinical Responsibility |
|---|---|---|
| Delegating Nurse (RGN) | Registered Professional | Retains full accountability for the decision to delegate, verifying HCA competence, ensuring clear communication, monitoring patient stability, evaluating recorded findings, and taking corrective action. |
| Delegatee (HCA) | Healthcare Support Worker | Assumes responsibility for performing the delegated task safely, following standard procedures, recognizing abnormalities, and immediately reporting back to the registered nurse. |
Clinical Delegation Traps for the Aptitude Test
- Never Delegate Nursing Assessment: An RGN must NEVER delegate initial patient assessment, triage, nursing care plan formulation, or evaluation of clinical deterioration to an HCA. Delegating an abdominal assessment or respiratory evaluation of an unstable patient violates NMBI standards.
- Unstable Patients: While an HCA may record routine vital signs in a stable patient, vital signs recording in an acutely deteriorating patient (INEWS score ≥ 4 or single parameter red score of 3) must be performed or directly supervised by an RGN.
- Medication Administration: Administering medications (oral, subcutaneous, intravenous) is strictly restricted to registered nurses and cannot be delegated to healthcare assistants under Irish law.
A staff nurse on an acute medical ward is caring for a patient who has become tachypnoeic (respiratory rate 28/min) with an oxygen saturation of 91% on room air, generating an INEWS score of 5. The ward is extremely busy, and the nurse asks an experienced Healthcare Assistant (HCA) to perform a full respiratory assessment, titrate oxygen, and update the medical team via ISBAR. How does this delegation instruction violate the NMBI Scope of Practice Framework?
An emergency department staff nurse with two years of acute adult nursing experience is floated to the paediatric emergency bay during a severe staffing crisis. A medical registrar asks the nurse to perform an ultrasound-guided peripheral intravenous cannulation on a 4-month-old infant in septic shock. The nurse has certified competence in adult peripheral cannulation but has never received training or clinical assessment in paediatric cannulation or ultrasound guidance. What is the nurse's mandatory professional duty under the NMBI Decision-Making Framework?
A Registered General Nurse working on an acute orthopaedic ward wishes to expand their scope of practice to perform nurse-led postoperative wound debridement and application of topical negative pressure wound therapy (NPWT). Which sequence of actions correctly aligns with the NMBI Scope of Practice Framework before the nurse can independently perform this intervention?
