NU 131 Exam 2 Comprehensive Study Guide: Nursing Roles, EBP, Law, and Ethics

Exam 2 Blueprint and Prioritization

Exam 2 for NU 131 consists of a 50-item blueprint composed of four primary content areas. Nursing and the Law represents the largest portion of the exam, accounting for 10 to 20 items, or approximately 20% to 40% of the total test. Nursing Ethics follows as a high-priority area with 8 to 15 items, making up 16% to 30% of the exam. Nursing Roles also holds a high priority, contributing 7 to 12 items or 14% to 24% of the content. Evidence-Based Practice (EBP) is the most focused area, with 2 to 6 items accounting for 4% to 12% of the examination.

Preparation priority should be weighted toward Nursing and the Law, specifically focusing on rules, legal documents, violations, and risk reduction strategies. Nursing Ethics requires mastery of ethical principles, complex dilemmas, and the professional code of conduct. For Nursing Roles, the emphasis is placed on the distinctions between the LPN/LVN and RN, the roles of various healthcare team members, and different care delivery models. For Evidence-Based Practice, study efforts should target the components of EBP, the sequence of steps involved in the process, types of research, and the specific role of the LPN. While law and ethics are primary, the lower end of their item ranges totals only 27 questions, meaning the exam mix can shift significantly, and no topic should be skipped.

Course Outcomes and Syllabus Cross-Reference

The materials for Exam 2 are aligned with six Course Student Learning Outcomes (CSLOs) and the Fall 2026 NU 131 syllabus. CSLO 1 focuses on identifying the LPN/LVN role in safe, quality, patient-centered care supported by EBP. CSLO 2 addresses advocacy through the use of ethical and legal principles, which forms the core of Unit 5. CSLO 5 describes collaboration with patients and the healthcare team, and CSLO 6 discusses the coordination of care using professional behaviors within various care-delivery models.

Course requirements for Unit 4 include understanding nursing roles, care-delivery models, and the impact of EBP. Learning targets involve differentiating RN and LPN roles, understanding team disciplines, and identifying functional, team, primary, and client-centered care models. Students must also state the three components of EBP, sequence its steps, and distinguish between quantitative and qualitative research. Unit 5 requirements center on legal and ethical implications, including the Nurse Practice Act (NPA) and its connection to scope, licensure, and accountability. Essential competencies include classifying laws, recognizing legal documents and torts, and applying ethical principles and the NALPN code to patient scenarios.

Nursing Roles and the Interdisciplinary Healthcare Team

The distinction between the Registered Nurse (RN) and the Licensed Practical/Vocational Nurse (LPN/LVN) is a critical exam topic. The RN is responsible for planning care and coordinating interdisciplinary activities. RNs provide complex care that requires specialized nursing knowledge and professional judgment. They initiate nursing actions and are responsible for teaching patients, families, and staff members. While they can assign appropriate routine or stable care to others, they remain accountable for the overall coordination of that care.

The LPN/LVN practices within the state Nurse Practice Act (NPA) and under the general supervision of an RN or an authorized provider. Their practice commonly involves caring for patients with predictable, stable, and chronic conditions. Instead of initiating teaching, LPNs reinforce or assist with teaching and are responsible for reporting observations or changes in the patient's condition. The LPN functions interdependently as an advocate, educator, collaborator, and direct-care provider.

Consulting the appropriate team member is vital for interdisciplinary care. The Physician or provider is responsible for diagnosis, treatment planning, and prescribing. The Pharmacist manages medications, evaluates interactions, and provides patient education on drugs. Physical Therapists (PT) focus on mobility, rehabilitation, and therapeutic exercise, while Occupational Therapists (OT) address Activities of Daily Living (ADLs), adaptive equipment, and home-function assessments. Dietitians or nutritionists perform nutrition assessments and diet planning. Social Workers handle psychosocial assessments, discharge planning, and the identification of community resources. Respiratory Therapists (RT) perform respiratory assessments and treatments.

Nursing Care Delivery Models

Functional nursing is a model where work is divided by specific tasks. It is highly efficient during staff shortages or emergencies because it allows tasks to be completed quickly. However, the greatest risk of this model is fragmented and non-holistic patient care. In contrast, team nursing is an RN-led group model where assignments are matched to the specific needs and skills of the staff. Team conferences are used to revise care plans as needed. This model is collaborative and flexible but can drift toward functional nursing when staff members feel rushed.

Primary nursing involves a primary RN who develops the care plan and retains 24-hour accountability for that plan. Associate RNs follow the established plan when the primary nurse is off-shift. This model promotes continuity and communication but is expensive and intensive for the RN staff; in this model, the LPN/LVN assists but does not lead. Client-centered care is a philosophy where patient preferences, needs, and values guide all clinical decisions. It includes the family and community and promotes a genuine partnership. This principle can be applied across every other delivery model.

Evidence-Based Practice (EBP) in Nursing

Evidence-Based Practice is a problem-solving approach to clinical decision-making that integrates three core components: the best available research evidence, clinical and nursing expertise, and patient values and preferences. EBP results in the development of best practices and clinical practice guidelines. It is specifically distinguished from practice based on "research alone" or performing tasks simply because that is "the way we have always done it."

The EBP process follows a strict six-step sequence. First, a clear clinical question must be asked. Second, the best research evidence is found. Third, that evidence is critically reviewed and evaluated. Fourth, the evidence is combined with clinical experience. Fifth, patient values are considered. Finally, the change is tested, and the outcomes are evaluated. A common distractor in testing is the idea that patient preference overrides evidence or vice versa; EBP explicitly requires the integration of both with expertise.

The role of the LPN/LVN and the nursing student in EBP involves maintaining a spirit of inquiry. This means asking why an action is performed and questioning routines that lack support. They must review current research and use evidence to support their care plans and interventions. Following agency protocols and procedures while collecting objective data to evaluate effectiveness is essential. Observations and evidence-informed concerns should be brought to the supervising RN while working within the legal scope of practice.

Research within EBP is categorized as quantitative or qualitative. Quantitative research is objective and focuses on numbers and measurable outcomes. It often involves comparing a control group to an experimental group, such as measuring the outcomes of a new drug across two groups. Qualitative research is subjective and focuses on experiences, meanings, and themes. It often utilizes interviews or observations, such as exploring how students experience growing clinical confidence.

Categories of Nursing Law and Regulatory Bodies

Nursing law is divided into three primary categories. Administrative law regulates licensure, nursing practice, nursing schools, health facilities, and government programs like Medicare and Medicaid. Civil law involves wrongs committed against individuals, which can lead to lawsuits and monetary damages; a civil wrong is referred to as a tort. Criminal law addresses wrongs against society and can result in fines or imprisonment, with felonies being more serious than misdemeanors.

The Nurse Practice Act (NPA) is a state law that defines the scope of practice, licensure requirements, and professional standards for nurses. Because this is state law, it varies by jurisdiction. The State Board of Nursing is the regulatory body that enforces the NPA. It oversees licensure, handles disciplinary actions, and sets standards for nursing education. Nurses must understand that the NPA defines what they are legally permitted to do.

Accountability, Delegation, and Professional Standards

Accountability in nursing involves taking full responsibility for one's actions as well as one's omissions. Safe performance includes seeking help when necessary, providing accurate reporting and documentation, evaluating patient outcomes, and engaging in lifelong learning. Standards of care are derived from several sources, including the NPA, facility policies and procedures, nursing journals and references, and professional organizations. These standards serve as legal benchmarks in practice.

Delegation is the transfer of performance for a specific task; however, it does not transfer the nurse's ultimate responsibility for patient safety. The nurse remains responsible for appropriate supervision and evaluation. The Five Rights of Delegation must be followed: the Right Task (legal and appropriate for the delegatee), Right Circumstance (safe for the specific situation), Right Person (trained and competent), Right Direction/Communication (clear and specific instructions), and Right Supervision (monitoring, follow-up, and evaluation).

Student nurses are legally held to the same standards as licensed nurses for their acts and omissions. They must ask for help, monitor patients closely, understand the NPA, and stay within their permitted scope. While a facility can narrow a student's duties through policy, it cannot expand those duties beyond what is permitted by state law. State boards investigate NPA violations, which can include incompetence, negligence, or substance misuse and diversion, potentially leading to license suspension or revocation.

Legal Implications and Mandatory Guidelines

Several specific laws and guidelines impact daily nursing practice. Good Samaritan laws may limit liability for healthcare personnel providing good-faith emergency aid, provided they act within their scope and without gross negligence. Laws against discrimination prohibit unfair treatment based on protected status and require reasonable disability accommodations. Sexual harassment involves unwelcome conduct; nurses must recognize these behaviors, avoid hostile environments, and report serious or repeated incidents.

Licensed healthcare personnel are mandatory reporters for suspected child abuse and must follow specific facility and state procedures. Patient rights must be protected, including dignity, privacy, autonomy, and the right to information and participation in healthcare decisions. National Patient Safety Goals emphasize the use of client identifiers, safeguards for medications, alarms, and infections, and the necessity of clear handoff communication during care transitions.

Legal Documentation and Patient Consent

The medical record is a legal document that must be charted objectively, accurately, and promptly. While the facility owns the physical or electronic record, the patient has the right to access the information. HIPAA (Health Insurance Portability and Accountability Act) protects health information and provides patients with rights concerning consent, notice, access, amendment, and accounting of their data. Confidentiality must be maintained by sharing information only with those directly involved in the patient's care.

Informed consent requires that a provider explains a procedure to the patient. The nurse's role is to witness the signature and verify that the patient is signing voluntarily and understands the information. If a patient indicates they have questions or do not understand, the nurse must stop and contact the provider. Nurses must never witness a signature they did not personally observe. For patients leaving the hospital against medical advice (AMA), an AMA release must be signed to document that the patient understands the risks; this requires the patient to have decision-making capacity.

Advance directives are legal documents that outline a patient's preferences for future care. A Living Will states desired treatments if the patient becomes unable to communicate. A Durable Power of Attorney for healthcare names a surrogate or agent to make decisions. POLST (Provider Orders for Life-Sustaining Treatment) are portable medical orders signed by a provider regarding resuscitation and treatment preferences. A DNR (Do Not Resuscitate) or AND (Allow Natural Death) order specifies that no CPR should be performed; these must be verified, documented, and communicated to the entire team.

Civil Law: Torts, Negligence, and Malpractice

Negligence is defined as the failure to act as a reasonable and careful person would in a similar situation. Malpractice is a form of professional negligence. For a malpractice claim to be successful, four specific elements must be proven. First is Duty, meaning the nurse owed a responsibility to the patient. Second is Breach, where the nurse failed to meet the established standard of care. Third is Causation, meaning the breach of duty directly led to harm. Fourth is Injury or Damages, which can be physical, emotional, or financial. An example is a failure to monitor a post-operative patient, leading to an undetected hemorrhage and subsequent death.

Intentional torts are specific legal violations. Assault is an action or threat that creates a fear of unwanted contact. Battery is the actual unwanted touching or treatment of a person. Defamation occurs through false or damaging communication; it is called slander when spoken and libel when written. Invasion of privacy refers to improper disclosure of or intrusion into private affairs. False imprisonment involves the unjustified restraint or detention of a patient without legal warrant.

Restraints, Incident Reporting, and Risk Reduction

Restraints or supportive devices should be used only after less restrictive measures have been attempted. Their use requires proper authorization and provider orders, as well as strict adherence to monitoring and documentation policies regarding hydration, toileting, mobility, and safety. Improper use of restraints can lead to legal exposure for false imprisonment or malpractice.

An incident report is a tool used by risk management to improve safety. It should be factual, timely, and concise, containing no personal opinions. A critical rule of nursing documentation is that the nurse should never chart that an incident report was completed in the patient's medical record. Instead, the nurse should chart the patient's assessment, the care provided, who was notified, and the patient's response to the event.

To reduce legal risk, nurses must maintain clinical competence and remain knowledgeable about their scope of practice, the NPA, and facility policies. Objective documentation and professional communication are essential. Building a respectful rapport with patients and protecting their confidentiality can prevent many legal issues. Additionally, nurses must manage fatigue and burnout, as impaired performance significantly raises the risk of errors and legal repercussions.

Nursing Ethics and Moral Principles

Ethics are professional and moral guidelines for conduct, often based on group consensus, whereas laws are enforceable rules established by the government. An ethical violation may result in professional discipline even if no law was broken. Ethical dilemmas occur when values or duties conflict, and while the law may set a minimum requirement, it does not resolve every moral conflict. Even if a nurse personally disagrees with a law, it must be followed.

Seven primary ethical principles are applied to nursing practice. Autonomy involves respecting the patient's informed choices and self-determination. Beneficence is taking action to promote the patient's good. Nonmaleficence is the requirement to avoid or minimize harm. Justice refers to treating people fairly and the equitable allocation of care. Veracity is the obligation to communicate truthfully. Fidelity involves keeping commitments and remaining faithful to professional duties. Confidentiality and privacy involve protecting a patient's personal space and information.

NALPN Code and Ethical Dilemma Resolution

The NALPN code outlines specific themes for LPN/LVN practice, including knowing and staying within one's scope, protecting privacy, and providing unbiased care to all patients. Nurses are expected to uphold high professional standards, remain current in their knowledge, and ensure they are fit for duty to protect both the patient and the reputation of the nursing profession.

Resolving an ethical dilemma involves a structured seven-step method. First, identify the conflict and the stakeholders involved. Second, gather all clinical facts, patient wishes, and applicable laws or policies. Third, name the competing principles (such as autonomy versus beneficence). Fourth, generate options and evaluate their likely consequences. Fifth, consult with the RN, provider, or ethics committee. Sixth, act within the scope of practice while communicating respectfully. Finally, evaluate the outcome of the action. A common intersection of law and ethics is the refusal of treatment by a competent patient; autonomy supports the refusal, and forcing treatment would constitute battery.

Unit 5 Concept Map Checklist and Rubric Requirements

The central concept of the Unit 5 concept map is "Nursing and the Law/Nursing Ethics." To achieve the highest rubric score, students must include six to seven key concepts with accurate details and explicit connecting phrases. Required branches include legal and ethical aspects (administrative/civil/criminal law), practice and licensure laws (NPA and Board of Nursing), and laws/guidelines affecting practice (mandatory reporting and patient rights).

Additional branches must cover legal documents (informed consent, HIPAA, and advance directives), violations of law (negligence and intentional torts), strategies for decreasing legal risk (competence and documentation), and ethical terms (the seven core principles). The rubric evaluates clarity of labels, accuracy of relationships, organizational hierarchy, depth of evidence through specific examples, and visual appeal.
