Chapter 1: Nursing and The Health Care System

Nursing has a rich history that shaped modern healthcare. Florence Nightingale was a pioneer who believed in humane patient care and continuing education for nurses. In North America, nurses like Dorothea Dix, Clara Barton, and Lillian Wald expanded nursing into the community, providing care during wartime and to underserved populations. Throughout the 20th century, nursing evolved to include midwifery, prenatal care, and community health services.

Today, nursing is based on common goals of providing quality, evidence-based care. The nursing process is the foundation of nursing practice, and nurses work in various settings including hospitals, clinics, long-term care facilities, and home health. There are multiple educational pathways: practical nursing (LPN/LVN), registered nursing (RN), and advanced-practice nursing. Nursing care is delivered through different methods: functional nursing, team nursing, total patient care, and primary nursing.

The modern healthcare system includes different levels of care (preventive, acute, rehabilitative, long-term), and various types of insurance organizations like HMOs (Health Maintenance Organizations) and PPOs (Preferred Provider Organizations) that manage how patients receive care.

Chapter 2: Health, Illness, Stress, and Health Promotion

Health and Illness Concepts

Health is no longer viewed as just the absence of disease. Instead, it’s seen as a spectrum ranging from obvious disease through a state of optimum functioning in every aspect of life. This means someone can be partially healthy or unhealthy depending on their physical, mental, emotional, and social well-being.

Stages of Illness show how people progress through sickness, including the symptoms and behaviors they display. People’s health and illness behavior varies - some seek treatment quickly while others avoid doctors. Additionally, cultural influences greatly impact how people view health and illness, so nurses must be culturally sensitive.

The Holistic Approach

Nursing uses a holistic approach, meaning nurses care for the whole person - not just the illness - by considering physical, emotional, social, and spiritual needs. This approach is based on Maslow’s Theory of Basic Needs, which states that people have five levels of needs:

1. Physiological needs (breathing, food, water, sleep) - must be met first

2. Safety needs (security, protection, stability)

3. Love and belonging needs (relationships, friendship, connection)

4. Esteem needs (respect, confidence, recognition)

5. Self-actualization (achieving one’s potential)

Homeostasis and Adaptation

Homeostasis is the body’s attempt to maintain internal balance and stability. When the body faces stress, it must adapt to return to balance. The General Adaptation Syndrome describes how the body responds to stress in three stages:

1. Alarm reaction (initial response)

2. Resistance (body adapts and fights the stressor)

3. Exhaustion (if stress continues too long, the body becomes depleted)

Stress and Coping

A stressor is anything that causes stress - and it can be helpful or harmful depending on:

• How the person perceives it

• Their health and fitness level

• Previous life experiences and personality

• Available social support

• Personal coping mechanisms

People cope with stress through coping mechanisms and defense mechanisms (like denial, rationalization, repression). Stress reduction techniques like exercise, relaxation, and social support help manage stress.

Health Promotion and Illness Prevention

Healthy People 2020 is a government program with goals to:

• Increase quality and years of healthy life

• Eliminate health disparities

• Create environments that promote good health

• Promote healthy behavior across all life stages

Nurses play a key role in helping patients reduce stress through explanation, listening, answering questions, and providing privacy.

Chapter 3: Legal & Ethical Implications in Nursing

Legal Foundations

Law comes from several sources including constitutions, statutes (laws made by legislatures), administrative rules, and case law (court decisions). Laws are divided into civil law (disputes between people) and criminal law (crimes against society).

Nurse Practice Acts and Scope of Practice

Each state has a Nurse Practice Act that defines what nurses are legally allowed to do. Licensure is the state’s permission for a nurse to practice. Student nurses have limited scope - they can only do procedures under supervision that they’ve been trained for. Professional accountability means nurses are responsible for their own actions.

Delegation is when a superior assigns a task to someone else, but the person delegating remains responsible if something goes wrong.

Standards of Care are universal guidelines developed for all nursing interventions that define the appropriate measures nurses should follow. Professional discipline and continuing education are required to maintain licensure and competence.

Laws Affecting Nursing Practice:

• OSHA - Occupational Safety and Health Administration protects worker safety

• CAPTA - Child Abuse Prevention and Treatment Act requires reporting suspected child abuse

• Discrimination laws - Protect against discrimination based on race, religion, gender, etc.

• Sexual harassment laws - Protect against unwanted sexual behavior

• Good Samaritan Laws - Protect people who help in emergencies

• Patient’s Rights - Include right to privacy, informed consent, quality care

• National Patient Safety Goals - Improve safety in healthcare

The Medical Record is a legal document that documents all patient care and must be accurate and complete.

Protection from Lawsuits

HIPAA (Health Insurance Portability and Accountability Act) protects patient privacy - nurses cannot share patient information without authorization.

Consent is a patient’s informed agreement to treatment after being told about risks and benefits. A release is a legal document signing away certain rights.

Advance Directives are documents where patients specify what medical treatment they want if they become unable to communicate.

Negligence is failure to provide care that a reasonable nurse would provide. Malpractice is negligence by a professional and requires four elements to prove:

1. Duty (nurse had a responsibility to the patient)

2. Breach of duty (nurse failed to meet that responsibility)

3. Causation (the breach caused harm)

4. Damages (patient suffered injury/loss)

Common Legal Issues:

• Assault - threatening to touch someone without permission

• Battery - actually touching someone without permission

• Defamation - making false statements that damage someone’s reputation

• Invasion of privacy - violating patient confidentiality

• False imprisonment - unlawfully restricting someone’s freedom

• Protective devices - restraints must be used properly and documented

Decreasing Legal Risk

Nurses can protect themselves by:

• Maintaining nursing competence through continuing education

• Filing incident/occurrence reports when errors happen

• Carrying liability insurance

• Following standards of care

• Communicating clearly with patients

• Documenting thoroughly

Ethics in Nursing

Ethics deals with right and wrong behavior. Codes of Ethics are professional standards guiding ethical conduct. Ethical committees help resolve difficult decisions. Ethical dilemmas occur when two values conflict (like patient privacy vs. patient safety).

Chapter 4: Critical Thinking & The Nursing Process

The nursing process is a systematic, organized approach to patient care consisting of five interconnected steps:

1. Assessment - The nurse collects data about the patient

2. Nursing Diagnosis - The nurse identifies patient problems based on the data

3. Planning - The nurse sets goals and plans interventions

4. Implementation - The nurse carries out the planned care

5. Evaluation - The nurse determines if the goals were met

Critical thinking is essential throughout this process. It’s the disciplined ability to think carefully, analyze information, solve problems, and make good decisions. Nurses use the scientific method (observation, hypothesis, testing, conclusion) to approach problems rather than relying on trial and error or intuition alone.

Nurses must also practice priority setting - deciding which tasks to do first based on urgency and importance, and organizing their workload efficiently throughout the day.

Chapter 5: Assessment, Data Analysis & Planning

Assessment is the first and foundational step. Nurses collect data using three approaches:

• Functional health patterns - how the patient functions daily

• Focused assessment - examining one specific problem

• Basic needs assessment - using Maslow’s hierarchy of needs

Data is collected through three methods:

1. The Interview - A structured conversation with three stages:

• Opening (building rapport/trust)

• Body (asking necessary questions)

• Closing (summarizing information)

2. Medical Record Review - Checking charts for face sheet, physician’s orders, nurses’ notes, medications, lab results, surgery reports, and assessments

3. Physical Assessment - A systematic head-to-toe examination including vital signs, level of consciousness, appearance, and checking all body systems

After collecting data, the nurse performs analysis - sorting information, grouping related data together, identifying missing information, and making inferences about patient problems.

A nursing diagnosis statement identifies the patient’s actual or potential health problem and has THREE required components:

• Problem - what’s wrong

• Related/Etiologic factors - what’s causing it

• Defining characteristics - the signs and symptoms present

Problems are then prioritized using Maslow’s hierarchy (physiological needs first, then safety, love/belonging, esteem, self-actualization).

During planning, the nurse establishes expected outcomes - specific, measurable goals for what should be achieved - and nursing interventions - the specific actions the nurse will take to help the patient reach those goals.

Chapter 6: Implementation & Evaluation

Implementation is when the nurse actually carries out the planned care. Before implementing any intervention, the nurse must consider:

• Why is this intervention needed?

• What’s the rationale/reason?

• What’s the standard way to do it?

• What should the expected outcome be?

• What could potentially go wrong?

There are three types of nursing actions:

• Independent actions - done without a physician’s order (teaching, patient hygiene)

• Dependent actions - require a physician’s order (giving medications)

• Interdependent actions - collaborative work with the healthcare team

Some facilities use interdisciplinary care plans or clinical pathways where the whole healthcare team works together on one standardized plan.

Documentation is critical - all interventions must be recorded in the patient’s chart. The saying goes: “If it’s not documented, it wasn’t done.”

Evaluation is the final step where the nurse determines whether the expected outcomes were achieved by comparing actual results to the goals that were set.

Based on evaluation results:

• If outcomes ARE met - the problem is resolved, documented as met, and removed from the care plan

• If outcomes are NOT met - the care plan must be revised and adjusted

This creates a continuous cycle - evaluation leads back to reassessment, and the process repeats as the patient’s needs change.

Quality improvement is an ongoing process where healthcare organizations work to enhance safety and quality of care through evaluation and systematic changes.
