Foundations of nursing practice

Nursing Framework and Analytical Thinking

1. Phases of the Nursing Framework (ADPIE)

The nursing framework is a structured, patient-focused method used in medical environments to promote safe and effective treatment. It includes five fundamental phases, commonly remembered by the acronym ADPIE:

• Observation
  • Explanation: Collecting essential patient details (both subjective and objective data) to recognize medical concerns and individual requirements.
  • Examples of Tasks:
    • Conducting discussions and reviewing medical history
    • Performing physical evaluations (e.g., comprehensive or targeted assessments)
    • Examining laboratory reports, diagnostic tests, and medical documents
• Identification
  • Explanation: Examining gathered information to recognize key health concerns and establish nursing assessments. (It is important to note that while LPN/LVNs usually assist in data collection, RNs may officially determine nursing assessments based on state guidelines.)
  • Examples of Tasks:
    • Organizing related findings (e.g., high fever, infected wound discharge, chills)
    • Recognizing patterns that align with established NANDA-I nursing assessments
    • Differentiating existing conditions from potential or developing concerns
• Strategy Development
  • Explanation: Establishing realistic, achievable objectives and selecting effective measures to address recognized health concerns.
  • Examples of Tasks:
    • Arranging care priorities using structured models (e.g., Maslow’s hierarchy, ABCs)
    • Creating CLEAR objectives (Concrete, Logical, Effective, Attainable, Result-driven)
    • Coordinating with the healthcare team to optimize resources (e.g., physical rehabilitation, nutritional support)
• Execution Phase
  • Explanation: Carrying out the planned approaches to assist patients in meeting their health objectives.
  • Examples of Tasks:
    • Administering medications and treatments responsibly
    • Educating individuals on positive lifestyle adjustments (e.g., smoking cessation, dietary improvements)
    • Observing patient reactions to interventions and keeping accurate records of all actions
• Review and Modification
  • Explanation: Assessing patient progress to determine if intended health goals have been reached and adjusting the care plan as needed.
  • Examples of Tasks:
    • Checking improvements in patient conditions (e.g., lower pain levels, stabilized vital signs)
    • Reassessing objectives and modifying strategies for unresolved or new issues
    • Sharing evaluation results with the broader medical team to enhance patient care

Overview of the Nursing Process

Step	Primary Goal	Nurse’s Responsibilities	Illustrative Example
Observation	Collect detailed patient information	Assess, interview, review medical records, and examine the patient	Record pain intensity, check vital signs, and inspect wounds
Identification	Determine key issues or health concerns	Analyze collected data, formulate nursing judgments (under RN supervision)	Diagnose “Postoperative Pain related to surgical incision” or “Potential Infection Risk due to open wound”
Strategy Development	Set objectives and choose interventions	Create a structured care plan using clinical reasoning	“Patient will report pain below 3/10 within 24 hours” and plan for pain relief
Execution	Implement the established care plan	Carry out interventions, assign responsibilities, document procedures	Administer prescribed pain medication, educate the patient on proper wound care
Review & Adjustment	Evaluate progress and modify approach as needed	Assess patient outcomes and revise treatment plan accordingly	Pain level reduced to 2/10; reassess wound healing and update care plan if necessary

2. Frameworks for Prioritizing Patient Care (e.g., Maslow’s Hierarchy, ABCs)

In nursing, being able to effectively prioritize patient needs is crucial for delivering timely, life-saving care. Two widely used frameworks guide decision-making about what requires immediate attention and what can be addressed later:

• Maslow’s Hierarchy of Needs
  • Focuses on addressing basic physiological needs (e.g., breathing, nourishment, hydration, waste elimination) before moving on to safety, social connections, esteem, and self-fulfillment.
  • Use Case: If a patient faces multiple concerns—such as anxiety from a new diagnosis and low oxygen levels—ensuring physiological stability (oxygenation) takes priority.
• ABCs (Airway, Breathing, Circulation)
  • Focuses on ensuring a clear airway (A), promoting proper breathing (B), and maintaining stable circulation (C).
  • Use Case: In a scenario where one patient is choking (airway issue) and another has a pain level of 6/10, the choking patient must be prioritized due to the life-threatening nature of airway compromise.
    Additional Tip: Some frameworks extend the ABCs to include D (Disability) and E (Exposure), especially in trauma cases, to ensure thorough assessment of injuries or potential threats.

3. Clinical Judgment and Decision-Making

Clinical judgment is the process of combining critical thinking with clinical expertise to determine the best action for each patient. It requires nurses to stay alert, analytical, and flexible as patient conditions evolve.

• Critical Thinking
  • Definition: A purposeful, reflective approach to interpreting data, exploring options, and making informed decisions.
  • Application: Used throughout nursing, such as when administering medication (“Is this the correct dose for this patient?”) or when providing patient education (“What teaching method would be most effective for this patient?”).
• Core Elements of Decision-Making
  • Identifying Key Indicators: Recognizing important changes or anomalies (e.g., a sharp drop in blood pressure).
  • Analyzing Information: Consulting research or guidelines (e.g., facility protocols for managing hypotension).
  • Selecting an Action: Choosing interventions based on evidence and patient preferences (e.g., administering fluids, adjusting medications).
  • Evaluating Results: Determining whether the intervention improved the patient’s condition (e.g., stabilized blood pressure). If not, further actions may be necessary.
• Integrating Clinical Judgment with Prioritization
  • Always ask: “Which action is the most critical right now?”
  • For a patient with chest pain, the decision to administer oxygen or nitroglycerin first may depend on their breathing rate, oxygen levels, and current protocols. Each piece of information helps the nurse identify the immediate action with the greatest impact on patient safety and well-being.

Professional and Legal Considerations

4. Scope of Practice for LPN/ADN

Nurses, based on their level of education and licensure, are regulated by the Nurse Practice Act in their state, which outlines the duties they are permitted to perform. While the specifics can differ by state, there are general distinctions between the Licensed Practical Nurse (LPN) and the Associate Degree Nurse (ADN, or RN in some regions).

• LPN (Licensed Practical Nurse)
  • Provides fundamental, direct patient care under the supervision of an RN or physician.
  • Common responsibilities include administering medications (with some limitations), taking vital signs, assisting with personal care, performing wound care, and reporting any changes in the patient’s condition.
  • Typically assists with data collection and contributes to care planning, but may not independently make nursing diagnoses in certain states.
• ADN (Associate Degree Nurse/RN)
  • Takes responsibility for assessing, diagnosing (nursing diagnoses), planning, implementing, and evaluating patient care, utilizing the full nursing process.
  • Can initiate and manage complex interventions, create detailed care plans, and delegate tasks to LPNs or unlicensed assistive personnel (UAPs).
  • Holds wider-ranging responsibilities, including patient education, leadership roles, case management, and involvement in policy-making.

Comparison Between LPN and ADN Scope

Aspect	LPN (Licensed Practical Nurse)	ADN (Associate Degree Nurse/RN)
Level of Education	Typically a 1-year practical nursing course	A 2-year nursing program at the college level
Core Focus	Direct patient care, concentrating on technical tasks and bedside duties	Holistic nursing care, utilizing the full nursing process
Supervision Requirements	Operates under the direction of an RN or MD (dependent on state rules)	Practices independently, adhering to the state’s Nurse Practice Act, and supervises LPNs/UAPs in many states
Care Plan Contribution	Gathers assessment information and follows set care plans	Creates, adjusts, and evaluates care plans
Role in Leadership	Limited in leadership and delegation responsibilities	Engages in greater leadership roles, including managing healthcare teams
Medication Management	Administers medications with specific limitations (e.g., some IV medications)	Has broader authority over medication administration, including IV push (depending on the state and facility)

5. Ethical Standards and Patient Privacy (HIPAA)

Ethical conduct and maintaining confidentiality are fundamental aspects of professional nursing. These principles shape how nurses interact with patients, their families, and the healthcare system as a whole.

A. Core Ethical Principles

1. Autonomy

• Supports a patient’s freedom to make well-informed choices regarding their own care.
• Nurses are expected to honor these decisions, even when they personally disagree, provided the patient is capable and properly informed.

2. Beneficence

• Focuses on promoting the well-being of the patient.
• This can involve timely medical interventions, ensuring patient comfort, or advocating for appropriate treatments.

3. Nonmaleficence

• Refers to the duty to avoid causing harm.
• Nurses apply this by taking precautions like confirming allergies and double-checking medication orders.

4. Justice

• Involves providing fair and equal care to all individuals.
• Nurses are expected to treat patients impartially, without bias related to factors such as age, race, gender, or financial status.

B. Patient Privacy and Information Security (HIPAA)

1. Overview of HIPAA (Health Insurance Portability and Accountability Act)

• Designed to protect the confidentiality of patient health information (PHI) and promote privacy standards in healthcare.
• Restricts the disclosure of patient data to only those who are authorized and directly involved in the individual’s treatment.

2. Real-World Practices

• Maintain the security of medical records, digital files, and any personal devices that store patient information.
• Refrain from discussing patient cases in shared or public spaces like hallways, cafeterias, or elevators.
• Access medical records solely for patients you are actively caring for.

3. Consequences of Breaches

• Violations may lead to legal repercussions for the individual or institution involved.
• Penalties can include financial fines, loss of professional licensure, or termination from employment.

6. Patient Participation and Decision-Making Rights

Patients are entitled to actively engage in decisions about their care. This includes understanding proposed treatments and exercising control over what is done to their bodies, primarily through informed consent and respect for personal rights.

A. Understanding Informed Consent

• What It Means: A collaborative communication process where the patient, or an authorized representative, agrees to a procedure or treatment after receiving a full explanation of its purpose, benefits, potential risks, and other available options.
• Role of the Nurse:
  • Confirm that the patient genuinely understands the details explained by the provider.
  • Make sure the consent is given freely—without pressure—and the patient is alert and capable of making an informed choice.
  • Record any patient concerns and questions, and encourage follow-up explanation if confusion or hesitation remains.

B. Respecting Patients’ Legal and Ethical Rights

• Right to Self-Determination: Patients have the freedom to decline treatments, even if doing so may adversely affect their health.
• Privacy Assurance: Patient health information must be protected in accordance with privacy laws.
• Right to Discreet Care: All healthcare interactions should remain confidential unless disclosure is legally required.
• Right to Clear Communication: Patients deserve clear, understandable information and the opportunity to ask questions to support informed decisions.

7. Legal Responsibilities in Nursing Practice

Nurses are legally required to act in certain situations beyond clinical care. Understanding these obligations ensures patient safety and supports ethical nursing practice.

A. Reporting Duties

1. Scenarios That Require Reporting:
   • Suspected Child Abuse or Neglect: Nurses must alert the proper authorities when abuse is suspected.
   • Elder Mistreatment: Includes reporting of neglect, emotional abuse, physical harm, or financial manipulation.
   • Intimate Partner Violence: Legal duty to report varies depending on local laws, but may be mandatory in some cases.
   • Reportable Diseases: Specific contagious illnesses must be communicated to public health officials to support broader community protection.
2. Why It Matters:
   • Shields vulnerable individuals from further harm.
   • Supports public health responses to prevent outbreaks.
   • Reinforces the nurse’s ethical responsibility to promote patient safety and well-being.

B. Advance Healthcare Planning

1. What Are Advance Directives?
   • Legally recognized documents that describe a person’s medical care preferences in case they lose the ability to decide for themselves. Common forms include Living Wills and Healthcare Proxies.
2. Types of Advance Directives:
   • Living Will: States specific treatments a patient does or doesn’t want in critical or end-of-life situations (e.g., resuscitation, feeding tubes).
   • Healthcare Proxy (Durable Power of Attorney): Appoints someone trusted to make care decisions on the patient’s behalf if they are incapacitated.
3. Nurse’s Involvement:
   • Educate patients on their options and rights regarding advance directives.
   • Ensure these documents are included in the medical record and honored during care planning.
   • Offer compassionate support to families and patients while discussing sensitive topics about future care preferences.

Therapeutic Communication and Cultural Sensitivity

8. Building Meaningful Nurse–Patient Interactions

Strong communication skills are essential in nursing, laying the groundwork for trust, accurate assessment, and cooperation in care. The way nurses communicate directly impacts patient comfort, understanding, and participation in treatment decisions.

A. Elements of Effective Communication

1. Spoken and Written Language

• Definition: The deliberate use of words—whether spoken or written—to share thoughts, information, and instructions.
• Key Factors to Keep in Mind:
  • Tone and Clarity: Use simple, direct language and avoid overly technical terminology.
  • Speaking Pace: Adjust your speed to suit the patient’s ability to follow.
  • Volume: Be mindful of hearing ability and cultural differences that may affect perceptions of loudness.

2. Nonverbal Signals

• Definition: Communication that happens without words—through body posture, facial expression, gestures, and proximity.
• Cultural and Contextual Awareness:
  • Eye Contact: May indicate attentiveness and respect in some cultures but could be uncomfortable or inappropriate in others.
  • Posture and Gestures: Leaning in can express engagement; folded arms might suggest discomfort or disapproval.
  • Facial Expressions: A warm expression can reassure patients, but it must match the message being delivered to avoid confusion or mistrust.

3. Engaged and Respectful Listening

• Key Techniques:
  • Use culturally appropriate eye contact.
  • Show attentiveness through small verbal prompts or nods.
  • Reflect or restate the patient’s thoughts to demonstrate understanding, such as: “It sounds like you’re nervous about the upcoming procedure.”
• Why It Matters: Active listening not only confirms understanding but also makes patients feel heard, valued, and respected.

B. Therapeutic vs. Nontherapeutic Communication Techniques

Technique	Description	Example
Therapeutic	Promotes open dialogue, strengthens trust, and fosters mutual understanding.	– Asking open-ended questions: “Could you tell me more about your feelings?” – Offering support: “I’m available to listen to any concerns you have.”
Nontherapeutic	Creates obstacles in communication, which may cause the patient to withdraw or feel judged.	– Providing unwarranted reassurance: “It will all work out, don’t worry.” – Interrupting or completing the patient’s sentences.

C. Tips for Enhancing Communication Effectiveness

• Simplify Language: Use straightforward, non-technical language to ensure that patients fully understand what is being communicated.
• Clarify and Confirm: Follow up with questions to ensure the patient’s message is understood accurately, such as: “When you say you’re having ‘trouble breathing,’ do you feel shortness of breath or tightness?”
• Honor Silence: Allow for quiet moments, which can give patients time to collect their thoughts or process difficult emotions.
• Ensure Privacy: Always discuss sensitive topics in a private setting to promote openness and protect confidentiality.

9. Patient-Centered Care and Embracing Cultural Differences

Patient-centered care emphasizes honoring each patient’s individual experiences, values, and cultural perspectives. Recognizing and respecting cultural diversity is key to building trust and providing care that meets patients’ needs effectively.

A. Understanding Cultural Competence

1. Definition:
   Cultural competence refers to the ability to provide healthcare that acknowledges and integrates the diverse cultural beliefs, practices, and needs of patients.
2. Why It’s Important:
   • Facilitates clear communication, helping to prevent misunderstandings.
   • Promotes adherence to treatment plans by incorporating culturally significant health practices (such as diet or alternative treatments).
   • Encourages mutual respect, empowering patients to actively engage in their healthcare.

B. Assessing Cultural Needs

1. Cultural Assessment Areas:
   • Language and Communication: Identify if an interpreter is needed for effective communication.
   • Dietary Preferences: Ask about any cultural or religious dietary restrictions.
   • Beliefs and Values: Understand the patient’s views on health, illness, and end-of-life care.
   • Family and Social Structure: Recognize key decision-makers within the patient’s family or community.
2. Adapting Care:
   • Religious Practices: Accommodate religious observances, such as prayer or fasting, when possible.
   • Traditional Medicine: Respect the use of holistic or alternative treatments, integrating them safely into the care plan.
   • Gender Sensitivity: Some patients may prefer caregivers of the same gender for sensitive procedures.

C. Examples of Culturally Competent Interventions:

• Professional Interpreters: Ensures precise communication, reducing the risk of misunderstandings, unlike relying on family members who may inadvertently misinterpret.
• Dietary Adjustments: Providing culturally appropriate meal options, such as vegetarian or halal meals.
• Nonverbal Respect: Adjusting body language, including eye contact and personal space, according to the patient’s cultural norms.

10. Effective Patient Education Techniques

Patient education is a vital part of nursing care. By educating patients, nurses empower them to make informed decisions, follow treatment plans, and take control of their own health.

A. Principles of Adult Learning

• Relevance: Adults need to see how the information directly benefits them, such as explaining how blood glucose monitoring contributes to better health.
• Readiness: Effective teaching occurs when patients are emotionally and mentally prepared to learn, such as teaching wound care when the patient is comfortable and pain-free.
• Leveraging Past Experience: Build on what patients already know, linking new information to familiar routines or previous experiences.

B. Teaching Methods and Approaches

1. Verbal Instruction:
   • Provide clear and concise explanations.
   • Use simple terms and relatable analogies to clarify complex concepts.
2. Printed or Digital Resources:
   • Offer written materials at an easy-to-read level (around 5th–6th grade).
   • Direct patients to trusted online resources for further learning, such as MedlinePlus.
3. Demonstration and Return Demonstration:
   • Demonstrate a skill first, then have the patient repeat it to confirm understanding.
   • Helps the patient build confidence before they leave the healthcare setting.
4. Teach-Back Technique:
   • Ask the patient to explain key information in their own words to confirm comprehension.
   • Example: “Can you explain how you would change your dressing when you’re home?”

C. Evaluating Learning Progress:

• Assess Knowledge and Skills: Ask open-ended questions or have the patient demonstrate what they’ve learned.
• Encourage Questions: Prompt patients to voice any confusion or uncertainties, as they might not bring them up on their own.
• Document the Learning: Record what was taught, the patient’s responses, and any areas that require further clarification.

Infection Control and Safety

11. Standard and Transmission-Based Precautions

Infection prevention starts with implementing the proper precautions to minimize the risk of transmitting pathogens. Nurses must determine the appropriate level of protection based on the patient’s condition and diagnostic details.

A. Standard Precautions

1. Definition:
   Standard Precautions are applied to all patient interactions, assuming all bodily fluids and substances may carry infectious agents. These represent the minimum required measures for infection prevention.
2. Essential Practices:
   • Hand Hygiene: Perform before and after any patient contact.
   • Glove Use: Wear gloves when handling bodily fluids, non-intact skin, or mucous membranes.
   • Face Protection (Mask/Face Shield): Use when there is a risk of exposure to splashes or sprays (e.g., during suctioning).
   • Gown: Wear a gown when anticipating contact with bodily fluids to protect clothing and skin.
3. Purpose:
   • Minimizes the risk of transferring pathogens between patients or from patients to healthcare providers.
   • Serves as the foundational level of infection control, with additional transmission-based precautions added as needed.

B. Transmission-Based Precautions

1. Contact Precautions
   • When to Apply: For infections spread through direct contact (e.g., MRSA, VRE, C. difficile).
   • Personal Protective Equipment (PPE): Gloves and gown.
   • Room Assignment: Place the patient in a private room or group with others infected by the same pathogen.
2. Droplet Precautions
   • When to Apply: For infections transmitted by large respiratory droplets (e.g., influenza, pertussis, meningococcal disease).
   • PPE: Wear a surgical mask within 3 feet of the patient.
   • Room Assignment: Ideally in a private room; if unavailable, maintain at least 3 feet of distance and close curtains.
3. Airborne Precautions
   • When to Apply: For infections that spread through small airborne particles (e.g., tuberculosis, measles, varicella).
   • PPE: N95 respirator mask (or a higher-level mask).
   • Room Assignment: Negative-pressure isolation room with the door always closed.
4. Transmission-Based Precautions at a Glance

Precaution Type	Common Infections	Required PPE	Environmental Requirements
Contact	MRSA, VRE, C. difficile	Gloves, gown	Private room or group with patients carrying the same infection
Droplet	Influenza, Pertussis, Mumps	Surgical mask (within 3 feet)	Preferably a private room; mask required for close proximity
Airborne	Tuberculosis, Measles, Varicella	N95 respirator mask	Negative-pressure isolation room; door must remain closed

12. Infection Prevention, Aseptic Practices, and Hand Hygiene

Understanding the mechanisms of infection transmission is essential for effective infection control. By implementing aseptic techniques and maintaining proper hand hygiene, healthcare providers can prevent the spread of infections at various stages.

A. Infection Transmission Process

1. Key Elements
   • Infectious Agent: (e.g., bacteria, viruses)
   • Reservoir: (e.g., human body, contaminated surfaces)
   • Portal of Exit: (e.g., respiratory droplets, bodily fluids)
   • Mode of Transmission: (e.g., droplets, contact, airborne)
   • Portal of Entry: (e.g., mucous membranes, skin abrasions)
   • Susceptible Host: (e.g., patients with weakened immunity, the elderly)
2. Interrupting the Chain of Infection
   • Destroy the Agent: Use disinfectants and sterilization.
   • Eliminate Reservoirs: Regular cleaning and disposing of contaminated materials.
   • Block Exit and Entry Points: Use wound dressings and practice respiratory hygiene.
   • Prevent Transmission: Hand hygiene, PPE use, and proper disposal of sharp objects.

B. Aseptic Practices

1. Medical Asepsis (Clean Technique)
   • Purpose: Minimize the number of pathogens.
   • Examples: Regular handwashing, glove usage, routine cleaning, and proper disposal of contaminated materials.
2. Surgical Asepsis (Sterile Technique)
   • Purpose: Completely remove all microorganisms from an area.
   • Examples: Wearing sterile gloves, using sterilized tools, and maintaining a sterile field during procedures.

C. Hand Hygiene

1. Proper Handwashing Technique
   • Wet hands with warm water, apply soap, and scrub for 20 seconds, focusing on all areas (palms, backs, between fingers, under nails).
   • Rinse thoroughly and dry using a clean towel or air dryer.
   • Use a paper towel to turn off the faucet, if possible.
2. Alcohol-Based Hand Sanitizers
   • Suitable when hands are not visibly dirty.
   • Rub thoroughly, covering all hand surfaces until dry.
3. Critical Times for Hand Hygiene
   • Before and after patient interactions.
   • Before and after procedures.
   • After touching bodily fluids or contaminated surfaces.
   • After removing gloves.

13. Patient Handling and Fall Risk Reduction

Ensuring both patient and staff safety extends beyond infection prevention. Proper lifting techniques and fall prevention strategies are essential components of everyday nursing care.

A. Safe Patient Handling

• Body Mechanics Guidelines
  • Maintain a broad base of support by positioning your feet shoulder-width apart.
  • Bend at the knees rather than the waist when lifting or lowering.
  • Keep your spine aligned and avoid twisting your body.
  • Hold the load close to your body to better support your center of gravity.
  • For heavy lifting, seek assistance or use mechanical aids.
• Assistive Devices
  • Gait Belts: Provide support for patients who need minimal help during transfers or while walking.
  • Mechanical Lifts (e.g., Hoyer lifts): Essential for safely moving patients with limited mobility, such as those who are bariatric.
  • Slide Boards: Minimize friction-related injuries when transferring patients laterally.

B. Fall Prevention

• Identifying Common Fall Risk Factors
  • Previous falls, age-related issues, mobility challenges, side effects from medications (e.g., sedatives, antihypertensives), and cognitive impairments increase the likelihood of falls.
• Risk Assessment Tools
  • Utilize tools like the Morse Fall Scale to assess the risk level of patients.
• Fall Prevention Methods
  • Ensure the call light is always within easy reach, and instruct the patient on how to use it.
  • Keep the bed in the lowest position and lock the wheels to prevent accidental movement.
  • Provide non-slip footwear and maintain proper lighting in the room.
  • Consider using bed or chair alarms for patients identified as high-risk.
  • Keep hallways and walkways clear of obstacles, such as IV lines and cords, to reduce tripping hazards.

14. Emergency Response: Fire, Disaster, and Critical Situations

Nurses are often on the frontlines during emergencies, whether it’s a fire, natural catastrophe, or large-scale incident. Being prepared and following established guidelines is essential for ensuring safety and minimizing harm.

A. Fire Response Procedures

1. R.A.C.E. Guidelines:
   • R – Remove individuals from immediate danger.
   • A – Alert the fire response team or activate the nearest alarm.
   • C – Contain the fire by shutting doors and windows to slow its spread.
   • E – Extinguish a manageable blaze using the proper extinguisher, or Evacuate if the situation is uncontrollable.
2. P.A.S.S. Method for Extinguisher Use:
   • P – Pull the safety pin.
   • A – Aim the nozzle at the fire’s base.
   • S – Squeeze the handle to release the extinguishing agent.
   • S – Sweep in a back-and-forth motion across the flames.

B. Disaster Readiness

1. Classifying Disasters:
   • Natural Events: Earthquakes, floods, hurricanes.
   • Human-Caused Incidents: Toxic exposures, violence, or infrastructure damage.
   • Public Health Emergencies: Epidemics or widespread disease outbreaks.
2. Preparedness Measures:
   • Healthcare facilities implement a comprehensive response plan addressing all possible hazards. These include clear evacuation routes, assigned staff duties, and designated triage zones.
   • Nurses must understand institutional emergency codes (e.g., Code Red for fire, Code Orange for chemical hazards) and triage models like START (Simple Triage and Rapid Treatment).
3. Mass Casualty Sorting System:
   • Color-coded triage tags help prioritize care based on urgency and survivability:
     • Red (Immediate): Critical injuries needing urgent care.
     • Yellow (Delayed): Injuries that can tolerate short delays.
     • Green (Minimal): Minor injuries; can assist others or walk.
     • Black (Expectant): Little chance of survival; provide comfort measures.

C. Critical Emergency Responses

• Code Blue: Activated for cardiac or respiratory failure—begin life-saving interventions and bring emergency equipment.
• Code Grey: Signals a potential security threat, such as an aggressive or violent individual—respond according to facility protocol.
• Rapid Response Team (RRT): Called when a patient begins showing signs of clinical decline, enabling early intervention before full deterioration.

V. Essential Clinical Skills and Recordkeeping

15. Monitoring Vital Signs (Expected Values and Clinical Insight)

Vital signs serve as a quick snapshot of a patient’s current health. Nurses must be able to identify standard values, detect abnormalities, and assess what those deviations may imply.

A. Core Vital Sign Measurements

1. Body Temperature

• Usual Range: 97.5°F to 99.5°F (36.4°C to 37.5°C) in adults
• Methods of Measurement: Oral, rectal, axillary, tympanic (ear), or temporal (forehead)
• Clinical Significance:
  • Higher than normal (>99.5°F/37.5°C): May suggest a fever from infection or an inflammatory process.
  • Lower than normal (<97.5°F/36.4°C): Could signal hypothermia or metabolic/endocrine irregularities.

2. Heart Rate (Pulse)

• Usual Range: 60 to 100 beats per minute (bpm)
• Assessment Sites: Commonly checked at radial or apical pulse points; also includes carotid, femoral, brachial, popliteal, dorsalis pedis, and posterior tibial arteries
• Clinical Significance:
  • Tachycardia (>100 bpm): Could be linked to fever, dehydration, anxiety, or heart issues.
  • Bradycardia (<60 bpm): May be a normal finding in physically fit individuals or a sign of conduction abnormalities.

3. Respiratory Rate

• Usual Range: 12 to 20 breaths per minute
• Key Observations: Assess rate, rhythm, depth, and ease of breathing
• Clinical Significance:
  • Increased rate (>20/min): May point to pain, anxiety, or breathing difficulties.
  • Decreased rate (<12/min): Could stem from sedation, neurological dysfunction, or respiratory fatigue.

4. Blood Pressure (BP)

• Typical Value: Around 120/80 mmHg in healthy adults
• Clinical Significance:
  • Elevated readings (≥130/80 mmHg): May be associated with chronic conditions or poor lifestyle habits.
  • Low readings (systolic <90 mmHg): Could result from dehydration, blood loss, or shock.

5. Oxygen Saturation (SpO₂)

• Expected Range: 95% to 100% breathing room air
• Clinical Significance:
  • Below 90%: May signal inadequate oxygen levels and require urgent care.
  • Chronic lung conditions (e.g., COPD): May have acceptable baselines between 88–92%.

B. Best Practices for Accurate Vital Sign Monitoring

• Correct Equipment Usage: Choose the right BP cuff size to prevent skewed results.
• Reliable Pulse Assessment: Count for 30 seconds and double the result if the rhythm is steady; count for a full minute if irregular.
• Track Patterns: A single abnormal reading may not reflect a true issue—look at trends over time to evaluate a patient’s progress or decline.

Vital Sign	Expected Values	Clinical Notes
Body Temperature	97.5°F–99.5°F (36.4°C–37.5°C)	Oral is typical; rectal may read about 1°F higher
Heart Rate (Pulse)	60–100 beats per minute	If pulse is irregular, assess apical pulse for a full 60 seconds
Respiratory Rate	12–20 breaths per minute	Evaluate rhythm, depth, and whether breathing is labored or easy
Blood Pressure	Approximately 120/80 mmHg	Measure in both arms if needed; assess for orthostatic changes if symptomatic

16. Accurate and Ethical Charting (Electronic and Manual Records)

Precise documentation is not just about recording facts—it ensures continuity of care, supports clinical decisions, and holds legal value. Nurses must document care clearly and consistently, whether electronically or on paper.

A. Foundational Documentation Practices

• Objective and Clear: Focus on observable facts and direct quotes. Example: Document “Patient reports, ‘I feel dizzy,’” instead of implying emotional states.
• Detailed and Honest: Include exact times, doses, and findings. Leaving out details could lead to miscommunication or errors in care.
• Prompt Entries: Log information as soon after an event as possible to avoid memory gaps and legal issues.
• Legal Awareness: Never chart tasks not completed. To correct paper errors, strike through with one line and annotate with date, time, and initials as per protocol.

B. Comparing Charting Systems

Type	Benefits	Drawbacks
Electronic Records (EHR)	Easily read and shared; includes built-in alerts and auto-calculations	Needs login access, computer literacy, and may crash during updates
Paper Records	Easy for quick notes; no device needed	Risk of poor handwriting, missing data, or physical misplacement

17. Monitoring Intake and Output (I&O)

Fluid balance monitoring helps clinicians detect early warning signs in patients receiving IV therapy, with cardiac or renal conditions, or under diuretic treatment.

A. Fluid Intake

• Oral Fluids: Includes drinks, broths, jello, and partially melted ice chips (recorded at 50% volume).
• Tube Feeding: Log all administered enteral formulas.
• IV Administration: Document flow rates for infusions and bolus doses.

B. Fluid Output

• Urine: Measured with urinals, catheters, or collection containers.
• Stool: Note frequency and quantity, particularly if liquid or unusual.
• Other Output: Track measurable losses from vomit, drains, wound exudate, or chest tubes.

C. Why I&O Matters

• Detecting Fluid Imbalance: Higher output than intake may indicate dehydration, while the reverse could signal retention or organ failure.
• Renal Monitoring: Reduced urine flow may reflect worsening kidney function.
• Effectiveness of Interventions: For instance, diuretics should yield noticeable urine output if working as expected.

18. Personal Hygiene and Daily Care

Supporting hygiene enhances not only physical health but also a patient’s sense of well-being and dignity. Consistent care prevents infections and supports recovery.

A. Types of Personal Care

1. Bathing Options
   • In-Bed Cleansing: For immobile patients; requires caregiver assistance.
   • Shower or Bath: For those who can ambulate and tolerate standing.
2. Mouth Care
