Week 1 Lecture Notes: Conceptual Foundation

1. Understanding Three Essential Cognitive Processes

• Critical Thinking = “The Foundation”

  • How you think
    • Question Everything: Encourages skepticism and in-depth inquiry.
    • Analyze Information: Assess validity and relevance of the information.
    • Don't Just Accept Things — Ask Why: Provoke deeper understanding of situations.
    • Use Evidence: Base conclusions on factual and empirical evidence.
      • Example: "Why is this patient’s blood pressure low?"

• Clinical Reasoning = “The Process”

  • How you work through a situation
    • Collect Patient Information: Gather data such as vitals, patient history, and symptoms.
    • Understand What’s Going On: Interpret the data collected to assess the patient's condition.
    • Plan What to Do: Formulate an intervention strategy based on findings.
    • Evaluate if it Worked: Assess the outcomes of interventions.
      • Example: "BP is low → maybe dehydration → give fluids → reassess BP"

• Clinical Judgement = “The Outcome”

  • The decision you make
    • What Action Will You Take?: Refers to the tactical responses in patient care.
    • What is the Priority?: Determine the most urgent needs of the patient.
      • Example: "This patient is unstable → needs urgent fluids and review"

2. Practical Application in Nursing

• Ask Yourself:
  • What is Happening? (Critical Thinking)
  • Why is it Happening? (Clinical Reasoning)
  • What Should I Do Now? (Clinical Judgement)
• Example in Nursing:
  • Patient is Short of Breath:
    • Critical Thinking:
      • "Is this due to fluid overload, infection, or anxiety?"
    • Clinical Reasoning:
      • Check vitals, oxygen levels, listen to lungs.
    • Clinical Judgement:
      • Give oxygen, sit patient upright, escalate if needed.

3. Prioritizing Patient Care in Nursing

• Prioritisation in Nursing: Deciding which patient or task needs attention first to ensure patient safety and effective care.

• Structured Frameworks: Nurses utilize frameworks to make decisions, especially when managing multiple patients.

• 1. ABC Approach (Airway, Breathing, Circulation)

  • Purpose: Quickly identify and treat life-threatening problems in emergency situations.
  • Principle: Assess and manage in this order:
    1. Airway (A)
       • Is the airway open and clear?
       • Look for obstructions (vomit, tongue, swelling).
       • Interventions: reposition (head tilt–chin lift), suction, airway adjunct.
    2. Breathing (B)
       • Is the patient breathing effectively?
       • Assess rate, depth, effort, oxygen saturation.
       • Interventions: oxygen, repositioning, ventilation support.
    3. Circulation (C)
       • Is blood circulating properly?
       • Check pulse, blood pressure, capillary refill, skin color.
       • Interventions: IV fluids, control bleeding, medications.

4. Clinical Scenario: Emergency Assessment

• Patient: 68-year-old male found unresponsive after a fall.

• Airway Assessment:

  • Check for obstruction, employ head tilt-chin lift, jaw thrust if cervical injury suspected.
  • Airway clear but requires positioning.

• Breathing Assessment:

  • Look, listen, feel for breathing; count rate; assess depth and symmetry.
  • Finding: Shallow, rapid breathing at 28/min.

• Circulation Assessment:

  • Check pulse, blood pressure, capillary refill, skin color.
  • Finding: Weak pulse, delayed capillary refill.

• Key Rule: You must fix problems in order:

  • No airway → patient will die first.
  • Breathing comes before circulation.

5. Clinical Example

• Unresponsive Patient After a Fall:
  • Airway: Needs repositioning → first priority.
  • Breathing: Rapid, shallow → give oxygen.
  • Circulation: Weak pulse → urgent review.
  • ✔ This patient is high priority because ABCs are compromised.

6. Maslow’s Hierarchy of Needs (Holistic Care)

• Purpose: Used for overall care planning, ensuring both physical and psychological needs are addressed.

• Hierarchy (Lowest to Highest Priority):

  1. Physiological Needs:
     • Airway, breathing, circulation, food, fluids, elimination.
  2. Safety Needs:
     • Prevent falls, medication safety, infection control.
  3. Love and Belonging:
     • Family, emotional support.
  4. Esteem:
     • Respect, independence, dignity.
  5. Self-Actualisation:
     • Education, goals, quality of life.

• Key Rule: Always meet lower-level needs first before progressing to higher ones.

• Clinical Example (Post-operative Patient):

  • Immediate (0–24 hrs): Physiological: monitor vitals, pain, fluids.
    • Safety: prevent complications, falls.
    • Recovery (24–72 hrs): Continue physiological care, encourage family support.
    • Pre-Discharge: Promote independence (esteem), provide education (self-actualisation).
  • ✔ Shows progress from survival → recovery → independence.

7. Acuity Rating (Who is Sickest?)

• Purpose: Used in triage settings (e.g., Emergency Department) to prioritise patients based on the urgency of their condition.

• Categories (Australasian Triage Scale):

  • Category 1 – Immediate life-threatening (seen immediately).
  • Category 2 – Imminently life-threatening.
  • Category 3 – Potentially life-threatening.
  • Category 4 – Potentially serious.
  • Category 5 – Less urgent.

• Key Rule: Patients with higher acuity are seen first, regardless of arrival time.

• Clinical Example:

  • Chest pain + altered consciousness → Category 1.

  • Severe asthma attack → Category 2.

  • Wrist fracture → Category 3-4.

  • Fever and earache → Category 5.

    • ✔ This ensures limited resources go to the sickest patients first.

8. C.U.R.E Framework (Task Prioritisation)

• Purpose: Enables effective allocation of resources and optimised patient flow.

  • Supports safe, effective workload management for nurses and helps manage multiple competing demands while ensuring critical patient needs are addressed first.
  • Categories:
    • C – Critical: Immediate life-saving intervention required.
    • U – Urgent: Needs prompt care but not immediately life-threatening.
    • R – Routine: Standard care tasks.
    • E – Extra: Non-urgent tasks that can be delayed but are important.

• Clinical Example (Morning Shift):

  • Post-operative hemorrhage → Critical (drop in BP, bleeding).
  • Fever and pain → Urgent.
  • Morning medications → Routine.
  • Discharge planning → Extra.

• ✔ Tasks should be completed in this order: C → U → R → E.

9. Integrating All Frameworks in Practice

• In real nursing situations, use all frameworks together:

  • Step 1: Use ABC – Is there a life-threatening issue?
  • Step 2: Use Acuity – Who is the sickest patient?
  • Step 3: Use Maslow – What basic needs must be met?
  • Step 4: Use CURE – What task should I do first?

• Example Scenario: You have 4 patients:

  1. Patient with airway obstruction
  2. Patient with chest pain
  3. Patient needing pain medication
  4. Patient awaiting discharge

• Prioritisation:

  • Airway obstruction → ABC + Critical.
  • Chest pain → High acuity (urgent risk).
  • Pain medication → Urgent.
  • Discharge → Extra.

• ✔ Final order: 1 → 2 → 3 → 4.

10. Key Takeaways

• ABC → identifies life-threatening problems.
• Acuity → determines who is most unwell.
• Maslow → ensures basic needs are met first.
• CURE → organises your workload.
• Together, they help you deliver safe, effective, patient-centred care.

11. Acute Patient Deterioration

• What is it?: Acute patient deterioration is when a patient’s condition suddenly worsens.
• Importance: Patient safety depends on nurses being able to:
  • Detect abnormal vital signs.
  • Understand what they mean.
  • Act and escalate care quickly.
• Consequences if Missed:
  • ICU admission, organ failure, death.
• Why is it a big problem?:
  • Happens frequently in hospitals and many cases are preventable.
  • Over 100,000 rapid response calls happen each year in Australia & NZ.
• Main Issue: Failure to recognize and respond early.

12. Six Main Causes of Failure

• 1. Inconsistent Monitoring of Physical Observations

  • The Problem: Vital signs are not measured regularly or accurately.
  • Importance: Vital signs are the first indicator that a patient is deteriorating.

• Key Vital Signs:

  • Respiratory rate
  • Oxygen saturation
  • Heart rate
  • Blood pressure
  • Temperature

• Example: A patient with pneumonia:

  • Respiratory rate increases from 18 to 28.
  • Oxygen saturation drops from 96% to 92%.
  • With Regular Monitoring: Detect changes early, initiate treatment early, patient remains stable.
  • With Poor Monitoring: Changes are missed, patient deteriorates, possible ICU admission.
  • Key Point: If vital signs are not checked, deterioration cannot be detected.

• 2. Not Understanding Changes in Physiological Observations

  • The Problem: Vital signs are looked at individually instead of as a pattern.
  • Importance: Small changes in multiple vital signs can indicate serious deterioration, even if each value seems “normal” on its own.
  • Example: Post-operative patient:
    • Blood pressure drops from 130 to 112.
    • Heart rate increases from 80 to 100.
    • These changes may appear minor, but together they suggest early shock or bleeding.
    • Key Point: Always look at trends and patterns, not single values.

• 3. Lack of Knowledge of Symptoms Indicating Deterioration

  • The Problem: Early signs of deterioration can be subtle and easily missed.
  • Why it Matters: Serious conditions like sepsis often begin with mild symptoms.
  • Example: Early sepsis:
    • Temperature 38.1°C.
    • Heart rate 95.
    • Mild confusion.
  • Each sign alone may seem minor, but together they indicate possible sepsis.
    • Key Point: Multiple small changes can indicate serious illness.

• 4. Lack of Formal Systems to Respond to Deterioration

  • The Problem: No clear guidelines on when and how to escalate care.

  • Importance: Delays in escalation can lead to worsening patient outcomes.

  • Example: Patient with low blood pressure and reduced urine output:

    • With Structured System: Escalation happens quickly, treatment starts early, patient stabilises.
    • Without System: Delays occur, patient deteriorates further.

  • Consequences of Delayed Response:

    • Shock, organ damage, extended hospital stay.
    • Key Point: Early escalation to senior staff or rapid response teams is essential.

• 5. Lack of Skills to Manage Patients Who Are Deteriorating

  • The Problem: Nurses may recognize deterioration but fail to act effectively.

  • Essential Skills:

    • Comprehensive assessment skills.
    • Immediate intervention skills including oxygen therapy and airway management.
    • Team coordination and communication skills during fast-paced situations.

  • Importance: Immediate actions can prevent further decline before specialized help arrives.

  • Example: Patient with acute heart failure:

    • Effective response: Perform rapid assessment, call for help, sit patient upright, administer oxygen, prepare medications.
    • Ineffective response: Only monitor vital signs; wait for help.
    • Key Point: Recognition alone is not enough; immediate intervention is required.

• 6. Failure to Communicate Clinical Concerns, Including During Handover

  • The Problem: Important information is not communicated clearly or completely.
  • Importance: Poor communication can lead to missed deterioration and unsafe care.
    • Example: Handover states: "Patient is a bit restless, vitals mostly stable." But actual observations:
  • Temperature 39°C.
  • Heart rate 120.
  • This significant deterioration was not communicated properly.

• Solution: Use structured communication such as ISBAR:

  • Identify: Who you are and who the patient is.
  • Situation: Describe what’s happening.
  • Background: Provide background information.
  • Assessment: Assess the situation (vital signs).
  • Recommendation: Offer recommendations for care.

• Key Point: Clear and structured communication ensures continuity of safe care.

13. How to Prevent Deterioration

• Follow a systematic approach:
  1. Monitor: Regularly check vital signs.
  2. Recognise: Identify abnormal changes.
  3. Interpret: Understand what the changes mean.
  4. Act: Provide immediate care.
  5. Escalate: Call for help early.
  6. Communicate: Provide clear and accurate information.
• Importance: Acute patient deterioration is often preventable and occurs when there are failures in monitoring, recognizing, interpreting, responding, escalating, and communicating patient changes.
• Safe nursing practice requires: Consistent monitoring, clinical reasoning, prompt action, effective communication.
• Key Takeaway: Early recognition and timely intervention are critical to improving patient outcomes and preventing serious complications.

14. Primary Survey (ABCDE Approach)

• What is the Primary Survey?: A rapid, structured assessment used to identify and treat life-threatening conditions immediately.

• Purpose:

  • Quickly identify life-threatening problems.
  • Start immediate treatment.
  • Use a systematic approach.
  • Prioritize care based on severity.

• Main Goals: Ensure nothing critical is missed.

• ABCDE Approach:

  • A – Airway (with cervical spine protection): Is the airway open and clear?
  • B – Breathing (& Ventilation): Is the patient breathing effectively?
  • C – Circulation (& Haemorrhage Control): Is blood circulating properly?
  • D – Disability (Neurological Status): What is the patient’s neurological status?
  • E – Exposure (& Environmental Control): Fully assess the patient and control the environment.

• Key Rule: Always follow the order:

  • If the airway is blocked, the patient cannot breathe.
  • If the patient cannot breathe, circulation will fail.
  • Therefore, airway is always the first priority.

• Assessment Method (Look, Listen, Feel, Measure):

  • Look (Visual Inspection): Observe the patient visually.
    • Example: chest movement, skin colour, distress.
  • Listen (Auscultation): Listen for abnormal sounds.
    • Example: breathing sounds, airway noises.
  • Feel (Palpation): Use touch to assess.
    • Example: pulse, air movement, temperature.
  • Measure (Vital Signs): Check objective data.
    • Example: vital signs, oxygen saturation.

15. Airway Management

• What is the Airway?: The pathway for air to move in and out of the lungs.

  • If the airway is blocked, oxygen cannot reach the lungs, leading to rapid death.

• Cervical Spine Protection:

  • In trauma (e.g., fall, accident), assume there may be a neck injury.
  • Do not move the neck unnecessarily.
  • Use jaw thrust instead of head tilt.
  • Maintain spinal alignment.

• Life-Threatening Airway Problems:

  1. Complete Obstruction: No air can pass.
     • Causes: foreign body, vomit or blood, swelling.
     • Signs: no breath sounds, no air movement, unable to speak.
  2. Partial Obstruction: Some air passes but not enough.
     • Causes: swelling, tumour, injury.
     • Signs: noisy breathing, stridor, gurgling.
  3. Trauma-Related: Airway compromised due to injury.
     • Signs: neck swelling, tracheal deviation, C-spine injury.
  4. Medical Causes: tumours, infection, allergic reactions.

16. Airway Assessment

• Look:
  • Is the airway open?
  • Any obstruction (vomit, blood)?
  • Facial trauma or swelling?
  • Use of accessory muscles?
• Listen:
  • Stridor (upper airway obstruction), gurgling (fluid in airway), snoring (tongue obstruction), hoarseness (airway swelling), no breath sounds (severe obstruction).
• Feel:
  • Air movement at mouth and nose, neck tenderness, crepitus (air under skin), tracheal deviation.
• Measure:
  • Oxygen saturation, respiratory rate, end-tidal CO₂, arterial blood gases.

17. Airway Interventions

• 1. Clear the Airway:
  • Suction blood, vomit, secretions.
  • Remove visible foreign objects.
• 2. Manual Manoeuvres:
  • Head tilt–chin lift used if no spinal injury suspected.
  • Jaw thrust used if cervical spine injury suspected.
• 3. Airway Adjuncts:
  • Oropharyngeal airway (OPA): Used in unconscious patients to prevent tongue from blocking airway.
  • Nasopharyngeal airway (NPA): Used in semi-conscious patients and inserted through the nose.
• 4. Definitive Airway:
  • If airway cannot be maintained: endotracheal tube (intubation), laryngeal mask airway, surgical airway (in severe cases).

18. Breathing Assessment

• What is Breathing?: The process of moving air in and out of the lungs (ventilation) and getting oxygen into the blood (oxygenation).

  • If the airway is open, the patient can still die if they are not breathing effectively.

• Purpose: Check if the patient is breathing, if breathing is effective, and if the patient is getting enough oxygen.

• How to Assess Breathing: Use the structured method:

  • Look (Inspection):
    • Observe chest rise and fall, respiratory rate (normal 12-20), accessory muscle usage, cyanosis, chest shape or deformity.
      • Abnormal signs: unequal chest movement (possible pneumothorax), fast breathing (distress or hypoxia), accessory muscle use (increased effort), cyanosis (severe hypoxia).
  • Listen: Use a stethoscope to listen to the lungs.
    • Ask: Are breath sounds equal on both sides?
    • Check for abnormal sounds: wheeze (airway narrowing), crackles (fluid in lungs), diminished or absent sounds (pneumothorax), stridor (upper airway obstruction).
  • Feel: Assess with hands for:
    • Chest expansion, tracheal position, chest wall stability, subcutaneous air, tactile fremitus (vibration felt on patient’s chest wall).
      • Abnormal findings: unequal expansion (lung problem), tracheal deviation (tension pneumothorax), subcutaneous air (lung injury).
  • Measure: Check vital measurements, including oxygen saturation, respiratory rate, end-tidal CO₂, arterial blood gases.

19. Life-Threatening Breathing Problems

• 1. Pneumothorax: Air enters the chest cavity and collapses the lung.
  • Signs: unequal chest rise, shortness of breath, absent breath sounds on one side.
  • Tension pneumothorax can be fatal.
• 2. Flail Chest: Part of the chest wall moves opposite to normal.
  • Signs: paradoxical chest movement, severe pain, poor breathing.
• 3. Partial Obstruction / Respiratory Compromise:
  • Signs: rapid breathing, low oxygen levels, hypotension.

20. Levels of Respiratory Distress

• Mild Distress:

  • RR: 16-20; SpO₂ > 94%; No extra effort; Speaking full sentences; Normal mental state.

• Moderate Distress:

  • RR: 20-30; SpO₂: 90-94%; Accessory muscle use; Speaking short phrases; Anxious.

• Severe Distress:

  • RR > 30; SpO₂ < 90%; Marked effort; Speaking single words or gasping; Confused or drowsy.

• Key Point: The more severe the distress, the more urgent your intervention is.

21. Breathing Interventions

• 1. Oxygen Therapy: Used for mild to moderate problems.

  • Options include nasal prongs and simple face mask.

• 2. Non-Invasive Ventilation: Used for moderate to severe distress.

  • Includes high-flow nasal oxygen, CPAP, BiPAP to improve oxygenation without intubation.

• 3. Intubation and Ventilation: Used in severe or life-threatening situations.

  • Endotracheal tube inserted, patient connected to a ventilator.

• RATE: Rate – Auscultate – Trachea – Effort – Saturations:

  • Rate: Count respiratory rate.
  • Auscultate: Listen to breath sounds.
  • Trachea: Check if midline or deviated.
  • Effort: Look for accessory muscle use and distress.
  • Saturations: Check oxygen levels.

22. Circulation Assessment (C in ABCDE)

• Goal: Check how well blood is circulating and whether the patient is in shock or bleeding.

• 1. LOOK: Observe for visible signs of poor circulation.

  • Signs include skin color/pallor, external bleeding, jugular vein distention, obvious hemorrhage.

• 2. MEASURE (Objective Data):

  • Blood pressure (low BP → late sign of shock).
  • Heart rate (high HR = tachycardia → early sign of blood loss).
  • Hemoglobin levels (low Hb → blood loss or anemia).
  • Lactate levels (high lactate → poor oxygen delivery).
  • Urine output (low urine < 0.5 mL/kg/hr → poor kidney perfusion).

• 3. LISTEN: Auscultate for abnormal sounds.

  • Systolic and diastolic BP: narrow pulse pressure may indicate shock.
  • Heart murmurs (indicate valve dysfunction).
  • Carotid bruits (a narrowed artery sound).

• 4. FEEL (Touch):

  • Assess pulse (quality, rate, rhythm).
    • Weak, fast pulse indicates shock.
  • Skin temperature (cold = poor perfusion).
  • Moisture (sweaty or clammy = shock).
  • Central vs peripheral pulses (Central pulses may be strong while peripheral pulses are weak).
  • Abdominal tenderness (may indicate internal bleeding).

23. Circulation Life-Threatening Conditions

• 1. Cardiac Tamponade:
  • Blood or fluid builds up around the heart (pericardium).
  • Compresses the heart, reducing pumping ability.
  • Signs: Low BP, distended neck veins, muffled heart sounds.
• 2. Shock: Inadequate tissue perfusion.
  • Types include:
    • Cardiogenic Shock: Heart cannot pump effectively (causes include heart attack, heart failure).
    • Hypovolaemic Shock: Not enough circulating volume (causes include hemorrhage and dehydration).
• 3. Haemorrhage (Bleeding):
  • Loss of blood can be external (visible) or internal (hidden).
  • Major bleeding can lead to shock and death if not controlled.

24. Circulation Interventions

• 1. Control Bleeding: First priority.
  • Methods: Direct pressure, tourniquet (for severe bleeding), haemostatic dressings.
• 2. IV Access: Insert 2 large-bore cannulas (e.g., 16G or 18G) to allow rapid fluid/blood administration.
• 3. Fluid & Blood Replacement:
  • Fluids:
    • Isotonic (e.g., saline) → most commonly used.
    • Hypotonic and hypertonic solutions.
    • Colloids can also be used.
  • Blood products:
    • Packed red blood cells, plasma, platelets used when there is significant blood loss.

25. Haemorrhagic Shock Classes Based on Percentage of Blood Loss

• Class I (
• Class II (15–30%): Increased heart rate, decreased pulse pressure; patient may be anxious.
• Class III (30–40%): Marked tachycardia, decreased BP, confusion, reduced urine output.
• Class IV (>40%): Severe shock, very low BP, altered consciousness, life-threatening.
• Key Nursing Understanding:
  • Tachycardia is an early sign of shock.
  • Hypotension is a late sign.
  • Urine output is a critical indicator of perfusion.
  • Always consider: Is this patient bleeding?

26. Disability Assessment

• Purpose: Focuses on neurological status, pain, and blood glucose.

  • Helps identify life-threatening conditions such as brain injury, spinal cord injury, or hypoglycaemia.

• 1. LOOK (Observation): Check for signs like slurred speech, unusual movements, unequal pupils.

• 2. MEASURE (Objective Assessment):

  • Use ACVPU / AVPU scale to determine level of consciousness:
    • A: Alert.
    • C / V: Confused or responds to verbal stimulus.
    • P: Responds to painful stimulus.
    • U: Unresponsive.
    • Check pupil symmetry and reaction; measure blood glucose level; assess pain score (0-10).

• 3. LISTEN:

  • Slurred speech may indicate neurological injury; abnormal vocalizations may indicate distress or injury.

• 4. FEEL (Palpation):

  • Often used in Glasgow Coma Scale (GCS) assessment.
  • Check response to painful stimulus and spinal tenderness if spinal injury is suspected.

27. Common Life-Threat Conditions

• 1. Traumatic Brain Injury (TBI): Look for decreased consciousness, unequal pupils, or abnormal movements.
• 2. Spinal Cord Injury: May result in paralysis or loss of sensation; requires C-spine immobilization.
• 3. Hypoglycaemia: Severely low blood sugar can cause confusion, seizures, or unresponsiveness.

28. Disability Interventions

• 1. C-Spine Immobilisation: Use collar, backboard, or manual stabilization if spinal injury is suspected.
• 2. Glucose / Dextrose Administration: Type and route depend on severity of hypoglycaemia (oral glucose if mild; IV dextrose if severe).
• 3. Neurosurgical Referral: Requires surgery for any reduced GCS or mechanical brain injury.

29. AVPU/ACVPU Guide Level

• Alert: Fully awake, normal response.
• Confused: New or worsening confusion.
• Verbal: Responds to verbal stimulus only.
• Pain: Responds only to painful stimulus.
• Unresponsive: No response to verbal or painful stimulus.

30. Exposure Assessment

• Purpose: Ensure a complete physical exam while maintaining environmental control and patient safety.
  • Helps detect hidden injuries, bleeding, or temperature problems that could be life-threatening.
• 1. LOOK (Observation): Check skin color/pallor, external bleeding, obvious hemorrhage, bites, existing IV access.
• 2. MEASURE (Objective Assessment):
  • Assess temperature for hypothermia or fever; monitor drain volumes; confirm IV access.
• 3. LISTEN: Ask the patient where they feel pain or discomfort and prioritize complaints based on severity.
• 4. FEEL (Palpation): Check anterior/posterior surfaces; assess skin temperature; palpate for abdominal tenderness; look for deformities.

31. Life-Threats

• Hypothermia (core temp <35°C) can impair vital organ function.
• Missed injuries, especially in posterior/back areas, can go undetected if assessments are incomplete.
• Key Points: Always maintain privacy and dignity while assessing; monitor temperature to prevent complications.

32. Secondary Survey Overview

• Purpose: Conducted after stabilizing the patient in the Primary Survey (ABCDE) to identify all injuries, underlying conditions, and additional risks that require attention.
• Key Principles: Timing, systematic head-to-toe assessment, continuous reassessment and monitoring.
• 1. SAMPLE History:
  • S: Signs & Symptoms.
  • A: Allergies.
  • M: Medications.
  • P: Past Medical History.
  • L: Last Oral Intake.
  • E: Events Leading to Complaint/Injury.
• 2. Head-to-Toe Examination: Conduct thorough inspection and assessment of head, neck, chest, thorax, abdomen, pelvis, extremities, and posterior surfaces.

33. Vital Signs Reassessment

• Measure a full set of vitals after interventions to identify trends and responses.

34. Focused Assessment: Neurological

• Purpose: Detect neurological deficits, brain injury, or deterioration in mental status.
• Assess mental status, cranial nerves, motor function, and sensory function.
• Glasgow Coma Scale (GCS):
  • Eye Opening: 4 = Spontaneous; 3 = To voice; 2 = To pain; 1 = None.
  • Verbal Response: 5 = Oriented; 4 = Confused; 3 = Inappropriate words; 2 = Incomprehensible; 1 = None.
  • Motor Response: 6 = Obeys commands; 5 = Localizes pain; 4 = Withdraws from pain; 3 = Flexion to pain; 2 = Extension to pain; 1 = None.
  • Total Score: E + V + M = 3-15. Interpretation of scores: Severe (3-8), Moderate (9-12), Mild (13-15).

35. Neurological Red Flags

• GCS < 8, unequal pupils, decerebrate posturing, focal neurological deficits.
• Immediate Interventions: Secure airway if GCS < 8; monitor for Cushing’s triad, absent reflexes, seizures; consider imaging; consult neurosurgery.

36. Focused Assessment: Respiratory

• Purpose: Identify respiratory compromise and guide intervention.
• Immediate Interventions: Moderate to high-flow oxygen; position upright for ease of breathing; consider non-invasive ventilation if indicated.
• Ongoing Monitoring: Continuous SpO₂, serial arterial blood gases, chest X-ray.
• Normal Respiratory Values: RR: 12-20 breaths/min; SpO₂: >95%.
• Abnormal Sounds:
  • Wheeze: Indicates airway narrowing.
  • Rhonchi: Indicates secretions.
  • Crackles: Indicates fluid in alveoli.
  • Diminished/Absent: Poor air entry.

Conclusion

• Holistic assessment assures patient safety and effective care delivery. Use frameworks to structure your assessment and prioritize patient needs based on critical thinking, clinical reasoning, and judgment.
