Key Concepts in Critical Care Nursing for Your Exam Prep
Let us explore the core topics of Critical Care Nursing that you need to know for your AIIMS NORCET 9.0, KGMU, or BTSC exams. We will focus on nursing responsibilities and exam-relevant points.
Intubation and Airway Devices
Intubation is the insertion of a tube into the trachea to maintain an open airway, often used in respiratory failure.
Airway Devices:
- Endotracheal Tube (ETT): Inserted through the mouth or nose into the trachea; used for mechanical ventilation.
- Laryngeal Mask Airway (LMA): Less invasive, placed above the glottis; used in short-term airway management.
- Oropharyngeal Airway (OPA): Prevents tongue obstruction in unconscious patients.
Complications:
- Trauma: To teeth or vocal cords during intubation.
- Infection: Ventilator-associated pneumonia (VAP) due to prolonged intubation.
- Tube Displacement: Can lead to hypoxia if dislodged.
Nursing Responsibilities:
- Confirm ETT placement post-intubation: Check for bilateral breath sounds and CO2 detection (capnography).
- Secure the tube to prevent displacement, using tape or a commercial holder.
- Provide oral care every 2 hours to reduce VAP risk, using chlorhexidine rinse.
Exams often test your knowledge of ETT placement confirmation, like using capnography.
BLS and ACLS
Basic Life Support (BLS) and Advanced Cardiac Life Support (ACLS) are protocols for managing cardiac arrest.
BLS Steps (CAB):
- Circulation: Chest compressions at 100–120/min, 2–2.4 inches deep, allow full recoil.
- Airway: Open airway using head-tilt, chin-lift (if no spinal injury suspected).
- Breathing: Give 2 rescue breaths (1 second each) if trained; otherwise, compression-only CPR.
ACLS Additions:
- Defibrillation: For shockable rhythms (e.g., ventricular fibrillation).
- Medications: Epinephrine 1 mg IV every 3–5 minutes during arrest.
- Advanced Airway: ETT or supraglottic device if needed.
Nursing Responsibilities:
- Perform high-quality CPR, ensuring minimal interruptions (<10 seconds) during compressions.
- Prepare defibrillator pads during ACLS, ensuring correct placement (right chest, left apex).
- Monitor for return of spontaneous circulation (ROSC), checking pulse and rhythm post-resuscitation.
Exams often test your understanding of BLS compression rate (100–120/min).
Mechanical Ventilation
Mechanical ventilation provides respiratory support for patients unable to breathe adequately.
Modes:
- Assist-Control (AC): Delivers a set tidal volume with each breath; used in respiratory failure.
- Synchronized Intermittent Mandatory Ventilation (SIMV): Allows spontaneous breaths between mandatory ones.
- Pressure Support Ventilation (PSV): Supports spontaneous breathing with added pressure.
Settings:
- Tidal Volume: 6–8 mL/kg of ideal body weight to prevent lung injury.
- Respiratory Rate: 12–20 breaths/min, adjusted to maintain normal CO2.
- FiO2: Start at 100%, then titrate to maintain SpO2 92–96%.
Nursing Responsibilities:
- Monitor for barotrauma (e.g., pneumothorax), noting high peak pressures (>40 cmH2O), and report promptly.
- Assess for patient-ventilator dyssynchrony, like “fighting the vent,” and adjust settings (e.g., increase sedation).
- Prevent VAP: Elevate head of bed 30–45 degrees, perform oral care, and use subglottic suctioning.
Exams often test your knowledge of tidal volume settings (6–8 mL/kg).
Patient Monitoring System
Patient monitoring systems track vital signs and other parameters in critical care settings.
Key Parameters:
- ECG: Monitors heart rate and rhythm (e.g., detect arrhythmias like ventricular tachycardia).
- SpO2: Measures oxygen saturation (normal: 95–100%; <90% indicates hypoxemia).
- End-Tidal CO2 (EtCO2): Monitors ventilation; normal: 35–45 mmHg.
- Invasive BP: Via arterial line; normal MAP: 65–110 mmHg.
Nursing Responsibilities:
- Ensure proper lead placement for ECG (e.g., V1 at 4th intercostal space, right sternal border).
- Calibrate arterial lines (zero the transducer at the phlebostatic axis) to ensure accurate BP readings.
- Respond to alarms promptly, like SpO2 <90%, by checking airway and oxygenation.
Exams often test your understanding of EtCO2 normal range (35–45 mmHg).
Defibrillator
A defibrillator delivers an electric shock to restore normal heart rhythm in cardiac arrest.
Types:
- Manual Defibrillator: Used by trained staff (e.g., in ACLS); energy set manually (e.g., 200 J biphasic).
- Automated External Defibrillator (AED): Used in BLS; automatically analyzes rhythm and prompts shock.
Procedure:
- Attach pads: Right upper chest, left lower chest (apex).
- Analyze rhythm: Shockable (e.g., VF, pulseless VT) vs. non-shockable (e.g., asystole).
- Deliver shock: Clear the patient (“I’m clear, you’re clear, everybody clear!”) before shocking.
Nursing Responsibilities:
- Ensure pad placement avoids hair or wet skin for proper contact, shaving if needed.
- Resume CPR immediately after shock for 2 minutes before reassessing rhythm.
- Check for burns post-defibrillation, applying sterile dressing if needed.
Exams often test your knowledge of shockable rhythms, like ventricular fibrillation.
Invasive Lines with Infection Control
Invasive lines include central venous catheters (CVCs), arterial lines, and pulmonary artery catheters.
Types:
- Central Venous Catheter (CVC): Used for IV fluids, medications, or CVP monitoring.
- Arterial Line: Measures blood pressure continuously; often in radial artery.
- Pulmonary Artery Catheter: Measures cardiac output and pulmonary artery pressures.
Infection Control:
- Use sterile technique during insertion: Wear gloves, mask, gown, and drape patient.
- Change dressings every 7 days or if soiled, using chlorhexidine for site cleaning.
- Monitor for infection: Redness, swelling, or pus at site; fever >100.4°F.
Nursing Responsibilities:
- Assess insertion site daily for signs of infection, reporting promptly if present.
- Flush lines with saline to maintain patency, using a 10 mL syringe to avoid excessive pressure.
- Educate staff on hand hygiene before handling lines, reducing catheter-related bloodstream infections (CRBSI).
Exams often test your knowledge of infection control, like using chlorhexidine for dressing changes.
Emergency Equipment
Emergency equipment is essential for rapid response in critical care settings.
Key Equipment:
- Crash Cart: Contains defibrillator, medications (e.g., epinephrine), and airway supplies.
- Suction Device: Clears airway secretions; wall-mounted or portable.
- Oxygen Supply: Nasal cannula, non-rebreather mask, or bag-valve-mask (BVM).
Nursing Responsibilities:
- Check crash cart daily: Ensure medications are unexpired, defibrillator is charged, and supplies are stocked.
- Test suction device before each shift, ensuring pressure is adequate (80–120 mmHg for adults).
- Verify oxygen tank levels, ensuring availability for emergencies (e.g., >500 psi).
Exams often test your knowledge of crash cart contents, like including epinephrine.
Shock
Shock is a life-threatening condition where tissue perfusion is inadequate, leading to organ failure.
Types:
- Hypovolemic Shock: Due to blood/fluid loss (e.g., hemorrhage); signs: tachycardia, hypotension.
- Cardiogenic Shock: Due to heart failure (e.g., MI); signs: jugular vein distension, pulmonary edema.
- Septic Shock: Due to infection; signs: fever, vasodilation, warm skin early.
- Anaphylactic Shock: Due to allergic reaction; signs: urticaria, bronchospasm.
Management:
- Fluids: IV crystalloids (e.g., normal saline) for hypovolemic shock; 30 mL/kg bolus.
- Vasopressors: Norepinephrine for septic shock to maintain MAP >65 mmHg.
- Oxygen: Maintain SpO2 >94% with supplemental oxygen.
Nursing Responsibilities:
- Monitor lactate levels (>2 mmol/L indicates tissue hypoperfusion) and report elevated values.
- Position patient supine with legs elevated 30 degrees in hypovolemic shock, unless contraindicated.
- Administer epinephrine (0.3–0.5 mg IM) for anaphylactic shock, monitoring for tachycardia.
Exams often test your knowledge of shock types, like septic shock showing warm skin early.
