Stage 2 Complete dilation → birth of baby. Stage 3 Birth of baby → delivery of placenta. Stage 4 Immediate postpartum recovery. ⸻ Apgar At approximately 1 and 5 minutes. A P G A R A – Appearance P – Pulse G – Grimace A – Activity R – Respiration Each scored 0–2. Apgar helps assess newborn adaptation; it does not by itself diagnose asphyxia or determine long-term prognosis. ⸻ Newborn Assessment Assess: * Respiratory effort * Heart rate * Temperature * Colour * Tone * Feeding * Reflexes * Weight * Head circumference * Urine/stool ⸻ Breastfeeding Benefits: * Nutrition * Immune protection * Bonding Signs of effective feeding: * Good latch * Audible swallowing * Appropriate wet/dirty diapers * Expected weight pattern ⸻ 👶 PEDIATRIC NURSING Development General progression: Head → toe Simple → complex Large muscles → fine motor Always consider developmental stage when communicating with children. ⸻ Pediatric Safety Big priorities: * Falls * Choking * Burns * Poisoning * Drowning * Car-seat safety * Medication dosing * Safe sleep Medication principle Pediatric medications are often based on: weight (kg) Always verify calculations and concentrations. ⸻ Pediatric Asthma Same basic principles as adults: * Bronchodilator for acute symptoms * Controller medications for long-term control * Trigger avoidance * Asthma action plan ⸻ RSV Common in infants/young children. Signs: * Rhinorrhea * Cough * Wheezing * Increased work of breathing * Poor feeding Priority: Respiratory assessment and hydration. ⸻ Croup Classic: Barking cough + stridor Often worse at night. Severe respiratory distress requires urgent intervention. ⸻ Cystic Fibrosis Thick secretions affect lungs and GI system. Think: “Thick mucus + lung infections + malabsorption.” Nursing: * Airway clearance * Nutrition * Pancreatic enzymes when prescribed * High-calorie/high-protein nutrition * Infection prevention ⸻ Gastroenteritis Major concern: Dehydration. Assess: * Wet diapers/urine * Mucous membranes * Tears * Capillary refill * Weight * Activity/LOC ⸻ Pyloric Stenosis Classic: Projectile, non-bilious vomiting Often occurs in young infants. Possible: * Hunger after vomiting * Dehydration * Weight loss ⸻ ASD vs VSD ASD Hole between atria. VSD Hole between ventricles. VSD can produce: A significant murmur and increased pulmonary blood flow. ⸻ Sickle Cell Disease Problem: Abnormal hemoglobin → sickled RBCs → vaso-occlusion and hemolysis. Crisis triggers: * Dehydration * Infection * Hypoxia * Stress Management: * Hydration * Oxygen if hypoxemic * Pain management * Treat infection * Rest * Disease-specific therapies ⸻ Meningitis Think: Fever + headache + stiff neck + altered mental status May also have: * Photophobia * Vomiting * Seizures Emergency. Use appropriate isolation precautions according to suspected organism and institutional policy. ⸻ Hydrocephalus Excess CSF. Infants may have: * Increasing head circumference * Bulging fontanelle * Irritability * Poor feeding * “Sunsetting” eyes Older children: * Headache * Vomiting * Visual changes * Altered LOC ⸻ 🧠 MENTAL HEALTH NURSING Therapeutic Communication DO: * Use open-ended questions * Listen * Reflect * Clarify * Validate feelings * Maintain appropriate boundaries DON’T: * Give false reassurance * Judge * Argue * Give excessive advice * Say “everything will be fine” ⸻ Depression Symptoms: * Persistent sadness * Anhedonia * Sleep changes * Appetite changes * Fatigue * Poor concentration * Feelings of worthlessness * Suicidal thoughts Nursing priority: Assess suicide risk directly. ⸻ Bipolar Disorder Mania * Elevated/irritable mood * Increased energy * Decreased need for sleep * Rapid speech * Impulsivity * Grandiosity Nursing: * Reduce stimulation * Maintain safety * Set clear limits * Encourage nutrition/hydration * Administer medications as prescribed ⸻ Schizophrenia Positive symptoms: * Hallucinations * Delusions * Disorganized speech/behaviour Negative symptoms: * Flat affect * Social withdrawal * Reduced motivation Communication Don’t argue with delusions. Instead: Acknowledge the patient’s feelings while presenting reality. ⸻ OCD Obsessions: Intrusive thoughts Compulsions: Repetitive behaviours/mental acts ⸻ Eating Disorders Watch: * Electrolytes * Cardiac rhythm * Nutrition * Weight * Refeeding complications * Psychological safety ⸻ Substance Use Priorities: * Airway/breathing/circulation * Overdose recognition * Withdrawal * Safety * Nonjudgmental communication ⸻ 🧪 HIGH-YIELD DIAGNOSTIC TEST THINKING When you see a test question, ask: “Why are they ordering this?” Examples: CT head after sudden neurological deficit → looking for bleeding/structural abnormalities. MRI → detailed soft tissue/neurological/musculoskeletal imaging. ECG → electrical activity/ischemia/dysrhythmia. Troponin → myocardial injury. HbA1c → long-term glucose control. Creatinine/GFR → kidney function. INR → warfarin effect. Culture and sensitivity → organism + effective antimicrobial. Pulmonary function test → lung function/obstruction/restriction. ⸻ 💊 PHARMACOLOGY MASTER MEMORY MAP Instead of memorizing 100 medications individually, memorize the danger associated with each class: Drug/Class Think Insulin Hypoglycemia Opioids Respiratory depression Warfarin Bleeding + INR Heparin Bleeding + HIT Furosemide Fluid/electrolyte loss Digoxin Bradycardia/toxicity ACE inhibitors Hyperkalemia + cough/angioedema Beta blockers Bradycardia/hypotension Steroids Hyperglycemia + infection NSAIDs GI bleeding + kidney injury Statins Muscle/liver effects Bronchodilators Tachycardia/tremor Inhaled steroids Oral candidiasis Antibiotics Allergy + C. diff ⸻ 🚨 THE “PRIORITY QUESTION” METHOD When you’re stuck on an exam question, ask: 1. Is the airway threatened? If yes → AIRWAY 2. Is breathing compromised? If yes → BREATHING 3. Is circulation/perfusion compromised? If yes → CIRCULATION 4. Is there an acute neurological deterioration? Think neurological emergency. 5. Is there a safety risk? Falls, suicide, aspiration, seizures, etc. 6. Which patient is deteriorating? Unstable beats stable. ⸻ ⭐ TOP THINGS I WOULD MEMORIZE FIRST If you have limited study time, prioritize these: 🚨 Emergencies * Anaphylaxis → IM epinephrine * Stroke → BE FAST + last known well * MI → ECG + rapid intervention * Sepsis → early recognition + rapid treatment * Tension pneumothorax → emergency * Severe hypoglycemia → rapid glucose treatment * Status epilepticus → emergency * Increased ICP → neurological deterioration * Hemorrhage → control bleeding + perfusion * Severe burns → ABCs 💊 Medications * Insulin → hypoglycemia * Morphine → respiratory depression * Warfarin → INR/bleeding * Heparin → bleeding/HIT * Digoxin → pulse/potassium/toxicity * Furosemide → fluid/electrolytes * Nitroglycerin → hypotension + PDE-5 interaction * Steroids → infection/hyperglycemia * Antibiotics → allergy/C. diff * Inhaled steroids → rinse mouth 🧪 Labs * Hb → oxygen carrying * WBC → infection/immune response * Platelets → bleeding/clotting * INR → warfarin * Glucose → current sugar * HbA1c → long-term glucose * Creatinine/GFR → kidney * K⁺ → heart rhythm * Na⁺ → neurological/fluid balance * Culture → organism * Sensitivity → antibiotic choice 🩺 Nursing skills * Infection control * Medication administration * IVs * Oxygen * Suction * Tracheostomy * Chest tubes * Urinary catheter * Wound care * Ostomy care * Vital signs * Neurovascular assessment * Respiratory assessment ⸻ 📚 How I’d recommend studying this huge syllabus Don’t try to study all of these diseases in one sitting. Use system blocks: Day 1: Diabetes + cardiovascular Day 2: Respiratory + renal Day 3: GI + liver Day 4: Hematology + immune/infection Day 5: Neuro + musculoskeletal Day 6: Maternal/newborn Day 7: Pediatrics Day 8: Mental health Day 9: Pharmacology Day 10: Labs + diagnostics + clinical skills Day 11: Emergency/priority questions Day 12: Full mixed practice exam + review weak areas For each condition, make yourself answer only 5 questions: 1. What is happening? 2. What will I assess? 3. What is the biggest complication? 4. What will I do first? 5. What do I teach the patient? That approach will help you think like a nurse rather than memorize isolated facts, which matches the study framework you were given.
