📌 Quick Memory:

• Injury chemicals = H, B, P, G → Histamine, Bradykinin, Prostaglandin, Glutamate
• Chronic pain causes = AFL → Arthritis, Fibromyalgia, Low back pain
• Consolability = “Can comfort calm them?”
• CO poisoning = “Cherry Red” → skin, lips, nail beds (even in dark-skinned patients)
• Seborrheic keratosis = “Stuck-on & Safe” → benign, do not become cancerous
• Intercostal spaces = Named by rib above
• Goblet cells = “Make mucus to trap dust” → entrap small particulate matter
• Hypercapnia = “High CO₂ in blood”
• Scoliosis = “Adolescents most affected”
• Right lung = “Shorter (liver pushes up)”
• Posterior chest = “Lower lobes best heard”
• Tactile fremitus ↓ = “Pleural effusion” → fluid blocks vibration
• Percussion depth = 5–7 cm
• Heart failure = “Crackles at lung bases” → fluid backs up into alveoli
• Rhonchal fremitus = “Thick bronchial secretions”
• Bradypnea (8/min) = “Drug-induced depression (CNS depressants, opioids)”
• Forced inspiration (after exercise) = Accessory muscles: Scalenes, Sternomastoids, Trapezii
• Daytime cough = “Work irritants” → subsides at night
• Whispered pectoriloquy = “Whisper heard clearly” → sign of consolidation
• Cough types = “Hack–Dry–Bark–Congested” → Mycoplasma = hacking, HF = dry, Croup = barking, Colds/Bronchitis/Pneumonia = congested
• Occasional sighing = “Alveolar expansion”
• Mediastinum = “H-T-E” → Heart, Trachea, Esophagus
• Tactile fremitus technique = “Palmar base of hand on chest”
• Forced inspiration = “Extra helpers: Scalenes, Sternomastoids, Trapezii”
• Cardio assessment = “Start with Pulse & BP first”
• Semilunar valves = “Between ventricles & arteries” (Aortic + Pulmonic)
• S1 (first heart sound) = “Mitral & Tricuspid close”
• S2 (second heart sound) = “Aortic & Pulmonic close”
• Thrill = “Palpable vibration in chest”
• Lymphedema precaution = “No cuff on lymph-side”

📌 Quick Memory Tip (Restarted List):

1. Intermittent claudication = “PAD pain: walk → pain, rest → relief.”
2. Major PAD risk = “Smoking #1 modifiable risk.”
3. Posterior tibial pulse = “Behind medial malleolus.”
4. Venous return = “Calf pump + valves = peripheral heart.”
5. Modified Allen test = “Color return ≤10 sec = good collateral flow.”
6. Arterial insufficiency = “Thin shiny skin, ridged nails, hair loss.”
7. Venous stasis risk = “Pregnancy → uterus compresses veins.”
8. Pitting edema = “4+ = very deep, gross swelling, long-lasting.”
9. ABI = “Ankle systolic ÷ Brachial systolic = PAD test.”
10. Pregnancy edema = “Uterus compresses iliac veins + IVC.”
11. Pain reassessment oral analgesics = “Check every 60 min.”
12. Painful mononeuropathy = “Nerve root compression.”
13. Fatigue teaching error = ❌ Actually, fatigue ↑ pain & ↓ coping.
