🔥 Clinical Pearl #1
Topic: Hyperkalemia (ECG Trap)
💡 Key Idea:
👉 ECG changes ≠ always correlate with potassium level
⚠️ Patient may have K⁺ 7.5 mmol/L with normal ECG 😳
Again, someone with mild elevation can arrest suddenly
⸻
💎 Exam Pearl:
👉 “Treat potassium level, not ECG alone”
⸻
⚡ Emergency Rule:
👉 If K⁺ ≥6.5 OR symptoms →
✔ Calcium gluconate first (cardiac protection) ❤️
✔ Then shift K⁺ (insulin + glucose)
🔥 Clinical Pearl #2
Topic: Infective Endocarditis
💡 Classic but Missed Point:
👉 Negative blood culture ≠ rule out endocarditis
⸻
💎 Exam Pearl:
👉 “Think HACEK or prior antibiotic use”
⸻
⚠️ Clues:
✔ Fever + murmur
✔ Embolic phenomenon (stroke, splinter hemorrhage)
🔥 Clinical Pearl #3
Topic: Subarachnoid Hemorrhage (SAH)
💡 Golden Clue:
👉 “Worst headache of life” 💥
⸻
⚠️ CT scan normal after 6 hours?
👉 Doesn’t exclude SAH ❌
⸻
💎 Exam Pearl:
👉 “Next step = Lumbar puncture (look for xanthochromia)”
🔥 Clinical Pearl #4
Topic: COPD Oxygen Therapy
💡 Common Mistake:
👉 Giving high-flow O₂ blindly
⸻
⚠️ Risk → CO₂ retention → narcosis 😵
⸻
💎 Exam Pearl:
👉 Target SpO₂= 88-92%
🔥 Clinical Pearl #5
Topic: Acute Pancreatitis
💡 Diagnostic Trap:
👉 Serum amylase can be NORMAL 😳
⸻
💎 Exam Pearl:
👉 Lipase is more sensitive & specific
⸻
⚠️ ক্লিনিক্যালি strong suspicion হলে test normal হলেও ignore করবেন না
