Pharmacology questions in AIIMS NORCET are highly practical. Instead of asking simple drug actions, the examiners test your ability to monitor side effects, identify toxicities, and perform dose calculations in real-time clinical situations.
Top 5 Drug Classes to Focus On
If you are short on time, ensure you thoroughly revise these high-yield drug classes:
- Cardiovascular Drugs: Digoxin (toxicity levels, apical pulse check), Antihypertensives (Beta-blockers, ACE inhibitors side effects), and Nitroglycerin administration.
- Anticoagulants: Heparin (monitor aPTT, antidote: Protamine Sulfate) and Warfarin (monitor PT/INR, antidote: Vitamin K).
- Endocrine Drugs: Insulin types (onset, peak, duration of action) and Oral Hypoglycemics.
- Emergency Drugs: Adrenaline, Atropine, Amiodarone, and Adenosine protocols.
- Antibiotics: Aminoglycosides (ototoxicity & nephrotoxicity monitoring) and Vancomycin (Red Man Syndrome).
Golden Rule: Always check the patient's vitals before administering potent drugs. For instance, withhold Digoxin if the heart rate is less than 60 bpm.
Crucial Pediatric Dose Calculations
You can expect at least 1-2 questions testing drug dosage math. Master the standard formulas:
- IV Flow Rate (gtts/min) = (Total Volume in mL × Drip Factor) ÷ Total Time in minutes
- Desired Dose calculation = (Doctor's Order ÷ Stock Available) × Quantity in hand
Memory Hack: Use mnemonics for drug antidotes. For example, 'He P-rotates' -> Heparin = Protamine Sulfate; 'War-K-fare' -> Warfarin = Vitamin K.
