A) 50% of patients
B) 75% of patients
C) 95% of patients
D) 99% of patients
2. A patient develops masseter muscle rigidity and a rapid rise in end-tidal CO₂ following induction with succinylcholine and sevoflurane. The most likely diagnosis is:
A) Neuroleptic malignant syndrome
B) Malignant hyperthermia
C) Thyroid storm
D) Serotonin syndrome
3. Which of the following volatile anaesthetic agents is CONTRAINDICATED in patients with renal insufficiency due to production of inorganic fluoride ions?
A) Isoflurane
B) Desflurane
C) Sevoflurane
D) Halothane
4. In a patient with a full stomach requiring emergency surgery, the preferred technique to prevent pulmonary aspiration during intubation is:
A) Awake fibreoptic intubation
B) Rapid sequence induction (RSI) with cricoid pressure
C) Inhalational induction with halothane
D) Ketamine induction without muscle relaxant
5. The "train of four" (TOF) monitoring is used to assess:
A) Depth of anaesthesia
B) Degree of neuromuscular blockade
C) Adequacy of analgesia
D) Level of neuraxial block
6. A 35-year-old patient undergoing spinal anaesthesia develops sudden hypotension, bradycardia, and nausea after injection of bupivacaine at L3-L4. The most appropriate immediate management is:
A) IV atropine alone
B) Head-down tilt, IV fluids, vasopressors (ephedrine/phenylephrine)
C) Intralipid infusion
D) Immediate general anaesthesia
7. Which of the following opioids is associated with chest wall rigidity ("wooden chest syndrome") when given rapidly in large doses?
A) Morphine
B) Pethidine
C) Fentanyl
D) Tramadol
8. The Guedel's classification describes the stages of anaesthesia. In which stage does the patient exhibit irregular breathing, breath-holding, and vomiting reflexes - making it the most DANGEROUS stage?
A) Stage I (Analgesia)
B) Stage II (Excitement/Delirium)
C) Stage III (Surgical anaesthesia)

C) 1-1.5 mg/kg (70-105 mg)
D) 3 mg/kg (210 mg)
10. Which of the following is the reversal agent for non-depolarizing neuromuscular blockade caused by rocuronium or vecuronium, that works by encapsulation rather than anticholinesterase inhibition?
A) Neostigmine
B) Edrophonium
C) Sugammadex
D) Pyridostigmine
Bonus Q:
