Sample questions
Q1. Local anaesthetic systemic toxicity: the initial lipid emulsion bolus is:
- 20% lipid 1.5 mL/kg
- 20% lipid 5 mL/kg
- 10% lipid 1.5 mL/kg
- 20% lipid 0.5 mL/kg
Show answer
Answer A: 20% lipid 1.5 mL/kg
Give 20% lipid emulsion 1.5 mL/kg over 1 min, then infusion 15 mL/kg/h; repeat bolus up to twice and double the infusion rate if unstable. Reduce adrenaline boluses to ≤1 mcg/kg.
Exam style: EDAIC
Q2. Which needle gives the lowest risk of post-dural puncture headache?
- 22G Quincke
- 25G Quincke
- 25G Whitacre
- 20G Tuohy
Show answer
Answer C: 25G Whitacre
Atraumatic (pencil-point) needles such as Whitacre or Sprotte separate rather than cut dural fibres; a smaller gauge further lowers PDPH risk.
Exam style: AIIMS INI-SS
Q3. Tuffier's line (intercristal line) corresponds to which vertebral level in most adults?
- L2
- L3
- L4
- S1
Show answer
Answer C: L4
The intercristal line crosses L4 body or the L4–L5 interspace. Studies show palpation is often inaccurate, so the actual level may be higher.
Exam style: NEET-SS Anaesthesia
