Correct answer: A — Only IV induction agents are safe near MRI

The most critical safety consideration for anaesthesia in MRI is ensuring all equipment is MRI-conditional (safe for the specific field strength). Ferromagnetic objects become lethal projectiles in the magnetic field. All monitoring equipment (pulse oximeter, NIBP, capnograph), infusion pumps, laryngoscope, airway equipment, and anaesthetic machine must be specifically certified for use at the MRI field strength. Standard anaesthetic machines, laryngoscopes, and stethoscopes are FERROMAGNETIC and must never enter the scanner room.
