Q1 · Arsenic Poisoning
NEET PGMediumExplanation
Chronic arsenic poisoning causes Mees' lines, transverse white bands on the nails, and rain-drop pigmentation of the skin. The antidote is dimercaprol, and arsenic is historically called inheritance powder.
Q2 · Lead Poisoning
NEET PGMediumExplanation
Lead poisoning produces Burton's line, a blue-black gum margin, along with basophilic stippling, anaemia, wrist drop and abdominal colic. Chelation uses calcium disodium EDTA, DMSA or D-penicillamine.
Q3 · Organophosphate Poisoning
NEET PGEasyExplanation
Organophosphates inhibit acetylcholinesterase, and a reduced plasma pseudocholinesterase level confirms exposure. Clinically there is a cholinergic crisis, and treatment is atropine plus pralidoxime.
Q4 · Carbon Monoxide
EasyExplanation
Carbon monoxide binds haemoglobin with about 200 to 250 times the affinity of oxygen, forming carboxyhaemoglobin and impairing oxygen delivery. It causes cherry-red lividity, and treatment is high-flow or hyperbaric oxygen.
Q5 · Dhatura Poisoning
MediumExplanation
Dhatura contains atropine, hyoscine and hyoscyamine, producing anticholinergic effects: dry mouth, dilated pupils, delirium, hot dry skin and tachycardia. It is used for stupefaction to commit robbery.
Q6 · Opioid Poisoning
EasyExplanation
Opioid poisoning presents with pinpoint pupils, respiratory depression and coma. The specific antidote is naloxone, which may need repeat dosing because of its short half-life.
Q7 · Snake Bite
HardExplanation
Elapid venom, from cobras and kraits, is chiefly neurotoxic, causing ptosis, bulbar palsy and respiratory paralysis. Viper venom is mainly vasculotoxic and haemotoxic. Polyvalent antivenom is the treatment.
Q8 · Postmortem Alcohol
MediumExplanation
Vitreous humour is preferred for postmortem alcohol estimation because its isolated location resists bacterial alcohol production and diffusion, giving a reliable value. Urine is also useful.
Q9 · Corrosive Poisoning
MediumExplanation
In corrosive ingestion, emesis and gastric lavage are contraindicated because they re-expose the oesophagus to the corrosive and risk perforation. Management is supportive, and strong chemical neutralisation is avoided as it generates heat.
Q10 · Viscera Preservation
HardExplanation
Saturated common salt solution is the routine viscera preservative. Rectified spirit is used except where alcohol or organophosphate poisoning is suspected. Formalin is avoided as it interferes with analysis.
Toxicology sits within Forensic Medicine, which carries the same syllabus in both exams. This set runs to 10 questions, each tagged Easy, Medium or Hard, 2 of them at Hard, and 3 drawn from previous-year papers.
Answer first, then read the explanation even on the ones you got right — the reasoning is where Toxicology marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Forensic Medicine examiners keep returning to.
