Forensic Toxicology Questions Set-2

Q1. Father of toxicology is?

a. Paracelsus

b. Galen

c. Galton

d. Orfila

ANSWER:

d. Orfila

Q2. A dead body is having cadaveric lividity of bluish green color. The most likely cause of death is by?

a. Hydrocyanic poisoning

b. Hydrogen sulphide poisoning

c. Oleander poisoning

d. Sodium nitrite poisoning

ANSWER:

b. Hydrogen sulphide poisoning

EXPLANATION:

Hydrogen sulphide poisoning often leads to a bluish-green discoloration in the body due to the formation of sulph-haemoglobin in the blood.

While hydrocyanic poisoning can cause rapid death due to its interference with cellular respiration, the color of the cadaveric lividity in this case is more likely to be pink or cherry red rather than bluish green.

Oleander poisoning primarily affects the cardiovascular system, and the resulting discoloration in the body is less likely to be a bluish green and more likely to be related to other organ failure

Sodium nitrite poisoning leads to the formation of methemoglobin, which can give the skin a brownish or chocolate color.

Q3. In which case of poisoning do we have a smell of burnt rope?

a. Aluminium phosphide

b. Cyanide

c. Cannabis

d. Arsenic

ANSWER:

 c. Cannabis

Q4. In case of mercury poisoning, which part of kidneys will be affected?

a. PCT (Proximal convulated duct)

b. DCT (Distal convulated duct)

c. Collecting duct

d. Loop of Henle

ANSWER:

a. PCT

EXPLANATION:

Mercury tends to accumulate primarily in the proximal tubules of the kidney, where it can cause damage to the epithelial cells, leading to various kidney issues like proteinuria (excess protein in urine) and nephrotoxicity (kidney damage).

Q5. Which of the following is not the universal antidote?

a. Powdered charcoal

b. Tannic acid

c. Ground mustard

d. Magnesium oxide

ANSWER:

b. Ground mustard

EXPLANATION:

Ground mustard is not considered a universal antidote and is primarily used as an emetic (inducing vomiting) in certain poisoning situations.

Q6. Which of the following is not treated using BAL?

a. Lead poisoning

b. Mercury poisoning

c. Cadmium poisoning

d. Arsenic poisoning

ANSWER:

       c. cadmium poisoning

EXPLANATION:

BAL (British Anti-Lewisite) is the brand name for Dimercaprol, a chelating agent used to treat heavy metal poisoning.

Complexes formed by combining cadmium / iron with BAL are toxic. Hence BAL (dimercaprol) is contraindicated in treatment of iron / cadmium poisoning.

Q7. In which case of poisoning, disodium EDTA is used as an antidote?

a. Mercury

b. OPC

c. Mushroom

d. Belladona

ANSWER:

a. Mercury

Q8. Which chelating agent is given by oral route for copper, mercury and lead poisoning?

a. BAL

b. EDTA

c. Penicillamine

d. Succimer

ANSWER:

c. Penicillamine

EXPLANATION:

Penicillamine is an oral chelating agent that can be used to treat various heavy metal poisonings, including copper, mercury, and lead, although it's primarily used for copper poisoning in Wilson's disease.

Q9. Which antedote can be used in the cases of cyanide poisoning?

a. Flumazenil

b. Sodium nitrite

c. Physostigmine

d. Naloxone

ANSWER:

c. Sodium nitrite

EXPLANATION:

Cyanide poisoning occurs when cyanide binds to an enzyme called cytochrome c oxidase, preventing cells from using oxygen. Antidotes like sodium nitrite work by helping the body form a less toxic compound with cyanide, allowing it to be eliminated from the body.

Q10. Which of the following is not a cardiac poison?

a. Digitalis

b. Oleander

c. Aconite

d. Nux vomica

ANSWER:

e. Nux vomica

EXPLANATION:

Digitalis, Oleander, and Aconite: These are all considered cardiac poisons because they contain compounds called cardiac glycosides, which can directly affect the heart muscle and cause serious toxicity.

While highly toxic, Nux vomica primarily contains strychnine and brucine, which primarily affect the nervous system, causing muscle spasms and hyper excitability, not directly the heart muscle.
