Coroner's inquest is still conducted in mumbai.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because coroner's inquests are not conducted in Mumbai. A coroner's inquest is a legal process where a coroner investigates the cause and circumstances of a person's death. In India, coroner's inquests are not a common practice and are not conducted in Mumbai or any other city. Instead, the cause of death is usually determined by a medical professional or through a police investigation.Rate this question:

‘Mees’ lines in the nails & rain drop pigmentation of skin are characteristic of this poisoning
- A.
Lead
- B.
Arsenic
- C.
Zinc
- D.
Thallium
Correct Answer
B. ArsenicExplanation
Mees' lines in the nails and raindrop pigmentation of the skin are characteristic symptoms of arsenic poisoning. Arsenic is a toxic element that can be found in various sources, including contaminated water, certain foods, and industrial processes. When arsenic enters the body, it can cause a range of symptoms, including skin discoloration and changes in the nails. Mees' lines are horizontal white bands that appear on the nails, while raindrop pigmentation refers to small, dark spots on the skin. Therefore, arsenic is the correct answer in this case.Rate this question:

A young male was brought by police from the railway platform to you. He is talking irrelevant. He is having dry mouth, hot skin, dilated pupils, staggering gait and slurred speech. What is your most probable diagnosis ?
- A.
Organophosphorous poisoning
- B.
Carbamates poisoning
- C.
Dhatura poisoning
- D.
Alcohol intoxication
Correct Answer
C. Dhatura poisoningExplanation
Based on the symptoms described, including dry mouth, hot skin, dilated pupils, staggering gait, and slurred speech, the most probable diagnosis is Dhatura poisoning. Dhatura is a plant that contains toxic substances called tropane alkaloids, which can cause hallucinations, confusion, delirium, and other neurological symptoms. These symptoms align with the individual's irrelevant speech and altered motor function. Organophosphorous and carbamates poisoning typically present with different symptoms, such as excessive sweating, excessive salivation, and muscle twitching. Alcohol intoxication may cause similar symptoms, but the combination of dry mouth, hot skin, dilated pupils, and staggering gait is more indicative of Dhatura poisoning.Rate this question:

Chromodacryorrhea is seen in
- A.
Organophosphorous poisoning
- B.
Carbamates poisoning
- C.
Dhatura poisoning
- D.
Alcohol intoxication
Correct Answer
A. OrganopHospHorous poisoningExplanation
Chromodacryorrhea refers to the excessive tearing or lacrimation, which can be seen in certain conditions. In this case, the correct answer is organophosphorous poisoning. Organophosphorous compounds are commonly used in pesticides and insecticides. When ingested or exposed to these compounds, they can lead to various symptoms including excessive tearing. This is due to the toxic effects of organophosphorous compounds on the nervous system, specifically on the parasympathetic nervous system, which controls tear production. Therefore, chromodacryorrhea is a characteristic feature of organophosphorous poisoning.Rate this question:

Pralidoxime (P2AM) should not be used in
- A.
Organophosphorous poisoning
- B.
Carbamates poisoning
- C.
Both
- D.
None
Correct Answer
B. Carbamates poisoningExplanation
Pralidoxime (P2AM) should not be used in carbamates poisoning because it is only effective in treating organophosphorous poisoning. Carbamates are a different class of pesticides that inhibit the enzyme acetylcholinesterase, similar to organophosphates, but pralidoxime does not have the same efficacy in reversing the effects of carbamates. Therefore, it is important to use alternative treatments specific to carbamates poisoning.Rate this question:

McEwan's Sign is seen in (pinching skin of face or neck would cause transient dilation of the pupils.)
- A.
Organophosphorous poisoning
- B.
Carbamates poisoning
- C.
Alcohol poisoning
- D.
Arsenic poisoning
Correct Answer
C. Alcohol poisoningExplanation
McEwan's Sign refers to the transient dilation of the pupils when the skin of the face or neck is pinched. This phenomenon is commonly observed in cases of alcohol poisoning. Alcohol poisoning occurs when an individual consumes a large amount of alcohol in a short period, leading to a toxic buildup in the body. One of the effects of alcohol poisoning is the impairment of the autonomic nervous system, which can cause abnormal pupil responses such as dilation. Therefore, the presence of McEwan's Sign suggests alcohol poisoning as the likely cause.Rate this question:

Rigor mortis does not develop in a fetus below 7 months of age.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Rigor mortis is the stiffening of the muscles that occurs after death. It is a natural process that begins a few hours after death and lasts for a certain period of time. However, in the case of a fetus below 7 months of age, rigor mortis does not develop. This is because the muscles of a fetus are not fully developed and do not have the same ability to contract and stiffen as the muscles of a fully developed body. Therefore, the statement that rigor mortis does not develop in a fetus below 7 months of age is true.Rate this question:
-
- 12.
Rigor mortis appear in this internal organ first
- A.
Heart
- B.
Eye
- C.
Ear
- D.
None
Correct Answer
A. HeartExplanation
Rigor mortis is the stiffening of muscles after death due to a lack of ATP. This process starts within a few hours and gradually spreads throughout the body. The heart is a vital organ that continuously contracts and relaxes, requiring a high amount of ATP. Therefore, it is logical to assume that the heart would be one of the first internal organs to exhibit rigor mortis. The eye and ear do not have muscles that would undergo this process, making them less likely candidates.Rate this question:

Most reliable criteria in Gustafson’s method of identification is
- A.
Cementum apposition
- B.
Root resorption
- C.
Transparency of root
- D.
Attrition
Correct Answer
C. Transparency of rootExplanation
In Gustafson's method of identification, transparency of root is considered the most reliable criteria. This means that the root of the tooth becomes more translucent as a person ages. This transparency is caused by the loss of dentin and the decrease in the number of dentinal tubules. By examining the level of transparency in the root, dental professionals can estimate the age of an individual. This method is often used in forensic dentistry to determine the age of unidentified human remains.Rate this question:

Priapism is seen in which poisoning ?
- A.
Cantharide poisoning
- B.
Snakebite
- C.
Lead poisoning
- D.
Arsenic poisoning
Correct Answer
A. Cantharide poisoningExplanation
Priapism is a condition characterized by persistent and painful erections that can last for several hours. It is commonly associated with cantharide poisoning, which occurs when someone ingests or comes into contact with the venomous substance produced by blister beetles. Cantharidin, the active ingredient in cantharides, can cause severe irritation and inflammation of the genitourinary tract, leading to priapism. Snakebite, lead poisoning, and arsenic poisoning do not typically cause priapism.Rate this question:

Spalding sign is seen in
- A.
Maceration
- B.
Drowning
- C.
Mummification
- D.
Starvation
Correct Answer
A. MacerationExplanation
The Spalding sign refers to the separation of the cranial bones in a newborn due to maceration, which is the softening and breakdown of the skin and tissues caused by prolonged exposure to moisture. This can occur in stillborn infants or those who have been in a watery environment for an extended period of time, such as during a prolonged labor or in cases of intrauterine death. The separation of the cranial bones is a result of the breakdown of the connective tissue between them, leading to the characteristic Spalding sign.Rate this question:

A group of muscles were in state of violent contraction prior to death and they remained so even after death. It was very difficult to break this condition. What could it be ?
- A.
Gas stiffening
- B.
Cold stiffening
- C.
Cadaveric spasm
- D.
Rigor mortis
Correct Answer
C. Cadaveric spasmExplanation
Cadaveric spasm is the correct answer because it refers to a condition where the muscles of a dead body remain in a state of violent contraction. This condition occurs prior to death and continues even after death. It is difficult to break this condition, indicating that the muscles are stiff and rigid. Gas stiffening and cold stiffening are not accurate explanations for this phenomenon. Rigor mortis, while similar to cadaveric spasm, refers specifically to the stiffening of muscles after death due to chemical changes in the body.Rate this question:

Which is the first permanant teeth to appear ?
- A.
First Molar
- B.
Central incisor
- C.
Lateral incisor
- D.
Canine
Correct Answer
A. First MolarExplanation
The first permanent teeth to appear are the first molars. These teeth typically erupt around the age of 6, before any other permanent teeth. They are located at the back of the mouth and are important for chewing and grinding food. The central and lateral incisors and canines are also permanent teeth, but they usually erupt after the first molars.Rate this question:

4 - 6 yrs
- B.
5 - 9 yrs
- C.
5 - 13 yrs
- D.
6 - 11 yrs
Correct Answer
D. 6 - 11 yrsExplanation
The period of mixed dentition refers to the time when a child has a combination of both primary (baby) teeth and permanent (adult) teeth in their mouth. This typically occurs between the ages of 6 and 11 years. During this period, the primary teeth start to fall out and are gradually replaced by permanent teeth. This is an important stage in dental development as it marks the transition from baby teeth to adult teeth.Rate this question:

Gettler’s test is done for death by
- A.
Hanging
- B.
Drowning
- C.
Burns
- D.
OPC poisoning
Correct Answer
B. DrowningExplanation
Gettler's test is a method used to determine if a person has died from drowning. It involves examining the lungs for the presence of diatoms, which are microscopic algae found in water. If diatoms are found in the lungs, it indicates that the person was alive at the time of submersion and therefore likely died from drowning. This test is useful in cases where the cause of death is unclear or when there is suspicion of foul play.Rate this question:

Magnan's symptom or Tactile hallucinations are characteristic of
- A.
Cocaine
- B.
Alcohol
- C.
Cannabis
- D.
Benzodiazepines
Correct Answer
A. CocaineExplanation
Magnan's symptom or tactile hallucinations are characteristic of cocaine use. Tactile hallucinations refer to the perception of physical sensations that are not actually present. This can include sensations like bugs crawling on the skin or a feeling of something crawling under the skin. Cocaine use can cause these hallucinations as a result of its stimulant effects on the central nervous system. It can disrupt the normal functioning of neurotransmitters in the brain, leading to altered perceptions and sensations. Alcohol, cannabis, and benzodiazepines are not typically associated with Magnan's symptom or tactile hallucinations.Rate this question:

"when there is a contact between two items, there will be an exchange" is
- A.
Mc naughten's rule
- B.
Rule of hasse
- C.
Locard's exchange principle
- D.
Quetlet’s rule
Correct Answer
C. Locard's exchange principleExplanation
Locard's exchange principle states that when there is contact between two items, there will be an exchange of materials. This principle is often applied in forensic science, where it is believed that every contact leaves a trace. It suggests that during a crime, the perpetrator will leave behind evidence at the crime scene and also take away evidence with them. This principle emphasizes the importance of thoroughly examining and analyzing the trace evidence left behind to link individuals to a crime.Rate this question:
