Violence Risk Assessment Indian Medical PG Practice Questions and MCQs
Question 1: In an accident case, after the arrival of medical team, all should be done in early management except;
- A. Glasgow coma scale
- B. Check BP (Correct Answer)
- C. Stabilization of cervical vertebrae
- D. Check Respiration
Explanation: ***Check BP*** - In the **immediate/early management** of trauma (primary survey), while circulation assessment is crucial, the **initial assessment of circulation** focuses on: - **Pulse rate and quality** (radial, carotid) - **Capillary refill time** - **Skin color and temperature** - **Active hemorrhage control** - **Formal blood pressure measurement** with a cuff, while important, is typically recorded during or after these rapid initial assessments, as it takes more time to obtain an accurate reading. - In the context of this question, among the four options listed, BP measurement is relatively less immediate compared to the other life-saving priorities (airway protection, breathing assessment, C-spine stabilization, and GCS). - **Note:** This is a nuanced distinction - BP is assessed during primary survey, but the other three options have more immediate life-threatening implications if not addressed. *Glasgow coma scale* - **GCS assessment** is part of the **"D" (Disability)** step in the ATLS primary survey. - It is performed early to assess neurological status and level of consciousness. - GCS <8 indicates need for **definitive airway protection** (intubation). - This is a critical early assessment that guides immediate management decisions. *Stabilization of cervical vertebrae* - **C-spine immobilization** is part of the **"A" (Airway)** step - "Airway with cervical spine protection." - It is performed **simultaneously** with airway assessment using a **rigid cervical collar**. - This is the **first priority** in trauma management to prevent secondary spinal cord injury. - All trauma patients should be assumed to have C-spine injury until proven otherwise. *Check Respiration* - **Respiratory assessment** is part of the **"B" (Breathing)** step in the ATLS primary survey. - This involves checking: - **Respiratory rate and pattern** - **Chest wall movement** - **Air entry bilaterally** - **Signs of tension pneumothorax or flail chest** - This is an immediate life-saving priority and must be assessed early.
Question 2: Antidote for benzodiazepine poisoning: FMGE 10, 13; NEET 14
- A. Flumazenil (Correct Answer)
- B. Naloxone
- C. Atropine
- D. N-acetyl-cysteine
Explanation: ***Flumazenil*** - **Flumazenil** is a competitive **benzodiazepine receptor antagonist** that can reverse the sedative and other central nervous system effects of benzodiazepines. - It works by blocking benzodiazepines from binding to their receptor sites on the **GABA-A receptor complex**. *Naloxone* - **Naloxone** is a competitive **opioid receptor antagonist** used to reverse opioid overdose. - It has no effect on **benzodiazepine toxicity** as it targets different receptor systems. *Atropine* - **Atropine** is an **anticholinergic drug** used to reverse the effects of **cholinergic poisoning** (e.g., from organophosphates, carbamates) or symptomatic bradycardia. - It works on muscarinic acetylcholine receptors and is not involved in benzodiazepine metabolism or action. *N-acetyl-cysteine* - **N-acetyl-cysteine (NAC)** is primarily used as an antidote for **acetaminophen (paracetamol) poisoning**, where it replenishes glutathione. - It is also used in some cases of mucolysis but has no role in reversing benzodiazepine toxicity.
Question 3: A neonate born at home is found dead with skull base fracture, depressed temporal bone fracture, and brain contusions. What is the most likely manner of death?
- A. Natural causes
- B. Homicide (Correct Answer)
- C. Undetermined
- D. Accidental death
Explanation: ***Homicide*** - The combination of **skull base fracture**, **depressed temporal bone fracture**, and **brain contusions** in a neonate strongly indicates **non-accidental trauma** (infanticide) - These are **high-energy injuries** requiring **forceful impact**, incompatible with normal birth trauma or typical handling - The pattern of multiple severe traumatic injuries points to **intentional harm** *Natural causes* - Natural infant deaths result from congenital anomalies, infections, or genetic disorders - **Traumatic skull fractures** and **brain contusions** are not manifestations of natural disease processes *Undetermined* - Used when insufficient evidence exists to classify the manner of death - The **specific pattern of severe traumatic injuries** provides clear evidence of non-natural violent death, making this classification inappropriate *Accidental death* - Normal birth trauma may cause minor injuries (cephalohematoma, linear skull fractures) - The presence of **multiple severe fractures** (skull base + depressed temporal bone) with **brain contusions** exceeds the injury pattern of accidental birth trauma or postnatal accidents - Such extensive injuries in a neonate indicate intentional violence rather than accident
Question 4: CAGE questionnaire is used in:
- A. Opiate poisoning
- B. Alcohol dependence (Correct Answer)
- C. Dhatura poisoning
- D. Barbiturate poisoning
Explanation: ***Alcohol dependence*** - The **CAGE questionnaire** is a widely used screening tool for identifying potential **alcohol problems** and dependence. - The acronym CAGE stands for Cutting down, Annoyance by criticism, Guilty feelings, and Eye-openers, all related to drinking habits. *Opiate poisoning* - Screening for opiate use or poisoning typically involves asking about **drug use history**, conducting **urine drug screens**, and observing specific clinical signs like **pinpoint pupils** and **respiratory depression**. - The CAGE questionnaire is not designed to screen for opiate use. *Dhatura poisoning* - **Dhatura poisoning** is characterized by anticholinergic symptoms like **dilated pupils**, **dry mouth**, **tachycardia**, and **delirium**. - Diagnosis relies on clinical presentation and a history of exposure, not a specific questionnaire like CAGE. *Barbiturate poisoning* - **Barbiturate poisoning** presents with central nervous system depression, including **sedation**, **respiratory depression**, and **hypotension**. - Diagnosis involves a clinical assessment, history of barbiturate use, and toxicology screens, not the CAGE questionnaire.
Question 5: Diazepam poisoning is treated by:
- A. Resins
- B. Hemofiltration
- C. Charcoal
- D. Flumazenil (Correct Answer)
Explanation: ***Flumazenil*** - **Flumazenil** is a **benzodiazepine receptor antagonist** that competitively binds to the benzodiazepine binding site on the GABA-A receptor, reversing the effects of diazepam. - It is used in cases of severe benzodiazepine overdose causing **respiratory depression** or **severe sedation**. *Resins* - **Resins**, such as **cholestyramine**, are typically used to bind toxins or drugs in the **gastrointestinal tract** that undergo enterohepatic recirculation. - They are generally not effective for reversing the central nervous system depression caused by a benzodiazepine overdose. *Hemofiltration* - **Hemofiltration** is a form of renal replacement therapy used to remove small and middle molecular weight substances from the blood. - While it can remove some drugs, **diazepam** is highly **lipophilic** and extensively **protein-bound**, making it poorly amenable to removal by hemofiltration. *Charcoal* - **Activated charcoal** is used to prevent the absorption of ingested toxins from the gastrointestinal tract. - It is effective when administered soon after ingestion but does not reverse the established effects of an absorbed drug like diazepam in an overdose situation.
Question 6: Rules for criminal responsibility of the insane are all, except:
- A. American Law institute's rule
- B. Morrison's rule (Correct Answer)
- C. New Hampshire doctrine
- D. Durham Rule
Explanation: ***Morrison's rule*** - This is **not a recognized rule** or legal standard for determining criminal responsibility of the insane in any major legal system. - The other options represent established legal tests for **insanity defense**. *American Law Institute's rule* - Known as the **ALI Model Penal Code test** (1962), it states a person is not criminally responsible if they lack substantial capacity to appreciate the criminality of their conduct or to conform their conduct to the requirements of the law, due to mental disease or defect. - This rule is a common standard used in many **U.S. jurisdictions** and represents a middle ground between M'Naghten and Durham rules. *New Hampshire doctrine* - Also known as the **"New Hampshire Rule"** or **"Pike test"** from the 1870 case *State v. Pike*. - It introduced the concept that an accused is not criminally responsible if their unlawful act was the **product of mental disease or defect**. - This was the **precursor to the Durham Rule** and represented an early departure from the strict M'Naghten standard. *Durham Rule* - The **Durham Rule** (1954, *Durham v. United States*) is the **modern formulation of the product test**. - It states that an accused is not criminally responsible if their unlawful act was the **"product" of a mental disease or defect**. - Initially adopted in the **District of Columbia** but later abandoned in 1972 due to its broad and ambiguous nature, replaced by the ALI test.
Question 7: McNaughton's rule relates to?
- A. Medical negligence
- B. Criminal responsibility of insane (Correct Answer)
- C. Inquest
- D. Professional secrecy
Explanation: ***Criminal responsibility of insane*** - **McNaughton's rule** (also spelled M'Naghten rule) is a legal test for criminal insanity, stating that a defendant is not guilty by reason of insanity if, at the time of committing the act, they were suffering from a **defect of reason, from disease of the mind**, as not to know the nature and quality of the act they were doing, or if they did know it, that they did not know what they were doing was wrong. - This rule establishes the criteria for determining whether an individual's mental state at the time of a crime exempts them from **criminal responsibility**. *Medical negligence* - **Medical negligence** involves a healthcare professional's failure to provide care that meets the accepted standard, resulting in harm to a patient. - This concept is governed by principles such as the **Bolam test** or the **Bolitho test** in various jurisdictions, not McNaughton's rule. *Inquest* - An **inquest** is a judicial inquiry to ascertain the facts concerning an incident, especially a death, often conducted by a coroner. - It focuses on determining the **cause of death** and the circumstances surrounding it, not on the criminal responsibility of an accused. *Professional secrecy* - **Professional secrecy** (or confidentiality) refers to the ethical and legal obligation of professionals, including medical practitioners, to protect sensitive information shared by their clients or patients. - This principle is governed by **ethical codes** and **data protection laws**, not by McNaughton's rule.
Question 8: Provision of the Mental Health Act 2017, based on WHO guidelines, includes all, except:
- A. Social support
- B. Screening family members (Correct Answer)
- C. Human rights
- D. Communication regarding care and treatment
Explanation: ***Screening family members*** - The Mental Health Act 2017 focuses on the **rights, treatment, and support of individuals with mental illness**, not routine screening of their family members. - The Act does not contain provisions mandating **screening of asymptomatic family members**, though family history may be relevant for clinical assessment. - This is **not a provision** outlined in the Act based on WHO guidelines. *Human rights* - The Act is explicitly grounded in the **protection and promotion of human rights** for persons with mental illness (Chapter I). - Ensures care with **dignity, respect, and freedom from discrimination** as core principles. - Aligns with WHO's mental health action plan and human rights framework. *Communication regarding care and treatment* - **Section 4** emphasizes the right to information and **informed consent** for all treatment decisions. - Patients must receive clear communication about their **diagnosis, treatment options, and care plans**. - Includes provisions for **advance directives** and involvement in treatment decisions. *Social support* - **Chapter V** addresses rehabilitation and community-based services, emphasizing the role of **social support systems**. - Promotes **community integration** and access to social resources for recovery. - Recognizes family and community support as essential for long-term mental health management.
Question 9: A 45-year-old male with a history of chronic alcohol use is admitted to the hospital. He presents with anxiety, tremors, and agitation after his last drink 24 hours ago. Which of the following medications is most appropriate for controlling alcohol withdrawal symptoms?
- A. Lorazepam (Correct Answer)
- B. Fomepizole
- C. Disulfiram
- D. Buspirone
- E. Naltrexone
Explanation: ***Lorazepam*** - **Lorazepam**, a **benzodiazepine**, is the first-line treatment for alcohol withdrawal symptoms due to its ability to enhance **GABAergic activity**, which is deficient during withdrawal. - Its **intermediate half-life** and **lack of active metabolites** make it suitable for patients with liver impairment, common in chronic alcohol users. *Fomepizole* - **Fomepizole** is an antidote used to treat poisoning from **methanol** or **ethylene glycol**, not alcohol withdrawal. - It works by inhibiting **alcohol dehydrogenase**, an enzyme involved in the metabolism of these toxic alcohols. *Disulfiram* - **Disulfiram** is an **aldehyde dehydrogenase inhibitor** used to deter alcohol consumption in recovering alcoholics by causing unpleasant reactions if alcohol is consumed. - It is **not used to treat acute alcohol withdrawal symptoms** and can be dangerous if given during withdrawal due to potential interactions. *Buspirone* - **Buspirone** is an **anxiolytic** that acts as a **serotonin receptor agonist** and is used for generalized anxiety disorder. - It is **ineffective for acute alcohol withdrawal** due to its slow onset of action and lack of anticonvulsant properties. *Naltrexone* - **Naltrexone** is an **opioid receptor antagonist** used for relapse prevention and reducing alcohol craving in patients with alcohol use disorder. - It is **not effective for acute alcohol withdrawal symptoms** and does not prevent seizures or delirium tremens, which are life-threatening complications of withdrawal.
Question 10: Which of the following is false regarding parasuicide?
- A. Also known as attempted suicide.
- B. Mostly seen in psychological disturbances.
- C. A conscious, impulsive, manipulative act to get rid of an intolerable situation.
- D. Hanging is the most common form. (Correct Answer)
Explanation: **Explanation:** **Parasuicide** (also known as Deliberate Self-Harm) refers to a non-fatal act in which an individual deliberately causes self-injury or ingests a substance in excess of the prescribed dosage. **Why Option D is the correct answer (False statement):** Hanging is the most common method used in **completed suicides**, not parasuicide. In parasuicide, the intent is often not to die but to communicate distress or manipulate a situation. Therefore, the methods chosen are usually less lethal and allow for intervention. The most common method of parasuicide is **self-poisoning** (e.g., drug overdose or pesticide ingestion) or **superficial wrist cutting**. **Analysis of other options:** * **Option A:** Parasuicide is synonymous with **attempted suicide**, though the term is specifically used for acts where the intent to die is low or ambiguous. * **Option B:** It is frequently seen in individuals with **psychological disturbances**, most notably **Borderline Personality Disorder**, depression, and substance abuse. * **Option C:** It is often a **conscious and impulsive act**. It is frequently described as "manipulative" (or a "cry for help") because the goal is often to escape an intolerable emotional state or to influence the behavior of others. **High-Yield Clinical Pearls for NEET-PG:** * **Gender:** Parasuicide is more common in **females**, whereas completed suicide is more common in **males** (Gender Paradox). * **Age:** Most common in the younger age group (15–30 years). * **Strongest Predictor:** A previous history of parasuicide is the strongest predictor of a future completed suicide. * **SAD PERSONS Scale:** Used to assess the risk of suicide in clinical settings.
