NEET-PG 2012 - Psychiatry NEET-PG Practice Questions and MCQs
Question 1: What is the code for mental disorders in the ICD-10 classification?
- A. E
- B. F (Correct Answer)
- C. P
- D. G
Explanation: ***F*** - In the **ICD-10 classification**, the chapter for **Mental and behavioural disorders** is designated by the letter **'F'**. - This chapter covers a wide range of conditions, from mental retardation to mood disorders and substance-related disorders. *E* - The letter **'E'** in ICD-10 is used for **Endocrine, nutritional and metabolic diseases**. - This category includes conditions like diabetes mellitus and thyroid disorders. *P* - The letter **'P'** in ICD-10 denotes **Certain conditions originating in the perinatal period**. - These are conditions that arise during the period around childbirth. *G* - The letter **'G'** in ICD-10 refers to **Diseases of the nervous system**. - This chapter includes conditions like epilepsy, Parkinson's disease, and stroke.
Question 2: According to the classical monoamine hypothesis of depression, deficiency of which of the following neurotransmitters is MOST commonly emphasized in modern antidepressant therapy?
- A. Serotonin (Correct Answer)
- B. Acetylcholine
- C. Dopamine
- D. GABA
Explanation: ***Serotonin*** - The **classical monoamine hypothesis** of depression posits deficiencies in monoamine neurotransmitters including **serotonin (5-HT), norepinephrine, and dopamine**. - Among these, **serotonin** is the **most commonly emphasized** in modern antidepressant therapy, given its central role in mood regulation, sleep, appetite, and cognition. - The majority of first-line antidepressants, such as **SSRIs (Selective Serotonin Reuptake Inhibitors)** and **SNRIs**, primarily target serotonergic pathways, reflecting its clinical importance. - **Clinical relevance**: Serotonin deficiency is associated with depressed mood, anxiety, sleep disturbances, and appetite changes. *Acetylcholine* - **Acetylcholine** is a neurotransmitter involved in cognitive function, memory, and muscle contraction. - It is **not a monoamine** and is not part of the classical monoamine hypothesis of depression. - Acetylcholine deficiency is primarily implicated in **Alzheimer's disease** and other cognitive disorders, not depression. *Dopamine* - **Dopamine** is one of the three monoamines implicated in the classical hypothesis and plays a role in pleasure, reward, motivation, and motor control. - Dopamine deficiency can contribute to symptoms of **anhedonia** (inability to feel pleasure) and lack of motivation in depression. - However, dopamine-targeting antidepressants (like bupropion) are less commonly used as first-line therapy compared to serotonergic agents, making serotonin the most emphasized in clinical practice. *GABA* - **GABA (gamma-aminobutyric acid)** is the primary **inhibitory neurotransmitter** in the central nervous system. - It is **not a monoamine** and is not part of the classical monoamine hypothesis of depression. - GABA dysfunction is primarily associated with **anxiety disorders, seizures, and insomnia**, not depression as per the classical hypothesis.
Question 3: Muttering delirium is seen with: NEET 13
- A. Datura (Correct Answer)
- B. Castor oil plant
- C. Cocaine (stimulant)
- D. Monkshood (Aconitum)
Explanation: ***Datura*** - **Datura poisoning** is characterized by an **anticholinergic toxidrome**, which includes central nervous system effects like **muttering delirium, hallucinations**, and disorientation. - The patient exhibits features like **dilated pupils, dry mouth, flushed skin**, and **tachycardia** due to the blockage of muscarinic acetylcholine receptors. *Castor oil plant* - The **castor oil plant** contains **ricin**, a potent toxin that causes **gastrointestinal symptoms** (nausea, vomiting, abdominal pain, bloody diarrhea) and eventually multi-organ failure. - It does not typically cause the central nervous system effects like **muttering delirium** seen with Datura poisoning. *Cocaine (stimulant)* - **Cocaine** is a central nervous system stimulant that causes **euphoria, agitation, paranoia, dilated pupils**, and **tachycardia**. - While it can cause psychosis, the specific **muttering delirium** is not its hallmark presentation; instead, it is associated with a hyperadrenergic state. *Monkshood (Aconitum)* - **Monkshood** contains **aconitine**, a neurotoxin that primarily affects cardiac and neurological function, causing **paresthesias, muscle weakness, bradycardia**, and potentially fatal arrhythmias. - It does not typically cause the **muttering delirium** with features of an anticholinergic syndrome.
Question 4: What are the homes called where children are placed under the care of doctors and psychiatrists?
- A. Foster care homes
- B. Youth detention centers
- C. Child mental health clinics
- D. Residential treatment facilities (Correct Answer)
Explanation: ***Residential treatment facilities*** - These facilities provide structured, live-in therapeutic environments where children and adolescents receive comprehensive psychiatric and medical care. - They are staffed by a multidisciplinary team including **psychiatrists**, psychologists, social workers, and nurses. *Foster care homes* - Foster care involves placing children with temporary families, usually due to neglect or abuse, focusing on a family-like setting rather than intensive medical or psychiatric care. - While foster children may receive mental health services, the homes themselves are not clinical environments. *Youth detention centers* - These facilities are for children and adolescents who have committed crimes and are awaiting trial or serving sentences. - While mental health services may be provided, their primary purpose is correctional, not therapeutic. *Child mental health clinics* - These clinics offer outpatient services, including diagnosis, therapy, and medication management, but do not provide residential care. - Children attend appointments and then return home, unlike the live-in care provided in residential facilities.
Question 5: In the context of understanding patient behavior and therapeutic relationships, what is the definition of social psychology?
- A. The study of human relationships and behavior in social contexts
- B. The examination of cultural influences on behavior
- C. A field that does not exist
- D. The study of how individuals think, feel, and behave in social situations (Correct Answer)
Explanation: ***The study of how individuals think, feel, and behave in social situations*** - **Social psychology** focuses on understanding how individual thoughts, feelings, and behaviors are influenced by the actual, imagined, or implied presence of others. - This field examines topics like **social perception**, **attitude formation**, and **interpersonal relationships**, which are crucial for understanding therapeutic interactions. *The study of human relationships and behavior in social contexts* - While this option is close, it is a broader and less precise definition. Social psychology specifically focuses on the **individual's psychological processes** within social contexts. - This definition could also encompass fields like **sociology**, which studies groups and societies rather than the individual experience. *The examination of cultural influences on behavior* - This describes **cultural psychology** or **cross-cultural psychology**, which explicitly investigates the impact of culture on psychological processes. - While culture is a social context, social psychology's scope is broader, encompassing all forms of social influence, not just cultural ones. *A field that does not exist* - This statement is incorrect; **social psychology is a well-established and active field** within psychology. - It has a rich history and continues to contribute significantly to our understanding of human behavior and interactions.
Question 6: What is the most commonly abused drug in India?
- A. Heroin
- B. Amphetamine
- C. Cocaine
- D. Cannabis (Correct Answer)
Explanation: ***Cannabis*** - Cannabis (bhang, ganja, charas) is the **most commonly abused illicit drug in India** according to national surveys including the National Survey on Extent and Pattern of Substance Use. - It has **widespread social and cultural acceptance** in certain contexts, contributing to its higher prevalence across diverse populations. - Cannabis use is distributed across **all socioeconomic strata** and geographic regions, making it more prevalent than other illicit drugs. *Heroin* - While heroin is a **highly addictive opioid** with severe health consequences, its overall prevalence is **lower than cannabis** at the national level. - Heroin abuse is more concentrated in **specific regions** (northern states like Punjab, northeastern states) rather than being uniformly distributed. - The National Survey data shows opioid abuse (including heroin) affects a **smaller percentage** of the population compared to cannabis. *Amphetamine* - Amphetamines are **stimulant drugs** that are significantly less commonly abused in India compared to cannabis and opioids. - Their use is **highly localized** and represents a much smaller proportion of substance abuse cases. *Cocaine* - Cocaine is a **powerful stimulant** that is expensive and less accessible in India, making it one of the **least commonly abused** drugs. - Its use is typically limited to **affluent urban populations** and represents minimal prevalence in national substance abuse statistics.
Question 7: What term describes repetitive, intrusive thoughts that cause significant distress or anxiety?
- A. Phobia
- B. Obsession (Correct Answer)
- C. Compulsion
- D. Anxiety
Explanation: ***Obsession*** - An **obsession** is defined by the presence of **recurrent and persistent thoughts, urges, or images** that are experienced as intrusive and unwanted, causing significant anxiety or distress. - These thoughts are often recognized as products of one's own mind, and individuals typically attempt to ignore, suppress, or neutralize them. *Phobia* - A **phobia** is an intense, irrational fear of a specific object or situation that poses little or no actual danger. - Unlike obsessions, phobias are typically related to external stimuli and do not primarily involve intrusive thoughts. *Compulsion* - A **compulsion** is a repetitive behavior (e.g., hand washing, checking) or mental act (e.g., praying, counting) that an individual feels driven to perform in response to an obsession. - Compulsions are often aimed at preventing or reducing anxiety or distress, or preventing some dreaded event or situation. *Anxiety* - **Anxiety** is a general term for a feeling of worry, nervousness, or unease, typically about an event or something with an uncertain outcome. - While obsessions cause anxiety, "anxiety" itself is a broad emotional state, not specifically the intrusive thoughts described.
Question 8: Which of the following is a first-line treatment for bipolar affective (manic-depressive) disorder:
- A. Chlorpromazine
- B. Haloperidol
- C. Diazepam
- D. Lithium carbonate (Correct Answer)
Explanation: **Lithium carbonate** - **Lithium** is a well-established and highly effective **mood stabilizer**, considered a first-line treatment for managing both **manic** and **depressive episodes** in bipolar disorder. - It helps prevent recurrent episodes and reduces the severity of mood swings, acting as a prophylactic agent. *Chlorpromazine* - **Chlorpromazine** is a **first-generation antipsychotic** that is primarily used to treat **schizophrenia** and other psychotic disorders. - While it can be used acutely to manage severe manic agitation, it is not a first-line agent for the long-term mood stabilization characteristic of bipolar disorder. *Haloperidol* - **Haloperidol** is another **first-generation antipsychotic** often used for acute treatment of **psychotic symptoms** or severe agitation, including in mania. - It is not a primary long-term mood stabilizer for bipolar disorder due to its side effect profile and lack of efficacy in preventing future mood episodes compared to lithium. *Diazepam* - **Diazepam** is a **benzodiazepine** primarily used for treating **anxiety**, muscle spasms, and acute seizures. - While it can help manage acute agitation and insomnia during a manic episode, it does not have mood-stabilizing properties and is not a long-term treatment for bipolar disorder.
Question 9: Which of the following factors is most commonly associated with suicidal tendencies?
- A. Female gender
- B. Severe depression (Correct Answer)
- C. Chronic illness
- D. Younger age group
Explanation: ***Severe depression*** - **Major depressive disorder** is the strongest and most common risk factor for suicidal ideation and attempts, significantly increasing suicidal tendencies [1]. - The profound **hopelessness**, **worthlessness**, and altered cognitive processing associated with severe depression contribute largely to suicidal thoughts [2]. - Depression is present in approximately **90%** of individuals who die by suicide. *Female gender* - While **females** have higher rates of **suicide attempts** and self-harm, **males** have a higher rate of completed suicides using more lethal methods. - Female gender alone is not the most common risk factor for suicidal tendencies compared to the profound impact of severe mental illness like depression [1]. *Chronic illness* - **Chronic medical conditions** can increase the risk of depression and subsequent suicidal ideation due to pain, functional limitations, and loss of independence [3]. - However, chronic illness is generally considered an **indirect risk factor**, often mediating its effect through the development of mental health disorders like depression [3]. *Younger age group* - Suicide is a leading cause of death in **adolescents and young adults**, highlighting significant concern in this demographic [1]. - While younger age is a risk factor, especially with concurrent mental health issues or stressors, it is not as universally predictive of suicidal tendencies as severe depression across all age groups [1].
Question 10: Which of the following is not a characteristic of schizoid personality disorder?
- A. Prone to fantasy
- B. Introspective
- C. Aloof & detached
- D. Suspicious (Correct Answer)
Explanation: ***Suspicious*** - **Suspiciousness** and mistrust of others are core features of **paranoid personality disorder**, not schizoid personality disorder. - Individuals with schizoid personality disorder are typically apathetic towards others rather than actively distrustful. *Aloof & detached* - Individuals with schizoid personality disorder are characterized by a pervasive pattern of **detachment from social relationships** and a restricted range of emotional expression. - They often appear emotionally cold and indifferent to praise or criticism, indicating their aloof nature. *Prone to fantasy* - People with schizoid personality disorder frequently engage in **excessive daydreaming** and imaginative fantasy as an escape from reality. - This tendency is a coping mechanism for their limited social interaction and emotional expression. *Introspective* - Schizoid individuals tend to be **preoccupied with their inner world** and thoughts, often to the exclusion of external social interactions. - Their introspective nature contributes to their social withdrawal and isolation.
