Emergency Psychiatry Indian Medical PG Practice Questions and MCQs
Question 1: 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.
Question 2: A 20-year-old male with a known history of mental illness presented to the emergency room with aggressive behavior and a tendency to physically attack others. Following a psychiatric evaluation, he was prescribed new medications and his previous medication dosage was adjusted. Three days later, he returned to the emergency room with fever (105°F), stiff limbs, altered sensorium, and elevated serum CPK levels. What is the immediate management for this condition?
- A. Succinylcholine
- B. Dantrolene (Correct Answer)
- C. Edrophonium
- D. Neostigmine
Explanation: **Explanation:** The patient is presenting with the classic tetrad of **Neuroleptic Malignant Syndrome (NMS)**: hyperpyrexia (105°F), muscular "lead-pipe" rigidity, altered mental status, and autonomic instability, following the initiation or dose escalation of antipsychotics. The elevated serum Creatine Phosphokinase (CPK) confirms significant muscle necrosis due to intense rigidity. **1. Why Dantrolene is Correct:** NMS is a life-threatening emergency caused by central dopamine blockade. **Dantrolene** is a direct-acting skeletal muscle relaxant that inhibits the release of calcium from the sarcoplasmic reticulum. It is the drug of choice to treat the severe muscle rigidity and hyperthermia associated with NMS, thereby preventing further rhabdomyolysis and organ failure. **2. Why Incorrect Options are Wrong:** * **Succinylcholine:** A depolarizing neuromuscular blocker used in anesthesia. It is strictly contraindicated here as it can worsen hyperkalemia and potentially trigger Malignant Hyperthermia. * **Edrophonium:** A short-acting acetylcholinesterase inhibitor used in the Tensilon test to diagnose Myasthenia Gravis; it has no role in NMS. * **Neostigmine:** An acetylcholinesterase inhibitor used to treat Myasthenia Gravis or reverse non-depolarizing muscle relaxants; it does not address the pathophysiology of NMS. **Clinical Pearls for NEET-PG:** * **Mnemonic for NMS (FEVER):** **F**ever, **E**ncephalopathy, **V**itals unstable, **E**levated CPK/WBC, **R**igidity. * **First step in management:** Immediately stop the offending antipsychotic agent. * **Specific Pharmacotherapy:** **Dantrolene** (muscle relaxant) or **Bromocriptine/Amantadine** (Dopamine agonists). * **Differential Diagnosis:** Unlike Serotonin Syndrome, NMS is characterized by "lead-pipe" rigidity and bradyreflexia, whereas Serotonin Syndrome features hyperreflexia and myoclonus.
Question 3: A patient presents to the emergency department with self-harm and indicates suicidal intent. Which of the following conditions does not warrant an immediate specialist assessment?
- A. Formal thought disorder
- B. Acute alcohol intoxication (Correct Answer)
- C. Chronic severe physical illness
- D. Social isolation
Explanation: **Explanation:** The management of a suicidal patient in the emergency department involves identifying high-risk factors that necessitate immediate psychiatric intervention. **Why Option B is Correct:** **Acute alcohol intoxication** is a transient state that can significantly cloud a clinical assessment. Alcohol acts as a disinhibitor, often leading to impulsive self-harm threats that may resolve once the patient is sober. Standard clinical guidelines (such as those from NICE) suggest that a formal specialist psychiatric assessment should be deferred until the patient is sober, as the "true" underlying mental state and level of intent cannot be accurately determined while intoxicated. However, the patient must be kept in a safe environment until they are fit for assessment. **Why the other options are wrong:** * **A. Formal thought disorder:** This indicates a potential psychotic illness (like Schizophrenia). Psychosis is a major risk factor for "command hallucinations" or delusional thinking, which significantly increases the risk of completed suicide. * **C. Chronic severe physical illness:** Chronic pain or terminal illness (e.g., cancer, end-stage renal disease) are well-established independent risk factors for suicide due to hopelessness and a desire to end suffering. * **D. Social isolation:** Being single, widowed, or living alone (lack of social support) is a core demographic risk factor in suicide risk stratification (e.g., the SAD PERSONS scale). **High-Yield Clinical Pearls for NEET-PG:** * **SAD PERSONS Scale:** A mnemonic for suicide risk (Sex: Male, Age: <19 or >45, Depression, Previous attempt, Ethanol/Drug use, Rational thinking loss, Social support lacking, Organized plan, No spouse, Sickness). * **Most common method of completed suicide:** Hanging (India and globally). * **Most common method of attempted suicide:** Poisoning/Drug overdose. * **Strongest predictor of suicide:** A previous history of self-harm or suicide attempts.
Question 4: Suicidal tendencies are least common in which of the following demographic groups or conditions?
- A. Individuals who are alone
- B. Individuals with depression
- C. Males
- D. Married individuals (Correct Answer)
Explanation: **Explanation:** The risk of suicide is heavily influenced by socio-demographic factors and psychiatric comorbidities. According to **Durkheim’s theory of social integration**, individuals with strong social ties and support systems have a significantly lower risk of suicide. **Why Married Individuals is the Correct Answer:** Marriage acts as a major **protective factor** against suicide. It provides social integration, emotional support, and a sense of responsibility toward family members (especially if children are involved). Statistically, married individuals have the lowest rates of suicide compared to those who are single, divorced, widowed, or separated. **Analysis of Incorrect Options:** * **Individuals who are alone:** Social isolation is a high-risk factor. Living alone, being single, or experiencing recent bereavement increases the risk due to a lack of "social buffers." * **Individuals with depression:** Psychiatric illness is the strongest predictor of suicide. Approximately 15% of patients with severe Depressive Disorder eventually die by suicide. It is a state of high vulnerability. * **Males:** While females make more suicide *attempts*, **males are more likely to complete suicide** (the Gender Paradox). This is because men typically use more lethal methods (e.g., firearms, hanging). **High-Yield Clinical Pearls for NEET-PG:** * **Strongest Predictor:** A previous history of suicide attempts is the single best predictor of a future completed suicide. * **Age:** Risk generally increases with age; the elderly (especially males >65) are at very high risk. * **Employment:** Unemployment and financial instability are significant risk factors. * **Protective Factors:** Marriage, pregnancy (in women), and strong religious beliefs/affiliations.
Question 5: What is the most common cause of parasuicide?
- A. Drug ingestion (Correct Answer)
- B. Hanging
- C. Cutting wrist
- D. Firearms
Explanation: **Explanation:** **Parasuicide** (also known as non-suicidal self-injury or deliberate self-harm) refers to an act in which an individual mimics a suicide attempt but without a true fatal intent. The primary goal is often a "cry for help" or an expression of emotional distress rather than death. **Why Drug Ingestion is Correct:** **Drug ingestion (overdose)** is the most common method of parasuicide globally. It is preferred because it is relatively painless, less disfiguring, and allows for a "window of rescue." Common agents include benzodiazepines, analgesics (paracetamol), and antidepressants. In the Indian context, organophosphate poisoning is also frequently seen in rural areas. **Analysis of Incorrect Options:** * **B. Hanging:** This is the **most common method of completed suicide** in India. It is highly lethal and offers little chance of intervention once the act is initiated, making it rare in parasuicide. * **C. Cutting wrist:** While a common method of self-harm (especially in Borderline Personality Disorder), it ranks second to drug ingestion in overall frequency for parasuicide. * **D. Firearms:** This is a highly violent and lethal method. It is rarely used in parasuicide due to its high fatality rate and limited accessibility in the Indian subcontinent. **High-Yield Clinical Pearls for NEET-PG:** * **Most common method of Completed Suicide:** Hanging (India); Firearms (USA). * **Gender Paradox:** Suicide is more common in **males**, but parasuicide (self-harm) is significantly more common in **females**. * **Strongest Predictor:** A previous history of parasuicide/self-harm is the strongest predictor of a future completed suicide. * **Risk Factor:** Depression is the most common psychiatric illness associated with suicide.
Question 6: Laryngeal dystonia, which is a psychiatric emergency, can be treated with?
- A. lorazepam (Correct Answer)
- B. milnacipran
- C. dantrolene
- D. propanolol
Explanation: ### Explanation **Laryngeal dystonia** is a life-threatening form of **Acute Dystonia**, a common Extrapyramidal Side Effect (EPS) occurring within hours to days of starting high-potency antipsychotics (e.g., Haloperidol). It involves involuntary spasms of the laryngeal muscles, leading to airway obstruction, stridor, and potential asphyxiation, making it a true psychiatric emergency. **Why Lorazepam is the correct answer:** The first-line treatment for acute dystonia is typically parenteral anticholinergics (like Benztropine or Promethazine). However, when these are unavailable or when rapid muscle relaxation is required in an emergency setting, **intravenous Benzodiazepines (like Lorazepam or Diazepam)** are highly effective. They act by enhancing GABAergic inhibition, which helps counteract the dopamine-acetylcholine imbalance in the nigrostriatal pathway causing the spasm. **Analysis of Incorrect Options:** * **B. Milnacipran:** This is an SNRI (Serotonin-Norepinephrine Reuptake Inhibitor) used for depression and fibromyalgia; it has no role in treating EPS. * **C. Dantrolene:** This is a peripherally acting muscle relaxant used specifically for **Neuroleptic Malignant Syndrome (NMS)** and Malignant Hyperthermia. It is not the treatment for acute dystonia. * **D. Propranolol:** This beta-blocker is the drug of choice for **Akathisia** (subjective restlessness), another form of EPS, but it is ineffective for dystonia. **High-Yield Clinical Pearls for NEET-PG:** * **Risk Factors:** Young males and those receiving high-potency first-generation antipsychotics are at the highest risk. * **Order of EPS onset:** Dystonia (hours) → Akathisia (days) → Parkinsonism (weeks) → Tardive Dyskinesia (months/years). * **Drug of Choice (General Dystonia):** Injection **Promethazine** or Benztropine. * **Oculogyric Crisis:** Another common presentation of acute dystonia involving involuntary upward deviation of the eyes.
Question 7: Which of the following is a common cause of delirium?
- A. Infection (Correct Answer)
- B. Liver failure
- C. Belladonna poisoning
- D. None of the above
Explanation: **Explanation:** Delirium is an acute, transient, and reversible syndrome characterized by a disturbance in consciousness, attention, and cognition. It is always secondary to an underlying medical condition, substance intoxication, or withdrawal. **1. Why Infection is the Correct Answer:** Infections (especially **Urinary Tract Infections (UTIs)** in the elderly and **Pneumonia**) are the most common systemic causes of delirium. The pathophysiology involves the release of pro-inflammatory cytokines that cross the blood-brain barrier, leading to neuroinflammation and neurotransmitter imbalances (primarily cholinergic deficiency and dopaminergic excess). **2. Analysis of Incorrect Options:** * **B. Liver Failure:** While hepatic encephalopathy is a known cause of delirium, it is categorized as a metabolic cause. Statistically, systemic infections are more frequent triggers in a general clinical setting. * **C. Belladonna Poisoning:** This causes anticholinergic toxicity. While it presents with "delirium-like" symptoms (the "mad as a hatter" mnemonic), it is a specific toxicological cause rather than the most common general cause. * **D. None of the above:** Incorrect, as infection is a primary etiology. **High-Yield Clinical Pearls for NEET-PG:** * **Core Feature:** Clouding of consciousness (altered sensorium) with a fluctuating course (worse at night, known as "sundowning"). * **EEG Finding:** Characterized by **generalized slowing** of background activity (except in Alcohol Withdrawal/Delirium Tremens, where there is low-amplitude fast activity). * **Visual Hallucinations:** These are the most common type of hallucinations in delirium. * **Management:** The priority is treating the **underlying cause** (e.g., antibiotics for infection). Low-dose Haloperidol is the drug of choice for symptomatic agitation (avoid benzodiazepines unless it is alcohol withdrawal).
Question 8: A patient presents to the emergency department with self-harm and indicates suicidal intent. Which of the following conditions does not warrant an immediate specialist assessment?
- A. Formal thought disorder
- B. Acute alcohol intoxication (Correct Answer)
- C. Chronic severe physical illness
- D. Social isolation
Explanation: **Explanation:** In emergency psychiatry, the decision to refer for an immediate specialist assessment (Psychiatrist) is based on the presence of high-risk factors for completed suicide or the presence of a comorbid psychiatric illness that impairs judgment. **Why Option B is Correct:** **Acute alcohol intoxication** is a transient state. Alcohol significantly impairs judgment and increases impulsivity, often leading to "reactive" self-harm. Clinical guidelines (such as NICE) suggest that a formal psychiatric assessment is often inaccurate and unreliable while a patient is intoxicated. The priority is medical stabilization and observation until the patient is sober. Once the effects of alcohol have worn off, the patient should be reassessed; if the suicidal intent persists, a specialist referral is then indicated. **Why the other options are incorrect:** * **A. Formal thought disorder:** This indicates a likely diagnosis of Schizophrenia or Psychosis. Command hallucinations or delusional thinking significantly increase the risk of unpredictable and lethal self-harm, requiring immediate specialist intervention. * **C. Chronic severe physical illness:** Chronic pain or terminal illness (e.g., cancer, ESRD) are well-established independent risk factors for suicide. These patients often have a high degree of "intent" and "planning," necessitating urgent assessment. * **D. Social isolation:** Living alone, being widowed, or lacking a support system are major demographic risk factors (SAD PERSONS scale). Lack of social "buffers" increases the likelihood of a completed suicide attempt. **High-Yield Clinical Pearls for NEET-PG:** * **SAD PERSONS Scale:** Used to assess suicide risk (Sex, Age, Depression, Previous attempt, Ethanol, Rational thought loss, Social support lack, Organized plan, No spouse, Sickness). * **Most common method of suicide in India:** Hanging (followed by poisoning). * **Single most important predictor of suicide:** A previous history of self-harm/suicide attempts. * **Gender Paradox:** Women attempt suicide more frequently, but men complete suicide more often (due to more lethal methods).
Question 9: A patient presents to the emergency department with self-harm and indicates suicidal intent. Which of the following conditions does not warrant an immediate specialist assessment?
- A. Formal thought disorder
- B. Acute alcohol intoxication (Correct Answer)
- C. Chronic severe physical illness
- D. Social isolation
Explanation: **Explanation:** In emergency psychiatry, the goal of triage is to identify patients at the highest risk of completed suicide or those with underlying psychiatric pathology requiring immediate intervention. **Why Option B is Correct:** **Acute alcohol intoxication** is a transient state that can significantly cloud a patient's clinical picture, often causing "impulsive" suicidal ideation that may resolve as the patient sobers up. Standard clinical guidelines (such as those from NICE) suggest that a formal specialist psychiatric assessment is often **not reliable or warranted** until the effects of intoxication have worn off. The patient should be kept in a safe environment and reassessed once sober to determine if the suicidal intent persists. **Why the other options are wrong:** * **A. Formal thought disorder:** This indicates a likely diagnosis of Schizophrenia or Psychosis. Patients with psychosis are at high risk due to command hallucinations or delusional thinking, necessitating immediate specialist care. * **C. Chronic severe physical illness:** This is a well-established independent risk factor for suicide (especially in the elderly). Pain, loss of autonomy, and poor prognosis increase the lethality of intent. * **D. Social isolation:** Living alone or lacking a support system is a major sociodemographic risk factor. Without a "safety net," these patients are at a much higher risk of completing suicide if discharged. **High-Yield Clinical Pearls for NEET-PG:** * **SAD PERSONS Scale:** A mnemonic to remember suicide risk factors (Sex: Male, Age: <19 or >45, Depression, Previous attempt, Ethanol/Drug use, Rational thinking loss, Social support lacking, Organized plan, No spouse, Sickness). * **The single strongest predictor** of a completed suicide is a **previous history of self-harm/suicide attempts**. * **Demographics:** While women attempt suicide more frequently, men are more likely to complete it (due to more lethal methods).
Question 10: Which of the following is not used in the management of delirium?
- A. Haloperidol
- B. Lithium (Correct Answer)
- C. Diazepam
- D. Olanzapine
Explanation: ### Explanation **Delirium** is an acute, fluctuating syndrome of altered consciousness and cognitive dysfunction, usually secondary to an underlying medical condition. The primary management involves treating the underlying cause and managing behavioral symptoms. **Why Lithium is the Correct Answer:** **Lithium** is a mood stabilizer used primarily for Bipolar Disorder. It is **not** used in delirium for several reasons: 1. **Neurotoxicity:** Lithium has a narrow therapeutic index and can worsen confusion or cause "Lithium-induced delirium." 2. **Renal/Electrolyte Sensitivity:** Delirious patients are often dehydrated or have electrolyte imbalances, which significantly increases the risk of Lithium toxicity. 3. **Onset:** It takes days to reach a steady state, making it useless for acute behavioral emergencies. **Analysis of Other Options:** * **Haloperidol (Option A):** The traditional **drug of choice** for delirium. It has minimal respiratory depression and few anticholinergic side effects, making it safe for elderly or medically ill patients. * **Diazepam (Option B):** While benzodiazepines can worsen delirium in most cases (due to paradoxical agitation), they are the **first-line treatment for delirium tremens** (Alcohol Withdrawal Delirium) and sedative-hypnotic withdrawal. * **Olanzapine (Option D):** An atypical antipsychotic often used as an alternative to Haloperidol. It is effective for agitation and has a lower risk of Extrapyramidal Symptoms (EPS). **High-Yield Clinical Pearls for NEET-PG:** * **DOC for Delirium:** Haloperidol (low dose). * **DOC for Alcohol Withdrawal Delirium:** Benzodiazepines (e.g., Diazepam, Lorazepam). * **Avoid:** Drugs with strong anticholinergic properties (e.g., Chlorpromazine, Amitriptyline) as they worsen delirium. * **Non-pharmacological management:** Reorientation, adequate lighting, and correcting sleep-wake cycles are essential first steps.
Question 11: A 22-year-old male presented with a 2-day history of auditory hallucinations (hearing voices when no one is around) and aggressive behavior. He also reports that people are abusing him. He has had a fever for the past 2 days. There is no significant past medical history. What is the most likely diagnosis?
- A. Dementia
- B. Acute psychosis (Correct Answer)
- C. Delirium
- D. Delusion
Explanation: **Explanation:** The patient presents with a classic triad of **positive psychotic symptoms**: auditory hallucinations (perception without stimulus), persecutory ideas (people abusing him), and behavioral disturbances (aggression). The acute onset (2 days) and young age (22 years) point directly toward **Acute Psychosis**. **Why Acute Psychosis is correct:** In psychiatry, an acute onset of hallucinations and delusions in a young individual, lasting less than one month, is classified under Acute and Transient Psychotic Disorder (ICD-10) or Brief Psychotic Disorder (DSM-5). While the patient has a fever, the primary presentation is dominated by clear psychotic features. In NEET-PG scenarios, unless there is a documented clouding of consciousness or disorientation, these symptoms are treated as a psychiatric emergency. **Why other options are incorrect:** * **Delirium:** Although the patient has a fever, delirium is characterized by a **clouding of consciousness**, fluctuating levels of awareness, and disorientation to time, place, and person. The question does not mention cognitive impairment or altered sensorium. * **Dementia:** This is a chronic, progressive neurodegenerative condition (usually in the elderly) involving memory loss and cognitive decline. A 2-day history in a 22-year-old rules this out. * **Delusion:** This is a *symptom* (a fixed false belief), not a diagnosis. While the patient has delusional ideas, "Acute Psychosis" is the more comprehensive clinical diagnosis. **Clinical Pearls for NEET-PG:** * **Brief Psychotic Disorder:** Symptoms last >1 day but <1 month, with a full return to premorbid functioning. * **Schizophreniform Disorder:** Symptoms last 1–6 months. * **Schizophrenia:** Symptoms must persist for >6 months (DSM-5). * **Organic Psychosis:** Always rule out medical causes (like CNS infections or metabolic issues) when fever and psychosis coexist, but choose the psychiatric label if consciousness is intact.
Question 12: A 25-year-old uncooperative patient of schizophrenia was brought in to the casualty. The Casualty Medical Officer gave an injectable drug to the patient. Two hours later patient develops the following posturing. What is the best treatment?
- A. Propranolol
- B. Dantrolene sodium
- C. Ventriculostomy
- D. Benzhexol (Correct Answer)
Explanation: ***Benzhexol*** - The patient's posturing (likely **acute dystonia**) is a common extrapyramidal side effect of typical antipsychotics, which are often given via injection to uncooperative schizophrenic patients. - **Benzhexol** (trihexyphenidyl) is an anticholinergic medication used to treat drug-induced extrapyramidal symptoms like dystonia, parkinsonism, and akathisia. - In acute dystonia, **parenteral anticholinergics** (IV diphenhydramine or IM benztropine) are typically preferred for faster onset, but benzhexol remains a valid anticholinergic treatment option. - The anticholinergic action reverses the dystonic reaction by restoring the dopamine-acetylcholine balance in the basal ganglia. *Propranolol* - **Propranolol** is a beta-blocker primarily used to treat essential tremor and some forms of drug-induced akathisia, but it is not the first-line treatment for acute dystonia. - While it can help with anxiety symptoms associated with akathisia, it has no role in managing acute dystonic reactions. *Dantrolene sodium* - **Dantrolene sodium** is a direct-acting skeletal muscle relaxant primarily used in the management of **neuroleptic malignant syndrome (NMS)** and malignant hyperthermia. - NMS is a more severe and distinct adverse reaction, involving fever, muscle rigidity, altered mental status, and autonomic dysfunction, which is not depicted here. - Acute dystonia presents much earlier (hours) compared to NMS (days to weeks) and lacks the systemic features of NMS. *Ventriculostomy* - **Ventriculostomy** is a neurosurgical procedure to relieve hydrocephalus by draining cerebrospinal fluid from the ventricles of the brain. - This procedure is entirely unrelated to the management of drug-induced extrapyramidal side effects from antipsychotic medication.
Question 13: A psychiatrist receives a call from a patient who expresses thoughts of harming his ex-girlfriend. The patient describes a detailed plan to attack her at her workplace. Which of the following represents the psychiatrist's most appropriate legal obligation?
- A. Warn the ex-girlfriend and notify law enforcement (Correct Answer)
- B. Only notify the patient's family
- C. Warn only law enforcement
- D. Maintain patient confidentiality
Explanation: ***Warn the ex-girlfriend and notify law enforcement*** - This scenario directly triggers the **"duty to warn"** and **"duty to protect"** principles, primarily stemming from the **Tarasoff v. Regents of the University of California** case. - The psychiatrist has a legal obligation to take reasonable steps to protect the identifiable victim, which includes directly warning the intended victim and informing law enforcement. *Only notify the patient's family* - Notifying the patient's family alone does not fulfill the **legal obligation to protect** an identifiable third party from a serious threat of harm. - While family involvement might be part of a comprehensive safety plan, it is insufficient as the sole action in this critical situation. *Warn only law enforcement* - While notifying law enforcement is a crucial step, the **Tarasoff duty** specifically mandates warning the **intended victim** directly (or those who can reasonably be expected to notify the victim). - Relying solely on law enforcement might not ensure the immediate safety of the ex-girlfriend, especially if there's a delay in their response or ability to locate her. *Maintain patient confidentiality* - Patient confidentiality is a cornerstone of psychiatric practice, but it is **not absolute** when there is a serious and imminent threat of harm to an identifiable individual. - The **duty to protect** a potential victim *outweighs* the duty to maintain confidentiality in such extreme circumstances.
Question 14: Management of a violent patient in psychiatry includes all except:
- A. CBT (Correct Answer)
- B. Haloperidol
- C. ECT
- D. BZD
Explanation: ***CBT*** - **Cognitive Behavioral Therapy (CBT)** is a long-term psychological intervention aimed at changing maladaptive thought patterns and behaviors. It is **not suitable for immediate management** of an acutely violent patient. - While CBT can be beneficial for aggression management in a stable patient, it requires patient cooperation, cognitive engagement, and time, which are not available during a **violent psychiatric emergency**. *Haloperidol* - **Haloperidol** is a potent typical antipsychotic frequently used in acute settings for rapid tranquilization of violent or severely agitated patients. - It is effective in reducing **psychosis-related agitation** and can be administered **intramuscularly** for quick onset of action. - Often used in combination with benzodiazepines for optimal control of acute violence. *ECT* - **Electroconvulsive Therapy (ECT)** may be considered in **severe, treatment-resistant cases** of violence associated with conditions like uncontrolled mania, catatonic excitement, or psychotic depression when pharmacological interventions have failed. - While not used for immediate acute management due to logistical requirements (consent, anesthesia, specialized setup), it can be an effective option for severe psychiatric conditions with persistent violence. - It works by inducing a brief controlled seizure, which can rapidly alleviate severe symptoms. *BZD* - **Benzodiazepines (BZDs)** like lorazepam or diazepam are **first-line agents** in the acute management of violent or agitated patients due to their rapid anxiolytic, sedative, and muscle relaxant properties. - They are particularly useful for **calming acute agitation** and are often combined with antipsychotics for rapid tranquilization. - Can be administered intramuscularly or intravenously for quick action in psychiatric emergencies.
Question 15: Visual hallucinations are most commonly seen in:
- A. OCD
- B. Delusional syndrome
- C. Delirium (Correct Answer)
- D. Mania
Explanation: ***Delirium*** - **Visual hallucinations** are a hallmark symptom of **delirium**, often described as vivid and fluctuating. - Delirium presents with acute onset of **waxing and waning consciousness**, attention deficits, and cognitive impairment. *OCD* - **Obsessive-compulsive disorder** (OCD) is characterized by recurrent, intrusive thoughts (**obsessions**) and repetitive behaviors (**compulsions**). - It does not typically involve hallucinations; rather, individuals are usually aware of the irrationality of their obsessions and compulsions. *Delusional syndrome* - **Delusional disorders** primarily involve fixed, false beliefs (**delusions**) that are not bizarre and are not accompanied by prominent hallucinations. - While hallucinations can occur, they are generally not the most prominent or characteristic feature, unlike in delirium or psychotic disorders. *Mania* - **Mania**, a mood disorder, is characterized by an elevated, expansive, or irritable mood, increased activity, racing thoughts, and decreased need for sleep. - While psychotic features such as delusions (often grandiose) can occur in severe mania, **visual hallucinations** are less common than in delirium and audio hallucinations are more likely if present.
Question 16: What is the correct sequence of disorientation experienced by a person after a traumatic head injury?
- A. First place, then time, followed by person.
- B. First person, then time, followed by place.
- C. First time, then person, followed by place.
- D. First time, then place, followed by person. (Correct Answer)
Explanation: ***Correct: First time, then place, followed by person.*** - Disorientation to **time** is typically the first sign because it requires continuous updating of transient information, making it the most vulnerable to brain injury. - Disorientation to **place** usually follows, indicating difficulty in processing and remembering current environmental context. - Disorientation to **person** (self) is generally the last to occur, as personal identity is the most deeply ingrained and stable aspect of orientation. - This sequence (Time → Place → Person) is the classic pattern in traumatic head injury and cognitive impairment. *Incorrect: First place, then time, followed by person.* - Disorientation to **place** typically comes after disorientation to time, as spatial awareness is generally more stable than temporal awareness. - This sequence is not the commonly observed pattern in traumatic head injury where **time** is usually lost first. *Incorrect: First person, then time, followed by place.* - Disorientation to **person** (self) is generally the last to occur, not the first, as personal identity is the most deeply ingrained and stable aspect of orientation. - This sequence incorrectly places **person** at the beginning of the progression. *Incorrect: First time, then person, followed by place.* - While disorientation to **time** is correctly identified as first, disorientation to **person** typically occurs much later than disorientation to **place**. - This sequence does not align with the typical progression: Time → Place → Person.
Question 17: Delirium is defined as?
- A. Acute onset of disturbed consciousness (Correct Answer)
- B. Chronic onset of disturbed consciousness
- C. Progressive generalized impairment of intellectual functions and memory without impairment of consciousness
- D. Disorientation without clouding of consciousness
Explanation: ***Acute onset of disturbed consciousness*** - **Delirium** is characterized by an **acute or subacute onset** of fluctuating attention and cognition, indicating a rapid change from baseline mental status. - The core feature is a **disturbance in attention** and **awareness (consciousness)**, which can manifest as reduced clarity, disorientation, or an inability to focus. *Chronic onset of disturbed consciousness* - **Delirium** is by definition an **acute condition**, not chronic. Chronic conditions affecting consciousness tend to be more stable or progressively worsening over a longer period. - **Chronic disturbances** in consciousness are more indicative of conditions like persistent vegetative state or severe dementia, which have different diagnostic criteria than delirium. *Progressive generalized impairment of intellectual functions and memory without impairment of consciousness* - This description is characteristic of **dementia**, where there is a **gradual decline** in cognitive function (memory, intellect) without the primary disturbance of consciousness seen in delirium. - In **dementia**, alertness is generally preserved, while **delirium** involves a direct impairment of the ability to focus, sustain, or shift attention. *Disorientation without clouding of consciousness* - While **disorientation** can be a feature of delirium, it is not the sole defining characteristic and often occurs in conjunction with **clouding of consciousness** (impaired awareness and attention). - Isolated disorientation without other signs of disturbed consciousness might be seen in other conditions but is not sufficient for a diagnosis of **delirium**.
Question 18: The Confusion Assessment Method (CAM) is used for which of the following?
- A. Schizophrenia
- B. Delirium (Correct Answer)
- C. Dementia
- D. Depression
Explanation: ***Delirium*** - The Confusion Assessment Method (CAM) is a widely used and highly sensitive and specific tool for the rapid identification of **delirium**. - It assesses for acute onset and fluctuating course, inattention, disorganized thinking, and altered level of consciousness. *Schizophrenia* - Schizophrenia is a chronic mental health disorder primarily characterized by **psychosis**, including hallucinations, delusions, and disorganized thought. - While patients with schizophrenia can experience cognitive difficulties, specialized scales like the Positive and Negative Syndrome Scale (PANSS) are used, not the CAM. *Dementia* - Dementia is a gradual and progressive decline in cognitive function, including memory, thinking, and reasoning, severe enough to interfere with daily life. - Tools like the mini-mental state examination (MMSE) or Montreal Cognitive Assessment (MoCA) are used for screening and assessing dementia, not the CAM. *Depression* - Depression is a mood disorder characterized by persistent sadness, loss of interest, and other emotional and physical symptoms. - Assessment tools like the Hamilton Depression Rating Scale (HDRS) or Patient Health Questionnaire-9 (PHQ-9) are used for depression.
Question 19: Which of the following can cause delirium?
- A. Hypoxia
- B. Barbiturates
- C. Alcohol withdrawal
- D. All of the options (Correct Answer)
Explanation: ***All of the options*** - **Delirium** is an acute, fluctuating disturbance in attention and cognition, often with altered consciousness, and can be caused by a wide range of factors. - **Hypoxia**, **barbiturate** use, and **alcohol withdrawal** are all well-established causes of delirium. *Hypoxia* - **Cerebral hypoxia**, or insufficient oxygen supply to the brain, directly impairs neuronal function, leading to acute confusion and altered mental status characteristic of delirium. - Conditions like severe respiratory failure, heart failure, or anemia can precipitate hypoxia and subsequent delirium. *Barbiturates* - **Barbiturates** are central nervous system depressants that can cause sedation, confusion, and cognitive impairment, especially in overdose or in susceptible individuals. - While they typically induce sedation, paradoxical excitement or severe cognitive dysfunction consistent with delirium can occur. *Alcohol withdrawal* - **Alcohol withdrawal** can lead to a severe form of delirium known as *delirium tremens*, characterized by extreme confusion, hallucinations, tremors, and autonomic instability. - The rapid cessation of chronic alcohol intake disrupts neurochemical balance, leading to hyperexcitability and delirium.
Question 20: In which of the following psychiatric conditions is floccillation seen?
- A. Mania
- B. Depression
- C. Anxiety disorders
- D. Delirium (Correct Answer)
Explanation: ***Delirium*** - **Floccillation**, or carphologia, is specifically characterized by **purposeless plucking at bedclothes or imaginary objects**, indicative of severe agitation and altered consciousness. - It is a classic sign of **severe delirium**, often seen in critically ill, elderly, or demented patients. *Mania* - Mania presents with elevated mood, increased energy, and racing thoughts, but typically does not involve the disoriented, purposeless movements characteristic of floccillation. - While extreme agitation can occur in mania, it is usually goal-directed or related to the patient's grandiosity or irritability. *Depression* - Depression is characterized by low mood, anhedonia, and psychomotor retardation or agitation, but not by picking at bedclothes. - Psychomotor agitation in depression usually involves pacing or restless movements associated with distress, rather than the disoriented floccillation. *Anxiety disorders* - Anxiety disorders involve excessive worry and fear, with symptoms like restlessness, tension, and hypervigilance. - While patients can be agitated, they generally maintain awareness of their surroundings and typically do not exhibit meaningless motor behaviors like floccillation.
