Medical Clearance in Psychiatric Emergencies Indian Medical PG Practice Questions and MCQs
Question 1: Which of the following will have an organic cause?
- A. Schizophrenia
- B. Delirium (Correct Answer)
- C. Anxiety
- D. Obsessive compulsive disorder
Explanation: ***Delirium*** - Delirium is an **acute, fluctuating disturbance of consciousness** and cognition that is directly caused by a **medical condition**, substance intoxication/withdrawal, or medication side effect [1], [2], [3]. - It always has an **underlying organic etiology** such as infection, metabolic derangements, drug toxicity, or neurological disorders [1], [2]. *Schizophrenia* - Schizophrenia is a **chronic psychiatric disorder** characterized by psychosis (hallucinations, delusions), disorganized thinking, and negative symptoms. - While it has a neurobiological basis, it is considered a **primary mental illness** and not typically caused by an acute, identifiable organic illness in the way delirium is. *Anxiety* - Anxiety disorders are characterized by excessive worry, fear, and physical symptoms of arousal. They are considered **primary mental health conditions**. - Although stress can precipitate anxiety, it is not primarily due to a **specific acute organic cause** that resolves with treatment of that cause. *Obsessive compulsive disorder* - Obsessive-compulsive disorder (OCD) is an anxiety-related disorder characterized by **recurrent, intrusive thoughts (obsessions)** and repetitive behaviors (compulsions) aimed at reducing distress. - Like other primary mental health conditions, it has a neurobiological basis but is not classified as having an **acute organic cause** in the medical sense.
Question 2: ICD-10 chapter 1 describes?
- A. Poisoning and consequences
- B. Psychiatric diseases
- C. Diseases of the nervous system
- D. Infectious and parasitic diseases (Correct Answer)
Explanation: ***Infectious and parasitic diseases*** - **ICD-10 Chapter 1** specifically categorizes codes related to **infectious and parasitic diseases**, ranging from A00 to B99. - This chapter covers a broad spectrum of conditions caused by microorganisms and parasites, such as bacterial, viral, fungal, and protozoal infections. *Poisoning and consequences* - **Poisoning and certain other consequences of external causes** are covered in ICD-10 Chapter 19, with codes typically ranging from T36-T65 for poisoning by drugs, medicaments, and biological substances. - This chapter focuses on injuries, poisoning, and certain other consequences of external causes, not infectious diseases. *Psychiatric diseases* - **Mental and behavioral disorders** (often referred to as psychiatric diseases) are described in ICD-10 Chapter 5, with codes ranging from F00 to F99. - This chapter includes conditions such as mood disorders, anxiety disorders, schizophrenia, and substance-related disorders. *Diseases of the nervous system* - **Diseases of the nervous system** are categorized in ICD-10 Chapter 6, with codes ranging from G00 to G99. - This chapter covers conditions affecting the brain, spinal cord, nerves, and neuromuscular junctions, such as stroke, epilepsy, and Parkinson's disease.
Question 3: A person with unsound mind can be released with pending investigation or trial under:-
- A. Section 84 Cr P C
- B. Section 328 Cr P C
- C. Section 330 Cr P C (Correct Answer)
- D. Section 84 IPC
Explanation: ***Section 330 Cr P C*** - This section specifically deals with the power of the Court to **release a person with unsound mind** (or other mental incapacitation) pending investigation or trial. - It allows for the release of such individuals on **sufficient security** being given that they will be properly taken care of and produced in Court when required. *Section 84 Cr P C* - **Section 84 CrPC** does not deal with the release of persons with unsound mind. - This option is a distractor that may confuse candidates with Section 84 IPC or other provisions. *Section 328 Cr P C* - This section deals with the **procedure** when an accused appears to be of unsound mind during an inquiry or trial before a Magistrate. - It focuses on stopping the proceedings and determining the accused's mental state, not directly on release pending investigation or trial. *Section 84 IPC* - This section of the Indian Penal Code (IPC) addresses the **acts of a person of unsound mind** and provides a defense against criminal liability. - It applies to the substantive criminal law regarding culpability, not the procedural aspects of release during investigation or trial.
Question 4: A female patient has been on lithium for bipolar disorder for 6 months. After fasting for several days due to religious reasons, she presents with seizures, tremors, confusion, and weakness. What is the most appropriate investigation to diagnose her condition?
- A. Serum electrolytes
- B. Serum lithium levels (Correct Answer)
- C. ECG
- D. MRI
Explanation: **Serum lithium levels** - The patient's symptoms (seizures, tremors, confusion, weakness) are classic for **lithium toxicity**. - **Fasting** can lead to dehydration and electrolyte imbalance, which can increase lithium concentrations and toxicity [1]. *Serum electrolytes* - While **electrolyte imbalances** can occur with fasting and contribute to symptoms, measuring serum electrolytes alone will not directly diagnose lithium toxicity. - Electrolyte disturbances might be a predisposing factor or a concomitant issue, but not the primary diagnostic test for lithium toxicity itself [1]. *ECG* - An **ECG** can reveal cardiac effects of lithium toxicity, such as T-wave flattening or inversion, but it is not the most appropriate direct diagnostic test for the condition itself. - ECG changes are secondary manifestations and may not always be present or specific. *MRI* - While an **MRI** of the brain might be considered to rule out other causes of neurological symptoms like a stroke or brain lesion, it is not the initial or most appropriate investigation for suspected lithium toxicity. - The clinical picture strongly points to a pharmacological cause, making laboratory tests more relevant first-line diagnostics than imaging.
Question 5: All of the following are components of the mental status examination EXCEPT:
- A. Insight
- B. Delirium (Correct Answer)
- C. Affect
- D. Judgment
Explanation: **Delirium** - **Delirium** itself is an **acute neuropsychiatric syndrome** characterized by a disturbance in attention and awareness, and it is a *diagnosis* or a *syndrome* that might be suggested by findings on a mental status examination, rather than a component *of* the examination. - The mental status examination *assesses for signs* of delirium (e.g., inattention, disorganized thinking), but "delirium" is not a specific domain assessed like affect or insight. *Insight* - **Insight** is a key component of the mental status examination, referring to the patient's **understanding of their own mental illness** or situation. - It assesses their awareness of symptoms, the belief in the need for treatment, and the recognition of the illness's impact. *Affect* - **Affect** is a component of the mental status examination that describes the **observable expression of emotion**, such as facial expressions, tone of voice, and body language. - It is distinct from mood, which is the patient's subjective emotional state, and helps in evaluating emotional regulation. *Judgment* - **Judgment** is a component of the mental status examination that assesses the patient's ability to make **sound decisions** and understand the likely consequences of their behavior. - This is often evaluated through hypothetical scenarios or by observing their real-life choices.
Question 6: If faced with a surgical emergency in a child of 15 years for whom no consent is available for life-saving surgery and no time for seeking authority from someone, the next step should be :
- A. Conservative management till lawyer is available
- B. Consent arrangement through Hospital Social Worker
- C. Go ahead with surgery without consent (Correct Answer)
- D. Search for relatives or neighbours
Explanation: ***Go ahead with surgery without consent*** - In a **life-threatening emergency**, when a child's life is at stake and there is no time to obtain consent from parents or legal guardians, the **principle of implied consent** or necessity overrides the need for explicit consent. - The primary ethical and legal responsibility is to save the patient's life, and delaying surgery for consent could be considered **negligent** and harmful. *Conservative management till lawyer is available* - Delaying life-saving surgery in an emergency for legal consultation would be a breach of the **duty of care** and could result in the child's death. - The immediate priority in a surgical emergency is to provide the necessary medical intervention, not to seek legal advice on consent. *Consent arrangement through Hospital Social Worker* - While a hospital social worker can assist in locating family or arranging consent in non-emergent situations, the question specifies "no time for seeking authority from someone" and a "surgical emergency." - This option would still involve a delay that could be fatal in a life-saving scenario. *Search for relatives or neighbours* - This option directly contradicts the premise that there is "no time for seeking authority from someone" for life-saving surgery. - While efforts should be made to contact guardians, in a dire emergency, the **immediate medical intervention** takes precedence over searching for individuals who can provide consent.
Question 7: A person presents to the outpatient department with tremors and visual hallucinations after a 2-day history of alcohol cessation. What is the diagnosis?
- A. Korsakoff’s psychosis
- B. Delirium tremens (Correct Answer)
- C. Wernicke encephalopathy
- D. Alcoholic hallucinosis
Explanation: ***Delirium tremens*** - Delirium tremens is a severe form of **alcohol withdrawal** characterized by **tremors**, disorientation, and **visual hallucinations**, typically appearing **48 to 96 hours** (2-4 days) after the last drink. - This is a medical emergency with potential for **seizures**, **hyperthermia**, and **cardiovascular collapse** due to dysregulation of neurotransmitters (decreased **GABA** activity and increased **glutamate** activity). - Autonomic hyperactivity (tachycardia, hypertension, diaphoresis) is a key feature distinguishing it from other alcohol-related conditions. *Korsakoff's psychosis* - This is a chronic **neuropsychiatric syndrome** typically occurring after an episode of **Wernicke encephalopathy**, characterized by severe **memory impairment** (anterograde and retrograde amnesia) and **confabulation**. - It develops over weeks to months in the course of chronic alcoholism and is **not an acute withdrawal syndrome**, unlike the symptoms described in this 2-day presentation. *Wernicke encephalopathy* - This is an acute neurological condition caused by **thiamine (vitamin B1) deficiency**, commonly seen in chronic alcoholics, characterized by the classic triad of **ophthalmoplegia** (especially nystagmus), **ataxia**, and **confusion**. - While it can precede Korsakoff's psychosis and involves confusion, it does not typically present with the prominent **tremors** and **visual hallucinations** characteristic of alcohol withdrawal, and the timing (2 days post-cessation) points more toward withdrawal rather than nutritional deficiency. *Alcoholic hallucinosis* - Alcoholic hallucinosis involves primarily **auditory hallucinations** (often threatening voices) that occur without significant clouding of consciousness, typically within **12-24 hours** of alcohol cessation. - Unlike delirium tremens, it **lacks autonomic instability**, severe tremors, and global disorientation, and the hallucinations are predominantly auditory rather than visual.
Question 8: 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 9: 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 10: 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.
