Principles of Consultation-Liaison Psychiatry Indian Medical PG Practice Questions and MCQs
Question 1: Psychodynamic model of disease explains the psychopathologic cause of all mental illness to be
- A. Structural and functional defect in CNS
- B. Maladaptive
- C. Cognition difficulties
- D. Unconscious conflict (Correct Answer)
Explanation: **Correct: Unconscious conflict** - The **psychodynamic model**, largely based on Freudian theory, posits that psychopathology arises from unresolved **unconscious conflicts** or repressed urges and experiences. - These conflicts typically stem from early childhood experiences and defense mechanisms used to cope with them, leading to symptomatic behavior. - This is the fundamental explanatory mechanism of the psychodynamic framework. *Incorrect: Structural and functional defect in CNS* - This explanation aligns with the **biomedical model**, which attributes mental illness to biological factors like **neurotransmitter imbalances**, genetic predispositions, or brain abnormalities. - While biological factors are crucial in understanding some mental illnesses, they are not the primary explanatory mechanism in the psychodynamic framework. *Incorrect: Maladaptive* - While psychopathology often involves **maladaptive behaviors** or thought patterns, the psychodynamic model views these as symptoms or manifestations of the underlying unconscious conflict, rather than the root cause itself. - Other models, like **behavioral psychology**, focus more directly on maladaptive learning as the primary cause. *Incorrect: Cognition difficulties* - **Cognitive difficulties** and distortions are central to the **cognitive model** of psychopathology, which suggests that mental illness results from faulty thinking patterns or dysfunctional schemas. - The psychodynamic model acknowledges intellectual functions, but it primarily sees disturbances in cognition as driven by deeper, unconscious emotional processes.
Question 2: GATHER approach of counselling is used for
- A. Breaking any bad news
- B. Communication of breast cancer prognosis
- C. Contraceptives (Correct Answer)
- D. All of the options
Explanation: ***Contraceptives*** - The **GATHER approach** (Greet, Ask, Tell, Help, Explain, Return) is a structured counseling model specifically designed for **family planning** and contraceptive guidance. - It ensures a comprehensive discussion that empowers individuals to make informed choices about their **contraceptive methods**. *Breaking any bad news* - Counseling for breaking bad news often utilizes models like **SPIKES (Setting, Perception, Invitation, Knowledge, Emotions, Strategy and Summary)**, which focus on empathy and managing patient reactions. - The GATHER approach is not specifically tailored for delivering difficult news, as its structure is more focused on information exchange and shared decision-making regarding a medical intervention. *Communication of breast cancer prognosis* - Communicating prognosis for serious illnesses like breast cancer requires a sensitive and nuanced approach, often integrating elements of **empathy, hope, and realistic expectations**. - While general communication skills are important, the GATHER model's steps are not specifically designed for the delicate nature of discussing a cancer prognosis. *All of the options* - The GATHER model is a specialized tool, and while its principles may overlap with good communication in general, it is not universally applicable to all counseling scenarios. - It is specifically optimized for guiding discussions and decisions related to **family planning and contraceptive use**.
Question 3: A patient tells psychiatrist: "My brain is missing. What is the point of me eating anything. I am already dead". The patient has which type of delusion?
- A. Nihilistic delusion (Correct Answer)
- B. Delusion of misidentification
- C. Bizarre Delusion
- D. Hypochondriacal Delusion
Explanation: ***Nihilistic delusion*** - The patient's statements ("**My brain is missing**," "**I am already dead**," "What is the point of me eating anything") are characteristic of **nihilistic delusions**, specifically Cotard's syndrome. - This type of delusion involves a belief in the non-existence of oneself, parts of one's body, or the entire world. *Delusion of misidentification* - This involves a belief that familiar people or objects have been replaced by imposters, or that someone is a different person entirely. - The patient's statements do not describe the misidentification of another person or object. *Bizarre Delusion* - While the statements could be considered bizarre, **bizarre delusions** are defined as clearly implausible, not understandable, and not derived from ordinary life experiences (e.g., aliens implanted a chip in my brain). - Nihilistic delusions, especially in the context of Cotard's syndrome, are a specific subtype of delusion that can be bizarre, but "nihilistic delusion" is a more precise characterization here. *Hypochondriacal Delusion* - This involves a false belief of having a severe disease despite medical reassurance. - While there is a physical component to the delusion ("my brain is missing"), the overarching theme of non-existence and being dead goes beyond a simple preoccupation with illness.
Question 4: The most common postoperative psychiatric condition is:
- A. Schizophrenia
- B. Delirium (Correct Answer)
- C. Chronic brain syndrome
- D. Depression
Explanation: ***Delirium*** - **Delirium** is the most common postoperative psychiatric condition, characterized by an acute onset of **waxing and waning attention**, **disorganized thinking**, and altered level of consciousness. - It is often seen in elderly patients and those with pre-existing cognitive impairment, due to the stress of surgery, anesthesia, and medication effects. *Schizophrenia* - **Schizophrenia** is a chronic psychotic disorder with onset typically in late adolescence or early adulthood, characterized by hallucinations, delusions, and disorganized thinking. - It is not typically triggered by surgery but rather a long-term psychiatric illness with a different etiology. *Chronic brain syndrome* - **Chronic brain syndrome** is an outdated term typically used to describe **dementia** or other persistent cognitive impairments. - While patients with chronic cognitive impairment are at higher risk for postoperative delirium, chronic brain syndrome itself is not an acute postoperative psychiatric condition. *Depression* - **Depression** is a common mood disorder characterized by persistent sadness, loss of interest, and other symptoms. - While depression can occur postoperatively, especially in patients with prolonged recovery or poor outcomes, it is typically not the most common acute psychiatric condition immediately following surgery.
Question 5: Delusions are typically associated with various psychiatric conditions. Which of the following conditions is least likely to present with delusions?
- A. Schizophrenia
- B. Dementia
- C. Conversion disorder (Correct Answer)
- D. Major depressive disorder
Explanation: ***Conversion disorder*** - This condition involves **neurological symptoms** (e.g., paralysis, blindness, seizures) that are **incompatible with neurological disease**, but **delusions are not a core feature**. - Symptoms are often preceded by **psychological stress or trauma** and are not intentionally produced, nor are they based on fixed, false beliefs. *Schizophrenia* - **Delusions** are a **hallmark symptom** of schizophrenia, often involving paranoid, grandiose, or bizarre beliefs. - They are a **positive symptom** reflecting a distortion of normal mental functions. *Dementia* - Patients with dementia, particularly in later stages, can frequently develop **delusions**, often paranoid (e.g., belief that caregivers are stealing their belongings) or misidentification delusions. - These delusions are usually **less systematized or bizarre** than those seen in schizophrenia and are often related to cognitive impairment. *Major depressive disorder* - In severe cases of major depressive disorder with **psychotic features**, individuals can experience **delusions** that are typically mood-congruent (e.g., delusions of guilt, worthlessness, nihilism). - These psychotic symptoms are directly related to the depressive mood.
Question 6: India is a country with different cultures and diverse languages. Which steps should a physician take to address the patient for better outcomes? 1. Insist on good communication 2. Insist on communication only via an interpreter 3. Treat them regardless of their cultural perceptions 4. The physician should consider the patient's religion and cultural perception Select the correct combination:
- A. 1,4 (Correct Answer)
- B. 1,2
- C. 2,3
- D. 3,4
Explanation: ***1,4*** - **Good communication** is paramount in healthcare, especially in a diverse country like India, to ensure **patient understanding**, **adherence** to treatment plans, and overall patient satisfaction. - Considering a patient's **religion and cultural perceptions** allows the physician to tailor treatment and communication in a sensitive and **respectful manner**, fostering trust and better **health outcomes**. *1,2* - While good communication (1) is vital, **insisting solely on an interpreter** (2) may not always be feasible or necessary, particularly if the physician and patient share a common language or if the patient prefers direct communication. This can also disrupt the flow of rapport building. - **Over-reliance on interpreters** can sometimes lead to misinterpretations or loss of non-verbal cues if the interpreter is not trained in medical interpretation. *2,3* - **Insisting only on an interpreter** (2) can be restrictive and may compromise direct patient-physician rapport, as discussed above. - **Treating patients regardless of their cultural perceptions** (3) is an ethnocentric approach that can lead to mistrust, non-adherence, and ultimately **poor health outcomes** as it disregards the patient's beliefs and values regarding health and illness. *3,4* - **Treating patients regardless of their cultural perceptions** (3) can result in a lack of understanding and non-adherence if the treatment conflicts with the patient's deeply held beliefs. - While considering religion and cultural perception (4) is crucial, this option includes an incorrect approach (3) that can undermine patient care.
Question 7: 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 8: Steps in review of patient's history during secondary survey of trauma care can be summarised as
- A. TRIAGE
- B. ABCDE
- C. AMPLE (Correct Answer)
- D. None of the options
Explanation: ***AMPLE*** - The **AMPLE history** is a mnemonic used during the **secondary survey** in trauma care to gather crucial patient information - It stands for **Allergies, Medications, Past medical history/Pregnancy, Last meal, and Events** surrounding the injury. *TRIAGE* - **Triage** is the process of prioritizing patients based on the severity of their condition and the likelihood of benefit from immediate treatment. - It is an initial assessment done to determine the urgency of care, not a detailed historical review for a single patient. *ABCDE* - The **ABCDE approach** (**Airway, Breathing, Circulation, Disability, Exposure**) is part of the **primary survey** in trauma care. - It focuses on identifying and managing immediate life-threatening conditions. *None of the options* - This option is incorrect because **AMPLE** specifically describes the historical review process during the secondary survey.
Question 9: In which context are leading questions allowed?
- A. Cross-examination (Correct Answer)
- B. Direct examination
- C. Re-examination
- D. Dying declaration
Explanation: ***Cross-examination*** - Leading questions are permissible during **cross-examination** to challenge the witness's testimony and test credibility. - The purpose is to **elicit specific details**, confirm facts, or highlight inconsistencies in prior statements. *Direct examination* - Leading questions are **generally not allowed** during direct examination because it is the phase where a party questions its own witness. - The goal is for the witness to provide testimony in their **own words**, without suggestions from the attorney. *Re-examination* - Leading questions are **not allowed** during re-examination, which occurs after cross-examination to clarify points raised. - The scope of re-examination is **limited to the matters** brought up during cross-examination, and leading questions would be inappropriate. *Dying declaration* - A dying declaration is a statement made by a person who believes they are about to die, concerning the cause of their death. - The admissibility of a dying declaration as evidence is an **exception to the hearsay rule** and does not involve questioning by attorneys in a formal court setting at the time the declaration is made.
Question 10: Choose the correctly matched pairs regarding the drugs used in schizophrenia: 1. D2 antagonism: Reduces positive symptoms 2. 5HT2A antagonism: Reduces negative symptoms 3. 5HT1A agonism: Weight loss 4. Muscarinic antagonism: Reduces extrapyramidal symptoms
- A. 1,4
- B. 1,2,4
- C. 1,2,3,4
- D. 1,2 (Correct Answer)
Explanation: ***1,2*** - **D2 antagonism** is the primary mechanism by which antipsychotics reduce **positive symptoms** of schizophrenia, such as hallucinations and delusions. - **5HT2A antagonism** is a key mechanism of atypical antipsychotics contributing to the reduction of **negative symptoms** (e.g., apathy, anhedonia, flat affect) and cognitive deficits, while also reducing the risk of extrapyramidal symptoms. *1,2,3,4* - This option is incorrect because **5HT1A agonism** is not associated with **weight loss**. While 5HT1A partial agonism (as seen with aripiprazole and brexpiprazole) may improve negative symptoms, anxiety, and cognitive function, it does not directly cause weight loss. - Additionally, **muscarinic antagonism** does not reduce extrapyramidal symptoms as a primary mechanism. Rather, anticholinergic (muscarinic antagonist) drugs like benztropine are used to **treat** EPS after it occurs. The reduction of EPS in atypical antipsychotics primarily comes from 5HT2A antagonism and lower D2 binding affinity. *1,2,4* - This option is incorrect because **muscarinic antagonism** is not a mechanism that reduces EPS. Anticholinergic agents are used therapeutically to counteract EPS caused by dopamine blockade, but anticholinergic effects themselves do not prevent or reduce EPS. - The reduction of EPS with atypical antipsychotics is mainly due to **5HT2A antagonism** balancing dopaminergic blockade, selective limbic over striatal binding, and fast D2 dissociation kinetics. *1,4* - This option is incorrect because it omits **5HT2A antagonism**, which is crucial for reducing **negative symptoms** in schizophrenia. - It also incorrectly includes muscarinic antagonism as a mechanism that reduces EPS, when in reality anticholinergics are used to treat EPS rather than prevent it.
