Personality Disorders Practice Questions

Q: A 34-year-old female with a diagnosis of borderline personality disorder presented to the casualty with a history of poison consumption following an argument. She was reluctant to disclose the consumed substance. She was initially treated with stomach wash and IV fluids. After one week, she developed jaundice, ascites, and encephalopathy. What is the likely poison responsible for acute liver failure?

Zinc phosphide. ### Explanation **Correct Option: A. Zinc phosphide** Zinc phosphide is a common rodenticide that causes multi-organ failure. The clinical presentation typically follows a **biphasic pattern**. Initially, patients present with gastrointestinal irritation (nausea, vomiting, abdominal pain). This is followed by a "latent period" or a delayed phase (usually 48 hours to several days later) characterized by **severe hepatotoxicity**, leading to jaundice, ascites, and hepatic encephalopathy (Acute Liver Failure). In the context of Borderline Personality Disorder (BPD), impulsive self-harm via rodenticide ingestion is a frequent clinical scenario. **Analysis of Incorrect Options:** * **B. Pyrethrum:** These are insecticides with low mammalian toxicity. Poisoning usually presents with hypersensitivity reactions, dermatitis, or respiratory symptoms (asthma), but not acute liver failure. * **C. Ethylene Glycol:** Found in antifreeze, this primarily causes a high anion gap metabolic acidosis and **Acute Kidney Injury (AKI)** due to calcium oxalate crystal deposition in renal tubules. It does not typically cause primary acute liver failure. * **D. Carbamate poisoning:** Similar to organophosphates, these inhibit acetylcholinesterase. Presentation involves a **cholinergic crisis** (SLUDGE: Salivation, Lacrimation, Urination, Defecation, GI distress, Emesis). Death usually occurs due to respiratory failure, not delayed hepatic failure. **High-Yield Clinical Pearls for NEET-PG:** * **BPD & Self-Harm:** Patients with BPD often use "parasuicidal" gestures (non-fatal self-harm) as a cry for help or to regulate intense affect. * **Zinc Phosphide "Garlic Odor":** A classic sign is a distinct garlic-like odor in the breath or vomitus due to the release of phosphine gas. * **Hepatotoxicity Triad:** When a question mentions delayed jaundice and encephalopathy after poisoning, think of **Zinc Phosphide, Paracetamol (Acetaminophen), or Carbon Tetrachloride.**

Q: All of the following are cluster A personality disorders except?

Avoidant personality disorder. **Explanation:** Personality disorders in the DSM-5 are categorized into three clusters (A, B, and C) based on shared descriptive characteristics. **1. Why Avoidant Personality Disorder is the Correct Answer:** Avoidant personality disorder belongs to **Cluster C**, which is characterized by **anxious or fearful** behaviors. Individuals with this disorder experience intense feelings of inadequacy and are hypersensitive to negative evaluation, leading them to avoid social interaction despite a desire for closeness. **2. Analysis of Incorrect Options (Cluster A):** Cluster A disorders are characterized by **odd or eccentric** behaviors and share a genetic link with schizophrenia spectrum disorders. * **Paranoid Personality Disorder:** Characterized by pervasive distrust and suspiciousness of others. * **Schizoid Personality Disorder:** Characterized by social detachment (disinterest in relationships) and a restricted range of emotional expression ("loners"). * **Schizotypal Personality Disorder:** Characterized by acute discomfort in close relationships, cognitive/perceptual distortions, and eccentricities (e.g., magical thinking). **3. NEET-PG Clinical Pearls:** * **Cluster A (Odd/Eccentric):** Paranoid, Schizoid, Schizotypal. (Mnemonic: **PSS**) * **Cluster B (Dramatic/Erratic):** Antisocial, Borderline, Histrionic, Narcissistic. (Mnemonic: **ABHN**) * **Cluster C (Anxious/Fearful):** Avoidant, Dependent, Obsessive-Compulsive. (Mnemonic: **ADO**) * **High-Yield Distinction:** Schizoid patients *prefer* to be alone (socially indifferent), whereas Avoidant patients *want* friends but are too afraid of rejection (socially anxious). * **Genetic Link:** Cluster A has the strongest association with a family history of Schizophrenia.

Q: Which of the following is characteristic of Borderline Personality Disorder?

Unstable and intense interpersonal relationships. **Explanation:** **Borderline Personality Disorder (BPD)** is a Cluster B personality disorder characterized by a pervasive pattern of instability in affect, self-image, and interpersonal relationships. 1. **Why Option A is Correct:** The hallmark of BPD is **interpersonal instability**. Patients often experience "splitting" (idealization and devaluation), where they view others as either "all good" or "all bad." This leads to intense, volatile relationships characterized by a desperate fear of real or imagined abandonment. 2. **Why Other Options are Incorrect:** * **Option B (Violation of rules):** This is characteristic of **Antisocial Personality Disorder**, where there is a pervasive pattern of disregard for the rights of others and social norms. * **Option C (Grandiose self-perception):** This defines **Narcissistic Personality Disorder**, marked by a lack of empathy and a need for constant admiration. * **Option D (Attention-seeking behavior):** While BPD patients may seek attention via self-harm, "pervasive attention-seeking" and inappropriate seductiveness are the primary features of **Histrionic Personality Disorder**. **High-Yield Clinical Pearls for NEET-PG:** * **Defense Mechanism:** The most characteristic primitive defense mechanism is **Splitting**. * **Key Symptoms:** Chronic feelings of emptiness, transient stress-related paranoia, and recurrent suicidal behavior or self-mutilation (e.g., wrist cutting). * **Treatment of Choice:** **Dialectical Behavior Therapy (DBT)** is the gold-standard psychotherapy. * **Pharmacotherapy:** Low-dose antipsychotics or SSRIs may be used for symptom management (mood/impulsivity), but there is no FDA-approved drug specifically for BPD.
