Q&A: Substance Use and Personality Disorders 1. A 35-year-old homeless veteran is brought to the emergency department by the police; he is not sure why he is there. He is clearly euphoric but also agitated and somewhat paranoid; he says he “feels fantastic” but is wary of answering any questions. On physical examination, the patient exhibits a moderately elevated blood pressure and pulse rate. He is most likely intoxicated with which of the following substances? A. Alcohol B. Barbiturates C. Benzodiazepines D. Cocaine E. Opiates 1. A 35-year-old homeless veteran is brought to the emergency department by the police; he is not sure why he is there.

He is clearly euphoric but also agitated and somewhat paranoid; he says he “feels fantastic” but is wary of answering any questions. On physical examination, the patient exhibits with dilated pupils, a moderately elevated blood pressure and pulse rate. He is most likely intoxicated with which of the following substances? A. Alcohol B. Barbiturates C. Benzodiazepines D. Cocaine E. Opiates 2. Which of the following tests would be the most useful in determining the etiology of her symptoms? (A) Blood glucose (B) Catecholamine metabolites (C) Electrocardiogram (ECG) (D) Thyroid function (E) Urine toxicology 2. Which of the following tests would be the most useful in determining the etiology of her symptoms? (A) Blood glucose (B) Catecholamine metabolites (C) Electrocardiogram (ECG) (D) Thyroid function (E) Urine toxicology 2. Which of the following tests would be the most useful in determining the etiology of her symptoms? (A) Blood glucose (B) Catecholamine metabolites (C) Electrocardiogram (ECG) (D) Thyroid function (E) Urine toxicology (E) In this patient on no medications, a urine toxicology screen is most likely to determine the cause of her current state, probably due to drug intoxication. Blood glucose is important to test since hypoglycemia can present with mental status changes and diaphoresis; however, it would be unlikely in this otherwise healthy man. Catecholamine metabolites would be premature at this time. An ECG would be part of a workup to rule out any arrhythmias, but any abnormalities would not necessarily identify a specific etiology or account for his dilated pupils. Thyroid function tests are important, as thyrotoxicosis can manifest with panic-type symptoms, but again, in a healthy man with an acute onset of symptoms, the urine drug screen is more likely to yield an etiology. Cocaine Intoxication D. Cocaine intoxication (or other stimulants like amphetamine) can present with euphoria, irritability, anxiety, psychotic symptoms such as paranoia, as well as with elevated vital signs. Conversely, intoxication with alcohol, barbiturates, benzodiazepines, and opiates generally causes depression, somnolence, and depressed vitals signs. Cocaine Associated Behavioral and Physical Changes 3. A frustrated mother brings her 14-year-old son to a child psychiatrist after he is expelled from three high schools in 1 year. She reports the boy has tried twice to set his school on fire, has slashed school bus tires, and has broken into the principal’s office to steal athletic trophies. In addition, he has been suspended numerous times for getting into fights with other students. She shudders and tearfully relates that she recently caught him singing one of the family cats with a cigarette butt. Which of the following personality disorders is this boy most at risk of developing in the future? A. Antisocial B. Borderline C. Histrionic D. Narcissistic E. Schizotypal 3.

Which of the following personality disorders is this boy most at risk of developing in the future? A. Antisocial B. Borderline C. Histrionic D. Narcissistic E. Schizotypal A. Antisocial (A) The case represents a child with conduct disorder. Individuals with conduct disorder are at increased risk of later development of antisocial personality disorder; in fact, DSM-5 criteria for antisocial personality disorder require evidence of a conduct disorder before the age of 15 years. 4. An 18-year-old, pregnant, human immunodeficiency virus (HIV)– positive woman presents for the treatment of opiate use disorder. She reports using heroin for the last 8 months with substantial (but unsuccessful) efforts to quit for the last 4 months. She is now homeless and has recently been arrested for shoplifting. Which of the following pharmacological therapies would be the most appropriate at this time? (A) Buprenorphine (B) Clonidine (C) Haloperidol (D) Methadone (E) Naloxone 4.

She reports using heroin for the last 8 months with substantial (but unsuccessful) efforts to quit for the last 4 months. She is now homeless and has recently been arrested for shoplifting. Which of the following pharmacological therapies would be the most appropriate at this time? (A) Buprenorphine (B) Clonidine (C) Haloperidol (D) Methadone (E) Naloxone (D) Methadone Methadone maintenance is the most appropriate pharmacological therapy for the treatment of opiate (heroin) use disorder, even in pregnancy. Methadone maintenance, especially when combined with psychosocial services and obstetric monitoring, significantly improves neonatal outcomes and obstetric outcomes for women addicted to heroin. The lowest effective dose should be used during pregnancy. There are no known teratogenic effects from methadone. Women may require higher doses of methadone in the third trimester due to increased metabolism of the drug at that time. (D) Methadone Buprenorphine is a partial opiate agonist that has a role in maintenance treatment, but its safety during pregnancy and breastfeeding has not been definitively established, and its use in pregnancy may lead to withdrawal symptoms in opioid-dependent fetuses. Clonidine can be used to treat hypertension and other symptoms during acute opiate withdrawal. While haloperidol (a firstgeneration antipsychotic) may be used safely in pregnancy, it has no use for the treatment of severe opiate use disorder, unless agitation from acute withdrawal is problematic. Naloxone is an opiate antagonist, used for opiate overdose, not appropriate in this case. 5. A 37-year-old woman, who works the night shift at a local grocery store taking inventory, reports that her childhood and college years were uneventful but happy. She spends most of her time alone when she is not at work. She does not venture out of her house and her social contacts are limited to work-related interactions with coworkers. She is an avid plant lover, and she spends most of her free time taking care of her indoor nursery. She reports that she is quite content with her life. Which of the following is the most likely diagnosis for this patient? (A) Agoraphobia (B) Autism spectrum disorder (C) Avoidant personality disorder (D) Schizoid personality disorder (E) Schizotypal personality disorder 5.

Which of the following is the most likely diagnosis for this patient? (A) Agoraphobia (B) Autism spectrum disorder (C) Avoidant personality disorder (D) Schizoid personality disorder (E) Schizotypal personality disorder (D) Schizoid Personality Disorder Persons with schizoid personality disorder are detached, reclusive, demonstrate a restricted range of affect, and do not mind the lack of social interaction. Agoraphobia is tied to the fear of having panic-type symptoms in public. Such symptoms are not mentioned in this case. Autism spectrum disorder is a developmental disorder characterized by deficits in social communication and with repetitive, restricted behaviors and interests. Persons with avoidant personality disorder are shy and fearful of social rejection. However, their lack of socialization is distressing to them. Schizotypal individuals can have schizoid features but they also have bizarre thinking and an odd or eccentric manner. 5. A 48-year-old man has been drinking up to 6 beers per night during the week and up to 12 beers a night on the weekend. A year ago, he had his driver ’s license suspended for drunk driving. His marriage is failing because of these difficulties. Last month, he was diagnosed with a gastric ulcer as a result of alcohol consumption. He admits to an alcohol problem and has tried to stop on numerous occasions. He finds that he experiences insomnia if he does not drink for more than 2 days. Which of the following features of this case suggests a severe versus moderate alcohol use disorder? (A) High quantity of alcohol consumed on a regular basis (B) History of legal problems (C) Inability to stop drinking despite knowing the harmful effects (D) Marital conflict due to drinking (E) Number of difficulties he is experiencing 5.

Number of difficulties he is experiencing (E). Number of difficulties he is experiencing The DSM-5 distinguishes the severity of alcohol (and other substance) use disorders on the basis of how many criteria are met. Criteria A include evidence of a problematic pattern of alcohol use that results in impairment and/ or distress. The DSM-5 does not distinguish abuse from dependence, and requires the number of problematic symptoms to determine severity Mild alcohol use disorder: 2-3 symptoms Moderate alcohol use disorder: 4-5 symptoms Severe alcohol use disorder: 6 or more (out of 11 listed) A 31-year-old woman was admitted to a psychiatric unit after attempting suicide by overdose. She had recently broken up with her boyfriend of 4 months. She also describes episodes of mood lability, marked by feelings of depression and anger directed toward the psychiatric resident who completed the rotation 5 days after her admission. When the resident left, she reported that she was having urges to cut her wrists. She has had numerous admissions for suicidal gestures and a lifelong history of tumultuous romantic relationships. As the patient nears her discharge date, she reports that “all the staff hates me except for Dr. Johnson.” Dr. Johnson, a medical student, had a recent difference of opinion with the nursing staff regarding the patient’s discharge. 6. Which of the following diagnoses is the most likely for this patient? (A) Borderline personality disorder (B) Cyclothymic disorder (C) Histrionic personality disorder (D) Major depressive disorder (MDD) (E) Schizoaffective disorder 6. Which of the following diagnoses is the most likely for this patient? (A) Borderline personality disorder (B) Cyclothymic disorder (C) Histrionic personality disorder (D) Major depressive disorder (MDD) (E) Schizoaffective disorder 6. Which of the following diagnoses is the most likely for this patient? (A) Borderline personality disorder (B) Cyclothymic disorder (C) Histrionic personality disorder (D) Major depressive disorder (MDD) (E) Schizoaffective disorder (A) Borderline personality disorder (A) This patient displays symptoms of fear of loss and abandonment, intense interpersonal relationships, recurrent suicidal behavior or threats, affective instability, and difficulty controlling intense anger, consistent with borderline personality disorder. Patients with cyclothymic disorder often present with similar symptoms of mood changes due to hypomanic episodes and minor depressive episodes, but they are not usually as frequent, short-lived, or intense, and they are not associated with the other symptoms of borderline personality disorder above. (A) Borderline personality disorder Patients with histrionic personality disorder, like those with borderline personality disorder, may display excessive emotionality and attention seeking, but their core symptoms center around superficial seductiveness and theatricality. While patients with borderline personality disorder may have depressive symptoms that develop into MDD, this patient’s depressive symptoms are fleeting and in response to stressors such as perceived abandonment. Although this patient appears paranoid that “all the staff hates me,” there is no other evidence for a primary psychotic illness such as schizoaffective disorder. Patients with borderline personality disorder may experience temporary psychotic symptoms, such as paranoia, or severe dissociation under times of perceived stress or substance use. 7. Which of the following would be the most appropriate outpatient treatment for this patient? (A) Antidepressants (B) Benzodiazepines (C) Group psychotherapy (D) Individual psychotherapy (E) Mood stabilizers 7. Which of the following would be the most appropriate outpatient treatment for this patient? (A) Antidepressants (B) Benzodiazepines (C) Group psychotherapy (D) Individual psychotherapy (E) Mood stabilizers 7. Which of the following would be the most appropriate outpatient treatment for this patient? (A) Antidepressants (B) Benzodiazepines (C) Group psychotherapy (D) Individual psychotherapy (E) Mood stabilizers (D) Individual Psychotherapy (D) Psychotherapy and steady social support represent the best longterm method for the management of borderline personality disorder. Antidepressants, antipsychotics, and mood stabilizers do have some efficacy in treating target symptoms in some patients with borderline personality disorder, but the long-term mainstay treatment is psychotherapy. Medication can be a useful adjunct in managing symptoms sufficiently so that the patient can later engage more effectively in psychotherapy. Benzodiazepines may treat anxiety in these patients, but they have particular abuse liability in these impulsive patients. 8. In this patient, which type of psychotherapy would be the most efficacious? (A) Cognitive-behavioral therapy (CBT) (B) Dialectical behavioral therapy (DBT) (C) Group therapy (D) Psychoanalysis (E) Psychodynamic therapy 8. In this patient, which type of psychotherapy would be the most efficacious? (A) Cognitive-behavioral therapy (CBT) (B) Dialectical behavioral therapy (DBT) (C) Group therapy (D) Psychoanalysis (E) Psychodynamic therapy (B) Dialectical behavioral therapy (DBT) DBT has shown to be particularly effective with borderline individuals, especially when used in conjunction with groups. DBT is an offshoot from CBT and focuses on mindfulness and distress tolerance. A 36-year-old man is brought to the emergency department in respiratory arrest. On examination, he is bradycardic and unresponsive, with constricted pupils bilaterally. There are no other obvious injuries on the patient, but no one is immediately available to provide collateral history. There is suspicion that the patient’s condition may be the result of an overdose. 9. Which of the following drugs is most likely to cause this presentation? (A) Alcohol (B) Cocaine (C) Heroin (D) Inhalants (E) Phencyclidine (PCP) 9. Which of the following drugs is most likely to cause this presentation? (A) Alcohol (B) Cocaine (C) Heroin (D) Inhalants (E) Phencyclidine (PCP) (C). Heroin (C) Heroin overdose is most likely to have caused the clinical situation described, including the decreased level of consciousness, respiratory depression, and pinpoint (constricted) pupils. Alcohol intoxication and PCP may cause coma but both are associated with nystagmus rather than pupillary size changes. Cocaine use causes pupillary dilatation, not constriction, and is usually associated with agitation in large amounts. Inhalants may rarely cause coma but are not classically associated with pupillary constriction. 10. Which of the following would be most important to administer immediately? (A) Acetylcysteine (B) Deferoxamine (C) Methadone (D) Methylene blue (E) Naloxone 10. Which of the following would be most important to administer immediately? (A) Acetylcysteine (B) Deferoxamine (C) Methadone (D) Methylene blue (E) Naloxone (E) Naloxone Naloxone is used to reverse the acute effects of opiate overdose by blocking CNS opioid receptors. Acetylcysteine is administered in acetaminophen overdose and deferoxamine is used in iron overdose. Methadone is used for the long-term maintenance of opiate addiction and would only worsen the symptoms of heroin overdose. Methylene blue is used to treat methemoglobinemia. A 46-year-old man with a history of hypertension and hyperlipidemia presents to his primary care doctor with complaints that “I’m drinking too much.” He gives a long history of binges over 4 to 5 days at a time, where he will drink 1 to 2 pints of gin per day. He has had several DUIs and is at risk of losing his job. In addition, his drinking has put a strain on his marriage. Unfortunately, he has been unable to maintain sobriety for any significant period of time. He is “stressed out” because of the consequences of his drinking, and he admits to chronic, intermittent insomnia. He has a good appetite, however, and his energy is adequate unless he is significantly hungover. He feels helpless but denies suicidal ideation. 11. Which of the following medications would be most appropriate to prescribe for this patient? (A) Acamprosate (B) Bupropion (C) Citalopram (D) Lithium (E) Olanzapine 11. Which of the following medications would be most appropriate to prescribe for this patient? (A) Acamprosate (B) Bupropion (C) Citalopram (D) Lithium (E) Olanzapine (A) Acamprosate This patient is suffering from alcohol use disorder. While rehabilitation is the mainstay of treatment for addictions, several medications have been beneficial in reducing alcohol use. Acamprosate, a glutamate receptor modulator, has shown efficiency in reducing craving and alcohol use. 12. Two weeks later this same patient is seen in the emergency room after being picked up by the police for disturbing the peace and wandering. On examination he appears confused, has nystagmus, and an unsteady gait. Which of the following should be administered immediately? (A) Glucose (B) Haloperidol (C) Lorazepam (D) Naltrexone (E) Thiamine 12. Two weeks later this same patient is seen in the emergency room after being picked up by the police for disturbing the peace and wandering. On examination he appears confused, has nystagmus, and an unsteady gait. Which of the following should be administered immediately? (A) Glucose (B) Haloperidol (C) Lorazepam (D) Naltrexone (E) Thiamine (E) Thiamine (E) This patient appears to be experiencing Wernicke encephalopathy, a result of chronic, heavy, alcohol use, caused by acute thiamine deficiency. It presents classically with the triad of confusion, oculomotor abnormalities (e.g., nystagmus), and ataxia. The treatment is IV thiamine. While glucose is often given in an emergency setting, as well, it is imperative to give thiamine first, as giving glucose before thiamine may worsen the encephalopathy. Haloperidol, a typical antipsychotic, is not indicated as the patient is neither psychotic nor agitated, and will not help the underlying condition. Neither lorazepam, a benzodiazepine used in acute alcohol withdrawal, nor naltrexone, an opiate antagonist used to reduce alcohol craving, will appropriately treat Wernicke encephalopathy. 13. A 36-year-old man presents to the emergency department after being found without clothing in the street. He has multiple excoriations all over his body, is paranoid and agitated, and states that bugs are crawling all over him. His vitals are as follows: T-99.1, BP-160/ 93, P105, R-20. Which of the following substances would be most likely found in his laboratory results? (A) Alcohol (B) Cannabis (C) Cocaine (D) Opiates (E) PCP 13.

Which of the following substances would be most likely found in his laboratory results? (A) Alcohol (B) Cannabis (C) Cocaine (D) Opiates (E) PCP (C). Cocaine This patient presents with disorganized behavior, agitation, paranoia, and formication (a particular type of tactile hallucination in which one has the sensation of bugs crawling on or under the skin), as well as elevated vital signs and dilated pupils. These are all consistent with acute cocaine intoxication. Intoxication with alcohol presents with decreased level of consciousness, decreased vital signs, slurred speech, and poor coordination. Cannabis intoxication can present with paranoia and tachycardia, although not usually agitation or formication. (C). Cocaine Opiate use classically presents with a decreased level of consciousness, diminished vitals, pinpoint pupils, dry skin, and constipation. Patients who use PCP may be quite agitated and paranoid, as well as have signs of sympathetic stimulation, but they often present with ataxia, fever, and nystagmus (vertical, horizontal, or rotary).

(A) Acamprosate (B) Disulfiram (C) Flumazenil (D) Naloxone (E) Naltrexone 14. Which of the following medications would be the most useful as a behavioral modifier to decrease his alcohol use? (A) Acamprosate (B) Disulfiram (C) Flumazenil (D) Naloxone (E) Naltrexone (B) Disulfiram The metabolism of ethyl alcohol involves a two-step enzymatic process. The first enzyme, alcohol dehydrogenase, metabolizes ethanol to acetaldehyde, which is quickly metabolized by aldehyde dehydrogenase. Disulfiram inhibits aldehyde dehydrogenase, resulting in accumulation of acetaldehyde. Acetaldehyde causes facial flushing, tachycardia, hypotension, nausea and vomiting, and physical discomfort. Therefore, a patient on disulfiram has an incentive to remain abstinent. Disulfiram works only if patients continue to take it. Acamprosate (a GABAergic agonist) and naltrexone (an opioid antagonist) are both used to reduce cravings for alcohol. 15. Further history reveals that he does not have a mood disorder. He tells you that often he simply cannot control his craving to have another drink. Which of the following agents would be the most likely to decrease his cravings for alcohol? (A) Bupropion (B) Disulfiram ( C) Flumazenil (D) Naloxone (E) Naltrexone 15. Further history reveals that he does not have a mood disorder. He tells you that often he simply cannot control his craving to have another drink. Which of the following agents would be the most likely to decrease his cravings for alcohol? (A) Bupropion (B) Disulfiram ( C) Flumazenil (D) Naloxone (E) Naltrexone (E) Naltrexone Multiple neurotransmitter systems have been investigated in attempts to control alcohol cravings. One system that likely plays a role in the reward pathway is the opioid system. Naltrexone is an opioid antagonist that has been shown to decrease the number of days a person with alcohol use disorder drinks and to increase the time before relapse of heavy drinking. 16. You are the consult-liaison psychiatrist on call for the trauma surgery team. You are asked to evaluate a 39-year-old man who was hit by a car and severely injured. He is unable to give a history, but an acquaintance who accompanied the patient to the hospital reports that he is a daily, heavy drug user. On examination, the patient is noted to have track marks on his arms. Which of the following classes of drugs do you tell the surgeon is the most dangerous if abruptly withdrawn? (A) Cannabinoids (B) Hallucinogens (C) Opiates (D) Sedative-hypnotics (E) Stimulants 16. You are the consult-liaison psychiatrist on call for the trauma surgery team.

Autonomic hyperactivity, orthostatic hypotension, muscle weakness, tremor, insomnia, nausea, vomiting, auditory/visual/tactile hallucinations, agitation or anxiety may occur. By far the most serious sequelae are grand mal seizures of delirium. Usually grand mal seizures develop on the second or third day of withdrawal and many have more than one seizure. Delirium may develop between the third and eight day. Minor symptoms may persist for up to 4 weeks. 17. A patient with cocaine use disorder is subsequently admitted to a detoxification unit in the hospital. After his euphoria and paranoia resolve, he is able to give a more complete history. He describes a 5-year history of almost daily crack cocaine use, with no periods of sobriety lasting for greater than several weeks. During these periods, he felt “depressed,” with an increased appetite, disrupted sleep, difficulty concentrating, and fatigue. He denies alcohol or other drug use, and his psychiatric review of systems is otherwise negative. Which of the following would be the most appropriate initial treatment for this patient? A. Antidepressant B. Dopamine antagonist C. Dopamine agonist D. Mood stabilizer E. Narcotics Anonymous 17.

Narcotics Anonymous The most beneficial approach to cocaine addiction without additional psychopathology is to stress abstinence and relapse-prevention. Narcotics Anonymous meetings are easily accessible, approachable, and provide ongoing group and individual support. No medications have been proven to prevent cocaine cravings or relapse. While the patient admits to depressive symptoms when abstinent from cocaine, these symptoms are quite common (and self-limiting) during withdrawal. Also, the time period is not typical of a major depressive disorder. After 4 to 6 weeks of sobriety, the patient should be reevaluated for a depressive disorder with consideration to begin an antidepressant. 18. A 55-year-old woman lives on her own. She wears odd clothes and pokes around in her neighbors’ garbage cans. She claims to have psychic powers but does not report hearing voices. What is the most likely diagnosis for her condition? A. Schizoid personality disorder B. Schizotypal personality disorder C. Asperger syndrome D. Avoidant personality disorder 18. A 55-year-old woman lives on her own.

Schizoid personality disorder B. Schizotypal personality disorder C. Asperger syndrome D. Avoidant personality disorder B. Schizotypal personality disorder Schizotypal personality disorder is characterized by discomfort in close relationships, cognitive and perceptual distortions, and eccentric behavior. This pattern begins in early adulthood and is present in a variety of contexts. Persons with schizotypal personality disorder usually have ideas of reference. They may also be superstitious or preoccupied with paranormal phenomena outside the norms of the subculture. 19. Which of the following is true about personality disorders? A. They rarely cause subjective distress. B. They mellow with age. C. They respond well to treatment. D. They cause little or no impairment in functioning. 19. Which of the following is true about personality disorders? A. They rarely cause subjective distress. B. They mellow with age. C. They respond well to treatment. D. They cause little or no impairment in functioning. B. They mellow with age Personality disorders are characterized by deeply ingrained, inflexible patterns of behavior. They cause conflict in relationships and impaired adaptive functioning. They usually cause subjective distress. The pervasive personality traits are evident by adolescence and persist throughout adult life, though the features tend to mellow or ameliorate with age. 20. Which of the following is characteristic of persons with paranoid personality disorder? A. Obsession B. Psychotic behavior C. Litigiousness D. Anxiety 20. Which of the following is characteristic of persons with paranoid personality disorder? A. Obsession B. Psychotic behavior C. Litigiousness D. Anxiety C. Litigiousness C. People with paranoid personality disorder show marked suspiciousness of others and are extremely sensitive to any potential threat or injustice. They look for any hidden motives or meanings and are selfrighteous and quite litigious. 21. Which of the following statements regarding alcohol's effect on sleep is false? A. Heavy drinkers often awaken at night and have difficulty going back to sleep. B. Alcoholics tend to have more dreams later in the night. C. Alcohol increases rapid eye movement (REM) sleep. D. Alcohol can significantly impair normal sleep patterns. E. Alcohol use tends to inhibit stage 4 sleep. 21. Which of the following statements regarding alcohol's effect on sleep is false? A.

Alcohol can significantly impair normal sleep patterns. E. Alcohol use tends to inhibit stage 4 sleep. C. Alcohol increases REM sleep Alcohol intoxication can help a person fall asleep more quickly, but if the intake in an evening is more than one or two drinks, the sleep pattern can be significantly impaired. Most heavy drinkers awaken after several hours and can have problems falling back asleep. Alcohol also tends to depress rapid eye movements (REMs) and inhibit stage 4 sleep and thus is likely to be associated with frequent alternations between sleep stages (sleep fragmentation) and with more dreams late in the night as the blood alcohol level decreases. Exaggerated forms of similar problems are seen in alcoholics in whom sleep stages might not return to normal for 3 or more months after abstinence. 22. In distinguishing schizophrenia from amphetamine-induced toxic psychosis, the presence of which of the following is most helpful? A. tactile or visual hallucinations B. paranoid delusions C. intact orientation D. clear consciousness E. auditory hallucinations 22. In distinguishing schizophrenia from amphetamine-induced toxic psychosis, the presence of which of the following is most helpful? A. tactile or visual hallucinations B. paranoid delusions C. intact orientation D. clear consciousness E. auditory hallucinations 22. In distinguishing schizophrenia from amphetamine-induced toxic psychosis, the presence of which of the following is most helpful? A. tactile or visual hallucinations B. paranoid delusions C. intact orientation D. clear consciousness E. auditory hallucinations A. Tactile or visual hallucinations Amphetamine-induced toxic psychosis can be exceedingly difficult to differentiate from schizophrenia and other psychotic disorders characterized by hallucinations or delusions. Paranoid delusions occur in about 80 percent of patients and hallucinations in 60 to 70 percent. Consciousness is clear, and disorientation is uncommon. The presence of vivid visual or tactile hallucinations should raise suspicion of a drug-induced disorder. In areas where and populations in whom amphetamine use is common, it may be necessary to provide only a provisional diagnosis until the patient can be observed and drug test results are obtained. 23. Minor signs and symptoms of the benzodiazepine discontinuation syndrome commonly include A. hyperpyrexia B. grand mal seizures C. psychosis D. nightmares E. death 23.

Minor signs and symptoms of the benzodiazepine discontinuation syndrome commonly include A. hyperpyrexia B. grand mal seizures C. psychosis D. nightmares E. death D.nightmares Minor symptoms include anxiety, insomnia, and nightmares. Major symptoms (which are extremely rare) include grand mal seizures, psychosis, hyperpyrexia, and death. 24. Inhalant use most often correlates with which of the following comorbid conditions? A. Borderline personality disorder B. Conduct disorder C. Major depression D. Manic episode E. Schizophrenia 24. Inhalant use most often correlates with which of the following comorbid conditions? A. Borderline personality disorder B. Conduct disorder C. Major depression D. Manic episode E. Schizophrenia B. Conduct disorder People with adolescent conduct disorder or adult antisocial personality disorder are prone to taking extreme risks, and many inhalant users have these disorders. Several studies suggest an association of inhalant use and conduct problems. 25. Cocaine A. competitively blocks dopamine reuptake by the dopamine transporter. B. does not lead to physiological dependence. C. does not induce psychotic disorders. D. has been used by 40 percent of the United States population since 1991 E. is no longer used as a local anesthetic 25. Cocaine A. competitively blocks dopamine reuptake by the dopamine transporter. B. does not lead to physiological dependence. C. does not induce psychotic disorders. D. has been used by 40 percent of the United States population since 1991 E. is no longer used as a local anesthetic A. competitively blocks dopamine reuptake by the dopamine transporter. Cocaine competitively blocks dopamine reuptake by the dopamine transporter. This primary pharmacodynamic effect is believed to be related to cocaine's behavioral effects, including elation, euphoria, heightened self-esteem, and perceived improvement on mental and physical tasks. Cocaine does lead to physiological dependence, although cocaine withdrawal is mild compared with the effects of withdrawal from opiates and opioids. A psychological dependence on cocaine can develop after a single use because of its potency as a positive reinforcer of behavior. Cocaine-induced psychotic disorders are most common in intravenous users and crack users, not in those who snort cocaine. 26. A pervasive pattern of grandiosity, lack of empathy, and need for admiration suggests the diagnosis of which of the following personality disorders? A. Borderline B. Narcissistic C. Paranoid D. Passive-aggressive E. Schizotypal 26. A pervasive pattern of grandiosity, lack of empathy, and need for admiration suggests the diagnosis of which of the following personality disorders? A. Borderline B. Narcissistic C. Paranoid D. Passive-aggressive E. Schizotypal B. Narcissistic A pervasive pattern of grandiosity (in fantasy or behavior), lack of empathy, and need for admiration suggests the diagnosis of narcissistic personality disorder. The fantasies of narcissistic patients are of unlimited success, power, brilliance, beauty, and ideal love; their demands are for constant attention and admiration. Patients with narcissistic personality disorder are indifferent to criticism or respond to it with feelings of rage or humiliation. Other common characteristics are interpersonal exploitiveness and a sense of entitlement, surprise, and anger that people do not do what the patient wants. 27. The defense mechanism most often associated with paranoid personality disorder is A. splitting B. projection C. isolation D. hypochondriasis E. dissociation 27. The defense mechanism most often associated with paranoid personality disorder is A. splitting B. projection C. isolation D. hypochondriasis E. dissociation B. Projection The defense mechanism most often associated with paranoid personality disorder is projection. The patients externalize their own emotions and attribute to others impulses and thoughts that they are unable to accept in themselves. Excessive fault finding, sensitivity to criticism, prejudice, and hypervigilance to injustice can all be understood as examples of projecting unacceptable impulses and thoughts onto others. 28. Mr. S was a 45-year-old postal service employee who was evaluated at a clinic specializing in the treatment of depression. He claimed to have felt constantly depressed since the first grade without a period of normal mood for more than a few days at a time. His depression was accompanied by lethargy; little or no interest or pleasure in anything; trouble in concentrating; and feelings of inadequacy, pessimism, and resentfulness. His only periods of normal mood occurred when he was home alone, listening to music or watching TV. On further questioning, Mr. S revealed that he could never remember feeling comfortable socially. Even before kindergarten, if he was asked to speak in front of a group of family friends, his mind would go blank. He felt overwhelming anxiety at children's social functions, such as birthday parties, which he either avoided or attended in total silence. He could answer questions in class only if he wrote down the answers in advance; even then, he frequently mumbled and could not get the answer out. He met new children with his eyes lowered, fearing their scrutiny, expecting to feel humiliated and embarrassed. He was convinced that everyone around him thought he was \"dumb or a jerk.\" The best diagnosis in the patient above is: A. adjustment disorder with anxiety B. avoidant personality disorder C. schizoid personality disorder D. schizotypal personality disorder E. social phobia He could answer questions in class only if he wrote down the answers in advance; even then, he frequently mumbled and could not get the answer out. He met new children with his eyes lowered, fearing their scrutiny, expecting to feel humiliated and embarrassed. He was convinced that everyone around him thought he was \"dumb or a jerk.\" The best diagnosis in the patient above is: A. adjustment disorder with anxiety B. avoidant personality disorder C. schizoid personality disorder D. schizotypal personality disorder E. social phobia B. Avoidant personality disorder The best diagnosis is avoidant personality disorder. Although feeling constantly depressed caused Mr. S to seek treatment, the pervasive pattern of social avoidance, fear of criticism, and lack of close peer relationships was of equal importance. Persons with avoidant personality show an extreme sensitivity to rejection, which may lead to social withdrawal. They are not asocial but are shy and show a great desire for companionship; they need unusually strong guarantees of uncritical acceptance. In the case presented, the patient exhibited a long-standing pattern of difficulty in relating to others. Persons with schizoid personality disorder do not evince the same strong desire for affection and acceptance; they want to be alone. 29. You are asked to see a 42-year-old male patient on a surgical ward who had a major operation 2 days ago and is now exhibiting bizarre behavior. He expresses fears that aliens are coming to take him away and appears to be responding to hallucinations. On examination he is tremulous and sweating but appears oriented and denies any hallucinations. His laboratory workup is subnormal with increased MCV and GGT. What is the most likely cause of his symptoms? A. Alcohol withdrawal B. Schizophrenia C. Severe depression D. Delirium tremens E. Alcoholic hallucinosis 29.

What is the most likely cause of his symptoms? A. Alcohol withdrawal B. Schizophrenia C. Severe depression D. Delirium tremens E. Alcoholic hallucinosis D. Delirium tremens The symptoms described are strongly suggestive of delirium tremens. Such symptoms can arise in patients being admitted to the hospital for an operation and hence abstaining from alcohol. The clinical features are clouding of consciousness, difficulty sustaining attention, disorientation, autonomic hyperactivity with tachycardia, excess sweating, and lability of blood pressure. Patients also have fleeting delusions and hallucinations. The symptoms should resolve with adequate treatment. 30. A 20-year-old college student is brought into the emergency room after a party. He has tenting of the skin on the backs of his hands, is nauseated, and vomits, acts seductively toward the nursing staff, and thinks the security guards are out to kill him. He tells you: "The one with the red hair is out to slay me." The emergency medical technician tells you the patient apparently collapsed while dancing at a party. What substance has he most likely taken? A. Cannabis B. Ketamine C. Diacetylmorphine D. Methylenedioxyamphetamine (MDMA) E. Inhalants 30.

What substance has he most likely taken? A. Cannabis B. Ketamine C. Diacetylmorphine D. Methylenedioxyamphetamine (MDMA) E. Inhalants D. MDMA Methylenedioxyamphetamine (MDMA) is also known as ecstasy. It is in the amphetamine family and is a common drug of abuse at clubs and raves. Symptoms of intoxication with amphetamines include euphoria, changes in sociability, hypervigilance, changes in interpersonal sensitivity, anxiety, anger, and impaired judgment. Amphetamines can induce a psychosis that includes paranoia, hyperactivity, and hypersexuality. Physical effects include fever, headache, cyanosis, vomiting (leading to dehydration), shortness of breath, ataxia, and tremor. More serious effects can include myocardial infarction, severe hypertension, and ischemic colitis. Cannabis intoxication presents as impaired coordination, euphoria or anxiety, sense of slowed time, social withdrawal, and impaired judgment. Physical signs include conjunctival injection, increased appetite, tachycardia, and dry mouth. Ketamine is a relative of PCP. Intoxication presents as belligerence, impulsivity, psychomotor agitation, and impaired judgment. Physical signs include nystagmus, hypertension, ataxia, dysarthria, or muscle rigidity. Psychosis may be present and can persist for up to 2 weeks after intoxication. D. MDMA Diacetylmorphine is heroin. Intoxication results in euphoria followed by apathy, psychomotor agitation or retardation, impaired judgment, pupillary dilation, sedation, slurred speech, and impaired attention or memory. Volatile inhalant intoxication presents as belligerence, assaultiveness, apathy, impaired judgment, dizziness, nystagmus, impaired coordination, unsteady gait, lethargy, tremor, psychomotor retardation, muscle weakness, euphoria, or coma. Low doses of these substances can cause feelings of euphoria. High doses can cause paranoia, fearfulness, and hallucinations. 31. On your drive in to work you wonder if you will encounter any violent patients during your day. If you encounter the following types of patients today, which group of patients is the most likely to attack you? A. Bipolar patients B. Schizophrenic patients C. Borderline patients D. Substance abusers E. Major depressive disorder patients 31. On your drive in to work you wonder if you will encounter any violent patients during your day. If you encounter the following types of patients today, which group of patients is the most likely to attack you? A. Bipolar patients B. Schizophrenic patients C. Borderline patients D. Substance abusers E. Major depressive disorder patients D. Substance abusers Substance abusers have the highest risk of becoming violent. Large doses of alcohol promote aggression, as do large doses of barbiturates. Paradoxical aggression can be observed with anxiolytics. Opioid dependence is associated with increased aggression. Stimulants, cocaine, hallucinogens, and sometimes cannabis can also lead to aggression. Aggressive behavior is more likely with those who have become acutely psychologically decompensated. More than half of people who commit homicide and engage in assaultive behavior are under the influence of significant amounts of alcohol at the time the crime is committed. Although many major psychiatric disorders can lead to aggression, you are more likely to face substance-induced aggression simply because of the sheer number of cases of aggression and violence that are substanceinduced. Any questions?
