Kaplan and Sadocks Synopsis of Psychiatry Questions

Correct Answer: C

Rationale: The correct answer is C: An increase in the brain chemical dopamine explains the presence of delusions and hallucinations. In paranoid schizophrenia, there is an overactivity of dopamine receptors in the brain, leading to an excess of dopamine. This excess dopamine is associated with symptoms like delusions and hallucinations. Therefore, an increase in dopamine levels is directly linked to these specific symptoms in individuals with paranoid schizophrenia. Explanation for why the other choices are incorrect: A: Breakdown of dopamine producing LSD does not directly relate to the symptoms of paranoid schizophrenia. B: Decreased amounts of dopamine do not explain the presence of delusions and hallucinations in paranoid schizophrenia; it is the increase in dopamine that is associated with these symptoms. D: An increase in dopamine is more closely related to delusions and hallucinations rather than lack of motivation and disordered affect in paranoid schizophrenia.

Correct Answer: A

Rationale: The correct answer is A: Praising him for positive behavioral changes. This measure reinforces the patient's use of effective coping techniques, providing positive feedback and motivation. This positive reinforcement encourages the patient to continue utilizing these strategies. Choices B, C, and D are incorrect: B: Avoiding setting limits that would increase his anxiety level - This does not actively support the patient's goal of recognizing and using more effective coping techniques. C: Isolating him from more seriously ill patients - Isolation does not promote the practice of coping techniques and may hinder the patient's social interaction and progress. D: Recommending that he avoid group activities for a while - Avoiding group activities contradicts the goal of attending occupational therapy groups and working towards improved coping techniques.

Correct Answer: C

Rationale: The correct answer is C: Repeating, milk, milk, milk, milk until given a drink. This behavior is a characteristic of children with autism, known as echolalia. Echolalia is the repetition of words or phrases spoken by others, often used by individuals with autism to communicate or self-soothe. This behavior is a common feature of autism spectrum disorder and is indicative of language difficulties and communication challenges. Choices A, B, and D are incorrect because they do not specifically relate to behaviors typically observed in children with autism. Referring to an imaginary friend (A) is not exclusive to autism, asking to telephone friends on weekends (B) is a social behavior that can be seen in children without autism, and insisting on a dim light in the bedroom (D) is a preference that does not directly relate to the core characteristics of autism.

Correct Answer: C

Rationale: The correct answer is C: Medications the patient has recently taken. This information is crucial because certain medications can cause symptoms of delirium or exacerbate confusion in elderly patients. By reviewing the patient's recent medications, healthcare providers can identify potential drug-induced causes of confusion and adjust the treatment accordingly. Choice A (Evidence of spasticity or flaccidity) is incorrect because these symptoms are more related to neurological conditions such as stroke or spinal cord injury, not specifically delirium. Choice B (The patient�s level of motor activity) is not as relevant in distinguishing delirium from other problems as medication history, as motor activity can be influenced by various factors. Choice D (Level of preoccupation with somatic symptoms) is also less relevant compared to medication history in differentiating delirium, as somatic symptoms may not always directly indicate the underlying cause of confusion in elderly patients.

Correct Answer: A

Rationale: Step 1: Electroconvulsive therapy (ECT) is a treatment for severe depression and other mental health disorders. Step 2: Current biological theory suggests that ECT produces changes in brain chemistry, specifically neurotransmitters, leading to improved mood. Step 3: The correct answer (A) aligns with this theory by explaining how ECT impacts brain chemistry to alleviate symptoms. Step 4: Answer B is incorrect as ECT is not used as punishment but as a therapeutic intervention. Step 5: Answer C is incorrect as ECT is not primarily used to interrupt brain impulses causing hallucinations and delusions. Step 6: Answer D is incorrect as ECT does not shock the brain into re-establishing normal electrical patterns but rather affects neurotransmitter levels.
