Kaplan and Sadocks Synopsis of Psychiatry 12th Edition Test Bank

Correct Answer: C

Rationale: The correct answer is C because intervening immediately after the loss has occurred allows for timely support and processing of emotions. This is crucial for healthy grieving and preventing complications. Choice A is too broad and not specific to the immediate need post-loss. Choice B focuses on pre-loss, which is not the most effective time for intervention. Choice D puts the responsibility on the patient, which may delay necessary support.

Correct Answer: B

Rationale: The correct answer is B: ECT induces a grand mal seizure. This indicates learning has occurred because ECT does indeed induce a controlled grand mal seizure to treat severe depression. Euphoria (A) and catatonia (C) are not accurate states induced by ECT. A petit mal seizure (D) is a mild form of seizure not associated with ECT.

Correct Answer: B

Rationale: The correct answer is B: Tourette�s disorder. The child's inability to sit still and jerking arms suggest motor tics, which are common in Tourette's disorder. Tourette's is characterized by involuntary repetitive movements or sounds. Choice A is incorrect as oppositional-defiant disorder does not involve physical tics. Choice C is a duplicate. Choice D is incorrect as it assumes defiance rather than considering a neurological explanation for the behavior.

Correct Answer: D

Rationale: The correct answer is D because haloperidol is a dopamine receptor antagonist. By blocking dopamine receptors, it reduces the activity of dopamine in the brain, which helps in reducing disturbed thought processes. Option A is incorrect as dopamine craving is not related to the mechanism of action of haloperidol. Option B is incorrect as enhancing dopamine receptors would increase dopamine activity, opposite to the intended effect of haloperidol. Option C is incorrect as increasing cellular production of dopamine would also increase dopamine activity, contradicting the purpose of using haloperidol.

Correct Answer: A

Rationale: The correct answer is A because feeling numb and detached from emotions is a common symptom of PTSD known as emotional numbing. This symptom is often seen in individuals who have experienced a traumatic event, such as the murder of a loved one. It is a defense mechanism that helps the person cope with overwhelming emotions. The other choices are incorrect: B: Being nervous and easily startled (hypervigilance) is more indicative of the hyperarousal symptom of PTSD, not emotional numbing. C: Difficulty sleeping is a common symptom of PTSD, known as insomnia, but it does not directly relate to emotional numbing. D: Reliving the traumatic event through flashbacks or intrusive memories is a symptom of PTSD, but it is not directly related to emotional numbing.
