Kaplan and Sadocks Synopsis of Psychiatry 12th Edition Test Bank

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.

Correct Answer: B

Rationale: The correct answer is B: Enroll the patient in an exercise program that meets regularly. Regular exercise has been shown to have numerous benefits for brain health, including improving cognitive function and reducing the risk of cognitive decline. Exercise also helps in maintaining a healthy immune system by promoting the circulation of immune cells throughout the body. This can help support the protective abilities of immune cells related to Alzheimer's disease. Minimizing contact with the public during cold and flu season (Choice A) may reduce the risk of infections but does not directly address immune cell function. Providing supplements to enhance the patient's immune system (Choice C) may not be supported by scientific evidence and can potentially have adverse effects. Identifying creative ways to keep the patient mentally challenged (Choice D) is beneficial for cognitive health but does not directly target immune cell function as effectively as regular exercise.

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 stating the goals of the group is reflective of the forming stage where members clarify the purpose and direction. Choice B is incorrect as determining leadership roles typically occurs during the storming stage. Choice C is incorrect as involving family members is not part of the group development process. Choice D is incorrect as discussing personal situations usually happens during the norming or performing stages, not in the initial forming stage.

Correct Answer: D

Rationale: The correct answer is D because discussing feelings about leaving the group and the support found within the group is crucial during the termination phase. This allows for processing emotions, reflecting on progress, and providing closure. Choice A focuses on future goals, not on the current phase. Choice B addresses time constraints, not emotional support. Choice C is about coping strategies, which may not be the priority during termination. Thus, D is the most appropriate intervention for this phase.
