Correct Answer: A

Rationale: Option A is the correct answer as the DSM-5 not only provides specific criteria for diagnosing mental disorders but also includes information on cultural considerations. Understanding cultural factors is crucial in making accurate diagnoses and providing appropriate care, highlighting the comprehensive nature of the DSM-5 for healthcare providers. Choices B, C, and D are incorrect because while the DSM-5 is indeed a tool for healthcare providers, it is also used in legal settings, and it focuses on diagnostic criteria and not just the prevalence of mental disorders.

Correct Answer: A

Rationale: The correct answer is A: Preoccupation with a perceived physical defect. Individuals with body dysmorphic disorder exhibit an obsessive preoccupation with a perceived flaw in their physical appearance, which is often minor or not noticeable to others. This preoccupation causes distress and leads to repetitive behaviors like mirror checking or seeking reassurance about their appearance. Choices B, C, and D are incorrect because fear of gaining weight is more characteristic of an eating disorder, excessive worry about physical symptoms may be seen in somatic symptom disorder, and persistent depressive mood aligns more with depressive disorders rather than body dysmorphic disorder.

Correct Answer: A

Rationale: Setting a time limit for hand washing is an effective intervention in managing obsessive-compulsive disorder (OCD) symptoms. By establishing boundaries around the behavior, the client can gradually work towards reducing the excessive hand washing and regaining control over the compulsion. Choice B is not as effective because it does not address the underlying compulsion. Choice C may not be helpful as it may not satisfy the client's need for cleanliness and could reinforce the behavior. Choice D, while important in therapy, may not be the most immediate intervention needed to address the excessive hand washing behavior.

Correct Answer: B

Rationale: In individuals with post-traumatic stress disorder (PTSD), hypervigilance is a common symptom. Hypervigilance refers to a state of increased alertness, awareness, and sensitivity to potential threats or danger. This heightened state of vigilance can manifest as being easily startled, having difficulty relaxing or sleeping, and constantly scanning the environment for signs of danger. It is an adaptive response to the trauma experienced and can significantly impact the individual's daily functioning. The other options are not typically associated with PTSD. Delusions of grandeur are more commonly seen in certain psychiatric disorders like bipolar disorder or schizophrenia. Obsessive-compulsive behaviors are characteristic of obsessive-compulsive disorder (OCD), not PTSD. Periods of excessive sleeping may be seen in conditions like depression, but they are not a hallmark symptom of PTSD.

Correct Answer: A

Rationale: Individuals with factitious disorder deliberately fabricate or exaggerate symptoms to assume the sick role and garner attention. They may show a lack of concern about their symptoms, a phenomenon known as la belle indiff©rence. Fear of gaining weight is not typically associated with factitious disorder. Therefore, the correct behavior to expect in a client with factitious disorder is the intentional production of false symptoms. Choices B, C, and D are incorrect as lack of concern about symptoms and fear of gaining weight are not characteristic of factitious disorder. Additionally, factitious disorder involves the intentional, not unintentional, production of false symptoms.
