Correct Answer: A

Rationale: When stress is prolonged, the body reaches the stage of exhaustion in the general adaptation syndrome, where compensatory mechanisms fail, and diseases of adaptation may occur. One physiological effect includes a decreased immune response, leading to decreased resistance to disease. Therefore, the correct answer is A. Increased libido (choice B) is not a typical physiological effect related to prolonged stress. Decreased blood pressure (choice C) is not commonly associated with sustained stress. Increased inflammatory response (choice D) may occur in the short term due to stress, but over a prolonged period, the immune system's function weakens, leading to decreased resistance to disease.

Correct Answer: A

Rationale: The correct answer is A: Somatic symptom disorder. Somatic symptom disorder is characterized by preoccupation with physical symptoms for which there is no demonstrable organic pathology. One of the diagnostic criteria is a high level of anxiety about health concerns or illness. In the DSM-5, somatic symptom disorders are classified under the category of somatic symptom and related disorders, which encompass conditions where psychological factors play a significant role in the development, exacerbation, or maintenance of physical symptoms. Choices B, C, and D are incorrect. Grief responses, psychosis, and bipolar disorder are not specifically categorized as psychoneurotic responses to severe anxiety in the DSM-5.

Correct Answer: D

Rationale: The correct answer is D. Regression involves reverting to an earlier stage of development for comfort. In this case, an adult throwing a temper tantrum is regressing to a childlike behavior when faced with not getting their way, which is a form of seeking comfort associated with earlier development. Choices A, B, and C do not exemplify regression. Blaming the teacher, becoming hysterical after a traumatic event, or seeking a partner similar to a beloved father are not instances of reverting to earlier developmental stages to cope with stress or conflict.

Correct Answer: C

Rationale: Palpitations are a common physical symptom seen in clients experiencing moderate anxiety. Fidgeting, laughing inappropriately, and nail biting can also indicate heightened stress levels. It's important for healthcare providers to recognize these signs and provide appropriate support. While anxiety can manifest in various ways, other indicators of moderate anxiety may include restlessness, difficulty concentrating, muscle tension, and sleep disturbance. It's crucial for healthcare providers to assess these symptoms to provide effective care and interventions. Laughing inappropriately and nail biting are more commonly associated with nervousness or social discomfort, while fidgeting may signal mild anxiety.

Correct Answer: B

Rationale: In caring for a client with borderline personality disorder, it is essential to set clear and consistent boundaries, use a firm, authoritative approach, and provide opportunities for the client to express feelings. Encouraging dependency can reinforce maladaptive behaviors, while avoiding discussing feelings can hinder therapeutic progress in addressing underlying issues. Building a sense of dependency may exacerbate the client's difficulties in developing autonomy and self-reliance, which are crucial for their progress and recovery. Therefore, encouraging dependency is not a recommended intervention in the plan of care for clients with borderline personality disorder.
