Correct Answer: A

Rationale: The correct answer is A. Psychiatrists use the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) published by the American Psychiatric Association (APA) to determine diagnoses. The DSM-5 provides standardized criteria for the classification of mental disorders, ensuring accurate and reliable diagnosis and treatment. Choices B and D are inaccurate as hospital policy does not dictate psychiatric diagnoses, and the American Medical Association is not responsible for psychiatric diagnostic criteria. Choice C describes a more general approach to assessment and does not specifically address the standardized criteria used in psychiatric diagnosis.

Correct Answer: B

Rationale: The correct answer is B: Awareness of factors creating stress. In managing anxiety, the first crucial step is recognizing and being aware of the factors that contribute to stress. Without this awareness, it becomes challenging to effectively address and manage anxiety. Diagnostic blood tests are not typically the initial step in managing anxiety; they may be used to rule out other medical conditions but are not the primary focus. While relaxation exercises can be helpful in managing anxiety, understanding the root causes of stress takes precedence. Identifying support systems is important but comes after recognizing the stress factors to develop a comprehensive management plan.

Correct Answer: B

Rationale: Excessive worry is a primary characteristic of generalized anxiety disorder (GAD). Patients with GAD experience persistent and excessive worry about various aspects of their lives, often anticipating disaster or catastrophic outcomes. This worry is difficult to control and can be accompanied by physical symptoms like restlessness, fatigue, irritability, muscle tension, and difficulty concentrating. Flashbacks are more commonly associated with post-traumatic stress disorder (PTSD), hallucinations are more typical of psychotic disorders, and compulsive behaviors are characteristic of obsessive-compulsive disorder (OCD). Therefore, when assessing a patient with GAD, a nurse would most likely observe excessive worry.

Correct Answer: D

Rationale: The nurse should recognize the client's statement 'I don't drink too much!' as the use of the defense mechanism of denial. This response indicates the client's refusal to acknowledge the reality of excessive alcohol consumption, which is a key characteristic of denial. By denying the problem, the client avoids facing the negative consequences and feelings associated with their alcohol abuse. Choices A, B, and C do not exhibit denial but rather represent different defense mechanisms. Hiding liquor bottles in a closet might indicate the defense mechanism of concealment, yelling at their son for slouching in his chair could reflect displacement, and burning dinner on purpose might suggest passive-aggressive behavior.

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.
