Correct Answer: D

Rationale: Symptoms of major depressive disorder include a loss of interest or pleasure, decreased ability to concentrate, significant weight loss or gain, and feelings of worthlessness or excessive guilt. Increased energy is not typically associated with major depressive disorder; instead, fatigue is more common. Clients with major depressive disorder often experience a lack of energy, motivation, or enthusiasm, leading to feelings of lethargy and fatigue. Therefore, increased energy is an atypical symptom in major depressive disorder, making it the correct answer.

Correct Answer: C

Rationale: The correct answer is C, 'Mindfulness meditation.' Side effects of antipsychotic medications include tardive dyskinesia, neuroleptic malignant syndrome, orthostatic hypotension, and hyperglycemia. Mindfulness meditation is not a side effect of antipsychotic medications. Choices A, B, and D are all potential side effects of antipsychotic medications. Tardive dyskinesia is a movement disorder characterized by repetitive, involuntary movements. Neuroleptic malignant syndrome is a rare but life-threatening reaction to antipsychotic medication. Hyperglycemia can occur as a side effect of some antipsychotic medications, particularly the second-generation ones.

Correct Answer: A

Rationale: For a client with OCD performing ritualistic handwashing, the nurse should initially allow the client to continue the behavior. Abruptly stopping the behavior or providing a distraction can heighten the client's anxiety. Encouraging the client to perform the ritual more quickly does not address the underlying issue of OCD and may exacerbate their anxiety. Providing a distraction to interrupt the ritual may not be effective in the long term and could lead to increased distress. Gradual limits should be established over time to help the client manage and reduce the ritualistic behavior effectively.

Correct Answer: D

Rationale: In a client diagnosed with anorexia nervosa, expected findings include amenorrhea, lanugo, hypotension, and bradycardia. Hyperkalemia is not typically associated with anorexia nervosa; instead, hypokalemia, which is low potassium levels, is more common. Hypokalemia can result from decreased intake of potassium-rich foods or excessive purging behaviors commonly seen in individuals with anorexia nervosa.

Correct Answer: A

Rationale: The correct evaluation is that defense mechanisms can be self-protective responses to stress and do not necessarily need to be eliminated. These mechanisms serve the purpose of reducing anxiety during times of stress. While some defense mechanisms may be maladaptive, they can also help individuals cope with challenging situations. It is essential for the nurse to recognize that addressing defense mechanisms should be done sensitively, as they may be crucial for the client's emotional regulation. Encouraging the development of healthy coping skills while acknowledging the role of defense mechanisms in managing stress is a balanced approach in psychiatric care. Choice B is incorrect because completely eliminating defense mechanisms is not always feasible or beneficial. Choice C is incorrect as it oversimplifies the relationship between defense mechanisms and ego integrity. Choice D is incorrect as it misrepresents the role of defense mechanisms in ego functions.
