Correct Answer: D

Rationale: The correct answer is D because the inability to concentrate for extended periods is a key characteristic of ADHD. This behavior aligns with the inattention aspect of the disorder. Choice A is incorrect as separation anxiety does not directly relate to ADHD. Choice B could indicate oppositional behavior rather than ADHD. Choice C suggests sensory-seeking behavior, which is not a defining feature of ADHD.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): Multidisciplinary collaboration in therapeutic activities involves the input of professionals from various disciplines, leading to a holistic approach that considers all aspects of a patient's condition. This approach is more likely to result in better outcomes because it combines diverse perspectives, expertise, and skills to address complex patient needs comprehensively. Summary of Incorrect Choices: A: Reducing aggressive behavior is not the primary goal of multidisciplinary collaboration in therapeutic activities. B: While multidisciplinary collaboration may lead to efficient care, the primary focus is on achieving better outcomes rather than quicker discharge. D: Although improving staffing efficiency and resource allocation may be benefits of multidisciplinary collaboration, the main purpose is to enhance patient care outcomes through diverse perspectives and expertise.

Correct Answer: A

Rationale: Rationale for Correct Answer (A): Reporting the findings to the health care provider is the next best action because elevated BUN and creatinine levels indicate possible renal dysfunction, which could be causing the psychiatric symptoms. The health care provider needs this information to determine appropriate treatment and further evaluation. Summary of Incorrect Choices: B: Assessing the patient for a history of renal problems is not the next best action because the lab results already indicate potential renal issues. C: Assessing the patient’s family history for cardiac problems is irrelevant to the elevated BUN and creatinine levels and the psychiatric symptoms. D: Arranging for the patient’s hospitalization on the psychiatric unit is premature without addressing the underlying medical issue indicated by the lab results.

Correct Answer: C

Rationale: The priority nursing diagnosis in this case is C: Risk for suicide. This is because the patient is exhibiting suicidal ideation, which poses an immediate threat to their safety and well-being. Suicidal ideation requires urgent intervention to ensure the patient's safety. The patient's major depression, weight gain, and lack of symptom remission from the antidepressant medication further emphasize the seriousness of the situation. Choices A, B, and D are not the priority in this scenario as they do not address the immediate risk of harm to the patient. Imbalanced nutrition and chronic low self-esteem are important concerns but do not take precedence over the risk of suicide. Hopelessness, while relevant, is not as urgent as addressing the immediate risk of suicide.

Correct Answer: B

Rationale: The correct answer is B: Tourette’s disorder. The child's inability to sit still and jerking arms suggest motor tics, which are common in Tourette's disorder. Tourette's is characterized by involuntary repetitive movements or sounds. Choice A is incorrect as oppositional-defiant disorder does not involve physical tics. Choice C is a duplicate. Choice D is incorrect as it assumes defiance rather than considering a neurological explanation for the behavior.
