Executive dysfunction is commonly associated with which area of the brain?
Nucleus accumbens
Dorsolateral prefrontal cortex
Ventrolateral prefrontal cortex
Amygdala
The Correct Answer is B
Choice A reason: The nucleus accumbens is involved in reward processing and motivation, not higher-order executive function.
Choice B reason: The dorsolateral prefrontal cortex is critical for executive functions including planning, working memory, cognitive flexibility, and inhibitory control. Damage or dysfunction in this area manifests as difficulty organizing tasks, problem-solving, and regulating behavior.
Choice C reason: The ventrolateral prefrontal cortex contributes to inhibitory control and response selection but is less central to overall executive planning and working memory.
Choice D reason: The amygdala primarily processes emotional responses and fear learning, not executive function.

Correct Answer is D
Explanation
Choice A reason: While increased circulation is a proposed benefit of massage, the mechanism of anxiety reduction is more complex and involves nervous system modulation, not solely lymph flow or muscle tone.
Choice B reason: The idea of manipulating points of energy flow is not supported by scientific evidence; endorphin release may occur, but this description is oversimplified and partly inaccurate.
Choice C reason: The statement about crystalline deposits and energy flow is pseudoscientific and does not reflect physiologic mechanisms.
Choice D reason: Massage therapy has demonstrated physiologic effects including reductions in heart rate, blood pressure, and respiratory rate. Studies also show increased alpha brain wave activity, indicating relaxation, and decreased perceived anxiety. These responses reflect modulation of the autonomic nervous system and central nervous system, explaining the observed relaxation.
Correct Answer is C
Explanation
Choice A reason: A positive M-CHAT-R/F screen does not confirm a diagnosis of autism; it is a screening tool indicating the need for further evaluation.
Choice B reason: While developmental delay may exist, the screening result is not diagnostic for any condition.
Choice C reason: This is correct. A positive result indicates that the child should undergo a comprehensive developmental and behavioral evaluation to determine if ASD or other delays are present.
Choice D reason: ABA therapy is a treatment for confirmed autism but is premature without a definitive diagnosis following comprehensive assessment.
