A 3-year-old boy undergoes evaluation for autism spectrum disorder (ASD). The PMHNP conducting the examination utilizes a tool with four modules to aid in diagnosis. Which of the following is the PMHNP's tool?
Modified Checklist for Autism in Toddlers (M-CHAT)
Ages and Stages Questionnaires (ASQ)
Children’s Behavior Checklist
Autism Diagnostic Observation Schedule (ADOS)
The Correct Answer is D
Choice A reason: The M-CHAT is a screening tool designed to identify risk for ASD in toddlers, but it is not a diagnostic instrument with multiple modules.
Choice B reason: Ages and Stages Questionnaires assess developmental milestones broadly and are not specific to autism diagnosis.
Choice C reason: Children’s Behavior Checklist is a general behavioral assessment tool and does not provide module-based diagnostic evaluation for ASD.
Choice D reason: The ADOS is a structured diagnostic tool with four modules tailored to age and language level, widely used for formal assessment and diagnosis of autism spectrum disorder.

Correct Answer is C
Explanation
Choice A reason: M-CHAT screens specifically for autism risk in toddlers but does not assess broader developmental domains.
Choice B reason: ADOS is a diagnostic tool for autism, not a general early developmental screening tool for clinic-wide use.
Choice C reason: The ASQ is a comprehensive developmental screening tool that identifies children with delays or disorders across multiple domains before school age, ideal for early intervention planning.
Choice D reason: Connors Parent Rating Scale assesses ADHD symptoms but does not screen for overall early developmental delays.
Correct Answer is B
Explanation
Choice A reason: Acute stress disorder occurs within the first month after a traumatic event, and this scenario involves emotional response to a life transition rather than trauma.
Choice B reason: Adjustment disorder is characterized by emotional or behavioral symptoms in response to identifiable stressors, such as relocation or life changes, occurring within three months of the stressor. The timing and context of her symptoms fit this diagnosis.
Choice C reason: Conversion disorder involves neurological symptoms without a medical cause and is unrelated to crying spells in response to stressors.
Choice D reason: PTSD requires exposure to a traumatic event involving threat to life or safety, which is not present in this scenario.
