A nurse is providing teaching to the parents of a 6-year-old child who is suspected to have attention deficit hyperactivity disorder (ADHD). Which of the following statements should the nurse make to describe the diagnostic process for ADHD?

A. "Most individuals with ASD are also diagnosed with Down syndrome, another developmental disorder.": Down syndrome is a separate genetic condition and is not commonly co-occurring with autism spectrum disorder. While comorbidities can exist, this is rare.

B. "Hypertension is a common co-morbid condition with ASD due to the stress associated with the disorder.": Hypertension is not typically associated with ASD in children. Stress may affect behavior, but it does not make hypertension a common comorbidity in this population.

C. "Often those with ASD also have sensory processing issues, which can affect their responses to certain textures, sounds, or lights.": Sensory processing differences are highly prevalent in individuals with ASD. These issues can manifest as hypersensitivity or hyposensitivity to sensory stimuli and are an important consideration in therapy, education, and daily care.

D. “Type 1 diabetes is a condition that is frequently found in conjunction with ASD.": Type 1 diabetes is an autoimmune condition that is not commonly associated with ASD. There is no established frequent co-occurrence between the two conditions.

A. "Speaking a different language at home shouldn't affect learning how letters sound.": Learning a second language can temporarily affect letter recognition and phonemic awareness in the new language. Dismissing the parent’s observation may create unnecessary concern and does not address the normal process of bilingual language acquisition.

B. "Children who are learning a new language sometimes have difficulty learning new letters.": Bilingual children may experience temporary delays in recognizing letters or sounds in a second language due to limited exposure and differences in phonetics. This response normalizes the experience and reassures the parent while encouraging continued support in both languages.

C. "It's great that you're teaching them another language at this age.": While promoting bilingualism is positive, this statement does not address the parent’s concern regarding letter recognition difficulties in English. It lacks guidance on supporting literacy development.

D. "You should have them evaluated by our speech team.": Referral is unnecessary at this stage unless there are broader concerns such as speech delays or communication disorders. Difficulty recognizing letters in a second language is often a normal part of bilingual learning.
