Explanation: The correct answer is B. It would be important, before anything else is done, to rule out possible hearing impairment. It could certainly cause problems in the development of speech, and would compromise communication. Even if this is a case of autism, it would still be the first test before anything else is done. Mental retardation and hearing impairments are frequently seen in congenital disorders.A brain CT (choice A) should be done to rule out CNS lesions. The standard of care implies that cheaper and less invasive procedures need to be done first if they can rule out most common causes of the disorder. Thus, a hearing exam should be done first.A referral to a speech therapist (choice C) should be done after a probable diagnosis is established and further evaluation and speech rehabilitation needs to be done.Referral to a child psychiatrist (choice D) should be done after basic metabolic screening and other exams are done to rule out medical causes. It is certainly not the first thing to do.Thyroid stimulating hormone (choice E) levels should be checked in order to rule out a congenital deficiency. The fact that child has no signs of cretenism and that development has otherwise been normal, precludes the immediate need for these tests.
