A child with ASD typically does not demonstrate which of the following?

A child with Autism Spectrum Disorder (ASD) does not typically exhibit a significant ejection murmur, as this finding is associated with certain cardiovascular conditions rather than a neurological or developmental disorder like ASD. An ejection murmur often indicates structural abnormalities of the heart, such as aortic or pulmonary stenosis, which are unrelated to the core characteristics of ASD.

In contrast, excessive fatigue, heart murmurs, and fever can occur in children with various health issues, including but not limited to those with ASD. Fatigue can arise from a variety of physical and psychological factors, heart murmurs can be innocent or symptomatic of other medical problems, and fever is a common response to infection or illness. Therefore, the absence of a significant ejection murmur in a child with ASD reflects the disorder's focus on behavioral and developmental aspects rather than physical heart structure or function.
