Children who show behavior characterized by characterized by a pattern of disobedient, hostile,
  and defiant behavior toward authority figures and along with the absence of a serious violation of
  the basic rights of others can be considered for the diagnosis of:

a) Conduct disorder
  b) Oppositional defiant disorder
  c) Antisocial personality disorder
  d) Intermittent explosive diso

When it is clear that a disruptive, impulse-control, and conduct disorder ought to be diagnosed,
  but the practitioner does not have enough information about the childs difficulties, the following
  diagnosis is assigned with the understanding that as more information becomes available, a more
  specific diagnosis can be made. It is:

a) Other specified disruptive, impulse-control, and conduct disorder
  b) Unspecified disruptive, impulse-control, and conduct disorder
  c) Pervasive developmental disorder
  d) None of the above

What are some signs that the practitioner would look for to determine that a person,
  usually a child, might have an elimination disorder?
