Final answer:
Child abuse can be considered ambiguous in cases of psychological maltreatment, abuse by non-family members, and medical neglect.
Step-by-step explanation:
Child abuse can be considered ambiguous in several cases. One example is when the abuse involves psychological maltreatment, which may not leave physical evidence and can be difficult to prove. Another example is when the abuse is perpetrated by someone who is not a parent or relative, as it may be harder to identify and address. Additionally, cases of medical neglect can be ambiguous as the line between neglect and different parenting styles or cultural practices can sometimes be blurry.
