Final answer:
A medical assistant who takes a blood sample from a minor patient without parental consent is likely to face charges of Assault and Battery, as the minor cannot legally provide consent.
Step-by-step explanation:
If a medical assistant collects a blood sample from a minor patient without obtaining parental consent, they could most likely face charges for B. Assault and Battery. This is because performing a medical procedure without consent is considered a form of battery, and it is intensified by the fact that the patient is a minor and unable to give legal consent. The child's inability to provide consent is akin to lacking informed consent, which is a legal requirement for most medical procedures.
It's essential to note that while the medical assistant could be directly responsible for the act, any charges or claims of malpractice or negligence would typically form part of a civil proceeding rather than criminal charges. However, since the question specifically asks for criminal charges, assault and battery fit the scenario more closely than negligence or malpractice, which are usually dealt with in civil court. Consent from a parent or legal guardian is generally required for minors because they are not considered legally competent to make such decisions on their own.
