Which of the following activities is NOT included in the practice of funeral service?

Providing medical treatment to the deceased is not included in the practice of funeral service because funeral service professionals do not have the qualifications or authority to administer medical care. Their role is centered around handling the deceased after death, which includes tasks like preparing the body for burial or cremation, arranging funeral observances, and managing the necessary paperwork to comply with legal regulations.

In contrast, entering into contracts for pre-need dispositions, securing and filing documents related to the funeral process, and arranging funeral observances are all essential components of what funeral service professionals do. These activities involve planning for future funeral services, ensuring that all legal and regulatory paperwork is completed, and coordinating the specifics of the service itself, which are integral to the profession. Thus, option C stands out as the only activity unrelated to funeral service practice.
