Which of the following requires immediate supervision in a chiropractic office?

Immediate supervision in a chiropractic office is necessary for tasks that involve direct patient interaction and care. Taking patient history falls within this category, as it involves gathering essential medical information and understanding the patient's health concerns, which is crucial for effective treatment planning. This task typically requires the presence of a licensed chiropractor to ensure that the information is accurately assessed and that any necessary follow-up actions are implemented according to ethical and legal standards.

In contrast, the other options involve supportive roles that do not require the same level of clinical oversight. Office administration tasks, marketing strategies, and insurance claim processing are more operational and can be performed independently by non-licensed staff. These functions do not necessitate immediate supervision because they do not directly impact patient care or require clinical judgement. Thus, taking patient history is the task that requires immediate supervision to maintain the quality of care and ensure compliance with regulatory guidelines in chiropractic practice.
