Final answer:
Radiologic technologists are ethically bound to maintain patient confidentiality and cannot discuss a patient's clinical history with family members unless there is express consent from the patient.
Step-by-step explanation:
The question concerns the ethical conduct of radiologic technologists, specifically regarding the disclosure of patient information to family members. According to the American Registry of Radiologic Technologists (ARRT) Code of Ethics, the confidentiality of patient information is paramount. Radiologic technologists may not discuss a patient's clinical history with family members unless there is explicit consent from the patient or if legally mandated under specific circumstances. Therefore, the statement 'radiologic technologies may discuss a patient's clinical history with a family member' is generally false without patient consent.
