Final answer:
A CPCT should respond to questions about a patient's roommate by politely refusing to give information, citing patient privacy regulations like HIPAA.
Step-by-step explanation:
A CPCT (Certified Patient Care Technician) must adhere to patient privacy regulations, such as the Health Insurance Portability and Accountability Act (HIPAA). When asked about the health of a patient's roommate, the CPCT should provide an appropriate response that protects the roommate's privacy. An example of a suitable response would be: "I'm sorry, but I'm not able to discuss the health of any patient other than your family member due to confidentiality policies. If you have any questions about your mother's health, though, I would be happy to discuss them with you."
