Final answer:
The PCT should politely decline to provide any information about the patient's test results to the coworker, adhering to HIPAA privacy rules and protecting the patient's confidentiality.
Step-by-step explanation:
The appropriate response for a Patient Care Technician (PCT) when approached by someone like a patient's coworker asking about the patient's medical information is to maintain confidentiality according to the Health Insurance Portability and Accountability Act (HIPAA). Even if a patient is in stable condition, it's crucial to protect their privacy. Hence, the correct action for a PCT is to politely decline to provide any information.
If the coworker persists, the PCT should reiterate the importance of patient privacy and suggest that the coworker speak directly to the patient about their health information, if the patient wishes to share it. Under no circumstances should the PCT divulge any patient information to unauthorized individuals, including coworkers, family members, or friends, regardless of the patient's health condition.
