Final answer:
The correct way to acquire patient information without consulting their chart is to ask the patient directly, which is both ethically and legally sound.
Step-by-step explanation:
The appropriate way to find out information on a patient without opening their chart is d) Ask the patient directly. Accessing a patient's social media, using their email, or opening their chart without consent violates patient privacy and confidentiality standards. Direct communication with the patient not only upholds ethical and legal medical practice but also allows for the most accurate and current information.
