Are there any situations when a physician is justified in lying to a patient?

"I understand that the only reason a physician should withhold information from a patient is under the premise of therapeutic privilege. This concept describes situations where a patient could be a threat to themselves if the physician fully disclosed the details of their medical situation. Although there is support for this idea, it should not be exercised unless the case is extreme. Physicians have a fiduciary duty to their patients, which must be taken seriously. Honesty is always the best policy when discussing matters with patients."

Prepare a well-versed answer for this question, as it may come up many times during medical school and your career. Research the concept of 'therapeutic privilege' and then create your response. Your answer should be brief, clear, and not convoluted.
