Answer:
Take a message to be returned as soon as possible.
Explanation:
Okay, in the question above we are given that someone or Physician because of an urgent question that came up has to make a phone call to another physician in another location but unfortunately the physician that the person called was busy and in the middle of a patient exam. The assistant of the physician that was called does should never interrupt his or her boss who is examining a patient at that moment but the assistant can just tell the physician that called that he or she should leave a message instead and he or she(that is the assistant) will relay the message to the office physician as soon as possible. That's a normal ethics of his or her work and the patient is important.
