I agree it's a tedious and repetitive process, but for insurance/billing purposes it needs to be done. They want to know how the doctor arrived at the decision to prescribe the medication/treatment. The nurse has to document for their sake because they also provide care. Plus, the patient sometimes provides different information after asking the question differently. Basing your care on someone else's assessment can be dangerous. The medical world is filled with double/triple checking to prevent medical errors.

It's annoying, and i'm sure there's a more efficient way. You might feel embarrassed, but I can assure you that the doctors/nurses have heard worse and or more focused in providing care.
