How does one differentiate factitious disorder from being thirsty w poor impulse control?

therealslimshady  If you're asking how to rule out diabetes insipidus, I think it's because: Diabetes insipidus is caused by a lack of ADH effect, so they will be peeing out too much water, thus making them dehydrated and hyperosmolar (thirsty). This CHF patient is presenting with signs of fluid overload +3  
an_improved_me  I think that ADH also has affects on central structures that increase thirst? Or is that only Angiotensin II? +

This is a BS question - I still picked the “right” answer because nothing else made sense, but this is not how this happens in real life. Having taken care of a million of these patients, they’re not trying to fake a disease or symptoms -> they’re thirsty and selfish with no ability to regulate their own behavior, and they throw temper tantrums and ring the call bell all day long asking for water - they’re definitely not hiding their water consumption. I’ve even seen people get desperate enough to drink out of the toilet because they’re “dying of thirst.”
