text: can a colonoscopy be done on some one who is dehydrated and in the hospital? we have been trying to get this person to have one for a long time., and i am suggesting that it be done while they are in the hospital, because once they get out the will find excuses not to have it done.    also if there is a nurse in the family, are they allowed to be attending to the family member while tha family member is in the hospital.  i know that doctors have a rule about being assigned to family members.
