Answer:
ask the client to sign a release without medical approval.
Explanation:
The only thing that the nurse needs to do is to ask the client to sign a release without medical approval. By signing this release the client accepts all the risks involved in leaving on their own without medical approval and releases the hospital and medical staff from any responsibility/liability. This is usually done when doctors/medical staff still need to perform more exams on the patient in order to make sure that they are in a healthy enough state to travel on their own but the patient wants to leave regardless of the doctor's warnings/disapproval.
