Final answer:
The patient's admission is for detoxification from alcohol and barbiturate intoxication, as well as management of cirrhosis of the liver.
Step-by-step explanation:
The reason for the patient's admission is 1) Detoxification from alcohol and barbiturate intoxication.
A person with chronic alcoholism and barbiturate abuse may require medical supervision and support during the detoxification process due to the aversive and potentially life-threatening withdrawal symptoms associated with these substances.
In addition, the patient's cirrhosis of the liver, which is a complication of alcoholism, may require management during their stay at the acute care facility.
