Final answer:
J.G.'s alcohol use disorder is rated as severe due to his physical dependence, inability to fulfill responsibilities, health consequences, and admission laboratory results indicating chronic alcohol abuse.
Step-by-step explanation:
Based on the DSM-V criteria, J.G.’s alcohol use should be rated as severe. Several factors contribute to this assessment. J.G. has needed to drink more to achieve the desired effect, indicating tolerance, and has experienced withdrawal symptoms such as seizures, suggesting physical dependence. Additionally, his alcohol intake has caused significant impairment or distress, manifested in his inability to maintain a job and repeated hospital admissions for alcohol-related health issues, including gastrointestinal bleeding and altered mental status. Furthermore, J.G.’s admission laboratory work shows elevated liver enzymes (ALT, AST, and GGT), which could signal liver injury due to chronic alcohol abuse. His alcohol level upon admission was substantially high, reflecting acute intoxication. The combination of these clinical signs, symptoms, and behavioral impacts aligns with a severe rating for J.G.’s alcohol use disorder according to the DSM-V criteria.
