Final answer:
The nurse should discuss substance use disorders, as alcohol-related DUI may indicate a broader pattern of substance abuse and related health concerns such as a history of depression.
Step-by-step explanation:
During a routine physical assessment, if a 27-year-old client acknowledges having their driver's license suspended due to an arrest for driving under the influence of alcohol, the nurse should discuss substance use disorders with the client in detail. This discussion could lead to exploring topics like the use of illegal drugs, since alcohol consumption, especially if it leads to legal issues such as a DUI, might indicate a broader pattern of substance abuse. Additionally, the nurse may want to inquire about any related history of depression or other mental health issues, as these can be both risk factors and consequences of substance abuse. While discussing unprotected sexual experiences or tendencies toward violent behavior may be relevant in certain contexts, the admission of a DUI suggests that the most immediate concerns involve substance use and potential dependency.
