Final answer:
In an adolescent who is depressed and experiencing school difficulties, a nurse might expect additional problems such as anxiety disorders, behavioral difficulties, labile moods, and cognitive impairment.
Step-by-step explanation:
When an adolescent who is depressed and having difficulty in school is evaluated at a community mental health center, a nurse may expect additional problems beyond depression alone. Considering the connection between mental health disorders and educational struggles, the client might be experiencing several challenges. Among these is the potential for anxiety disorders, which, similar to depression, can cause significant impairments in concentration and memory, leading to academic difficulties. Behavioral difficulties are another comorbidity that might be observed due to the possible emergence of irritability, agitation, and disruptive conduct in the classroom setting. Furthermore, closely related to behavioral and emotional issues is labile moods, which are characteristic of mood disorders like bipolar disorder, and can interfere with a student's ability to maintain a consistent learning process. Lastly, while cognitive impairment is not typically the primary issue in cases of depression, the cognitive symptoms such as trouble concentrating, indecisiveness, and slowed processing can interfere significantly with academic performance, leading to difficulties in the educational setting.
