Final answer:
Your friend is likely experiencing depression if his doctor has recommended fluoxetine (Prozac) or sertraline (Zoloft). These medications are commonly used to treat depression. So the correct answer is option (B).
Step-by-step explanation:
If your friend's doctor has recommended fluoxetine (Prozac) or sertraline (Zoloft), it is likely that your friend is experiencing depression. These medications belong to a class called selective serotonin reuptake inhibitors (SSRIs), which are commonly used to treat depression. Major depression is a common mental disorder characterized by symptoms such as a severely depressed mood, loss of enjoyment in activities, changes in appetite and sleep, difficulty concentrating, and feelings of worthlessness.
SSRIs work by increasing levels of the neurotransmitter serotonin in the brain, which helps elevate mood and alleviate depression symptoms. It's important to note that these medications can also be prescribed for other conditions, such as certain anxiety disorders, but they are most commonly associated with the treatment of depression. If your friend has been prescribed one of these medications, it suggests that the healthcare provider is addressing symptoms related to depression.
