A 22-year-old woman recently began treatment with fluoxetine (Prozac) for major depressive disorder. She now exhibits symptoms of mania. She completes the Young Mania Rating Scale (YMRS) and her score is 25. What does this indicate?

Choice A reason: This choice is correct because a YMRS score of 20–29 indicates moderate mania, reflecting significant mood elevation, increased activity, and behavioral disturbances that require monitoring and possibly treatment adjustment. Choice B reason: Mild mania corresponds to YMRS scores of 12–19, indicating less pronounced symptoms than observed in this patient. Choice C reason: Severe mania corresponds to YMRS scores of 30 or higher, which would reflect extreme agitation, psychosis, or risk to self/others. Choice D reason: Minimal mania corresponds to YMRS scores below 12, which does not match the patient’s clinical presentation or score of 25.
