A caregiver brings a 15-year-old male client (pronouns: he/him/his) to the primary healthcare provider for evaluation. The caregiver reports that the client was an active, happy teenager who used to enjoy going to school, participating in extracurricular activities, and spending time with his friends. Lately, the client is moody, sleeps a great deal, and does not seem to want to go anywhere other than his room. The caregiver reports daily frustration and arguments between them, "constantly fighting to get him to go to school and do his homework." The healthcare provider diagnoses the client with depression and places him on 25 mg of sertraline once a day. After 10 days, the client's caregiver calls and reports that the client has started being angry, argumentative, easily agitated, and seems to be more secretive. What should the nurse recommend to the caregiver?
A. Increase the dosage to 50 mg once a day.
B. Stop taking the medication immediately without weaning.
C. Continue taking the dosage as prescribed.
D. Return to the office today for reevaluation.
