Review Question - QID 216738

A 6-year-old boy is brought into the clinic by his mother for behavioral concerns. His mother states that he started elementary school 3 months ago. However, for the past 2 months, she has been concerned that he has had attention issues at school. His teacher called her family last week to report that he often ignores her and other children during group learning activities because he is busy "daydreaming." His mother reports that she has also noticed this behavior, such as during dinner when he stops eating, stares blankly ahead, and blinks rapidly. These episodes occur multiple times a day and reportedly last about 15 seconds, but then he resumes his activities as normal. His mother states that he was born via uncomplicated cesarean section at 39 weeks of gestation and has met all developmental milestones since. His temperature is 98°F (36.7°C), blood pressure is 110/70 mmHg, pulse is 90/min, and respirations are 15/min. On examination, he is talkative and playful with normal cranial nerve examination, strength, and reflexes throughout. He interacts with the physician appropriately and maintains eye contact. Which of the following is most likely to improve this patient's symptoms?
