A 15-year-old male who is mildly intellectually disabled is admitted to the adolescent unit because he repeatedly refuses to complete personal hygiene. The healthcare provider prescribes that the client brush his teeth three times a day. In the psychiatric team conference, a behavior modification program is recommended to engage the client's participation. When implementing this technique, which reinforcement is best for the practical nurse (PN) to provide?

A. Preferred activities or tokens for each compliance: Positive reinforcement, such as rewarding desired behavior with activities or tokens, is effective in behavior modification for intellectually disabled clients. B. Unit tasks for each omission of teeth brushing: This is a form of punishment and is not as effective in promoting long-term behavioral change as positive reinforcement. C. Candy for each successful hygiene task, like brushing his teeth: While it is a form of positive reinforcement, candy is not ideal due to the dental health focus of the task and potential nutritional concerns. D. Privilege restriction or fines for refusals to complete a hygienic task: Punitive measures are less effective and can increase resistance.
