According to the ethical guidelines for behavior analysts specifically the Professional and Ethical Compliance Code for Behavior Analysts which covers competence and client welfare a BCBA must only accept clients for whom they have the appropriate time resources training and competency to provide effective services The text clearly states that Dr Smith has just enough time each month with her current caseload Accepting an additional high priority case without adjusting her current workload would likely compromise the quality of services for all her clients potentially leading to burnout inadequate supervision or rushed interventions Option A is inappropriate because discharging a client solely to take on another especially based on subjective need without a comprehensive transition plan is unethical Option B risks compromising the quality of services for all clients and violating the principle of responsible conduct Option D is strictly unethical as a BCBA is ultimately responsible for the clients treatment plan and supervision delegating primary case management to an RBT who is supervised personnel is not permissible and would violate the BCBAs ethical responsibilities regarding supervision and scope of practice Therefore the most ethical and appropriate action is to refuse the new case until she can ensure she has the capacity to provide highquality services which might involve reducing her current caseload or adjusting her schedule
