Final answer:
As an RBT, if you notice your client is drowsy and engaging in novel behaviors, it is important to ensure their safety and redirect their attention.
Step-by-step explanation:
As an RBT (Registered Behavior Technician), if you notice that your client is drowsy and engaging in novel behaviors during an in-home session, it is important to take appropriate action. One approach would be to first ensure the safety of the client by removing any objects or activities that may be dangerous. Then, you should gently try to redirect the client's attention towards a more appropriate and engaging activity. It may also be helpful to communicate with the client's parents or guardians to determine if there are any underlying factors contributing to the drowsiness, such as lack of sleep or medication side effects.
