Final answer:
Family members can help control behavior changes in a stroke patient with right-sided hemiplegia by providing verbal instructions in small steps.
Step-by-step explanation:
When a patient has a right-sided hemiplegia due to a stroke, the nurse can teach family members to help control behavior changes by providing directions to the patient verbally in small steps. By breaking down instructions into smaller, manageable tasks, the patient can better understand and follow them. This can help the patient feel more independent and capable while also preventing frustration and confusion.
