Final answer:

Step-by-step explanation:
When caring for patients with dementia, the most appropriate nursing intervention is to give simple directions, focusing on one thing at a time. This is because individuals with dementia often have difficulty processing and retaining complex information.
By providing clear and concise instructions, the patient is more likely to understand and follow the directions. For example, instead of saying 'Please go to your room, take your medication, and then join us for dinner', the nurse can say 'Please go to your room' and once the patient has done that, given the next instruction.
