Administering the NRS is straightforward. Nurses should ask the patient to rate their pain on a scale of 0 to 10. It's important to ensure the patient understands that 0 means no pain and 10 means the worst pain imaginable. Nurses should also consider the patient's cognitive ability and provide additional explanations if needed. For example, saying, "On a scale of 0 to 10, with 0 being no pain and 10 being the worst pain you can imagine, how would you rate your pain right now?"
