A Japanese male who is your patient in charge has just undergone his bilateral knee surgery.  You try and assist him in putting his anti-embolism stockings on and he winces and looks away, staring up at the ceiling. Your most appropriate response would be:

People of Asian descent, can sometimes be unemotional in connection with pain, so assessing their non-verbal language would be imperative. In order to let the nurse can administer pain meds as required, nursing assistants must mark any pain complaints from their patients to the nurse though they cannot perform official pain assessments. Telling your patient that you are proud of him – while this may be with the best of intentions on your part, it may come off as condescending and it may also prevent him from marking any future pain to you. Letting the nurse know that your patient needs pain medication or assuming that your patient is no longer experiencing any pain, are both situations where you are making assumptions about your patient without speaking directly to him.
