熱があるようですね。今すぐ看護師を呼んできますから、このままゆっくりしていてください。 — It seems you have a fever. I'll go get a nurse right now, so please stay still and rest. (Care · Emergency, Urgent to Senior, JLPT N4)

Gesture & etiquette

Place the back of your hand lightly on their forehead to confirm. Make eye contact. Point to the bed or chair: 'Stay right here.' Then leave promptly but calmly, jogging only once out of sight.

Announcing your action before leaving ('I'll go get a nurse') prevents the senior from feeling abandoned. The instruction to 'stay still' prevents them from getting up, which could cause a fall. Return within 90 seconds or send another person so the senior is never left alone for long.
