❌ I came to the hospital because I want to receive a health checkup.
✅ I came to the hospital for a checkup / I came for a physical.
'receive a health checkup'은 길고 어색해요. 병원에서는 'for a checkup'이나 'for a physical'처럼 짧게 말해요.
잘못된 예: Hi, I came to the hospital today because I want to receive a health checkup.
올바른 예: Hi, I came to the hospital today for a routine checkup.
