At the hospital's emergency room, Li's mother had her temperature taken, which wasn't very high, but she vomited several times on the spot, and was diagnosed with acute gastroenteritis. The doctor prescribed an intravenous medication.
In the infusion area, a young nurse pushed a treatment cart over to help Li's mother with the infusion. Li's mother, having vomited several times, was slightly dehydrated, making her veins difficult to locate—they were not only deep but also brittle. Even if the needle hit the vein, it could cause the vein to rupture and swell immediately. After two consecutive needle insertions that caused swelling in Li's mother's hand, the young nurse dared not continue on her own and called an experienced nurse for assistance. The old nurse grasped Li's mother's forearms, feeling around heavily, and candidly stated: It's difficult to insert.
