"I don't think we should give her sleeping pills. She has a slight pain in her abdomen now. If the pain suddenly becomes severe, sleeping pills won't be appropriate," Xie Wanying said.
"Does she have abdominal pain? Is she a tumor patient?"
"Yes, a tumor, colorectal cancer."
"Is it an intestinal obstruction?"
"No, not yet," Xie Wanying said.
"Can't we give her painkillers?" Sun Yubo thought again.
"Teacher Sun." Xie Wanying nodded to the teacher's words, "We can't give her painkillers. If the tumor suddenly bleeds or there is an intestinal obstruction, it's not right to give the patient painkillers."
Sun Yubo felt a chill in his heart: what the student said alarmed him. He did not want such a scene to occur tonight.
