When I'm on the night shift, all the department heads can't sleep.

When the second-line emergency responders came over from the first consultation room, they were still holding the previous patient's medical record folder.

Qin Hai handed over the coagulation results and briefly explained the medical history he had just obtained:

"A 62-year-old woman, who had been taking warfarin long-term after surgery for lower limb thrombosis, missed a dose and overdosed. She took ibuprofen in the past four days, has had bleeding gums for a week, and blood-tinged nasal discharge. She hasn't mentioned black stools or hematuria yet. Her INR is 3.2, and her blood pressure was just measured at 145/82. Her family is on their way."

Lin Ye casually handed over the transparent bag containing the warfarin medicine box and the old medical record, as well as the triage record he had just written down, with key points marked with horizontal lines.

The second-line doctor flipped through the vascular surgery discharge record from last year's medical history, then glanced down at the aunt's gums. There were indeed faint red traces of bleeding. He nodded.

"Don't put them in the red zone for now, let's wait for the family members to arrive."

The aunt was still sitting on the blood collection chair, craning her neck to look at the emergency room entrance. Hearing this, she breathed a sigh of relief, but then started muttering, "Can I leave later? My old man is waiting at home. I've been out for so long, I'm not at ease."

As soon as she finished speaking, the automatic door at the emergency room entrance slid open, and a woman in a navy blue work uniform rushed in. Half of her hair was messy, a large wet patch was on the back of her T-shirt, and she was holding a half-empty bottle of mineral water in her hand.

Seeing her aunt sitting there, she took a couple of breaths before speaking: "Mom, I've finished feeding Dad, emptied the hot water bottle by the bedside, and the bedpan too. I've also switched the TV to the Peking Opera channel for him, so don't worry."

After saying this, her face immediately darkened, and she pointed at the transparent bag in the aunt's hand: "When I was cleaning your medicine box last week, I saw that you had stuffed an extra warfarin tablet in there. I've told you eight hundred times that you can't take this medicine without consulting a doctor, but you insisted it was fine. Now why are you at the hospital?"

The auntie stubbornly backed away, saying, "I'm just feeling dizzy. I was just going to get some blood pressure medication and leave, but this doctor insisted I stay, drawing blood and making phone calls. I was worried I'd be late for work and lose my attendance bonus!"

"So what if you lose your perfect attendance bonus? Losing your perfect attendance bonus is still better than you fainting at home and nobody knowing!" The daughter's voice rose a little, her eyes reddening. "If something really happens to you, who will take care of my dad?"

Lin Ye quickly went over to smooth things over: "Don't worry, there's no sign of heavy bleeding yet, but the indicators are a bit high. Don't add any more medication tonight, and don't take any more painkillers like ibuprofen."

He paused for a moment, then said, "Take your mother to the vascular surgery department where she used to get her medication, or to a specialized anticoagulation clinic for a follow-up appointment tomorrow. Bring all her usual medications in their original packaging, along with her old medical records and today's test results, so the doctor can decide how to proceed."

The second-line emergency room doctor added, "If you experience black stools, vomiting blood, or uncontrollable nosebleeds after going home, come to the emergency room immediately. Otherwise, just go to the outpatient clinic tomorrow. Don't worry too much."

The daughter frowned as she flipped through the test results, then looked troubled again: "Our company is having an audit tomorrow, and everyone has to be on duty. I can't take time off at all, and I don't trust my mom to go alone."

"I can go by myself!" the auntie immediately replied. "I know the way. Didn't I go get my medicine by myself last time? You go to work, don't worry about me."

"That won't do. You won't be able to explain to the doctor how much medicine you took."

Lin Ye thought for a moment and offered them a practical solution:

"You can try to schedule an appointment for your aunt's anticoagulation clinic tomorrow on your phone. If you can't get an appointment, then book one with the vascular surgery department where she usually gets her medication. Also, take clear pictures of today's test results and show them to the doctor tomorrow. If you really can't get time off work, ask a relative or neighbor first, and make sure your aunt doesn't go alone."

The daughter quickly took out her phone to write it down: "Okay, I'll make an appointment first. I'll ask my cousin tonight to see if she can come with me tomorrow."

The two chatted about the details for a bit more, and the aunt stopped making a fuss about leaving, instead sitting there obediently listening while clutching the sealed bag.

Ma Hao was standing to the side, and he wanted to say something sarcastic, but when he looked up and saw that the mother and daughter's eyes were red, he quickly swallowed his words and turned around to organize the blood collection tubes piled on the triage table.

Nurse Zhu knocked on the window glass, her clear voice cutting through the noise of the waiting area: "Number 37, go to consultation room one. Number 38, get ready. Take your number slips and move forward only when your number is called on the screen. Don't all block the window."

The queuing crowd, which had been whispering just moments before, immediately fell silent.

The mother and daughter thanked him again, and the daughter helped the woman slowly walk towards the emergency room entrance. The woman took a few steps and turned back, raising the transparent bag in her hand to Lin Ye: "Young man, thank you for your help. I'll have her bring the medicine box tomorrow."

Lin Ye smiled and nodded at her.

As soon as Lin Ye left, Qin Hai came over with a thermos and tapped the rotation manual on the triage desk: "Finish all the teaching signatures and submit them to the Department of Science and Education before next week. Don't wait until the last day to have them piled up. Didn't you still find the teaching signatures for the two postoperative cases you rotated through surgery last month?"

Lin Ye paused for a moment before remembering what had happened. During his previous surgical rotations, he was constantly running between the wards and the operating room. He finished writing the medical records but forgot to look for the supervising doctor's signature. Later, when he transferred to the emergency department, he forgot about it again. Those two pages are still blank.

"Yes, I don't have a shift tomorrow afternoon. I'll go to the surgical office to get Director Wang's signature."

"Just don't forget. The Science and Education Department has been urging you three times last week. If you don't hand it in, it will affect your graduation assessment." Qin Hai took a sip of hot water, turned and walked towards the clinic area, then turned back after a couple of steps. "You better remember, kid. Don't forget again."

After Qin Hai left, Ma Hao came over and stuffed a thick stack of printed review materials into Lin Ye's arms. The edges of the papers were still warm from being printed.

"The theory exam is on the 15th of next month. I got the past three years' exam questions from a senior student and printed them out for you. Brother Ye, don't just focus on the patients, you have to help yourself too. It would be a real shame if you got stuck on the theory."

Lin Ye took the materials, feeling a warmth in his heart. He had been focusing on triage and medical records every day lately, almost forgetting about the theoretical exam.

He took out the rotation manual from his white coat pocket, turned to the two blank pages, and the surgical teaching signature column was still empty. He was thinking about how to tell Director Wang when he went to the surgery department tomorrow when the triage station's call button suddenly went off. Nurse Zhu's voice came over: "Lin Ye, please take the temperature of number 39. He just came in from outside and has a slight fever."

Lin Ye quickly stuffed the rotation manual back into his pocket, put the review materials in the triage desk drawer, picked up the temperature gun and went over.
