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

When Nurse Zhu returned pushing the observation cart, Luo Jing was staring blankly at her wrist.

The small patch of wind that had previously bulged up was still there, but its edges had not spread outwards.

She held a tissue in her right hand, but because she was so itchy, she only dared to hold it loosely and didn't dare to press it hard.

"Is it time?"

"It's time." Nurse Zhu deftly wrapped the cuff. "Relax your hand and don't speak yet."

Nurse Zhu then clipped the finger-clip pulse oximeter onto her right index finger.

As the blood pressure monitor slowly inflated, Luo Jing held her arm still, not daring to move, but her gaze remained fixed on the swollen area on her wrist.

When the cuff loosened with a "hiss," Nurse Zhu glanced at the readings on both sides: "122, 76, heart rate 88, blood oxygen 99, all quite stable."

Ma Hao walked over from the workstation, first looked at the color of her lips, and then gestured for her to roll up her sleeves.

The patches of red that were originally connected on my forearm have dispersed, and the most intense red patches in the middle have faded considerably.

A faint red mark still lingered on the side of her neck, but Luo Jing stopped tugging at her collar and rubbing her neck.

"How did you feel during that half hour?"

"Much better." Luo Jing pointed to the inside of her wrist. "This area is still itchy, but the rest of the body is fine."

Ma Hao looked down and wrote down the vital signs and changes in the rash in the half-hour column of the observation form. He then added a sentence after the "wheal on the wrist" line: "The area has not expanded further."

Luo Jing leaned over for a glance, her tone tinged with anticipation: "Can I leave now? Look, I'm not scratching much anymore."

"Not yet." Ma Hao clipped the observation form back onto the splint next to him. "A new patch appeared after you took the medication, so you need to stay for observation for at least a full hour. It's just that it hasn't gotten worse yet, but that doesn't mean the observation is over."

"Oh? We have to wait another half hour?" Luo Jing was a little disappointed.

"Sit a little longer. If there are no new changes by the time it's time, I'll come back immediately for a follow-up check."

Luo Jing leaned back in her chair and picked up her phone to swipe.

My husband just sent me a photo: our daughter is sitting in the back seat of the car with her schoolbag on her back, and she is also holding a thermos tightly in her arms.

The following line reads: "I've picked up the child. I'll take her to your mother's first, then go to the hospital to pick you up."

She quickly replied "okay" and put her phone on her lap: "Okay, I'll wait for him to come over, so I don't have to take a taxi later."

Just then, the call number light for consultation room number two came on.

Nurse Zhu glanced towards the door: "The next patient has arrived."

Ma Hao checked the medication time on the observation sheet and then glanced at the clock in the lower right corner of the workstation.

"We'll be at the follow-up appointment in about twenty minutes." He turned the observation sheet toward Nurse Zhu. "The wound on your wrist hasn't spread anymore. If she presses the call button, please let me know."

"Okay, you can go back to your work." Nurse Zhu moved the call bell closer to Luo Jing. "If you feel unwell, just press this. Don't get up and run around by yourself."

Ma Hao then turned and walked towards consultation room number two.

On the other side of the partition, the patient in bed five had just come out of the examination room with his discharge form in hand.

After Lin Ye submitted the medical record, he looked up and saw Ma Hao leading the next patient into consultation room number two.

Both consultation rooms quickly became busy.

At first, Luo Jing would glance at her phone every few minutes, but later she simply placed it face down on her lap.

When her husband sent her the message "I'm at the hospital entrance," it was five minutes before the one-hour mark for taking her medication was up.

Luo Jing replied, "I'll come out after my follow-up examination," and remained calmly seated in the observation chair.

She raised her hand and touched the side of her neck through her collar, her fingertips pausing for two seconds: "It seems to have subsided here."

Nurse Zhu pushed the observation cart in front of her: "The doctor will come and examine you together in a bit, don't rush."

After Ma Hao finished writing the test order for the patient in consultation room number two, he watched the patient take the order and leave, then walked back to the observation station right on time.

"Come on, let's take another look at the situation."

Luo Jing immediately rolled up her sleeves.

The bulge on her wrist had mostly collapsed, leaving only a faint red mark.

The swollen areas on my forearm have all flattened out.

She lifted her hem a little more to look at her waist. The first few marks were still there, but the color was much lighter than it had been half an hour ago.

"Has any new growth occurred in the past half hour?"

"I haven't seen anything new." Luo Jing lowered her clothes. "It's still a little itchy, but I can bear it, unlike when I first arrived, when I felt uncomfortable if I didn't scratch."

Ma Hao then checked her lips and listened to her lungs with a stethoscope. He didn't hear any wheezing, so he signaled to Nurse Zhu to recheck her blood pressure and blood oxygen levels.

Nurse Zhu re-clamped the pulse oximeter and waited for the readings to stabilize before loosening the cuff: "120, 75, heart rate 84, oxygen 99. Similar to last time, all stable."

Ma Hao entered the results of the one-hour follow-up examination into the observation record and got up to find Qin Hai.

Qin Hai had just come out of another consultation room and followed him to the workstation to sit down.

Ma Hao put the initial medical record and the two observation records on the same screen.

Qin Hai read it from beginning to end, pausing for a few seconds on the lines for "medication time" and "new urticaria on the wrist".

"Has the discharge prescription been issued?"

"Not yet, wait until you finish reading."

"She can leave the hospital." Qin Hai released the mouse. "Make sure you explain the medication and return-to-hospital arrangements clearly, and complete the discharge record."

Ma Hao replied "Okay" and turned to walk back to Luo Jing's side.

Her husband was already waiting outside the emergency room, so Luo Jing wasn't in a hurry anymore.

She put her bag down at her feet and listened attentively as Ma Hao explained the medication schedule for the evening.

"Doctor, I still have a few rashes on my waist that haven't completely disappeared. Will it really go back to normal?" She was still a little worried.

"You don't need to wait until every patch is completely gone." Ma Hao handed her the prescription and discharge form. "There are no new lesions now, the itching has lessened, and your blood pressure and breathing are stable. Just go home and take the medication as prescribed. But you still need to be extra careful tonight."

Luo Jing took the discharge form and stared at the medication section first.

"You've already taken your medication once today, so don't increase the dosage tonight." Ma Hao waited for her to find the corresponding item before continuing, "Don't touch that yogurt you drank before, and don't use it for experiments. Also, don't drive yourself tonight."

He paused, then emphasized, "If your lips or tongue are swollen, you can't breathe, or you suddenly feel dizzy, have a stomachache, or vomit after you get back, go to the hospital immediately. If it's an emergency, call 120 right away. Don't try to tough it out."

Luo Jing flipped the discharge form to the back and glanced at it: "Do I need to come back for a follow-up check-up tomorrow?"

"The rash has completely subsided and hasn't recurred, so I'll continue taking the medication as prescribed." Ma Hao pointed to the outpatient information section on the prescription. "If new rashes appear in bursts tomorrow, or if they flare up again after I stop taking the medication, I'll go to the dermatology or allergy clinic for further examination."

"Okay, I'll take a picture and save it, so I don't forget it as soon as I get home."

Luo Jing aligned the prescription and discharge form, took a picture, and sent it to her husband.

Ma Hao waited until she had packed her things before ending the observation order in the hospital's system and adding the discharge time.

After Luo Jing left, he submitted the complete medical records to Qin Hai for review, and then took out the assessment form from the drawer.

After reviewing the newly added discharge record, Qin Hai picked up a pen and signed his name and the date in the second blank space.

"This case will be included in your count too."

Ma Hao took the form, glanced at the neat signature, put it back in the transparent file bag, sealed it, and placed it deep in the drawer.

Just then, half a body peeked into the doorway of examination room number two: "Doctor, is it my turn yet?"

Ma Hao had already opened the next triage form: "It's your turn, please come in."
