Sent to the countryside, I turned the health center into a top-tier hospital.

"Come here one by one, I'll take your pulse."

Without wasting any words, Chen Ping took the pulses of the five people in turn.

After some investigation, it was found that Zhang Lei, Wang Hao, Liu Zixuan, and Xia Yutong simply suffered from cold in their bodies and gastrointestinal spasms. The problem was not serious and could be relieved by applying heat, resting, and simple conditioning.

The last one, Li Mengmeng, was clearly in a much more serious condition.

She was physically weak, timid, and had a delicate stomach. At this moment, her face was as pale as paper, her forehead was burning hot, she was not only suffering from persistent abdominal pain, but also had a low-grade fever, and her pulse was floating, tight, and disordered.

This is a typical case of acute enteritis caused by ingesting untreated water, accompanied by a cold.

"Nonsense."

Chen Ping frowned. "The mountain water looks clean, with bacteria and parasite eggs invisible to the naked eye. Your digestive systems are delicate; how dare you drink it directly?"

The group hung their heads, their faces full of regret, too pained to even apologize.

Chen Ping didn't dare to delay and immediately opened a ward, letting the group sit inside.

Chen Ping carefully took Li Mengmeng's pulse again.

"A floating, rapid, and tight pulse is a typical sign of cold-dampness affecting the spleen and stagnation of qi in the stomach and intestines."

Chen Ping frowned, then said, "Lift up your shirt..."

Li Mengmeng was taken aback, then looked at the other boys in the room.

"Just lift your shirt, you don't need to take off your bra, it's fine!"

Chen Pingan patted Li Mengmeng and said.

Li Mengmeng lifted up her hoodie, revealing her fair belly.

Chen Ping then reached out and gently pressed her upper abdomen, around her navel, and lower abdomen, observing her reaction as he pressed.

When Li Mengmeng pressed her fingertips against her stomach area, she only frowned slightly.

When the pressure was applied around her navel, she instantly winced in pain, let out a muffled groan, and instinctively pulled her abdomen in to resist.

"There is significant tenderness around the navel, but no rebound tenderness or abdominal muscle stiffness."

Chen Ping moved gently, pressing and saying, "Appendicitis, intestinal perforation, and peritonitis are ruled out."

Once the diagnosis was confirmed, he immediately began treatment.

First, physical methods were used to reduce the fever, such as wiping Li Mengmeng's forehead, neck, wrists, and ankles with warm medicated towels. Physical methods of dissipating heat do not harm patients with weak constitutions.

Then, she took out silver needles and skillfully inserted them quickly and accurately into several acupoints, including Zusanli, Zhongwan, Tianshu, and Qihai.

The silver needles are inserted into the body and gently twisted to tonify or purge, with the aim of warming the middle jiao, dispelling cold, regulating qi, relieving pain, and harmonizing the stomach and intestines.

While administering acupuncture, Chen Ping turned around to prepare the medicine, selecting several commonly used Chinese herbs such as agastache, perilla, poria, atractylodes macrocephala, dried ginger, and coptis chinensis.

The formula is mild and specifically designed for acute gastroenteritis caused by cold and raw stimuli, dispelling cold and dampness, and relieving diarrhea.

The hospital always keeps ready-to-use granules, saving the trouble of decocting medicine. Chen Ping mixed them with warm water, let them cool to lukewarm temperature, carefully helped the weak Li Mengmeng up, and fed them to her little by little.

The entire process is reliable, standardized, and targeted, without any frills; it uses only the most practical diagnostic and treatment methods available to primary care facilities.

The effect was immediate in just twenty minutes.

The feverish forehead temperature gradually subsided, and Li Mengmeng's tense body began to relax.

The cold sweat stopped, the recurring abdominal cramps decreased significantly, and I was able to breathe steadily, no longer feeling weak and trembling.

The four students next to him watched intently, forgetting their stomach pain, and propped themselves up, watching Chen Ping operate the machine attentively.

Once Li Mengmeng had completely calmed down and was leaning back in her chair to slowly regulate her breathing, Chen Ping wiped his hands and turned to look at the group.

"Watch closely and remember this well."

Chen Ping spoke in a serious tone, displaying the rigorous demeanor of a supervising teacher: "In rural towns and villages, when making house calls, there are often no blood tests, no color Doppler ultrasounds, no CT scans, and we can't rely on any equipment."

"At times like this, you can't just wait for the instruments; you have to rely on your eyes, your hands, and your medical history to make a purely clinical judgment. This is the most life-saving skill you medical students can have."

"Although you are studying nursing, you still need to know these things. A nurse who doesn't want to be a doctor is not a good nurse."

The four of them immediately sat up straight, listened intently, and dared not let their minds wander for even a moment.

Even Li Mengmeng straightened up and listened carefully.

Such immersive explanations are truly rare.

"Let's start with today's most typical case: acute gastroenteritis caused by eating raw, cold, or unclean food."

"First, look at the underlying cause. Have you eaten raw, cold, leftover, or unclean food? Have you drunk unboiled water or been exposed to cold temperatures?"

"Today, several of you all drank spring water and fell ill together. This is the most direct epidemiological cause, so we should prioritize identifying gastrointestinal issues."

"Secondly, look at the symptoms. The core of acute gastroenteritis is four: paroxysmal abdominal pain, abdominal distension, nausea and vomiting, and diarrhea. It is often accompanied by mild low-grade fever, general weakness and chills."

"The most important point is the location of the pain. The pain of common gastroenteritis is basically concentrated in the epigastric region and around the navel. It is a dull ache, cramping pain, or shooting pain. The location of the pain is not fixed. Pressing on it will provide slight relief, or it may just be tenderness. It is not excruciating pain."

At this point, Chen Ping emphasized his point, teaching them to distinguish between easily confused serious illnesses.

"I will teach you how to differentiate between them to avoid misdiagnosis or missed diagnosis, and treating serious illnesses as minor ones, which is a major taboo in medical practice."

"If it's appendicitis, the pain might initially be in the upper abdomen, but after a few hours it will definitely be localized to the lower right abdomen."

"It is extremely painful when pressed, and even more painful when released, which is rebound pain. Patients dare not straighten their backs or walk, and even walking on a bumpy path will cause them severe pain."

"If it's a gastrointestinal spasm, the pain is sudden and intense, but it doesn't last long. Applying heat or drinking warm water can provide quick relief."

"If you don't have a fever or diarrhea, the four of you just have simple convulsions, which is not a big problem."

"If it is cholecystitis or gallstones, the pain is in the upper right abdomen, accompanied by nausea, vomiting, and a bitter taste in the mouth, which will be aggravated by eating greasy food."

"If it's peritonitis or intestinal perforation, the abdomen will be board-like, as hard as a rock, and it will be extremely painful to the touch. The patient will not allow you to press on it, and will also have a high fever and shock. It is an acute and severe case and must be transferred immediately."

"There are also urinary tract stones, which cause colicky pain in the lower back and abdomen, radiating to the lower back and groin. They are often accompanied by frequent urination, urgency, and hematuria, and are unrelated to diet."

Chen Ping explained things in great detail, even more so than the teacher would in class.

The group suddenly understood. The disease differentiation they had memorized from books, which had been so difficult to understand, became crystal clear when combined with real-life cases.

Xia Yutong immediately raised her hand and asked, "Dr. Chen, so in the future, when we encounter patients with stomach aches, we can first ask about the cause, check the location, feel the abdomen, and see if there is a fever or diarrhea, and then we can basically make a diagnosis, right?"

"Yes." Chen Ping nodded.

"Without equipment assistance, we rely on 'asking questions, looking, and touching'."

"Ask about diet, exposure to cold, bowel movements, and past medical history."

"Secondly observe their complexion, body temperature, and mental state."

"Three-handed palpation to differentiate between tenderness, rebound tenderness, and muscle tension."

"For common acute gastroenteritis, the symptoms include pain around the navel, a history of consuming raw or cold foods, low-grade fever and diarrhea, no rebound tenderness, and relatively good mental state. This is basically a 100% accurate diagnosis."

"This mild case can be treated with traditional Chinese medicine's methods of warming the middle jiao and dispelling cold, harmonizing the stomach and relieving pain, and with Western medicine's methods of replenishing fluids and relieving spasms."

Liu Zixuan listened intently and couldn't help but sigh, "Dr. Chen, textbooks never teach this much detail. School only makes us memorize definitions; we have no idea how to actually differentiate between diseases."

Zhang Lei also chimed in, "I really learned something valuable today; it's more effective than a month of classes in a classroom."

Chen Ping smiled and said, "That's why we need you to do internships. There's a big difference between what we medical students learn in school and what we do in practice in hospitals."

"What we need more in this line of work is practical experience, rather than theoretical knowledge from books."

"Now I'll remind you one more time, and you must remember it."

"The mountain streams and springs look clear and transparent, without any mud or turbidity, but the E. coli, parasite eggs, and microorganisms inside are completely invisible to the naked eye."

"City dwellers drink tap water and purified water for a long time, so their gut flora is delicate and cannot withstand the stimulation of raw water."

"No matter where you do your internship or work in the future, if you see any so-called spring water or pure natural water, do not drink or touch it, and do not let patients drink it blindly. Just because it looks clean does not mean it is harmless."

"Medical students should prioritize their own safety before saving others. If you don't even know how to mitigate risks yourself, how can you help your patients?"

The five people lowered their heads in shame. They were medical students, yet they didn't even know basic common sense.

Seeing that all five people were alright, Chen Ping stood up and said, "Alright, you can all go back to your dorms and rest."

"Yutong, keep an eye on Li Mengmeng tonight. If she still has a fever, call me."

"Okay, Dr. Chen." Xia Yutong nodded.

The five people returned to their dormitories. Chen Ping also returned to his own dormitory, lay on his bed, and glanced at the time. It was already past eleven o'clock.

"sleep……"

Chen Ping took off his clothes, covered himself with the blanket, and fell fast asleep.
