Zhou Sheng picked up the mercury sphygmomanometer.
Check to see if the mercury column is at the "0" point.
This is similar to our mercury thermometer. Before measurement, the mercury must be at the correct scale point. Otherwise, the read data will be inaccurate.
After confirming that the position of the mercury column is correct.
Zhou Sheng asked Cao Xin to put his arms flat on the table so that his elbows were at the same level as his heart.
This is the standard posture for using a mercury sphygmomanometer.
Keep the mercury meter, elbows, and heart at the same level.
The next step is to wrap the air sleeve evenly and tightly against the skin on the upper arm. It should not be tied too tightly or too loosely.
Of course, the position of the binding is also particular.
Visual inspection shows that the lower edge of the air sleeve is about 2~3cm above the cubital fossa.
The air cuff is on the surface of the brachial artery.
After it is tied, place the stethoscope head on the brachial artery.
One thing to note is that the earpiece cannot be stuffed into the air sleeve.
It should be on the brachial artery at the lower edge of the air sleeve.
This is certainly true for veteran Zhou Sheng.
At this point, the preliminary actions are completed.
Enter the actual measurement process.
Zhou Sheng tightened the air valve on the air cuff and quickly inflated the air cuff while auscultating.
When the brachial artery pulsation disappears and the mercury column rises by another 20 to 30 mmhg.
Monday, unscrew the air valve and release the air.
At this time the mercury slowly dropped.
When he heard the first pulse of the brachial artery again, Zhou Yisheng quickly read the value on the mercury column at that moment.
120mmhg.
This value is systolic blood pressure, which is also what we usually call high pressure.
This was not over yet. Zhou Sheng continued to deflate and listened carefully to the stethoscope in his ear. When the pulse sound weakened, Zhou Sheng read the blood pressure scale again.
80mmhg.
Needless to say, this value is diastolic blood pressure, which is what we usually call low pressure.
Here, the test ends.
Zhou Sheng reported the measurement results to the examiner, "Systolic blood pressure 120mmhg, diastolic blood pressure 80mmhg."
The examiner nodded.
Zhou Sheng's entire operation was flawless, and the measurement process was very smooth.
A perfect operation.
But it's not over yet.
According to the requirements of the exam, the examiner will also ask the candidates two questions.
The examiner asked: "Why can't the stethoscope head be inserted under the air sleeve?"
This question was answered by his father before he went to medical school.
He blurted out: "Putting the stethoscope in the cuff will make the cuff tighter and increase the pressure, causing errors. It will also reduce the pressure in the brachial artery, causing the measured blood pressure to be higher than the true value."
"Yeah." The examiner was very satisfied with Zhou Sheng's answer. He then asked: "What is the correct position of the brachial artery when measuring blood pressure?"
"Two positions, sitting and lying. The brachial artery is at the level of the fourth costal cartilage in the sitting position and the mid-axillary line in the lying position."
A problem of this magnitude.
For Mr. Zhou, who has been helping in the clinic since he was a child, this is simply a pediatric problem.
I've been playing with this thing since I was a kid.
The three examiners nodded simultaneously.
Score it, needless to say.
Not giving full marks to this question is unreasonable.
Then, comes the second question.
This question is about eye examination.
The examiner said to Mr. Zhou: "Do eye movement, eye accommodation and vergence reflex tests."
This is also a basic inspection item.
Of course, Zhou Sheng comes at his fingertips.
Both tests use your fingers.
The approach is slightly different.
First come on Monday for eye movement examination.
He stretched out an index finger and placed the fingertip half a meter in front of Cao Xin's eyes.
Then he said: "Don't move your head, just follow my fingertips with your eyes."
Cao Xin said "hmm".
After sitting here for a long time, he finally made his first sound.
Zhou Shengsheng's fingertips moved in six directions: left, upper left, lower left, right, upper right, and lower right, and wrote a capital "h" in the air.
Cao Xin's eyeballs followed Zhou Sheng's fingertip movements.
Eye movement testing is that simple.
Next, there is eye accommodation and convergence reflex examination.
This test is even simpler.
Zhou Sheng retreated a little, to a position of about one meter.
He also extended his index finger and said, "Look at my index finger."
Then he moved his fingers in front of Cao Xin's nose at a constant speed until he stopped at a position of about 10cm.
This test actually detects the constriction of the pupils on both sides of the two eyes and the convergence of the two eyes.
It's a lot like playing cross-eyed when I was a kid.
Both eye examinations were completed easily by Zhou Sheng.
Then came the question and answer session.
It was still the examiner in the middle who asked: "My eyes have poor convergence function, so why can't they focus and think?"
"Oculomotor nerve damage."
Problems with eye movements are definitely related to nerves.
It's very simple and can be answered in seconds by Zhou Sheng.
"What is the clinical significance of having unequal pupils on both sides and constriction on one side?"
This problem is even simpler.
As an expert in the field of supernatural beings, Zhou Zhou had come across many cases in which pupils had different sizes. In the end, he was diagnosed with a problem with the central nervous system in the head.
He has also encountered it in actual clinical practice.
He answered without hesitation.
"If the pupils are anisolarge, a central nervous system or iris innervation disorder may be considered."
Two questions about the eyes were answered fluently.
The three examiners exchanged looks.
From the moment this candidate came in, he was full of confidence and relieved the pressure of his peers.
He is an experienced veteran.
It seems that I got a lot of exercise during my internship in the hospital.
The three of them gave their first full score of 20 points today without any hesitation!
Today, in the previous rounds, they also gave high scores of 18 and 19.
But don't look at the 1 point difference.
That's because the full score for this item is only 20 points.
If you have enough time and take more tests, you will definitely be able to widen the 1-point gap to 2 points, 3 points, 4 points, 5 points... or even more.
The difference between 100 points and 99 points is not just a 1 point difference.
Zhou Sheng could not see the score on the spot.
But he had already seen it from the expressions of the three examiners.
My performance should be king-level.
Next, it’s Cao Xin’s turn.
And Zhou Yisheng has to cooperate with him.
Cao Xin’s clinical skills were quite good.
I also practiced at the Central Hospital for more than a year.
But this is my first time taking this kind of exam.
The examiner, who looked like three giant Buddhas, was right in front of him, and he couldn't let go.
So the performance is average.
The operation was so-so, and when answering questions, he stuttered even more.
Coupled with the perfect performance of Zhou Yisheng in front, the examiners had a comparison in mind.
So his score was not high, and he only got 12 points from two questions.
The two finished the first physical examination of this second stop.
We are about to enter the second item, basic clinical operations.
This item also has three examiners.
And what's even more terrifying is that this time I don't even have a companion.
Enter the exam one person at a time.
1v3 rhythm!
Zhou Sheng and Cao Xin had just met, and they had to separate immediately.
