I . First step

Step 1 : Leave the position with the rattlesnake. If the snake feels threatened, it can bite again. Therefore, the snake-bitten person should stay away from the snake's attack range. Stay away from snakes at least 6 meters.

Step 2 : Receiving medical assistance. Finding the fastest possible medical assistance is very important. Most hospitals have snake venom-resistant serum, and most treatment efforts before going to the hospital do not help much. If you are in an area where you can call 115, it is your best option. If not, seek help to get to the nearest hospital for you or someone with the snake bite.
Even if you're not sure if you're bitten by a rattlesnake, you still need to go to the hospital right away. It would be better if you were in the hospital when symptoms of venom infiltration began to appear.

Step 3 : DO NOT lift the area bitten by the snake above the heart. If you raise the area above the heart, the blood containing the venom from the bite will move to the heart faster.

Step 4 : Keep your body motionless. If possible, avoid moving until you receive support. Moving will increase the speed of blood circulation, causing venom to spread in the body faster. Therefore, you or someone with a snake bite should avoid moving if possible.
Of course, if you are alone, seek help that is more important than keeping your body immobile.

II . Handle the bite

Step 1 : Remove clothing and jewelry. Snake skin can swell quickly, so cut or remove clothes near the bite. At the same time, remove all jewelry in this area. If you do not remove it before the bite is swollen, the objects may clog the blood vessels, and the jewelry must be removed.

Step 2 : Leave the wound to bleed. Let the bite bleed freely for about thirty seconds. This process will help some venom flow out of the wound.

Step 3 : Use suction pump device. It is better to try to suck the venom out, but only if you have a special tool. The suction device often comes with instructions for use, but basically you put the straw on the bite to suck the venom out.

Step 4 : Put a clean bandage over the wound. Do not remove wound wash water, as it can wash snake venom on your skin. Health professionals can use traces on your skin to support the treatment process, by determining which bite you are bitten by.

Step 5 : Brace or bandage. A brace or bandage will help keep the wound inactive, limiting blood circulation at the bite. Since then, the venom has not spread.
To make a bandage for the arm, create a triangle from the fabric by folding or cutting the cloth. Roll a triangle tape around your arm, place your elbow in the middle. Your hand or a snake-bitten person should fold at the elbow to fit the bandage. Tie the ends of the tape around your shoulders. Place your hand outwards to create a fulcrum for the triangle.
Find items to support your hands, such as sticks, newspaper rolls, or even cloth rolls. Place the brace on the arm length, try to connect the joint at the top and bottom of the wound. Tie the brace to the arm with anything you have, from the waist to the tape or the cloth. Do not tie the injured area but tied to its edges. If the wound is too swollen, you need to reduce the pressure on the brace.

III . Chờ đợi Trợ giúp

Step 1
Comforting injured people. Talk to her. Ask her questions to stop paying attention to the bite. Anxiety and panic can increase heart rate and make venom easily spread.
If you are a snake bite, try to stay calm. Breathe slowly and deeply to calm down.
You can also call the Anti-Poison Center while you wait

Step 2

Observe swelling and discoloration. The easiest way to identify venomous snakebites is to observe swelling at the bite site. Bites can also change color.
Another manifestation of venomous snakebites is that there is only one or two stain marks instead of a stain, meaning that the teeth are smaller.
In addition, dizziness, pain in the bitten area, blurred vision and stinging sensations in other areas of the body are signs of being bitten by venomous snakes, along with excessive sweating.
Step 3
Check for signs of shock. A symptom is a lost person. Other symptoms include heart palpitations, shortness of breath, nausea and dizziness. At the same time, the pupil of the bitten person will also expand.
If a person begins to enter a shocking period, place the person on his or her back and raise his or her feet to at least 30 cm. At the same time, help them keep their body warm.
Conduct cardiopulmonary resuscitation if the person bitten by the snake does not have signs of life such as breathing, coughing or movement.
Step 4
Use alcohol or caffeine. These substances can make your body absorb the venom faster. Therefore, do not use these drinks after being bitten by rattlesnakes.

IV . Knowing Things to Avoid

Step 1
Do not slit the wound. The popular view is that slitting the wound can help release venom. However, tests prove that this method has no effect and you can become infected if using a dirty knife.
Step 2
Do not use your mouth to suck the wound. When sucking wounds with your mouth, you transfer venom into your mouth. In addition, your mouth is a bacterium, so you can infect the bite with bacteria from your mouth.
In fact, within 15 minutes, the venom has entered the lymphatic system, so it is pointless to smoke venom after this point.
Step 3
Do not use the syrup. The syrup prevents blood from circulating to your hands. This advice was given in the past, given that it will help prevent venom from spreading to the whole body. However, this is often more harmful than beneficial.
Step 4
Do not apply ice or immerse the wound in water. It is very important to maintain undamaged tissues for as long as possible. Using ice or water does not support this because it reduces blood circulation.
Step 5
Do not urinate on the bite. This idea is as silly as its name, a myth that peeing on a bite will help neutralize toxins. Urine does not help the bite and you should take the time to go to the hospital rather than doing it.
Step 6
Do not give any snake-bitten person anything to eat or drink while waiting for care. Including medicine and alcohol. You need to keep your metabolic rate slow.

The first time I attended a first aid course so far when I was a first aidist for 2 years, I remember the first time I was taught useful things from the teachers. The first thing I should do in any case that requires first aid is to follow 3C rules: Look and check first, Call, Care. If in the process of helping we make the victim hurt or have symptoms worse, don't continue because we can make the victim worse. Then, do a general survey, including checking and determining if the victim is in the case of unconsciousness, breathing, and the pulse is still beating. The teacher instructed us to be extremely careful in trying to stay calm and focused, they told me to always carry rescue equipment, wear gloves when working, when going to first aid it is important to protect yourself The self, and most importantly, to administer first aid is to learn as much as possible about what happened to the victim, see their alertness. In the next steps, we must call an ambulance quickly. Bringing them into a recovery position will prevent them from choking if they vomit while you call an ambulance. And so far I have helped many people, I am very happy !

( lần đầu tiên tôi được học một khóa học sơ cứu cho đến nay khi tôi là sơ cứu viên đã 2 năm rồi, tôi nhớ lần đầu tiên tôi được dạy những điều bổ ích từ các thầy cô . Điều đầu tiên tôi nên làm trong bất cứ trường hợp nào mà cần đến sơ cứu đó là tuân theo quy tắc 3C: Coi và kiểm tra sơ, Cuộc gọi, Chăm sóc. Nếu trong quá trình giúp đỡ mà chúng ta làm cho nạn nhân đau hay có những triệu chứng tồi tệ hơn, thì đừng tiếp tục vì chúng ta có thể làm nạn nhân tồi tệ hơn. Sau đó, làm một cuộc khảo sát chung, bao gồm việc kiểm tra và xác định xem nạn nhân có đang trong trường hợp bất tỉnh hay không, đang thở, và mạch vẫn đập. Giáo viên dặn dò chúng tôi vô cùng cẩn thận trong việc cố gắng bình tĩnh và tập trung , họ bảo tôi phải luôn mang theo thiết bị cứu hộ, đeo găng tay khi làm việc, khi đi sơ cứu quan trọng là phải tự bảo vệ bản thân, và quan trọng nhất để tiến hành sơ cứu là tìm hiểu càng nhiều càng tốt về những gì đã xảy ra với nạn nhân, xem độ tỉnh táo của họ. Trong những bước tiếp theo, chúng ta phải gọi xe cứu thương nhanh chóng. Đưa họ vào tư thế phục hồi sẽ giúp họ không bị nghẹt thở nếu họ có ói trong lúc bạn gọi xe cứu thương. Và đến nay tôi đã sơ cứu được rất nhiều người , tôi thấy rất vui ! )

Tui khá kém tiếng anh nhưng đây là những gì mà tui có thể giúp bạn, mong là nó giúp dc bạn, có khả năng 50% nó sai về từ ngữ đấy ^^

Chọn đáp án B

Joe has finished his first-aid course. He proves extremely helpful as a rescue worker: Joe đã hoàn thành khóa học sơ cứu. Anh ấy tỏ ra vô cùng hữu ích trong công việc của nhân viên cứu hộ

A. Although Joe proves extremely helpful as a rescue worker, he hasn’t finished his first-aid course: Mặc dù Joe tỏ ra vô cùng hữu ích trong công việc của nhân viên cứu hộ, anh ấy vẫn chưa hoàn thành khóa học sơ cứu của mình

B. Having finished his first-aid course, Joe proves extremely helpful as a rescue worker: Hoàn thành xong khóa học sơ cứu, Joe tỏ ra vô cùng hữu ích trong công việc của nhân viên cứu hộ

C. Without finishing his first-aid course, Joe proves extremely helpful as a rescue worker: Không cần hoàn thành khóa học sơ cứu, Joe tỏ ra vô cùng hữu ích trong công việc của nhân viên cứu hộ

D. However helpful Joe proves as a rescue worker, he has’t finished his first-aid course: Dù Joe có tỏ ra hữu ích trong công việc của nhân viên cứu hộ như thế nào đi nữa, (thực tế là) anh ấy đã không hoàn thành khóa học sơ cứu.

Ta thấy ý của câu gốc là sau khi hoàn thành khóa học sơ cứu thì Joe tỏ ra vô cùng hữu ích trong công việc của nhân viên cứu hộ, vậy nên phương án B là phù hợp nhất.

Ta có: Having finished his first-aid course, Joe proves extremely helpful as a rescur worker = Joe, who has finished his first-aid course, proves extremely helpful as a rescue worker.
