If someone is bitten by a snake, you won’t know if it’s a dry bite or a venomous bite – so to be safe, always treat any bite as a venomous bite.

Dry bites, whereby no venom is released, are painful and cause localised redness and swelling.

If the bite is venomous, other symptoms may include a stinging or burning sensation on the skin and feelings of nausea, dizziness, anxiousness and confusion. In severe cases, the bite may result in paralysis or coma.

Only a handful of people die from a venomous snake bite in Australia each year. Knowing what to do if bitten by a snake and giving proper first aid is essential in keeping those numbers down and reducing them even further.

Snake venom is carried in the lymphatic system and not in the blood stream, as many mistakenly believe. That’s why the main aim of snake bite first aid is to reduce lymphatic flow by applying continuous firm pressure over the affected limb. This is known as the Pressure Immobilisation Technique (PIT).

Immediate first aid should be applied to any snake bite victim. Follow the steps below and don’t forget to read the DON’Ts printed in red at the bottom of our guide.

Vào ngày đầu tiên của cấp hai, tớ tình cờ gặp một bạn nữ, người bạn thân nhất của mình bây giờ. Lúc đầu, tớ nghĩ rằng cô ấy rất nghiêm túc và ít nói. Tuy nhiên, sau thời gian gần gũi với bạn ấy hơn, bạn ấy hóa ra rất vui tính và hay nói.

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.

First aid is the assistance given to any person suffering a sudden illness or injury,with care provided to preserve life, prevent the condition from worsening, or to promote recovery. It includes initial intervention in a serious condition prior to professional medical help being available, such as performing CPR while awaiting an ambulance, as well as the complete treatment of minor conditions, such as applying a plaster to a cut. First aid is generally performed by the layperson, with many people trained in providing basic levels of first aid, and others willing to do so from acquired knowledge. Mental health first aid is an extension of the concept of first aid to cover mental health.

There are many situations which may require first aid, and many countries have legislation, regulation, or guidance which specifies a minimum level of first aid provision in certain circumstances. This can include specific training or equipment to be available in the workplace (such as an Automated External Defibrillator), the provision of specialist first aid cover at public gatherings, or mandatory first aid training within schools. First aid, however, does not necessarily require any particular equipment or prior knowledge, and can involve improvisation with materials available at the time, often by untrained persons.

First aid can be performed on all mammals, although this article relates to the care of human patients.
