People have been donating blood since the early twentieth century to help accident victims and patients undergoing surgical procedures. Usually a pint of whole blood is donated, and it is then divided into platelets, white blood cells, and red blood cells. People can donate blood (for red blood cells] about once every two months. Transfusing the blood from the donor to the recipient is straightforward. It involves taking the blood from a donor's arm vein by means of a hypodermic syringe. The blood flows through a plastic tube to a collection bag or bottle that contains sodium citrate, which prevents the blood from clotting. When the blood is given to a patient, a plastic tube and hypodermic needle are connected to the recipient's arm. The blood flows down from the container by gravity. This is a slow process and may last as long as 2 hours to complete the infusion of blood into the recipient. The patient is protected from being infected during the transfusion. Only sterile containers, tubing, and needles are used, and this helps ensure that transfused or stored blood is not exposed to disease causing bacteria. Negative reactions to transfusions are not unusual. The recipient may suffer an allergic reaction or be sensitive to donor leukocytes. Some may suffer from an undetected red cell incompatibility. Unexplained reactions are also fairly common, Although they are rare, other causes of such negative reactions include contaminated blood, air bubbles in the blood, overloading of the circulatory system through administration of excess blood, or sensitivity to donor plasma or platelets. Today, hospitals and blood banks go to great lengths to screen all blood donors and their blood. All donated blood is routinely and rigorously tested for diseases, such as HIV, hepatitis B, and syphilis. When the recipient is a newborn or an infant, the blood is usually irradiated to eliminate harmful elements. Donated blood is washed, and the white blood cells and platelets removed. Storing the blood sometimes requires a freezing process. To freeze the red blood cells, a glycerol solution is added. To unfreeze, the glycerolis removed. The ability to store blood for long periods has been a boon to human health.

According to the passage, how often can people donate blood for red blood cells?

A. Every four months

B. Every three month

C. Every two months

Tác giả có ý gì trong đoạn văn?

A. Hiến máu có lợi cho nhân loại.

B. Không thể ngăn ngừa đông máu.

C. Làm đông máu sẽ phá hủy tiểu cầu.

D. Truyền máu là một quá trình nguy hiểm.

Thông tin: The ability to store blood for long periods has been a boon to human health. (Khả năng lưu trữ máu trong thời gian dài là một lợi ích cho sức khỏe con người.)

Mọi người đã hiến máu từ đầu thế kỷ XX để giúp người bị tai nạn và bệnh nhân trải qua các thủ tục phẫu thuật. Thông thường, một lượng máu được hiến tặng, sau đó chia thành tiểu cầu, bạch cầu và hồng cầu. Mọi người có thể hiến máu (đối với hồng cầu) khoảng hai tháng một lần. Truyền máu từ người hiến tặng cho người nhận là điều đơn giản. Nó bao gồm lấy máu từ tĩnh mạch cánh tay của người hiến tặng bằng ống tiêm dưới da. Máu chảy qua ống nhựa vào túi hoặc chai chứa natri citrat, giúp ngăn máu đông. Khi máu được truyền cho bệnh nhân, một ống nhựa và kim dưới da được nối với cánh tay của người nhận. Máu chảy xuống từ bình chứa bằng trọng lực. Đây là một quá trình chậm và có thể kéo dài đến 2 giờ để hoàn thành truyền máu vào cho người nhận. Bệnh nhân được bảo vệ khỏi bị nhiễm bệnh trong quá trình truyền máu. Chỉ sử dụng các bình chứa, ống và kim vô trùng, điều này giúp đảm bảo rằng máu truyền hoặc lưu trữ không bị nhiễm vi khuẩn gây bệnh. Phản ứng phụ của việc truyền máu không phải là bất thường. Người nhận có thể bị dị ứng hoặc nhạy cảm với bạch cầu. Một số có thể bị ảnh hưởng bởi sự không tương thích của các tế bào hồng cầu không bị phát hiện. Các phản ứng không giải thích được cũng khá phổ biến. Mặc dù hiếm gặp, các nguyên nhân khác của phản ứng phụ như máu bị nhiễm trùng, bong bóng không khí trong máu, quá tải hệ thống tuần hoàn thông qua việc dùng quá mức máu, hoặc nhạy cảm với huyết tương hoặc tiểu cầu. Ngày nay, các bệnh viện và ngân hàng máu theo dõi nghiêm ngặt những người hiến máu và máu của họ. Tất cả máu hiến tặng đều được kiểm tra nghiêm ngặt và nghiêm túc để kiểm tra các bệnh như HIV, viêm gan B và giang mai. Khi người nhận là trẻ sơ sinh hoặc trẻ nhỏ, máu thường được chiếu xạ để loại bỏ các yếu tố gây hại. Máu đã được hiến được làm sạch, và lấy ra bạch cầu và tiểu cầu. Lưu trữ máu đôi khi đòi hỏi quá trình đông lạnh. Để làm đông các hồng cầu, một dung dịch glycerol được thêm vào. Để giải đông, glycerolis được loại bỏ. Khả năng lưu trữ máu trong thời gian dài là một lợi ích cho sức khỏe con người.
