Answer 2

Explanation:

Transfusions are given to increase the blood's ability to carry oxygen, restore the amount of blood in the body (blood volume), and correct clotting problems. Transfusions are usually safe, but sometimes people have adverse reactions.

To minimize the chance of an adverse reaction during a transfusion, health care practitioners take several precautions. Before starting the transfusion, usually a few hours or even a few days beforehand, the person is cross-matched with the donor blood (not done for transfusions of plasma or platelets).

After double-checking labels on the bags of blood that are about to be given to ensure the units are intended for that recipient, the health care practitioner gives the blood to the recipient slowly, generally over 1 to 4 hours for each unit of blood. Because most adverse reactions occur during the first 15 minutes of the transfusion, the recipient is closely observed at first. After that, a nurse checks on the recipient periodically and must stop the transfusion if an adverse reaction occurs.

Most transfusions are safe and successful. However, mild reactions occur occasionally, and, rarely, severe and even fatal reactions may occur.

The most common reactions, which occur in 1 to 2% of transfusions, are

Fever

Allergic reactions
