The answer to this is A. A lot of people assume that measuring the client’s vital signs is the most important part about undergoing a blood transfusion. While this is necessary, this can wait until the crossmatching is done. The nurse should make sure that the person’s blood type is compatible with the blood of the donor.
There are so many complications that may occur when the wrong type of blood is transfused to the patient. A lot of these complications are life-threatening and can literally make the patient suffer. This explains why this should be avoided at all times and the right blood should be matched accordingly.
