Use the answer bank below. Answers can be used more than once.                                         Imagine yourself working in the Emergency Department at UCSD hospital in Hillcrest. You have a gunshot wound patient who has lost a lot of blood. When he arrives his blood pressure is: 80/40 mmHg (this is low). While the tests are being done to figure out his blood type what can you do to correct the blood pressure problem? (30). The blood test results come back and you find out his blood type is A+. The antigen/s on his red blood cells is/are: (31: enter them all no commas or periods or spaces, using the table below); The antibody/ies in his blood is/are: (32: enter them all no commas or periods or spaces, use the table below). What are 2 blood types that he can safely receive: (33: enter them both no commas or periods or spaces, use the table below)? What is 1 blood type he cannot safely receive: (34, use the table below)? What would happen if you gave him this unsafe blood type: (35)? A. Give him an isosmotic solution F. Rh antigens K. Type A- P. Type O+ U. The antibodies from the donated blood would stick to the antibodies in his blood B. Give him a hyperosmotic solution G. Anti A L. Type B+ Q. Type O- V. The antibodies on his red blood cells would stick to the antigens on the donated red blood cells C. Give him a hyposmotic solution H. Anti B M. Type B- R. The antibodies in his blood would stick to the antigens on the donated red blood cells   D. A antigens I. Anti Rh N. Type AB+ S. The antibodies from the donated blood would stick to the antigens on his red blood cells   E. B antigens J. Type A+ O. Type AB- T.
