The same day, another patient arrives at the ER also needing a blood transfusion. The patient has type 0- blood. What are all possible blood types this person can receive? Again, include concepts of blood typing and donor/recipient info to justify your answer. Finally, why are people with type 0- blood medically important?

Expert Solution

Answer

a) The only pssible blood type the patient with O- blood can receive is : O-

O- blood do not contain any antigens at all. There are no A, B antigens as well as no Rh antigens. It contains Anti-A, Anti-B and Anti-Rh antibodies.
All other blood types either have A or B antigens and Rh antigens.
Even O+ blood contains Rh antigens.

- If any other blood type is transfused to the patient with O- blood, the antibodies in the patient's plasma will detect the antigens in donor's blood as foreign antigens.
- The antibodies will attack newly transfused red blood cells.
- This will lead to agglutination reaction, clumping and destruction of red blood cells.

b) The people with type O- blood medically important because, they can donate blood to persons with all other blood types.

As O- blood do not have any antigens, there are no chances of agglutination reaction when combined to any other blood types.
Hence, O- blood is considered universal donor.

1.a patient has been injured and is in need of a blood transfusion. when she arrives at the ER, doctors determine that she has type A+ blood. what antigens are present on her erythrocytes? what antibodies are present in her blood? what blood type(s) can she receive in her blood transfusion? 2. If an agglutination reaction only occurs when an anti-B antibody is applied, then the blood type must be typed ___(A/B) ___(+/-)

A patient appears in the ER. He is hyperventilating and his blood pH is 7.6. It turns out he has taken an accidental overdose of aspirin. Aspirin is Acetylsalicylic acid. In the stomach it is hydrolyzed to acetic acid and salicylic acid. The salicylic acid acts on the central nervous system to increase respiration rates. a)What does hyperventilation do to the pH of the blood stream? b)Why? c)Patients suffering from an aspirin overdose are treated with activated charcoal to absorb...
