Question

A person with blood group ARh^– can receive the blood transfusion from which of the following types?
A. BRh^–
B. ABRh^– 
C. ORh^– 
D. ARh^– 
E. ARh⁺ 
Choose the correct answer from the options given below :

• A. D and E only
• B. D only
• C. A and B only
• D. C and D only

Answer 1

The Correct Option is D

To determine from which blood types a person with blood group ARh^– can receive a transfusion, we need to consider both the ABO and Rh compatibility. Here is a step-by-step explanation:

1. Understanding Blood Group Compatibility:
   • The ABO blood group system is determined by the presence or absence of antigens A and B on red blood cells.
   • The Rh system is determined by the presence (Rh⁺) or absence (Rh^–) of the Rh antigen.
2. Compatibility for ARh^– Blood Type:
   • A person with ARh^– blood type has A antigens and no Rh antigens.
   • Thus, they cannot receive blood with B or AB antigens because that would cause an immune reaction (they can only receive A or O type).
   • They can receive Rh^– blood, as Rh⁺ would lead to an immune response.
3. Evaluating the Options:
   • A. BRh^–: Has B antigens, so not compatible.
   • B. ABRh^–: Has both A and B antigens, so not compatible.
   • C. ORh^–: Universal donor type with no A or B antigens and is Rh^–, so it is compatible.
   • D. ARh^–: Same blood group, so fully compatible.
   • E. ARh⁺: Has Rh antigens, which makes it incompatible.
4. Conclusion: The compatible blood types for ARh^– are ORh^– and ARh^–. Therefore, the correct answer is C and D only.
