Chapter 15, Problem 1Q

Summary Introduction

Introduction:

Based on the presence of the antigen, the blood type is divided into four types A, B, AB, and O. The presence of the Rh (Rhesus) antigen is depicted by a + (positive sign) or D+. In the given list of the blood group, all the blood types have a Rh antigen.

Answer to Problem 1Q

Correct answer:

The correct answer is option (a) ABRhD+.

Explanation of Solution

Explanation/justification for the correct answer:

Option (a) ABRhD+. The blood group AB has both the antigen on the RBCs and no antibodies in the blood, also, the presence of the Rh group does not react with the antigen lacking Rh. So, this blood group has no immunological response towards transfusion of any blood and this property make it a universal recipient.

Explanation for the incorrect answer:

Option (b) ABRhD-. The absence of the Rh factor makes this blood group a non-universal recipient, as if the transfusion of the RhD+ blood in done than the body will recognize Rh+ as a foreign antigen and elicit an immune response. Hence, this is an incorrect answer.

Option (c) ORhD+. The O blood type have both type of antibodies, that is anti-A and anti-B in their plasma. So, the blood having A or B antigen may elicit an immune response. So, this is an incorrect answer.

Option (d) ORhD-. The O blood type have both type of antibodies, that is anti-A and anti-B in their plasma. So, the blood having A or B antigen may elicit an immune response. The absence of the Rh factor can also elicit the response against RhD+ blood. Hence, it is an incorrect option.

Option (e) ARhD+. The A blood type have anti-B in their plasma. So, the blood having B antigen may elicit an immune response. Hence, it is an incorrect answer.

Conclusion

The ABRhD+ individual is a universal recipient.
