Blood group B means the person

  1. Can form antibody for B

  2. Cannot form antibody for B

  3. Can receive blood of AB group

  4. Cannot receive blood group O.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Individuals with blood group B have B antigens on their red blood cells; therefore, they do not produce anti-B antibodies, as doing so would cause their own blood to agglutinate.

Problem related to Rh factor arias when $Rh^+$ and $Rh^-$ bloods mix up

  1. In test tube

  2. Through transfusion

  3. Through pregnancy

  4. Both A and C.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Rh incompatibility causes clinical problems primarily through two routes: blood transfusion (Rh- recipient receives Rh+ blood) and pregnancy (Rh- mother carrying Rh+ fetus). Of the options given, transfusion is directly stated as correct. While pregnancy also causes Rh problems, the question specifically asks about 'bloods mix up', which most directly refers to transfusion.

In which of the following situations, there is risk of erythroblastosis foetalis

  1. Mother $Rh^+$, father $Rh^+$
  2. Mother $Rh^-$, father $Rh^-$
  3. Mother $Rh^-$, father $Rh^+$
  4. Mother $Rh^+$, father $Rh^-$.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Erythroblastosis foetalis occurs when an Rh-negative mother carries an Rh-positive fetus, leading to maternal antibody production against fetal red blood cells.

Blood corpuscles containing both A and B antigens are mixed with another blood serum. The blood corpuscles agglutinated. Blood serum belongs to blood group

  1. A

  2. B

  3. AB

  4. O.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

If blood corpuscles with both A and B antigens (AB group) are agglutinated by a serum, that serum must contain both anti-A and anti-B antibodies, which is characteristic of blood group O.

For safe blood transfusion

  1. Donor's RBC should not contain antibodies against recipient's serum

  2. Recipient's serum should not contain antigens against donor's antibodies

  3. Recipient's serum should not contain antibodies against RBC of donors

  4. Recipient's RBC should not contain antibodies against donor's antigens.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

For a safe transfusion, the recipient's plasma must not contain antibodies that react with the antigens present on the donor's red blood cells.

A mismatch during transfusion of blood causes

  1. Agglutination

  2. Erythroblastosis

  3. Haemopoies

  4. None of the above.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A mismatch in blood transfusion leads to the binding of antibodies to antigens on the donor's red blood cells, causing them to clump together, a process known as agglutination.

Assertion. Blood group 'O' has both anti-A and anti-B antibodies
Reason. It does not have any antigen

  1. A

  2. B

  3. C

  4. D.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Blood group O lacks both A and B antigens on its red blood cells, which is why it contains both anti-A and anti-B antibodies in the plasma. Both the assertion and reason are correct and the reason explains the assertion.
