Biology Form 4 Quiz: Blood Groups & Circulatory

Which of the following blood groups has Anti-B antibodies in plasma?

• A

• B

• AB

• O

Which blood group combination will cause agglutination?

• Donor O → Recipient A

• Donor A → Recipient AB

• Donor B → Recipient A

• Donor AB → Recipient AB

A patient’s red blood cells agglutinate with Anti-A and Anti-Rh serum. The blood group is:

• A–

• A+

• AB–

• AB+

A person with AB+ blood group can receive blood from:

• AB+ only

• A+, B+, AB+, O+

• Any blood group

• O– only

Which is TRUE about O– blood group?

• Universal recipient

• Universal donor

• Contains both A and B antigens

• Contains no antibodies

Which antigen determines the Rhesus factor?

• Antigen A

• Antigen B

• Antigen Rh (D)

• Antigen O

Agglutination occurs when:

• Antibodies react with matching antigens

• Antigens dissolve in plasma

• Platelets fail to clot blood

• Plasma proteins attack red blood cells

Which of the following situations is SAFE?

• Donor A → Recipient B

• Donor O– → Recipient AB+

• Donor AB → Recipient O

• Donor B → Recipient A

If a Rh– mother carries a Rh+ baby, the danger to the second baby is:

• Leukaemia

• Anaemia

• Haemolytic disease of the newborn

• Hypertension

A patient’s red blood cells agglutinate with Anti-B serum only. The blood group is:

• A

• B

• AB

• O
