The main reason why a Individual with type AB, Rh-negative blood cannot donate blood to an individual with type A, Rh-positive blood
anti-B antibodies in the recipient will agglutinate RBCs of the donor
anti-D antibodies in the donor will agglutinate RBC of the recipient
anti-A antibodies in the donor will agglutinate RBCs of the recipient
anti-B antibodies in the donor will agglutinate RBCs of the recipient
The Correct Answer is A
A. anti-B antibodies in the recipient will agglutinate RBCs of the donor: A recipient with type A blood has anti-B antibodies in their plasma; those antibodies will react with the donor’s B antigens on AB RBCs causing agglutination/hemolysis.
B. anti-D antibodies in the donor will agglutinate RBC of the recipient: The donor is Rh-negative and therefore does not have D antigen or anti-D on their RBCs; donor plasma rarely contains anti-D in this context and donor RBCs cannot agglutinate recipient RBCs.
C. anti-A antibodies in the donor will agglutinate RBCs of the recipient: An AB donor does not have anti-A (or anti-B) antibodies in their plasma; moreover transfused RBCs (not donor plasma) are the main concern.
D. anti-B antibodies in the donor will agglutinate RBCs of the recipient: An AB donor has no anti-B antibodies; even if present, donor anti-B would act on recipient B antigens (which A recipient lacks), so this statement is wrong.

Correct Answer is {"dropdown-group-1":"C"}
Explanation
A. Basophils: Basophils are involved in allergic and inflammatory responses (release histamine/heparin) and typically do not increase markedly in typical bacterial infections.
B. Monocytes: Monocytes can increase in chronic or certain infections and differentiate into macrophages, but they are not the first-line increase seen in acute bacterial infections.
C. Neutrophils: Neutrophils are the primary responders to acute bacterial infections and typically increase (neutrophilia) during bacterial invasion.
D. Eosinophils: Eosinophils increase mainly with parasitic infections and allergic reactions, not typically with bacterial infections.
E. Erythrocytes: Erythrocyte (RBC) counts do not typically increase in response to acute bacterial infection; if anything, severe/chronic disease may lower RBC counts.
Correct Answer is E
Explanation
A. Growth hormone (GH): GH is secreted by the anterior pituitary (somatotrophs).
B. Corticotropic hormone (ACTH): ACTH is secreted by the anterior pituitary (corticotrophs).
C. Prolactin (PRL): PRL is secreted by the anterior pituitary (lactotrophs).
D. Thyroid hormone (TH): TH (T3/T4) is secreted by the thyroid gland, not the pituitary.
E. Oxytocin (OT): The posterior pituitary (neurohypophysis) releases oxytocin and ADH (though both are synthesized in the hypothalamus).
