Answer to Question 1

B
Feedback:
Hematopoietic cytokines are diverse substances produced mainly by bone marrow and white blood cells (WBCs). They regulate many cellular activities by acting as chemical messengers among cells and as growth factors for blood cells. Blood cells are not made up of cytokines, and they do not perform phagocytosis. The presence of antigens, not antibodies, can prompt the expression of certain cytokines.

Answer to Question 2

C, D
Feedback:
Health care providers use the combination drug Cortisporin Otic (neomycinpolymyxin Bhydrocortisone) for the treatment of acute external otitis media. Neomycin and polymyxin B are antibiotics, which combat bacterial infections. Hydrocortisone is a steroid, which reduces the actions of chemicals in the body that cause inflammation, redness, and swelling. This medication does not contain analgesics, anesthetics, or immunomodulators.
