Ans: A
Feedback: In patients undergoing a total knee replacement, narcotics and anti-infectives are
often administered. However, in a patient with paroxysmal nocturnal hemoglobinuria, anticoagulants are the primary medication to be administered. PNH is characterized by intravascular hemolysis, cytopenia, frequent infections, bone marrow hyperplasia, and a high incidence of life-threatening venous thrombosis.
