Answer 30

30.  Choice A is the correct answer.  Hemophilia A is factor VIII deficiency.  Hemophilia B is a deficiency of factor IX.

Question 30

30.  Hemophilia A is a deficiency of what factor?

A.  Factor VIII

B.  Factor IX

C.  Factor V

D.  Protein S

Answer 29

29.  Choice C is the correct answer.  With Factor XI deficiency you get a prolonged PTT and a normal PT.  Factor XI is part of the intrinsic pathway and therefore will prolong the PTT.

Question 29

29.  Which of the following is consistent with a Factor XI deficiency:

A.  Prolonged PTT and a prolonged PT
B.  Normal PTT and prolonged PT
C.  Prolonged PTT and normal PT
D.  Prolonged PTT and prolonged PT

Answer 28

28.  Choice A is the correct answer.  With hemolytic anemia, the reticulocyte count is high.  There is a shortened RBC survival less than 100 days.  There are intrinsic and extrinsic causes of hemolytic anemia.  RBC abnormalities include spherocytes, helmet cells, acanthocytes, blister or bite cells, red cell ghosts and prominent basophilic stippling.

Question 28

28.  All of the following is true regarding hemolytic anemia except:

A.  Reticulocyte count is low
B.  There is a shortening of the RBC survival to less than 100 days
C.  RBC abnormalities include spherocytes, helmet cells, acanthocytes, blister or bite cells, Red Cell ghosts, and prominent basophilic stippling
D.  There are intrinsic and extrinsic causes of hemolytic anemia

Answer 27

27.  Choice B is the correct answer.  Chloramphenicol has been implicated in aplastic anemia.  Other medications that have been implicated in aplastic anemia include:  NSAIDS, tegretol, dilantin, depakote, and nifedipine.  

Question 27

27.  Which of the following medications have been implicated in aplastic anemia?

A.  Keppra
B.  Chloramphenicol
C.  Tylenol
D.  Amoxicillin

Answer 26

26.  Choice A is the correct answer.  Isolated anemia is not consistent with aplastic anemia.  Aplastic Anemia usually presents with pancytopenia, low reticulocyte count, and bone marrow hypoplasia.

Question 26

26.  Which of the following is not constant with Aplastic Anemia?

A.  Isolated Anemia
B.  Pancytopenia
C.  Low Reticulocyte Count
D.  Bone Marrow Hypoplasia
