  • True
  • False

Question 3

Question
Which lab test shows the actual volume of RBCs in a unit of whole blood
Answer
  • Hct
  • Hgb
  • RBC count
  • MCV

Question 4

Question
Which lab test is useful in distinguishing between microcytosis anemia and hypochromia anemia?
Answer
  • MCV
  • MCH
  • Reticulocyte count
  • MCHC

Question 5

Question
When classifying anemia, first you look at the [blank_start]MCV[blank_end] test. If the result is high, then you have a [blank_start]macrocytic[blank_end] anemia and need to look at the [blank_start]Vitamin B12 and folate levels[blank_end] to determine if the anemia is [blank_start]Vitamin B12 deficiency[blank_end] or [blank_start]Folic acid deficiency[blank_end].
Answer
  • MCH
  • MCV
  • macrocytic
  • normocytic
  • microcytic
  • Reticulocyte count
  • Vitamin B12 and folate levels
  • Serum ferritin levels
  • Vitamin B12 deficiency
  • Anemia of Chronic Disease
  • Folic acid deficiency
  • Iron-deficiency anemia

Question 6

Question
Microcytic anemias are caused by impaired Hct synthesis.
Answer
  • True
  • False

Question
TIBC is decreased in iron deficiency.
Answer
  • True
  • False

Question 8

Question
Which lab test is the best indicator of iron deficiency or iron overload?
Answer
  • TIBC
  • Serum iron level
  • Ferritin
  • % Transferrin Saturation

Question 9

Question
Iron is best absorbed on an empty stomach.
Answer
  • True
  • False

Question 10

Question
Body does not store much vitamin B12 so it is easy and quick to become vitamin B12 deficient.
Answer
  • True
  • False

Question 11

Question

Answer
  • MCV
  • Vitamin B12
  • Reticulocyte count
  • Hct

Question 12

Question

Answer
  • 1 week
  • 2 months
  • 4 months
  • 1 year

Question 15

Question
Which of the following is a hemoglobin variant that causes manifestations of sickle cell disease when paired with HbS but does not when paired with itself?
Answer
  • HbA
  • HbC
  • HbS
  • HbF

Question 16

Question
At what age are people screened for sickle cell anemia
Answer
  • Before 18 years old
  • Before 4 years old
  • Before 2 years old
  • Before 2 months old

Question 17

Question
How does hydroxyurea work?
Answer
  • Destroys HbS
  • Stimulates production of HbF. HbF decreases polymer formation of HbS due to its high oxygen affinity
  • Stimulates production of HbF. HbF decreases polymer formation of HbS due to its low oxygen affinity.
  • Increases levels of HbA so there is a lower percentage of HbS in circulation

Question 18

Question
What should always be given with hydroyurea?
Answer
  • Vitamin B12
  • Folic acid
  • Iron
  • Normal RBCs

Question 19

Question
AJ is s 25 yo African American female who has sickle cell anemia and has had 2 severe pain crises in the past year. She is a good candidate for hydroxyurea.
Answer
  • True
  • False

Question 20

Question
If toxicity from hydroxyurea occurs, hydroxyurea should be D/C forever.
Answer
  • True
  • False

Question 21

Question
What is the only therapy that can cure sickle cell disease and should it be used for everyone?
Answer
  • Hydroxyurea; yes
  • Hydroxyurea; no
  • HSCT; yes
  • HSCT; no

Question 22

Question
Which of the following sickle cell complications result in an acute decrease in Hgb with decreased reticulocyte count and transient suppression of RBC production in response to bacterial or viral infection?
Answer
