Pregunta 5
Pregunta
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].

Pregunta 17
Pregunta
How does hydroxyurea work?
Respuesta
-
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
