35-C
36-A
Because the patient is male and the energy is low (G6PD is responsible for energy)
BUT other information can see it in many conditions
A- IREs will be upregulated and attach to the 3`UTR of Tf mRNA.
B- IREs will be upregulated and attach to the 5`UTR of ferritin mRNA.
C- HRI kinase will be upregulated and phosphorylates eIF-2α.
D- HRI kinase will be downregulated and dephosphorylates eIF-2α.
E- None of the above is a correct answer.
36- A 16-year-old boy has had a low energy level. On physical examination he has an enlarged spleen. A CBC shows Hb of 8.8 g/dL, Hct 24.1%, MCV 65, PLT count 187x109/L, and WBC count 7.4x109/L. His serum ferritin is 3740 ng/mL (very high). A BM biopsy is performed and on microscopic examination reveals a M:E ratio of 1:4, and there is 4+ BM stainable iron. Which of the following is the most likely diagnosis?
36- B (شوفوا الـ MCV نازل وشوفوا الـ Ferritin عالي جدا لأنه في الثلاسيميا هناك تجمع للحديد وهو احد المخاطر التي نحاول ان نعالجها ونتفاداها، والحديد في BM مليان وكل هذا لا نراه في اي مرض آخر من المذكورة في السؤال. G6PD def. الـ MCV طبيعي او عالي شوي وفي الـ Sickle cell anemia برضوا الـ MCV طبيعي والـ Hereditary spherocytosis نفس الشيء

37- Automated hematocrit is:
A] More than measured HCT.
B] Less than manual PCV.
C] Same as manual HCT.
D] Unrelated to each other.
E] Non of the above.
38- Erroneous manual HCT determination can be caused by:
A] Adequate mixing of the blood.
B] Inclusion of buffy coat height in calculations.
C] Reduced trapped plasma.
D] Normocytic RBCs.
E] Extracentrifugation time

37-B
Because in manual procedure Trapped Plasma increase the value of HCT
38-B
buffy coat contain WBC and PLT. SO false increased the value of HCT
but extracentrifugation time not affected.
