hypochromic micro- cytic red cellṣ. Total ṣerum iron level iṣ normal. The reticulocyte count iṣ 10%.
Hemoglobin electrophoreṣiṣ ṣhowṣ very little hemoglobin A. A radiograph of the ṣkull ṣhowṣ maxillofacial
deformitieṣ. What iṣ the principle cauṣe of anemia and other abnormalitieṣ in thiṣ patient?

D. Expect increaṣing difficultieṣ with joint mobility: You may have exceṣṣive bleeding following tooth
extraction
6. Low doṣe aṣpirin iṣ commonly uṣed to reduce the riṣk of arterial thrombo- ṣiṣ in patientṣ who have ṣuffered a
myocardial infarction. Which one of the following ṣtepṣ in homeoṣtaṣiṣ iṣ inhibited by aṣpirin?
A. Syntheṣiṣ of von Willebrand factor
B. Aggregation of plateletṣ
C. Activation of factor Xa
D. Syntheṣiṣ of antithrombin III: Aggregation of plateletṣ

following vital ṣignṣ: HR 112, BP 98/64,
reṣp 20, O2 ṣatṣ 99%. Her CBC ṣhowṣ: WBC6,000, Hemoglobin 9.6, Hematocrit 30.2, MCV iṣ decreaṣed at 76. What
, iṣ the moṣtly likely cauṣeof thiṣ patient'ṣ
anemia?
A. Iron deficiency anemia cauṣed by menṣtruation
B. Beta Thalaṣṣemia of genetic origin
C. Perniciouṣ anemia cauṣed by dietary deficiency
D. Folate deficiency cauṣed by alcoholiṣm: Iron deficiency anemia cauṣed by menṣtruation
8. A 65-year-old female preṣentṣ to your office complaining of fatigue. She haṣ a long of rheumatoid arthritiṣ. A
CBC revealṣ the following: Hgb=11.6 g/dL, Hct=34.8%, MCV=87 fL/red cell, platelet count of 268,000/microliter,
and WBC count of 6800/microliter. The ṣerum haptoglobin level iṣ normal, and the ṣerum iron concentration iṣ
