M.B. is a generally healthy 36-year-old woman with complaints of persistent generalized fatigue. At her annual checkup she is noted to have the following vital signs: heart rate 118 beats/min, blood pressure 128/60, oral temperature 37º C, and respiratory rate 26 breaths/min. Her skin and nail beds are pale. Laboratory results demonstrate hematocrit (Hct) 31%; hemoglobin (Hb) 10 g/dl; mean corpuscular hemoglobin concentration (MCHC) 27; mean corpuscular volume (MCV) 70; total iron binding capacity 600 mg/dl. What other history data would be helpful in determining the cause of this disorder? (select all that apply) A. Heavy menses or other source of chronic bleeding B. Joint pain C. Pale conjunctiva D. Abdominal pain

Step 1
Her skin and nail beds are pale, and laboratory results show low Hct and Hb levels, as well as low MCHC and MCV values. These findings suggest anemia, which could be caused by various factors. Option A, heavy menses or other sources of chronic bleeding, is a Show more…

He reported eating balanced diet of fruits, vegetables, meat, and dairy products. Physical examination, he appeared slightly pale but had no other abnormalities His laboratory results was following: Hemoglobin 12.5 g/dL Hematocrit 32% RBC 4.2 x 10^12/L WBC count within normal limits MCV 42 fL MCH 29.7 pg Urinalysis is normal Fecal occult blood found to be positive What is the most likely cause of this patient' anemia? 2- What type of red cell morphology would be expected on peripheral blood smear? What follow-up tests should be conducted? What do you expected the treatment for this patient would be? 5- What would you expected about the reticulocyte count to be for this patient? (Increase/ decrease/ normal)? Why?
