John James  is a 55 y/o man who had labs drawn prior to a yearly physical.  He is here for followup of results from labs drawn 2 weeks prior. He has no complaints except for occasional fatigue.  His CBC and an anemia panel reveals the following: Hemoglobin (Hb): 9.2 g/dL (Normal range for age: 11.0 – 13.5 g/dL Mean corpuscular volume (MCV): 68 fL (Normal range for age: 76 – 92 fL) Mean corpuscular hemoglobin concentration (MCHC):  low value Serum ferritin: 6 ng/mL (Normal range for age: 12 – 120 ng/mL) Serum iron: 15 µg/dL (Normal range for age: 40 – 100 µg/dL) Total iron-binding capacity (TIBC):490 µg/dL (Normal range for age: 250 – 450 µg/dL) 1-Based on the MCV and MCHC- What type of anemia is this and why does this anemia cause a low MCV? (2 points)  2-What lab reflects iron stores? (1) 3-Why is the TIBC high? (1) 4- List at least 2 possible differentials that may be causing his anemia. (1)

Let fx=x2-4{“version”:”1.1″,”math”:”fx=x2-4″} and gx=4-x2{“version”:”1.1″,”math”:”gx=4-x2″} .  Which interval represents the domain of the function f/gx{“version”:”1.1″,”math”:”f/gx”} ?

Consider the following simplification, where a{“version”:”1.1″,”math”:”a”} and b{“version”:”1.1″,”math”:”b”} represent real numbers: a – b2a2 – b2=a – ba – ba – ba + b=a – ba + b{“version”:”1.1″,”math”:”a - b2a2 - b2=a - ba - ba - ba + b=a - ba + b”} Although the simplification is symbolically correct, it should be followed by which additional statement(s) in order to be valid for all values of a{“version”:”1.1″,”math”:”a”} and b{“version”:”1.1″,”math”:”b”} ?
