Question 1
POST-QUESTIONS 1. In order to treat a patient, you may have to remove iron from a solution. If you have a 25 mL solution that contains 43 ug/dL of iron, how much deferoxamine would you need to administer to reach a concentration of 23 ug/dL? 2. In order to treat a patient, you may have to add iron to a solution. If you have 25 mL of a solution that contains 15 ug/dL, how many grams of iron (II) sulfate must be administered to reach a concentration of 23 pg/dL? 3. In medical laboratories, spectrophotometers are used to determine the concentration of hemoglobin (Hb) in patients. Normal human levels of Hb in Blood are between 13-18 g Hb/ 100 mL for males and 12-16 g Hb/ 100 mL for females. The analysis occurs by first creating standards. The blood sample from the patient is then diluted by 50% before determining the absorbance in the spectrophotometer. Using your prior knowledge, Excel, and the information below, determine if this male patient has normal levels of hemoglobin (do not forget about the dilution). Standard Hemoglobin Concentration (g Hb/ 100 mL) 4.00 Absorbance 1 0.188 8.00 0.375 3 12.0 0.625 4. 16.0 0.876 20.0 1.297 Unk. 0.537 Make sure you turn in your graph and calculations
