On Greg's last visit to his doctor, he complained of feeling tired. His doctor orders a blood test for iron. Sandra, the registered nurse, does a venipuncture and withdraws 8.0 mL of blood. About 70% of the iron in the body is used to form hemoglobin, which is a protein in the red blood cells that carries oxygen to the cells of the body. About 30% is stored in ferritin, bone marrow, and the liver. When the iron level is low, a person may have fatigue and decreased immunity. The normal range for serum iron in men is 80 to 160 mcg/dL. Greg's iron test showed a blood serum iron level of 42 mcg/dL, which indicates that Greg has iron deficiency anemia. His doctor orders an iron supplement to be taken twice daily (b.i.d.). One tablet of the iron supplement contains 110 mg of iron. Each tablet contains 110 mg of iron, which is given for iron supplementation. You may want to reference (Pages 49-52) Section 2.7 while Part C How many grams of iron will Greg consume in one week? Express the mass in grams to two significant figures. Provide Feedback
