Question
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 8.0mL 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.
Enter an equality for one tablet of the iron supplemen
Explanation / Answer
100 mg iron / supplement = 100 mg x (1000 mcg / 1 mg) / supplement = 105 mcg / supplement
