if there is food in the stomach. Iron requires an acid environment to facilitate its
               absorption in the duodenum. Iron is not added to formula or mixed with cereal or
               other food items.
                  Test-Taking Strategy: Eliminate options 3 and 4 first because they are comparable
               or alike and because medication should not be added to formula and food. Next,
               note the word liquid in the question. This should assist you in recalling that iron in
               liquid form stains teeth.

                  Rationale: In iron deficiency anemia, iron stores are depleted, resulting in a
               decreased supply of iron for the manufacture of hemoglobin in red blood cells. The
               results of a complete blood cell count in children with iron deficiency anemia show
               decreased hemoglobin levels and microcytic and hypochromic red blood cells. The
               red blood cell count is decreased. The reticulocyte count is usually normal or slightly
               elevated.
                  Test-Taking Strategy: Focus on the subject, laboratory findings. Eliminate options
               1 and 3 first, knowing that the hemoglobin and red blood cell counts would be
               decreased. From the remaining options, select the correct option over option 2
               because of the relationship between anemia and red blood cells.

                  Rationale: Sickle cell anemia is one of a group of diseases termed
               hemoglobinopathies, in which hemoglobin A is partly or completely replaced by
               abnormal sickle hemoglobin S. It is caused by the inheritance of a gene for a
               structurally abnormal portion of the hemoglobin chain. Hemoglobin S is sensitive to
               changes in the oxygen content of the red blood cell; insufficient oxygen causes the
               cells to assume a sickle shape, and the cells become rigid and clumped together,
               obstructing capillary blood flow. Oral and intravenous fluids are an important part
               of treatment. Meperidine is not recommended for a child with sickle cell disease
               because of the risk for normeperidine-induced seizures. Normeperidine, a
               metabolite of meperidine, is a central nervous system stimulant that produces
