A nurse is caring for a young female adult client who reports weakness, fatigue, and heavy menstrual periods. The client has a hemoglobin level of 8 g/dL and a hematocrit level of 28 g/dL. The nurse suspects which of the following types of anemia?

The correct answer is C: Iron deficiency anemia. The client's low hemoglobin and hematocrit levels indicate a decrease in red blood cells, which is characteristic of anemia. Iron deficiency anemia is the most common type of anemia, typically caused by inadequate iron intake or absorption, leading to decreased production of hemoglobin. This results in symptoms like weakness, fatigue, and heavy menstrual periods, as seen in the client. Pernicious anemia (A) is due to vitamin B12 deficiency, not iron. Folic acid deficiency anemia (B) presents with similar symptoms but typically has normal iron levels. Sickle cell anemia (D) is a genetic disorder causing abnormal hemoglobin production, not related to iron deficiency.
