A nurse is preparing to administer ferrous sulfate to a patient. For which condition is the nurse administering this medication for?

A. Anemia: Ferrous sulfate is an iron supplement used to treat iron-deficiency anemia. It provides the iron needed for hemoglobin synthesis, which increases red blood cell production and improves oxygen-carrying capacity. B. Hypertension: Ferrous sulfate has no effect on blood pressure. Antihypertensive medications, such as ACE inhibitors or beta-blockers, are used to manage hypertension. C. Hyperthyroidism: Ferrous sulfate does not treat thyroid disorders. Hyperthyroidism requires medications that regulate thyroid hormone production, such as methimazole or propylthiouracil. D. Rheumatoid Arthritis: Ferrous sulfate is not indicated for autoimmune or inflammatory conditions like rheumatoid arthritis. Disease-modifying antirheumatic drugs (DMARDs) or biologics are typically used instead.
