- A. Decreased hemoglobin
- B. Hemolytic anemia
- C. Weakness
- D. Concurrent therapy with erythropoietics
Correct Answer: B

The nurse is reviewing the medical record of a patient before giving a new order for iron sucrose. Which statement regarding the administration of iron sucrose is correct?
- A. The medication is given with food to reduce gastric distress.
- B. Iron sucrose is contraindicated if the patient has renal disease.
- C. A test dose will be administered before the full dose is given.
- D. The nurse will monitor the patient for hypotension during the infusion.
Correct Answer: D
Rationale: Iron sucrose (Venofer) is an injectable iron product indicated for the treatment of iron-deficiency anemia in patients with chronic renal disease. It is also used for patients without kidney disease. Its risk of precipitating anaphylaxis is much less than that of iron dextran, and a test dose is not required. Hypotension is the most common adverse effect and appears to be related to infusion rate.
