Chapter 54 : Anemia Drugs Questions
Question 1 of 5
A patient with end-stage renal failure has been admitted to the hospital for severe anemia. The patient is refusing blood transfusions. The nurse anticipates drug therapy with which drug to stimulate the production of red blood cells?
Correct Answer: C
Rationale: Epoetin alfa is a colony-stimulating factor that is responsible for erythropoiesis, or formation of red blood cells.
Question 2 of 5
A cancer patient is receiving drug therapy with epoetin alfa. The nurse knows that the medication must be stopped if which laboratory result is noted?
Correct Answer: B
Rationale: If epoetin is continued when hemoglobin levels are above 11 g/dL, patients may experience serious adverse events, including heart attack, stroke, and death. Caution must be used when hemoglobin levels are above 10 g/dL for cancer patients and 11 g/dL for renal patients.
Question 3 of 5
A patient has been receiving epoetin alfa for severe iron-deficiency anemia. Today, the provider changed the order to darbepoetin. The patient questions the nurse, 'What is the difference in these drugs?' Which response by the nurse is correct?
Correct Answer: D
Rationale: Darbepoetin (Aranesp) is longer-acting than epoetin alfa (Epogen); therefore, fewer injections are required.
Question 4 of 5
A patient will be taking oral iron supplements at home. The nurse will include which statements in the teaching plan for this patient? (Select all that apply.)
Correct Answer: A,E,G
Rationale: Iron tablets need to be taken with meals to reduce gastrointestinal distress, but antacids and milk interfere with absorption. Orange juice enhances the absorption of iron. Stools may become black and tarry in patients who are on iron supplements. Tablets need to be taken whole, not crushed, and the patient needs to be encouraged to eat foods high in iron.
Question 5 of 5
A 2-year-old child will be receiving ferrous sulfate oral drops (Fer-Iron) 5 mg/kg/day in three divided doses. The child weighs 30 pounds. Identify how many milligrams the nurse will administer per dose. (Record answer using one decimal place.)
Correct Answer: 22.7 mg
Rationale: Convert pounds to kilograms: 30 ?· 2.2 = 13.6 kg. Calculate the total dose per day: 5 mg/kg/day ?? 13.6 kg = 68 mg/day. Divide into 3 doses: 68 mg/day ?· 3 doses/day = 22.67, rounded to 22.7 mg/dose.
