Description

Chapter 54: Anemia Drugs Lilley: Pharmacology and the Nursing Process, 8th Edition MULTIPLE CHOICE 1. A patient is to receive iron dextran injections. Which technique is appropriate when the nurse

is administering this medication? a. Intravenous administration mixed with 5% dextrose b. Intramuscular injection in the upper arm c. Intramuscular injection using the Z-track method d. Subcutaneous injection into the abdomen

ANS: C

Intramuscular iron is given using the Z-track method deep into a large muscle mass. If given intravenously, it is given with normal saline, not 5% dextrose. DIF: COGNITIVE LEVEL: Applying (Application) REF: p. 869 TOP: NURSING PROCESS: Implementation MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 2. A nurse is giving instructions to a patient who will be receiving oral iron supplements. Which

instructions will be included in the teaching plan? a. Take the iron tablets with milk or antacids. b. Crush the pills as needed to help with swallowing. c. Take the iron tablets with meals if gastrointestinal distress occurs. d. If black tarry stools occur, report it to the doctor immediately.

ANS: C

Although taking iron tablets with food may decrease absorption, doing so helps to reduce gastrointestinal distress. Antacids and milk may cause decreased iron absorption; iron tablets must be taken whole and not crushed. Black, tarry stools are expected adverse effects of oral iron supplements. DIF: COGNITIVE LEVEL: Applying (Application) REF: p. 868 TOP: NURSING PROCESS: Implementation MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 3. The nurse will teach a patient who is receiving oral iron supplements to watch for which

expected adverse effects? a. Palpitations b. Drowsiness and dizziness c. Black, tarry stools d. Orange-red discoloration of the urine

ANS: C

Black, tarry stools and other gastrointestinal disturbances may occur with the administration of iron preparations. The other options are incorrect. DIF: COGNITIVE LEVEL: Understanding (Comprehension) REF: p. 865 TOP: NURSING PROCESS: Assessment MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 4. A patient has been taking iron supplements for anemia for 2 months. During a follow-up

assessment, the nurse will observe for which therapeutic response? a. Decreased weight b. Increased activity tolerance c. Decreased palpitations d. Increased appetite

ANS: B

Absence of fatigue, increased activity tolerance and well-being, and improved nutrition status are therapeutic responses to iron supplementation. The other options are incorrect. DIF: COGNITIVE LEVEL: Applying (Application) REF: p. 869 TOP: NURSING PROCESS: Evaluation MSC: NCLEX: Physiological Integrity: Physiological Adaptation 5. An oral iron supplement is prescribed for a patient. The nurse would question this order if the

patient’s medical history includes which condition? a. Decreased hemoglobin b. Hemolytic anemia c. Weakness d. Concurrent therapy with erythropoietics

ANS: B

Hemolytic anemia is a contraindication to the use of iron supplements. Decreased hemoglobin and weakness are related to iron-deficiency anemia. Iron supplements are given with erythropoietic drugs to aid in the production of red blood cells. DIF: COGNITIVE LEVEL: Applying (Application) REF: p. 865 TOP: NURSING PROCESS: Assessment MSC: NCLEX: Physiological Integrity: Reduction of Risk Potential 6. The nurse is reviewing the medical record of a patient before giving a new order for iron

sucrose (Venofer). 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.

ANS: D

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. Low-weight elderly patients appear to be at greatest risk for hypotension. DIF: COGNITIVE LEVEL: Applying (Application) REF: p. 866 TOP: NURSING PROCESS: Implementation MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 7. The nurse is teaching a patient with iron-deficiency anemia about foods to increase iron

intake. Which food may enhance the absorption of oral iron forms? a. Milk b. Yogurt c. Antacids d. Orange juice

ANS: D

Orange juice contains ascorbic acid, which enhances the absorption of oral iron forms; antacids, milk, and yogurt may interfere with absorption. DIF: COGNITIVE LEVEL: Understanding (Comprehension) REF: p. 867 TOP: NURSING PROCESS: Implementation MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 8. The nurse is administering liquid oral iron supplements. Which intervention is appropriate

when administering this medication? a. Have the patient take the liquid iron with milk. b. Instruct the patient to take the medication through a plastic straw. c. Have the patient sip the medication slowly. d. Have the patient drink the medication, undiluted, from the unit-dose cup.

ANS: B

Liquid oral forms of iron need to be taken through a plastic straw to avoid discoloration of tooth enamel. Milk may decrease absorption. DIF: COGNITIVE LEVEL: Applying (Application) REF: p. 868 TOP: NURSING PROCESS: Implementation MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies

A woman who is planning to become pregnant should ensure that she receives adequate levels of which supplement to reduce the risk for fetal neural tube defects?

a. b. c. d.

Vitamin B12 Vitamin D Iron Folic acid

ANS: D

It is recommended that administration of folic acid be begun at least 1 month before pregnancy and continue through early pregnancy to reduce the risk for fetal neural tube defects. DIF: COGNITIVE LEVEL: Understanding (Comprehension) REF: p. 866 TOP: NURSING PROCESS: Planning MSC: NCLEX: Physiological Integrity: Reduction of Risk Potential 10. The nurse is administering folic acid to a patient with a new diagnosis of anemia. Which

statement about treatment with folic acid is true? a. Folic acid is used to treat any type of anemia. b. Folic acid is used to treat iron-deficiency anemia. c. Folic acid is used to treat pernicious anemia. d. The specific cause of the anemia needs to be determined before treatment.

ANS: D

Folic acid should not be used to treat anemias until the underlying cause and type of anemia have been identified. Administering folic acid to a patient with pernicious anemia may correct the hematologic changes of anemia, but the symptoms of pernicious anemia (which is due to a vitamin B12  deficiency, not a folic acid deficiency) may be deceptively masked. The other options are incorrect. DIF: COGNITIVE LEVEL: Applying (Application) REF: p. 867 TOP: NURSING PROCESS: Planning MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 11. During therapy with the hematopoietic drug epoetin alfa (Epogen), the nurse instructs the

patient about adverse effects that may occur, such as: a. anxiety. b. drowsiness. c. hypertension. d. constipation.

ANS: C

Hypertension is an adverse effect of hematopoietic drugs, along with headache, fever, pruritus, rash, nausea, vomiting, arthralgia, cough, and injection site reaction. The other options are incorrect.

DIF: COGNITIVE LEVEL: Understanding (Comprehension) REF: p. 863 TOP: NURSING PROCESS: Implementation MSC: NCLEX: Physiological Integrity: Basic Care and Comfort 12. The nurse is administering intravenous iron dextran for the first time to a patient with anemia.

After giving a test dose, how long will the nurse wait before administering the remaining portion of the dose? a. 30 minutes b. 1 hour c. 6 hours d. 24 hours

ANS: B

Although anaphylactic reactions usually occur within a few moments after the test dose, it is recommended that a period of at least 1 hour elapse before the remaining portion of the initial dose is given. The other options are incorrect. DIF: COGNITIVE LEVEL: Understanding (Comprehension) REF: p. 866 TOP: NURSING PROCESS: Planning MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 13. A patient with end-stage renal failure has been admitted to the hospital for severe anemia. She

is refusing blood transfusions. The nurse anticipates drug therapy with which drug to stimulate the production of red blood cells? a. Folic acid b. Cyanocobalamin (vitamin B12) c. Epoetin alfa (Epogen) d. Filgrastim (Neupogen)

ANS: C

Epoetin alfa is a colony-stimulating factor that is responsible for erythropoiesis, or formation of red blood cells. The other options are incorrect. DIF: COGNITIVE LEVEL: Understanding (Comprehension) REF: p. 863 TOP: NURSING PROCESS: Planning MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 14. A cancer patient is receiving drug therapy with epoetin alfa (Epogen). The nurse knows that

the medication must be stopped if which laboratory result is noted? a. White blood cell count of 550 cells/mm3 b. Hemoglobin level of 12 g/dL c. Potassium level of 4.2 mEq/L d. Glucose level of 78 mg/dL

ANS: B

If epoetin is continued when hemoglobin levels are above 11 g/dL, patients may experience serious adverse events, including heart attack, stroke, and death. Guidelines now recommend that the drug be stopped when the hemoglobin level reaches 10 g/dL for cancer patients. For renal patients, the target hemoglobin level is 11 g/dL for patients on dialysis and 10 g/dL for chronic renal patients not on dialysis. DIF: COGNITIVE LEVEL: Analyzing (Analysis) REF: p. 863 TOP: NURSING PROCESS: Evaluation MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 15. A patient has been receiving epoetin alfa (Epogen) for severe iron-deficiency anemia. Today,

the provider changed the order to darbepoetin (Aranesp). The patient questions the nurse, “What is the difference in these drugs?” Which response by the nurse is correct? a. “There is no difference in these two drugs.” b. “Aranesp works faster than Epogen to raise your red blood cell count.” c. “Aranesp is given by mouth, so you will not need to have injections.” d. “Aranesp is a longer-acting form, so you will receive fewer injections.”

ANS: D

Darbepoetin (Aranesp) is longer-acting than epoetin alfa (Epogen); therefore, fewer injections are required. The other options are incorrect. DIF: COGNITIVE LEVEL: Applying (Application) REF: p. 863 TOP: NURSING PROCESS: Implementation MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies MULTIPLE RESPONSE 1. 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 . ) a. Take the iron tablets with meals. b. Take the iron tablets on an empty stomach 1 hour before meals. c. Take the iron tablets with an antacid to prevent heartburn. d. Drink 8 ounces of milk with each iron dose. e. Taking iron supplements with orange juice enhances iron absorption. f. Stools may become loose and light in color. g. Stools may become black and tarry. h. Tablets may be crushed to enhance iron absorption.

ANS: A, E, G

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.
