Nursing Elites

1. A patient who is receiving methotrexate for severe rheumatoid arthritis develops a megaloblastic anemia. The nurse will anticipate teaching the patient about increasing oral intake of

• A. iron.
• B. folic acid.
• C. cobalamin (vitamin B12).
• D. ascorbic acid (vitamin C).

Correct answer: C

Rationale: The correct answer is C: cobalamin (vitamin B12). Methotrexate can lead to a deficiency in cobalamin, resulting in megaloblastic anemia. Therefore, increasing the oral intake of cobalamin is essential to address this deficiency. Choice A, iron, is incorrect because megaloblastic anemia caused by methotrexate is not typically due to iron deficiency. Choice B, folic acid, is also incorrect as methotrexate does not directly cause folic acid deficiency. Choice D, ascorbic acid (vitamin C), is incorrect as it is not directly related to megaloblastic anemia caused by methotrexate; instead, cobalamin is the key vitamin that needs attention.

2. The nurse is caring for a patient post-coronary artery bypass graft procedure who is on a nitroglycerin intravenous drip. The nurse understands the importance of nitroglycerin with this procedure as:

• A. Decreasing myocardial oxygen supply.
• B. Increasing preload.
• C. Decreasing cardiac output.
• D. Decreasing afterload.

Correct answer: D

Rationale: Nitroglycerin is a vasodilator that works by decreasing afterload, which is the pressure the heart must work against to eject blood during systole. By reducing afterload, nitroglycerin helps the heart pump more effectively and decreases the workload on the heart. This results in improved cardiac output and decreased myocardial oxygen demand. Choices A, B, and C are incorrect because nitroglycerin does not decrease myocardial oxygen supply, increase preload, or decrease cardiac output.

3. Which laboratory test will the nurse use to determine whether filgrastim (Neupogen) is effective for a patient with acute lymphocytic leukemia who is receiving chemotherapy?

• A. Platelet count
• B. Reticulocyte count
• C. Total lymphocyte count
• D. Absolute neutrophil count

Correct answer: D

Rationale: The correct answer is D, Absolute neutrophil count. Filgrastim (Neupogen) works by stimulating the production and function of neutrophils. Therefore, monitoring the Absolute neutrophil count is crucial to assess the effectiveness of filgrastim in increasing neutrophil levels. Choices A, B, and C are incorrect because platelet count, reticulocyte count, and total lymphocyte count do not directly reflect the effectiveness of filgrastim in increasing neutrophils, which are essential in fighting infections during chemotherapy.

4. A postoperative patient receiving a transfusion of packed red blood cells develops chills, fever, headache, and anxiety 35 minutes after the transfusion is started. After stopping the transfusion, what action should the nurse take?

• A. Give the PRN diphenhydramine
• B. Send a urine specimen to the laboratory
• C. Administer PRN acetaminophen (Tylenol)
• D. Draw blood for a new type and crossmatch

Correct answer: C

Rationale: The patient’s clinical manifestations are consistent with a febrile, nonhemolytic transfusion reaction. The transfusion should be stopped and antipyretics administered for the fever as ordered.

5. An appropriate nursing intervention for a patient with non-Hodgkin's lymphoma whose platelet count drops to 18,000/µL during chemotherapy is to

• A. check all stools for occult blood
• B. encourage fluids to 3000 mL/day
• C. provide oral hygiene every 2 hours
• D. check the temperature every 4 hours

Correct answer: A

Rationale: The correct answer is to check all stools for occult blood. With a platelet count of 18,000/µL, the patient is at a high risk of spontaneous bleeding. Checking stools for occult blood can help detect any internal bleeding early. Encouraging fluids and providing oral hygiene are important interventions in general, but in this case, monitoring for bleeding takes precedence. Checking the temperature every 4 hours is not directly related to the patient's current condition and platelet count.
