The nurse is caring for a patient who has a history of a transfusion-related acute lung injury (TRALI) and is to receive a transfusion of packed red blood cells (PRBCs). Which of the following actions should the nurse take to decrease the risk for TRALI for this patient?
- A. Infuse the PRBCs slowly over 4 hours.
- B. Transfuse only leukocyte-reduced PRBCs.
- C. Administer the scheduled oral diuretic before the transfusion.
- D. Give the PRN dose of antihistamine before starting the transfusion.
Correct Answer: B
Rationale: TRALI is caused by a reaction between the donor and the patient leukocytes that causes pulmonary inflammation and capillary leaking. The other actions may help prevent respiratory condition caused by circulatory overload or by allergic reactions, but they will not prevent TRALI.

Which of the following assessment data obtained by the nurse when caring for a patient with thrombocytopenia should be immediately communicated to the health care provider?
- A. The platelet count is 52 x 10^9/L.
- B. The patient is difficult to arouse.
- C. There are large bruises on the back.
- D. There are purpura on the oral mucosa.
Correct Answer: B
Rationale: Difficulty in arousing the patient may indicate a cerebral hemorrhage, which is life-threatening and requires immediate action. The other information should be documented and reported, but would not be unusual in a patient with thrombocytopenia.
The nurse is caring for a patient with anemia who is experiencing increased fatigue and occasional palpitations at rest. Which of the following laboratory findings should the nurse expect?
- A. Normal red blood cell (RBC) indices
- B. Hematocrit (Hct) of 38%
- C. Hemoglobin (Hb) of 86 g/L
- D. RBC count of 4.5 x 10^12/L
Correct Answer: C
Rationale: The patient's clinical manifestations indicate moderate anemia, which is consistent with an Hb of 60-100 g/L. The other values are all within the range of normal.
All of these patients call the outpatient clinic and ask to make an appointment as soon as possible. Which of the following patients should the nurse schedule to be seen first?
- A. 19-year-old with no previous health problems who has a nontender lump in the axilla
- B. 46-year-old with sickle cell anemia who says 'that my eyes always look sort of yellow'
- C. 21-year-old with hemophilia who wants to learn how to self-administer factor VII replacement
- D. 50-year-old with early-stage persistent lymphocytic leukemia who has complaints of persistent fatigue
Correct Answer: A
Rationale: The patient's age and presence of a nontender axillary lump suggest possible lymphoma, which needs rapid diagnosis and treatment. The other patients have questions about treatment or symptoms that are consistent with their diagnosis but do not need to be seen urgently.
Which of the following laboratory information should the nurse monitor to detect heparin-induced thrombocytopenia (HIT) in a patient who is receiving a continuous heparin infusion?
- A. Prothrombin time
- B. Erythrocyte count
- C. Fibrinogen degradation products
- D. Activated partial thromboplastin time
Correct Answer: D
Rationale: Platelet aggregation in HIT causes neutralization of heparin so that the activated partial thromboplastin time will be shorter and more heparin will be needed to maintain therapeutic levels. The other data will not be affected by HIT.
Which of the following laboratory tests should the nurse use to determine whether the prescribed filgrastim is effective in the treatment of a patient who is receiving chemotherapy for acute lymphocytic leukemia?
- A. Platelet count
- B. Reticulocyte count
- C. Total lymphocyte count
- D. Absolute neutrophil count
Correct Answer: D
Rationale: Filgrastim increases the neutrophil count and function in neutropenic patients. Although total lymphocyte, platelet, and reticulocyte counts also are important to monitor in this patient, the absolute neutrophil count is used to evaluate the effects of filgrastim.
