A patients electronic health record states that the patient receives regular transfusions of factor IX. The nurse would be justified in suspecting that this patient has what diagnosis?
- A. Leukemia
- B. Hemophilia
- C. Hypoproliferative anemia
- D. Hodgkins lymphoma
Correct Answer: B
Rationale: Administration of clotting factors is used to treat diseases where these factors are absent or insufficient; hemophilia is among the most common of these diseases. Factor IX is not used in the treatment of leukemia, lymphoma, or anemia.

A patient has been diagnosed with a lymphoid stem cell defect. This patient has the potential for a problem involving which of the following?
- A. Plasma cells
- B. Neutrophils
- C. Red blood cells
- D. Platelets
Correct Answer: A
Rationale: A defect in a myeloid stem cell can cause problems with erythrocyte, leukocyte, and platelet production. In contrast, a defect in the lymphoid stem cell can cause problems with T or B lymphocytes, plasma cells (a more differentiated form of B lymphocyte), or natural killer (NK) cells.
The nurse is planning the care of a patient with a nutritional deficit and a diagnosis of megaloblastic anemia. The nurse should recognize that this patients health problem is due to what?
- A. Production of inadequate quantities of RBCs
- B. Premature release of immature RBCs
- C. Injury to the RBCs in circulation
- D. Abnormalities in the structure and function RBCs
Correct Answer: D
Rationale: Vitamin B12 and folic acid deficiencies are characterized by the production of abnormally large erythrocytes called megaloblasts. Because these cells are abnormal, many are sequestered (trapped) while still in the bone marrow, and their rate of release is decreased. Some of these cells actually die in the marrow before they can be released into the circulation. This results in megaloblastic anemia. This pathologic process does not involve inadequate production, premature release, or injury to existing RBCs.
A patient lives with a diagnosis of sickle cell anemia and receives frequent blood transfusions. The nurse should recognize the patients consequent risk of what complication of treatment?
- A. Hypovolemia
- B. Vitamin B12 deficiency
- C. Thrombocytopenia
- D. Iron overload
Correct Answer: D
Rationale: Patients with chronic transfusion requirements can quickly acquire more iron than they can use, leading to iron overload. These individuals are not at risk for hypovolemia and there is no consequent risk for low platelet or vitamin B12 levels.
The nurses review of a patients most recent blood work reveals a significant increase in the number of band cells. The nurses subsequent assessment should focus on which of the following?
- A. Respiratory function
- B. Evidence of decreased tissue perfusion
- C. Signs and symptoms of infection
- D. Recent changes in activity tolerance
Correct Answer: C
Rationale: Ordinarily, band cells account for only a small percentage of circulating granulocytes, although their percentage can increase greatly under conditions in which neutrophil production increases, such as infection. This finding is not suggestive of problems with oxygenation and subsequent activity intolerance.
A patient on the medical unit is receiving a unit of PRBCs. Difficult IV access has necessitated a slow infusion rate and the nurse notes that the infusion began 4 hours ago. What is the nurses most appropriate action?
- A. Apply an icepack to the blood that remains to be infused.
- B. Discontinue the remainder of the PRBC transfusion and inform the physician.
- C. Disconnect the bag of PRBCs, cool for 30 minutes and then administer.
- D. Administer the remaining PRBCs by the IV direct (IV push) route.
Correct Answer: B
Rationale: Because of the risk of infection, a PRBC transfusion should not exceed 4 hours. Remaining blood should not be transfused, even if it is cooled. Blood is not administered by the IV direct route.
