A client who is diagnosed multiple myeloma experiences decreased production of red blood cells (RBCs). Which prescribed medication should the nurse prepare to administer to increase the production of erythrocytes?
- A. Filgrastim
- B. Pegfilgrastim
- C. Erythropoietin
- D. Dexamethasone
Correct Answer: C
Rationale: The medication erythropoietin can be used to stimulate the production of red blood cells; therefore, this is the prescribed medication that the nurse prepares to administer to the client. Filgrastim and pegfilgrastim promote proliferation of neutrophils, not erythrocytes. Dexamethasone is a corticosteroid that is prescribed for clients who are diagnosed with multiple myeloma to inhibit the inflammatory immune response.

The nurse reinforces education for a client who is diagnosed with a coagulopathy. Which client statement indicates a correct understanding of the definition for this disorder?
- A. My diagnosis means that I am missing or lacking components needed to control bleeding.
- B. My diagnosis is a bleeding disorder caused by a deficiency of globulins in my blood.
- C. My diagnosis is a bleeding disorder that involves red blood cells.
- D. My diagnosis means that I am at risk for developing blood clots.
Correct Answer: A
Rationale: The term coagulopathy refers to conditions in which a component that is necessary to control bleeding is missing or inadequate. Two common examples are thrombocytopenia and hemophilia. Coagulopathies do not involve red blood cells, nor are they characterized by a deficiency of globulins in the plasma.
The nurse is caring for four clients on the medical-surgical unit of the hospital. What client is mostly likely to be receiving treatment for sickle cell crisis?
- A. A 29-year-old Caucasian male
- B. A 19-year-old male of African descent
- C. A 24-year-old Native American/First Nations female
- D. A 36-year-old Eastern European female
Correct Answer: B
Rationale: Sickle cell disease is a common genetic disorder found primarily in clients of African descent but also in people from Mediterranean and Middle Eastern countries. It is unlikely that a Caucasian male, Native American/First Nations female, or eastern European female will be affected by this disease.
A client comes to the walk-in clinic complaining of weakness and fatigue. While assessing this client, the nurse finds evidence of petechiae and ecchymoses. The nurse notes that the spleen appears enlarged. What would the nurse suspect is wrong with this client?
- A. Aplastic anemia
- B. Pernicious anemia
- C. Iron-deficiency anemia
- D. Agranulocytosis
Correct Answer: A
Rationale: Clients with aplastic anemia experience all the typical characteristics of anemia (weakness and fatigue). In addition, they have frequent opportunistic infections plus coagulation abnormalities that are manifested by unusual bleeding, small skin hemorrhages called petechiae, and ecchymoses (bruises). The spleen becomes enlarged with an accumulation of the client's blood cells destroyed by lymphocytes that failed to recognize them as normal cells, or with an accumulation of dead transfused blood cells. The blood cell count shows insufficient numbers of blood cells. A bone marrow aspiration confirms that the production of stem cells is suppressed. This scenario does not describe a client with pernicious anemia, iron-deficiency anemia, or agranulocytosis.
The nurse observes the laboratory studies for a client in the hospital with fatigue, feeling cold all of the time, and hemoglobin of 8.6 g/dL and a hematocrit of 28%. What finding would be an indicator of iron-deficiency anemia?
- A. Erythrocytes that are microcytic and hypochromic
- B. Erythrocytes that are macrocytic and hyperchromic
- C. Clustering of platelets with sickled red blood cells
- D. An increased number of erythrocytes
Correct Answer: A
Rationale: A blood smear reveals erythrocytes that are microcytic (smaller than normal) and hypochromic (lighter in color than normal). It does not reveal macrocytic (larger than normal) or hyperchromic erythrocytes. Clustering of platelets with sickled red blood cells would indicate sickle cell anemia. An increase in the number of erythrocytes would indicate polycythemia vera.
The nurse is assigned to care for a client with polycythemia vera. When the nurse encourages the client to drink 3 L of fluid per day, the client states, 'Why do I have to drink so much?' What is the best response by the nurse?
- A. We don't want you to get dehydrated.
- B. It helps adequately hydrate you and ensures a sufficient urine production.
- C. It will help your heart beat regularly and effectively.
- D. It will help restrict blood circulation.
Correct Answer: B
Rationale: The client should be advised to drink 3 quarts (or liters) per day. Adequate hydration promotes venous return and ensures sufficient urine production. Informing the client that the healthcare team does not want them to get dehydrated does not address the rationale that the client requires. Fluid hydration will not help the heart beat regularly or more effectively and it will not help to restrict blood circulation.
