Chapter 31 : Caring for Clients With Disorders of the Hematopoietic System Questions
Question 1 of 5
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?
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.
Question 2 of 5
The nurse is instructing a client about taking a liquid iron preparation for the treatment of iron-deficiency anemia. What should the nurse include in the instructions?
Correct Answer: C
Rationale: Dilute liquid preparations of iron with another liquid such as juice and drink with a straw to avoid staining the teeth. Avoid taking iron simultaneously with an antacid, which interferes with iron absorption. Drink orange juice or take other forms of vitamin C with iron to promote its absorption. Expect iron to color stool dark green or black.
Question 3 of 5
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?
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.
Question 4 of 5
A client is seen in the emergency department with severe pain related to a sickle cell crisis. What does the nurse understand is occurring with this client?
Correct Answer: D
Rationale: The person with sickle cell disease repeatedly suffers from two major problems: (1) episodes of sickle cell crisis from vascular occlusion, which develops rapidly under hypoxic conditions, and (2) chronic hemolytic anemia. During a sickle cell crisis, the sickle-shaped cells lodge in small blood vessels, where they block the flow of blood and oxygen to the affected tissue. The vascular occlusion induces severe pain in the ischemic tissue. The client may have increased tolerance for pain due to the chronic nature of the illness. Bone marrow increases the erythrocyte production. Underhydration increases the client's risk of developing a vaso-occlusive crisis.
Question 5 of 5
A client with sickle cell disease informs the nurse that he is having chest pain. The nurse hears the client coughing, wheezing, and breathing rapidly. What does the nurse suspect is occurring with this client?
Correct Answer: C
Rationale: One of the unique manifestations of sickle cell disease is 'acute chest syndrome,' a type of pneumonia triggered by decreased hemoglobin and infiltrates in the lungs. Acute chest syndrome is characterized by respiratory symptoms, such as coughing, wheezing, tachypnea, and chest pain. Vaso-occlusive crisis causes decrease in tissue perfusion and predisposes the client to pneumonia but is not the present problem with this client. Pneumocystis pneumonia is present in the client with HIV/AIDS or other immunocompromised clients. The client's symptoms do not correlate with a diagnosis of acute muscular strain.
