A patient, diagnosed with leukemia, has minimal white blood cells. The nurse realizes that which of the following would be applicable for this patient?
1. infusion of red blood cells
2. infusion of fresh frozen plasma
3. immunizations
4. bone marrow transplant
4
Rationale: Blood cells include red cells, white cells, and platelets. All three of these elements of blood are created in the bone marrow. The patient with low white blood cells would benefit from a bone marrow transplant since each of these types of cells originates from a stem cell. A patient with minimal white blood cells would not benefit from an infusion of red blood cells or fresh frozen plasma. Individuals with low white blood cell counts usually do not receive immunizations.
