A nurse is caring for a patient with myelodysplastic syndrome (MDS) who is receiving erythropoietin therapy. What should the nurse monitor to evaluate the effectiveness of this treatment?
- A. Platelet count
- B. Hemoglobin level
- C. White blood cell count
- D. Oxygen saturation
Correct Answer: B
Rationale: Erythropoietin therapy is used to stimulate the production of red blood cells in patients with myelodysplastic syndrome (MDS), a disorder characterized by ineffective blood cell production, including red blood cells. The primary goal of erythropoietin therapy is to increase red blood cell count, improving the patient's oxygen-carrying capacity and reducing symptoms of anemia, such as fatigue and weakness. Monitoring hemoglobin levels is the best way to evaluate the effectiveness of this therapy because it directly reflects the patient's red blood cell count and the success of erythropoiesis (red blood cell production).

A nurse is planning care for a patient with leukemia who has been experiencing severe fatigue. What is the most appropriate intervention to include in the care plan?
- A. Encouraging the patient to remain in bed
- B. Scheduling frequent rest periods
- C. Providing a high-calorie diet
- D. Administering blood transfusions
Correct Answer: B
Rationale: In patients with leukemia, severe fatigue is a common symptom due to factors such as anemia, the disease process itself, and the effects of treatments like chemotherapy. The most appropriate intervention is to schedule frequent rest periods to help manage fatigue while encouraging a balance between rest and activity. This approach allows the patient to conserve energy for essential tasks and prevent exhaustion, without promoting complete inactivity, which can lead to deconditioning.
The nurse knows that all of the following are risk factors for breast cancer except:
- A. Family history
- B. Nulliparity
- C. Chest xray
- D. Multiple sex partners
Correct Answer: D
Rationale: Multiple sex partners are not a recognized risk factor for breast cancer. Breast cancer is primarily influenced by hormonal, genetic, and environmental factors, not sexual activity or the number of sexual partners. Established risk factors for breast cancer include family history, hormonal factors such as early menarche, late menopause, and nulliparity (having no children), as well as certain environmental exposures.
A nurse is caring for a patient with myelodysplastic syndrome (MDS) who is at risk for anemia. What is the most appropriate intervention to address this risk?
- A. Administering iron supplements
- B. Administering blood transfusions
- C. Providing a high-iron diet
- D. Administering erythropoietin
Correct Answer: D
Rationale: In myelodysplastic syndrome (MDS), the bone marrow does not produce enough healthy blood cells, leading to conditions such as anemia. Administering erythropoietin is an effective intervention to manage anemia in MDS patients because it stimulates the production of red blood cells. This can help improve the patient's hemoglobin levels, reducing symptoms such as fatigue and weakness associated with anemia. Erythropoietin is commonly used in MDS to enhance red blood cell production and reduce the need for frequent blood transfusions.
A nurse is planning the care of a patient who has been admitted to the medical unit with a diagnosis of multiple myeloma. In the patients care plan, the nurse has identified a diagnosis of Risk for Injury. What pathophysiologic effect of multiple myeloma most contributes to this risk?
- A. Labyrinthitis
- B. Left ventricular hypertrophy
- C. Decreased bone density
- D. Hypercoagulation
Correct Answer: C
Rationale: In multiple myeloma, the malignant proliferation of plasma cells within the bone marrow leads to the secretion of osteoclast-activating factors, which increase the breakdown of bone tissue (osteolysis). This results in decreased bone density, osteoporosis, and osteolytic lesions, making bones fragile and more prone to pathologic fractures. Patients with multiple myeloma are at high risk for fractures even with minimal trauma due to the weakened bone structure, which is why Risk for Injury is a key diagnosis.
A nurse working with oncology clients knows that an age-related decrease in which function increases the older client's susceptibility to infection during chemotherapy?
- A. Immune function.
- B. Kidney function.
- C. Liver function.
- D. Cardiac function.
Correct Answer: A
Rationale: As people age, the immune system becomes less efficient, a phenomenon known as immunosenescence. This decline in immune function includes reduced production of immune cells (such as T cells and B cells) and diminished responses to infections. During chemotherapy, which further suppresses the immune system, older clients are at a significantly higher risk of developing infections due to this age-related decrease in immune function. This is especially concerning because chemotherapy targets rapidly dividing cells, which include immune cells, making it even harder for the body to fight off infections.
