ATI Oncology Questions
1. 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.
2. A client is diagnosed with multiple myeloma and the client asks the nurse about the diagnosis. The nurse bases the response on which description of this disorder?
- A. Altered red blood cell production
- B. Altered production of lymph nodes
- C. Malignant exacerbation in the number of leukocytes
- D. Malignant proliferation of plasma cells within the bone
Correct answer: D
Rationale: Multiple myeloma is a type of cancer that involves the malignant proliferation of plasma cells, which are a type of white blood cell that produces antibodies. In multiple myeloma, these abnormal plasma cells accumulate in the bone marrow, where they interfere with the production of normal blood cells and lead to the formation of tumors in the bones. This can cause bone pain, fractures, anemia, and impaired immune function. The excessive production of abnormal antibodies can also result in kidney damage and other systemic complications.
3. A client is receiving rituximab. What assessment by the nurse takes priority?
- A. Blood pressure.
- B. Temperature.
- C. Oral mucous membranes.
- D. Pain.
Correct answer: A
Rationale: When a client is receiving rituximab, the nurse's priority assessment should be monitoring the blood pressure. Rituximab can lead to infusion-related reactions, such as hypotension. Therefore, assessing the client's blood pressure is crucial to detect and manage any potential adverse reactions promptly. While monitoring temperature, oral mucous membranes, and pain are essential aspects of care, they are not the priority when a client is receiving rituximab.
4. While a patient is receiving IV doxorubicin hydrochloride for the treatment of cancer, the nurse observes swelling and pain at the IV site. The nurse should prioritize what action?
- A. Stopping the administration of the drug immediately
- B. Notifying the patient's physician
- C. Continuing the infusion but decreasing the rate
- D. Applying a warm compress to the infusion site
Correct answer: A
Rationale: The correct action for the nurse to take when observing swelling and pain at the IV site during the administration of doxorubicin hydrochloride is to stop the administration of the drug immediately. Doxorubicin hydrochloride can cause severe tissue damage, so discontinuing the infusion is crucial to prevent further harm to the patient. Notifying the physician is important, but it should not take precedence over stopping the drug. Continuing the infusion, even at a decreased rate, can exacerbate tissue damage. Applying a warm compress is not appropriate in this situation and may worsen the tissue injury caused by the drug.
5. A client is receiving rituximab and asks how it works. What response by the nurse is best?
- A. It causes rapid lysis of the cancer cell membranes.
- B. It destroys the enzymes needed to create cancer cells.
- C. It prevents the start of cell division in the cancer cells.
- D. It sensitizes certain cancer cells to chemotherapy.
Correct answer: C
Rationale: Rituximab is a monoclonal antibody that targets CD20, a protein found on the surface of certain B-cells, including some cancerous B-cells, such as in non-Hodgkin's lymphoma and chronic lymphocytic leukemia (CLL). Rituximab works by binding to the CD20 protein, which leads to the destruction of the cancerous B-cells through various mechanisms, including preventing the initiation of cell division. By blocking the division process, rituximab helps slow the growth and proliferation of cancer cells, allowing the immune system and additional treatments to clear them more effectively.
