Oncology Questions
1. A 54-year-old has a diagnosis of breast cancer and is tearfully discussing her diagnosis with the nurse. The patient states, 'They tell me my cancer is malignant, while my coworker's breast tumor was benign. I just don't understand at all.' When preparing a response to this patient, the nurse should be cognizant of what characteristic that distinguishes malignant cells from benign cells of the same tissue type?
- A. Slow rate of mitosis of cancer cells
- B. Different proteins in the cell membrane
- C. Differing size of the cells
- D. Different molecular structure in the cells
Correct answer: B
Rationale: The correct answer is B. Malignant cells have different proteins in their membranes, such as tumor-specific antigens, which distinguish them from benign cells. Choice A is incorrect as cancer cells typically have a rapid and uncontrolled rate of mitosis. Choice C is incorrect as the size of cells alone does not distinguish between malignant and benign cells. Choice D is incorrect as the molecular structure is not the primary characteristic that distinguishes between malignant and benign cells.
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. The cells of a normal individual can replicate in a specified rate. If the rate of replication becomes uncontrollable, which of the following is lacking from the patient?
- A. Apoptosis
- B. Contact inhibition
- C. Stable cells
- D. Labile cells
Correct answer: B
Rationale: Contact inhibition is a regulatory mechanism that prevents cells from proliferating once they reach a certain density. Normally, when cells grow and touch each other (such as in a monolayer), they stop dividing, maintaining tissue integrity and structure. When contact inhibition is lacking, as in many cancerous cells, cells continue to grow and divide uncontrollably, leading to tumor formation. This loss of regulation is a hallmark of cancerous growth.
4. Which of the following is a correct statement by the nurse to a patient under radiation therapy?
- A. Brachytherapy can be administered by a pregnant nurse
- B. Teletherapy makes the patient radioactive
- C. Brachytherapy is an internal radiation therapy
- D. Teletherapy requires proper disposal of feces since feces is not a source of radiation
Correct answer: C
Rationale: The correct statement is that Brachytherapy is an internal radiation therapy. Brachytherapy involves placing radioactive sources inside or near the tumor, delivering a high radiation dose to the targeted area while minimizing exposure to surrounding healthy tissues. Choices A and B are incorrect because pregnant nurses should not administer radiation therapy and brachytherapy does not make the patient radioactive. Choice D is incorrect as feces is not a source of radiation in teletherapy, and it does not require special disposal.
5. A client has a platelet count of 9800/mm3. What action by the nurse is most appropriate?
- A. Assess the client for calf pain, warmth, and redness.
- B. Instruct the client to call for help to get out of bed.
- C. Obtain cultures as per the facility’s standing policy.
- D. Place the client on protective Isolation Precautions.
Correct answer: B
Rationale: A platelet count of 9800/mm³ indicates severe thrombocytopenia, placing the client at high risk for bleeding, even with minor trauma or injury. Instructing the client to call for help before getting out of bed ensures they receive assistance with mobility, which reduces the risk of falls or injuries that could lead to serious bleeding. Preventing any activity that could result in trauma is crucial when managing clients with very low platelet counts.
