Traditionally, nurses have been involved with tertiary cancer prevention. However, an increasing emphasis is being placed on both primary and secondary prevention. What would be an example of primary prevention?
- A. Yearly Pap tests
- B. Testicular self-examination
- C. Teaching patients to wear sunscreen
- D. Screening mammograms
Correct Answer: C
Rationale: Primary prevention involves actions taken to reduce the risk of developing cancer by preventing exposure to known risk factors or promoting healthy behaviors. Teaching patients to wear sunscreen is an example of primary prevention because it aims to reduce the risk of skin cancer by minimizing exposure to harmful ultraviolet (UV) radiation from the sun. Encouraging protective measures such as wearing sunscreen, avoiding tanning beds, and wearing protective clothing are all steps to prevent skin cancer before it develops.

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.
The clinic nurse is caring for a patient whose grandmother and sister have both had breast cancer. She requested a screening test to determine her risk of developing breast cancer and it has come back positive. The patient asks you what she can do to help prevent breast cancer from occurring. What would be your best response?
- A. Research has shown that eating a healthy diet can provide all the protection you need against breast cancer.
- B. Research has shown that taking the drug tamoxifen can reduce your chance of breast cancer.
- C. Research has shown that exercising at least 30 minutes every day can reduce your chance of breast cancer.
- D. Research has shown that there is little you can do to reduce your risk of breast cancer if you have a genetic predisposition.
Correct Answer: B
Rationale: Tamoxifen is a selective estrogen receptor modulator (SERM) that has been shown to significantly reduce the risk of developing breast cancer in women who are at high risk, particularly those with a family history of the disease or a positive genetic test for BRCA mutations. Large-scale studies have demonstrated that tamoxifen can reduce the incidence of breast cancer by up to 50% in high-risk women. It works by blocking estrogen receptors in breast tissue, which helps prevent the development of estrogen receptor-positive breast cancers.
A home health nurse is caring for a patient with multiple myeloma. Which of the following interventions should the nurse prioritize when addressing the patients severe bone pain?
- A. Implementing distraction techniques
- B. Educating the patient about the effective use of hot and cold packs
- C. Teaching the patient to use NSAIDs effectively
- D. Helping the patient manage the opioid analgesic regimen
Correct Answer: D
Rationale: Multiple myeloma causes severe bone pain due to the proliferation of malignant plasma cells in the bone marrow, leading to osteolytic lesions and bone destruction. Opioid analgesics are often required to manage this level of pain effectively, especially in cases where the pain is severe and chronic. The nurse's priority should be helping the patient manage their opioid regimen, ensuring they understand proper dosing, side effects, and safe use of the medication. Opioids are generally necessary in such cases because they provide stronger pain relief compared to other types of analgesics, such as NSAIDs or non-opioid medications.
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.
The nurse has taught a client with cancer ways to prevent infection. What statement by the client indicates that more teaching is needed?
- A. I should take my temperature daily and when I don't feel well.
- B. I will discard perishable liquids after sitting out for over an hour.
- C. I won't let anyone share any of my personal toiletries.
- D. It's alright for me to keep my pets and change the litter box.
Correct Answer: D
Rationale: Clients with cancer, especially those undergoing chemotherapy or other immunosuppressive treatments, are at increased risk for infections due to a weakened immune system. Changing a litter box exposes the client to pathogens such as Toxoplasma gondii and other harmful bacteria or parasites found in cat feces, which could lead to serious infections. It is recommended that immunocompromised individuals avoid activities like changing litter boxes to reduce their risk of exposure to infectious agents. A family member or caregiver should handle this task to protect the client.
