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.

Nurse Maria is preparing a care plan for a client receiving external radiation therapy. Which of the following interventions should be included?
- A. Use heating pads on the treated area
- B. Wear loose, soft clothing over the treated area
- C. Expose the treated area to sunlight
- D. Apply ice packs to the treated area
Correct Answer: B
Rationale: Radiation therapy can cause skin irritation, dryness, and sensitivity in the treated area. Wearing loose, soft clothing helps minimize friction and pressure on the skin, reducing irritation and promoting comfort. The skin in the treated area is often more sensitive and vulnerable to damage, so this intervention helps protect the skin while maintaining the client's comfort during the course of treatment.
A patient admitted with cancer asks the nurse about the difference between chemotherapy and radiation therapy. Which of the following responses by the nurse indicates a need for further teaching?
- A. Chemotherapy kills cancer cells
- B. Radiation therapy can be internal or external
- C. Radiation therapy is often external
- D. Chemotherapy is more likely to kill normal cells
Correct Answer: D
Rationale: While chemotherapy does affect normal, healthy cells-particularly those that divide rapidly-it is not "more likely" to kill normal cells compared to cancer cells. Chemotherapy targets rapidly dividing cells, which includes both cancer cells and some normal cells (like those in hair follicles, the gastrointestinal tract, and bone marrow). However, its primary goal is to kill cancer cells, and its effects on normal cells are a side effect, not the main function. Therefore, the statement that chemotherapy is "more likely" to kill normal cells is inaccurate and indicates a need for further teaching.
A client is receiving chemotherapy through a peripheral IV line. What action by the nurse is most important?
- A. Assessing the IV site and blood return every hour.
- B. Educating the client on side effects.
- C. Monitoring the client for nausea.
- D. Providing warm packs for comfort.
Correct Answer: A
Rationale: Chemotherapy drugs are often vesicants, meaning they can cause severe tissue damage if they leak (extravasate) outside of the vein. When chemotherapy is administered through a peripheral IV line, it is crucial for the nurse to frequently assess the IV site for signs of complications such as redness, swelling, or pain, which could indicate extravasation. Checking for blood return ensures the IV catheter is still in the vein and functioning properly. Preventing tissue damage from chemotherapy extravasation is a top priority, and frequent monitoring helps ensure the infusion is proceeding safely.
A 35-year-old male is admitted to the hospital complaining of severe headaches, vomiting, and testicular pain. His blood work shows reduced numbers of platelets, leukocytes, and erythrocytes, with a high proportion of immature cells. The nurse caring for this patient suspects a diagnosis of what?
- A. AML
- B. CML
- C. MDS
- D. ALL
Correct Answer: D
Rationale: Acute Lymphocytic Leukemia (ALL) is a type of cancer where immature lymphocytes (a type of white blood cell) proliferate uncontrollably in the bone marrow. This leads to a reduction in the production of platelets, leukocytes, and erythrocytes, causing symptoms such as fatigue, anemia, bleeding tendencies, and increased susceptibility to infection. In ALL, leukemic cell infiltration into other organs is common, which can manifest as severe headaches (due to central nervous system involvement), vomiting, and testicular pain (due to infiltration of leukemic cells into the testes). These are hallmark signs of ALL, especially in younger patients.
The nurse is caring for a client who is at risk for tumor lysis syndrome. Which laboratory value requires the nurse to intervene?
- A. Decreased blood urea nitrogen (BUN)
- B. Increased serum calcium
- C. Increased creatinine level
- D. Increased blood glucose level
Correct Answer: C
Rationale: Tumor lysis syndrome (TLS) is a potentially life-threatening condition that occurs when large numbers of cancer cells die rapidly, releasing their contents into the bloodstream. This can overwhelm the kidneys and lead to acute kidney injury. Creatinine is a waste product filtered out of the blood by the kidneys, and an elevated creatinine level is a sign of kidney dysfunction or damage. In TLS, increased creatinine levels indicate that the kidneys are struggling to filter out the excess waste products from cell breakdown, requiring immediate intervention to prevent further complications, such as acute renal failure.
