Which of the following statements by the oncology nurse displays understanding about antineoplastic medications?
- A. Chemotherapy is not going to spread throughout the body
- B. Chemotherapy affects the immune system
- C. Chemotherapy is specific to cancer cells only
- D. Chemotherapy makes the patient radioactive
Correct Answer: B
Rationale: Chemotherapy targets rapidly dividing cells, which include both cancerous and healthy cells, such as those in the bone marrow, hair follicles, and the lining of the digestive tract. Since the bone marrow produces immune cells (white blood cells), chemotherapy can weaken the immune system by reducing the body's ability to produce these cells, making patients more susceptible to infections. This is why close monitoring and supportive measures to protect immune function are important during chemotherapy treatment.

A patient with a myelodysplastic syndrome is being treated on the medical unit. What assessment finding should prompt the nurse to contact the patients primary care provider?
- A. The patient is experiencing a frontal lobe headache.
- B. The patient has an episode of urinary incontinence.
- C. The patient has an oral temperature of 37.5C (99.5F).
- D. The patients SpO2 is 91% on room air.
Correct Answer: C
Rationale: Patients with myelodysplastic syndrome (MDS) have a dysfunctional bone marrow that leads to ineffective blood cell production, including white blood cells, which are crucial for fighting infections. As a result, they are at high risk for infections. Even a slight elevation in temperature, such as 37.5°C (99.5°F), could be an early sign of infection in an immunocompromised patient. Early detection and treatment of infections are critical in MDS patients, as infections can quickly become severe or life-threatening due to their compromised immune system.
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.
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.
Nurse Joy is caring for a client with an internal radiation implant. When caring for the client, the nurse should observe which of the following principles?
- A. Limit the time with the client to 1 hour per shift
- B. Do not allow pregnant women into the client's room
- C. Remove the dosimeter badge when entering the client's room
- D. Individuals younger than 16 years old may be allowed to go in the room as long as they are 6 feet away from the client
Correct Answer: B
Rationale: Clients with internal radiation implants (also known as brachytherapy) emit a small amount of radiation, which can pose a risk to others. Pregnant women are particularly vulnerable to the harmful effects of radiation because it can affect both the mother and the developing fetus. Radiation exposure can lead to birth defects, miscarriage, or other developmental issues, so pregnant women should avoid any exposure by not entering the client's room.
