ATI Oncology Quiz

Correct Answer: B

Rationale: Risk for infection is a high priority due to the patient's compromised immune system from AML.

Correct Answer: C

Rationale: Prophylactic surgery refers to the preventive removal of tissues or organs at high risk for developing cancer, even when no cancer is currently present. In this case, the patient has a positive breast tumor marking test and a significant family history of breast cancer, which places her at increased risk for developing the disease. A bilateral mastectomy is performed to significantly reduce this risk by removing both breasts, thereby preventing the potential future occurrence of breast cancer.

Correct Answer: D

Rationale: Chemotherapy drugs are designed to target and destroy rapidly dividing cells, which include cancer cells. Cancer cells often divide more quickly than normal cells, and chemotherapeutic agents exploit this characteristic to inhibit their growth and promote cell death. While chemotherapy can also affect other rapidly dividing normal cells (such as those in the bone marrow, gastrointestinal tract, and hair follicles), the primary goal is to target cancerous cells.

Correct Answer: B

Rationale: Doxorubicin (Adriamycin) is an anthracycline chemotherapy agent commonly used to treat various cancers, including breast cancer. One of the significant side effects associated with doxorubicin is cardiotoxicity, which can lead to serious complications such as heart failure and arrhythmias. The risk of cardiotoxicity is dose-dependent, meaning that higher cumulative doses increase the likelihood of cardiac damage. Therefore, it is essential for nurses to monitor cardiac function closely through assessments such as echocardiograms or monitoring for signs and symptoms of heart failure, such as shortness of breath, fatigue, and edema.

Correct Answer: A

Rationale: If oral anesthetics are used, the patient must be warned to chew with extreme care to avoid inadvertently biting the tongue or buccal mucosa.
