ATI Oncology Quiz

Correct Answer: C

Rationale: Chemotherapy drugs are typically administered systemically, meaning they circulate throughout the body via the bloodstream. This allows them to target cancer cells that may have spread beyond the original tumor site, making chemotherapy an effective treatment for cancers that are metastatic (have spread to other parts of the body). However, because chemotherapy is not selective, it can also affect healthy cells that divide rapidly, leading to a range of side effects.

Correct Answer: B

Rationale: An increased lymphocyte count (lymphocytosis) is always present in patients with CLL.

Correct Answer: D

Rationale: In the Ann Arbor staging system for lymphomas, Stage 3 indicates that the disease has spread beyond the initial lymph node region to involve lymph nodes on both sides of the diaphragm (i.e., the areas above and below the diaphragm). This includes lymphatic involvement in both the thoracic and abdominal regions, signifying a more advanced disease state.

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: D

Rationale: In clients undergoing chemotherapy, the immune system is often compromised due to the effects of treatment, making them more susceptible to infections. A fever over 100.4�F (38�C) is considered a critical sign of infection in these patients and requires immediate medical evaluation. Fever may indicate the presence of an infection that could escalate quickly in immunocompromised individuals, so it is vital for patients to recognize this symptom and seek prompt medical attention.
