Rationale: In clients experiencing neutropenia, particularly due to chemotherapy, the immune system is significantly compromised, increasing the risk of infections. Hand hygiene is one of the most effective methods for preventing the spread of pathogens that can lead to infections. Teaching both the client and their family about the importance of frequent and proper handwashing helps create a safer environment and reduces the risk of infections, which can be critical in neutropenic patients.

Correct Answer: B

Rationale: Epoetin alfa (Epogen) is a synthetic form of erythropoietin, a hormone that stimulates the production of red blood cells in the bone marrow. Chemotherapy often leads to anemia due to its effects on rapidly dividing cells, including those in the bone marrow responsible for red blood cell production. By administering epoetin alfa, the healthcare provider aims to increase the red blood cell count and improve hemoglobin levels, thereby alleviating symptoms associated with anemia, such as fatigue and weakness.

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.
