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.

Correct Answer: D

Rationale: Multiple myeloma is a type of cancer that involves the malignant proliferation of plasma cells, which are a type of white blood cell that produces antibodies. In multiple myeloma, these abnormal plasma cells accumulate in the bone marrow, where they interfere with the production of normal blood cells and lead to the formation of tumors in the bones. This can cause bone pain, fractures, anemia, and impaired immune function. The excessive production of abnormal antibodies can also result in kidney damage and other systemic complications.

Correct Answer: D

Rationale: Chemotherapeutic agents can be hazardous to healthcare workers if they are exposed to the drugs during preparation or administration. One of the primary risks is inhalation, where small particles or aerosols of the drug can become airborne and be inhaled, potentially causing harm to the nurse. Protective gear such as gloves and a gown, as well as masks or respirators in some cases, helps prevent this type of exposure.

Correct Answer: C

Rationale: Primary prevention involves actions taken to reduce the risk of developing cancer by preventing exposure to known risk factors or promoting healthy behaviors. Teaching patients to wear sunscreen is an example of primary prevention because it aims to reduce the risk of skin cancer by minimizing exposure to harmful ultraviolet (UV) radiation from the sun. Encouraging protective measures such as wearing sunscreen, avoiding tanning beds, and wearing protective clothing are all steps to prevent skin cancer before it develops.

Correct Answer: A

Rationale: Epoetin alfa is a medication used to treat anemia, particularly anemia related to chemotherapy or chronic kidney disease. It stimulates the bone marrow to produce more red blood cells, which increases the hemoglobin level. Monitoring hemoglobin is the best way to assess the effectiveness of epoetin alfa, as an increase in hemoglobin indicates that the body is producing more red blood cells and the anemia is improving.
