ATI Oncology Questions

Correct Answer: D

Rationale: Clients with cancer, especially those undergoing chemotherapy or other immunosuppressive treatments, are at increased risk for infections due to a weakened immune system. Changing a litter box exposes the client to pathogens such as Toxoplasma gondii and other harmful bacteria or parasites found in cat feces, which could lead to serious infections. It is recommended that immunocompromised individuals avoid activities like changing litter boxes to reduce their risk of exposure to infectious agents. A family member or caregiver should handle this task to protect the client.

Correct Answer: D

Rationale: When caring for a client with an internal cervical radiation implant, safety measures must be followed to protect both the client and healthcare personnel from radiation exposure. If the implant becomes dislodged and is found in the bed, the nurse's priority is to handle it safely using long-handled forceps, as direct contact with the implant could result in radiation exposure. The implant should be placed in a lead-lined container, which is specifically designed to shield against radiation, to prevent further contamination or exposure. After securing the implant, the nurse should notify the radiation safety officer or healthcare provider for further guidance.

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: B

Rationale: Contact inhibition is a regulatory mechanism that prevents cells from proliferating once they reach a certain density. Normally, when cells grow and touch each other (such as in a monolayer), they stop dividing, maintaining tissue integrity and structure. When contact inhibition is lacking, as in many cancerous cells, cells continue to grow and divide uncontrollably, leading to tumor formation. This loss of regulation is a hallmark of cancerous growth.

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.
