Question No 9

An oncology nurse is caring for a client with newly diagnosed B-cell lymphoma. Extensive blood work has been drawn and sent to the lab. Results reveal an elevated antiapoptotic protein BCL-2 level.

A) The client's immune system is trying to kill the cancer cell by sending this protein to engulf it.

B) This is a good result. Normal cells undergo apoptosis if DNA is damaged in any way.

A) "As much as possible, try to eat organic foods."

B) "Regular vitamin supplements and a low-carbohydrate diet are beneficial."

C) "Try to minimize fat and maximize fiber when you're planning your meals."

D) "Eat enough fiber in your diet that you have bowel movement at least once daily."

Question No 14

A 40-year-old female has been diagnosed with hepatocellular carcinoma. When asked what causes this cancer, the physician looks at the history and responds, "I see in your history, you have had:
