Chapter 21 Questions
Question 1 of 5
A client is in the oncology clinic for a first visit since being diagnosed with cancer. The nurse reads in the client's chart that the cancer is rated TIS, N0, M0. What does this indicate?
Correct Answer: D
Rationale: TIS stands for carcinoma in situ, N0 stands for no regional lymph node metastasis, and M0 stands for no distant metastasis.
Question 2 of 5
The nursing instructor explains the difference between normal cells and benign tumor cells. What information does the instructor provide about these cells?
Correct Answer: C
Rationale: Benign tumors are basically normal cells growing in the wrong place or at the wrong time. Benign cells grow through hyperplasia, not involution. Benign tumor cells retain contact inhibition. Anaplasia is a characteristic of cancer cells.
Question 3 of 5
A student nurse asks its nursing instructor what apoptosis means. What response by the instructor is best?
Correct Answer: D
Rationale: Apoptosis is programmed cell death. With this characteristic, organs and tissues function with cells that are at their peak of performance. Growth by cells enlarging is hyperplasia. Having the normal number of chromosomes is euploidy. Inhibition of cell growth is contact inhibition.
Question 4 of 5
A group of nursing students has entered a futuristic science contest in which they have developed a cure for cancer. Which treatment would most likely be the winning entry?
Correct Answer: A
Rationale: Cancer cells do not have sufficient fibronectin and so do not maintain tight adhesion with other cells. This is part of the mechanism of metastasis. Chromosome alterations in cancer cells (aneuploidy) consist of having too many, too few, or altered chromosome pairs, but this does not necessarily lead to rapid cellular division. Rapid cellular migration is part of metastasis. Immortality is a characteristic of cancer cells due to telomerase activity.
Question 5 of 5
A nurse is participating in primary prevention efforts directed against cancer. In which activities is this nurse most likely to engage? (Select all that apply.)
Correct Answer: B,C,E
Rationale: Primary prevention aims to prevent the occurrence of a disease or disorder, in this case cancer. Secondary prevention includes screening and early diagnosis. Primary prevention activities include teaching people about chemoprevention, providing approved vaccinations to prevent cancer, and teaching teens the dangers of tanning beds. Secondary prevention includes screening girls for cervical cancer and demonstrating breast self-examination methods.
