Cancer Development (Concepts for Interprofessional Collaborative Care College Test Bank)
MULTIPLE CHOICE
1. The student nurse learning about cellular regulation understands that which process occurs during the S
phase of the cell cycle?
a. Actual division (mitosis)
b. Doubling of DNA
c. Growing extra membrane
d. No reproductive activity
ANS: B
During the S phase, the cell must double its DNA content through DNA synthesis. Actual division, or mitosis,
occurs during the M phase. Growing extra membrane occurs in the G1 phase. During the G0 phase, the cell is
working but is not involved in any reproductive activity.
2. A student nurse asks the nursing instructor what apoptosis means. What response by the instructor is best?
a. Growth by cells enlarging
b. Having the normal number of chromosomes
c. Inhibition of cell growth
d. Programmed cell death
ANS: D
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 gr

3. The nursing instructor explains the difference between normal cells and benign tumor cells. What
information does the instructor provide about these cells?
a. Benign tumors grow through invasion of other tissue.
b. Benign tumors have lost their cellular regulation from contact inhibition.
c. Growing in the wrong place or time is typical of benign tumors.
d. The loss of characteristics of the parent cells is called anaplasia.
ANS: C
Benign tumors are basically normal cells growing in the wrong place or at the wrong time. Benign cells grow
through hyperplasia, not invasion. Benign tumor cells retain contact inhibition. Anaplasia is a characteristic of
cancer cells.
4. 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?
a. Artificial fibronectin infusion to maintain tight adhesion of cells
b. Chromosome repair kit to halt rapid division of cancer cells
c. Synthetic enzyme transfusion to allow rapid cellular migration
d. Telomerase therapy to maintain chromosomal immortality
