In understanding the growth fraction as it pertains to the success of chemotherapy, the nurse knows that the growth fraction is a ratio of
 
  1. the number of replicating cells to the number of active cells.
  2. the number of non-replicating cells to the active cells.
  3. the number of replicating cells to the number of resting cells.
  4. The number of non-replicating cells to the number of resting cells.

Question 2

In understanding the difference between normal cells and cancer cells, the nurse knows that cancer is the result of
 
  1. cell division occurring extensively in normal cells.
  2. cell division occurring via controlled cell division.
  3. suppressor genes stopping cell growth for cell division.
  4. suppressor genes continuing cell growth for cell division.

Answer to Question 1

Correct Answer: 3
Rationale 1: This is not the ratio as it relates to the growth fraction.
Rationale 2: This is not the ratio as it relates to the growth fraction.
Rationale 3: The growth fraction is a measure of the number of cells undergoing mitosis in a tissue. It is a ratio of the number of replicating cells to the number of resting cells.
Rationale 4: This is not the ratio as it relates to the growth fraction.

Answer to Question 2

Correct Answer: 3
Rationale 1: Extensive cell division does occur in normal cells.
Rationale 2: Cell division does occur via controlled cell division.
Rationale 3: Cancer is thought to result from damage to the suppressor genes controlling cell growth.
Rationale 4: Suppressor genes for cell growth must continue for cell division and replication.
