The pharmacology instructor explains to the nursing students that drugs will have the least effect on the cell during what phase of the cell cycle?
A) G0 phase
B) G1 phase
C) S phase
D) G2 phase
A
Feedback:
During the G0 phase, or resting phase, the cell is stable. It is not making any proteins associated with cell division and is basically dormant in terms of reproduction. These cells are functioning to do whatever they are supposed to do. Most drugs, particularly chemotherapy for cancer, work on active cells so cells that are resting are less susceptible to chemical action. The other options are active phases when drugs will be most effective.
