The nurse is discussing medications that affect cells only at specific times in the cell cycle. What information should the nurse include?
1. "Cells cycle very quickly, so it is important to keep the client's blood level of medications stable."
2. "The length of the cell cycle varies among different types of body cells."
3. "The length of the cell cycle is typically at least two hours, so this medication has the opportunity to work for a long period."
4. "All the cells in a tissue have synchronized cell cycles."

Rationale 1: The cell cycle rate is variable.
