1. DNA to mimic CD4 cells.
2. T4 helper cells to RNA.
3. RNA to DNA.
4. gp 120 to gp 41.

Reverse transcriptase reverses the normal process and allows the RNA to be transcribed to the DNA rather than the DNA to be transcribed to the RNA.

The physician has written an order for a client for a new antihypertensive drug. Why is it important that the nurse have an understanding of the drug's prototype?
1. Knowledge of the prototype allows the nurse to surmise important information about an unfamiliar drug in the same class. 2. If the nurse knows the actions and adverse effects of the prototype drug, this information can be relevant to use of the unfamiliar drug. 3. The safety profile for the prototype is the same as the safety profile for the unfamiliar drug. 4. Knowledge of the prototype drug's therapeutic or pharmacologic classification can offer useful information about the unfamiliar drug. 5. Traditional prototype drugs are often older and infrequently prescribed, and the information about them should not be used.
