Which rationales are most appropriate for the nurse to use when responding to this client's question? 1. During the time of exclusivity, there is little competition, resulting in higher prices. 2. During the time of exclusivity, there are generic versions of the drug, but the pharmacist has the right to sell only the brand-name drug. 3. Once the time of exclusivity is over, other drug companies will be able to market generic drugs for less than the brand-name drug. 4.
