When involved in phase III drug evaluation studies, what responsibilities would the nurse have?

Choice A rationaleWorking with animals is typically done in preclinical trials before phase I studies in humans and is not part of phase III drug evaluation studies.Choice B rationaleConducting research to determine the effectiveness of the drug is part of phase II studies. Phase III studies focus more on confirming effectiveness, monitoring side effects, and comparing it to commonly used treatments.Choice C rationaleMonitoring and observing patients closely for adverse effects is a key responsibility in phase III drug evaluation studies. These studies involve a larger patient population to gather comprehensive safety and efficacy data.Choice D rationaleChoosing appropriate patients to be involved in the study is primarily the responsibility of researchers and clinicians during the earlier phases of drug development, such as phase I and phase II studies.
