I think each job differs depending on what you are researching. Some are based in academic institutions, others are based in clinical environments.
As a clinical research nurse I used to:
- prepare patients to enter clinical trials (ensuring informed consent)
- monitor and follow-up patients according to the research protocols
- prepare ethics proposals
- prepare research proposals
- negotiate with pharmaceutical companies on set up and contracts for research studies
- Liaise with companies on on-going clinical trials
- negotiate with hospital administration
- Making sure all research complies with GCP guidelines
- Making sure all research WHO codes of conduct
