Final answer:
Primary data in health research, such as that gathered by a nurse, comes from first hand sources including interviews, observations, and experiments, which provides direct and original data related to the study.
Step-by-step explanation:
If a nurse is obtaining primary data, the information comes from direct sources such as interviews, observations, and experiments. This data is collected first hand and is original to the researcher’s study. For instance, a nurse might conduct in-depth interviews with patients or other healthcare professionals, observe patient behaviors and responses in a clinical setting, or conduct experiments to gather data. These activities provide valuable insights that are directly relevant to the research question at hand. Quantitative data may also be gathered if the research requires numerical information such as vital signs, medication dosages, or the number of patients with a particular condition.
