Step-by-step explanation:
The first step a nurse should complete when implementing an educational program about the importance of being physically active is c. Gain the learner's attention. Before diving into the content or helping the learner make connections with prior learning, it is crucial to ensure that the learner is engaged and interested in the information that will be presented.
