If you cannot find your certification in the official database, what is your next step?

The appropriate action upon finding that your certification is not listed in the official database is to contact the nurse who taught your class. This step is correct because the instructor is likely to have specific knowledge about your certification process, including any issues that may have arisen during the documentation or submission of your certification information. They can provide guidance on the next steps to take, such as verification of your attendance, performance on the exam, or issuing of the certification.

While other options might seem helpful, they do not directly lead to obtaining clarity or a resolution regarding your certification. Retaking the certification exam may not be necessary if the issue is simply a record-keeping problem. Asking coworkers for assistance may not be productive, as they may not have the relevant information or authority to address your certification status. Inquiring at the pharmacy is unlikely to be beneficial since they do not manage training or certification processes for medication administration.
