No. Even if an RN has completed the education approved by Council to become authorized to prescribe, their practice environment may not allow for it. This may be determined by law (for example, the Public Hospitals Act prevents RNs from ordering treatments for hospital clients) or by employer preferences and requirements.
Employers are responsible for determining the roles and responsibilities of their employees, including determining whether nurses can perform certain activities and procedures in the practice setting. RNs are expected to consult with their employers to confirm that prescribing is permitted in the practice setting.
