Substitutive Application describes APN and physician functions that are:

• A. APNs replace doctors in all settings
• B. APNs do not work with physicians
• C. Nurses assistant roles
• D. Similar and equal - Primary Care

Answer: (D)

Substitutive application means APN and physician functions are similar and equal in primary care. In this model, an advanced practice nurse delivers care that a physician would typically provide—history and physical examination, diagnosing, ordering and interpreting tests, creating and implementing treatment plans, and prescribing medications—within the APN’s scope and in collaboration with physicians as appropriate. The key idea is substitution: APNs can stand in for physicians in many primary care situations, delivering comparable quality and access to care, rather than performing a completely separate, non-overlapping role. This differs from notions that APNs replace doctors in all settings or that nurses’ roles are simply assistants, or that APNs don’t work with physicians.
