Instructions & Strategy for WGU D455 Objective Assessment
The WGU D455 Objective Assessment (OA) evaluates your readiness to transition into advanced professional
nursing roles. Success on this assessment relies heavily on applying theoretical concepts to situational clinical
scenarios rather than mere rote memorization.
💡 Key Test-Taking Rules:
Prioritization: Remember Maslow's Hierarchy of Needs and ABCs (Airway, Breathing, Circulation).
Delegation: Unlicensed Assistive Personnel (UAP) take standard, predictable tasks. Licensed Practical
Nurses (LPNs) care for stable patients with predictable outcomes. RNs handle Assessment, Teaching, and
Evaluation (E-A-T).
Legal Standards: Always respect autonomy and informed consent; scope of practice is dictated by
individual State Nurse Practice Acts.
