Diagnosis and Treatment Framework
PMHNP board questions frequently test whether you can distinguish similar presentations and then implement a coherent management sequence.
Differential Precision Priorities
- Rule out substance-induced and medical etiologies when relevant.
- Evaluate longitudinal course, not single-visit snapshots.
- Use functional impairment and risk burden to guide urgency.
Treatment Design Checklist
- Confirm primary diagnosis and key differentials.
- Select initial intervention based on severity and risk.
- Define target symptoms and timeframe.
- Set side-effect and safety monitoring checkpoints.
- Reevaluate and adjust using objective outcomes.
