The NR 547 Midterm Examination is a summative assessment developed for the Differential Diagnosis in Psychiatric-Mental Health Across the Lifespan Practicum, a core course in the Psychiatric-Mental Health Nurse Practitioner (PMHNP) curriculum at Chamberlain University (College of Nursing). This high-stakes midterm examination is designed to evaluate the student's mastery of the differential diagnosis formulation process, the application of DSM-5-TR diagnostic criteria, and the integration of lifespan-specific considerations within psychiatric-mental health assessment. It serves as a critical indicator of readiness to advance in the PMHNP practicum sequence and to enter supervised clinical training.
