FOUNDATIONS (Weeks 5-8 Review)
Question 1: A PMHNP is conducting an initial
psychiatric evaluation. Which of the following best
describes the primary purpose of the "differential
diagnosis" process?
A) To confirm the patient's self-reported diagnosis
B) To develop a working list of potential disorders
that could explain the patient's symptoms
2
,C) To rule out all medical causes of psychiatric
symptoms before considering any mental health
diagnosis
D) To assign a single diagnosis that will guide all
future treatment decisions
Correct Answer: B
Rationale: Differential diagnosis involves
developing a working hypothesis or list of potential
disorders that could account for the presenting
symptoms. This list is prioritized, and each potential
diagnosis is systematically ruled in or out based on
diagnostic criteria, history, and assessment findings .
Question 2: According to the DSM-5-TR, which of
the following must be ruled out before assigning
most psychiatric diagnoses?
A) Childhood trauma history

, B) Substance use and other medical conditions
C) Family history of mental illness

Correct Answer: B
Rationale: The DSM-5-TR requires clinicians to rule
out substance/medication-induced conditions and
other medical conditions as the primary cause of
symptoms before assigning a primary psychiatric
diagnosis .
Question 3: A holistic approach to psychiatric
assessment recognizes that mental health is
influenced by:
A) Only biological and genetic factors
