DSM-5 requires at least 5 of 9 specified symptoms present for a minimum of 2 weeks, with at least one being depressed mood or anhedonia.
Question 4: A PMHNP documents 'loosening of associations' in a patient. This thought process abnormality means:
- The patient shifts topic in response to sound rather than meaning
- The patient's thinking shifts between topics with tenuous connections (Correct answer)

The SCID is a semi-structured diagnostic interview conducted by trained clinicians and is considered the gold standard for establishing DSM diagnoses.
Question 6: A PMHNP suspects factitious disorder in a patient who fabricates symptoms. How does factitious disorder differ from malingering?
- Factitious disorder has external incentives; malingering does not
- Malingering has external incentives; factitious disorder is driven by psychological need to assume the sick role (Correct answer)
- They are the same disorder with different names
- Factitious disorder involves unconscious symptom production
Correct answer: Malingering has external incentives; factitious disorder is driven by psychological need to assume the sick role
In factitious disorder, symptom falsification is motivated by a psychological need to assume the sick role, with no external gains; malingering involves intentional feigning for external rewards.
