A 29-year-old single woman presents to the PMHNP for evaluation of a chief complaint of fatigue. She states she has been feeling "tired" and "empty" for the past 4 years. She sleeps up to 11 hours a day and is still tired. She has trouble concentrating and has difficulty making decisions. She has gained 10 pounds over the past 2 years due to overeating and little physical activity. She reports no suicidal ideation or manic symptoms, and no delusions or hallucinations. What is the most likely diagnosis?
Major depressive disorder
Generalized anxiety disorder
Persistent depressive disorder (Dysthymia)
Cyclothymic disorder
The Correct Answer is C
Choice A reason: Major depressive disorder typically involves discrete episodes lasting at least 2 weeks with more acute severity. This patient’s 4-year chronic course suggests a different diagnosis.
Choice B reason: Generalized anxiety disorder is characterized by excessive worry rather than chronic low mood, fatigue, and anhedonia.
Choice C reason: Persistent depressive disorder (dysthymia) involves chronic depressive symptoms lasting at least 2 years in adults. The patient’s long-term low mood, fatigue, hypersomnia, poor concentration, and weight changes are consistent with dysthymia.
Choice D reason: Cyclothymic disorder involves fluctuating hypomanic and depressive symptoms; this patient has no hypomanic features.

Correct Answer is B
Explanation
Choice A reason: Bird’s safety triangle focuses on accident statistics and incident ratios, not systemic safety culture.
Choice B reason: Reason’s Swiss Cheese model illustrates that errors occur when multiple system defenses fail, emphasizing a culture of safety that examines latent failures and prevents blame, which aligns with the Just Culture approach.
Choice C reason: Heinrich’s domino model attributes accidents primarily to individual error, not systemic factors, and is less aligned with Just Culture principles.
Choice D reason: Rasmussen’s drift into failure model emphasizes gradual erosion of safety through organizational drift, which is related to but does not define the Just Culture model.
Correct Answer is D
Explanation
Choice A reason: Sharing confidential information without the patient’s consent violates privacy and HIPAA guidelines.
Choice B reason: While verifying identity is good practice, the main issue is maintaining confidentiality; the mother’s access is limited unless the patient consents.
Choice C reason: Giving vague answers may still reveal sensitive information and is not consistent with ethical practice.
Choice D reason: The PMHNP must respect the patient’s confidentiality because the 17-year-old consented to private discussions, so treatment details, including diagnoses, cannot be shared without consent.
