Question 1
Weighing everything Marcus has described, which provisional diagnosis is best supported, and on what grounds?
▸Show the answer — and why each of the other three is wrong
- A — correct
- The picture fits adjustment disorder cleanly. The symptoms started after an identifiable stressor (the new schedule and the divorce), well within the three-month window, and they are clearly tied to it. He still enjoys soccer and friends and holds hope for the future, and he had no pervasive low mood before the separation. His distress at 7/10, sleep and appetite change, and irritability affecting his parenting and flagged at work push it past a normative reaction, and 'mixed anxiety and depressed mood' captures both the 'wound up' feeling and the low mood on handoff days.
- B — incorrect
- This is the tempting near-miss, because the sleep, appetite, and mood symptoms overlap a depressive episode. But he denies anhedonia and hopelessness, his interests are intact, and his mood is not pervasively depressed for two straight weeks; it swings with the conflict and transitions. The symptoms are stressor-linked and fluctuating, which points away from a primary major depressive episode.
- C — incorrect
- This is genuinely close, because it is the right disorder and his anxiety is prominent, so the anxiety-only subtype is tempting. But he also reports clearly depressed mood that is worst on handoff days alongside the 'wound up' feeling. When both are present, 'mixed anxiety and depressed mood' is the accurate subtype, so C is the right disorder with the wrong specifier.
- D — incorrect
- This is a real diagnostic tension, not a throwaway: his reaction is understandable and he is still working, coaching, and seeing friends, which invites reading it as normal stress. But the threshold turns on severity, and his distress and impairment, 7/10 distress, disrupted sleep and appetite, irritability affecting his parenting, and a supervisor noticing at work, exceed what is expectable and cross into a diagnosable adjustment disorder.
