- Acute stress disorder

- Alprazolam
- Sertraline (Correct answer)
- Olanzapine
- Propranolol

Sertraline and paroxetine are the only FDA-approved medications for PTSD; benzodiazepines are not recommended due to risk of dependence and potential worsening of PTSD.

Correct answer: 2 weeks
DSM-5 requires symptoms of major depressive disorder to be present for at least 2 weeks and represent a change from previous functioning for the diagnosis.
