,Q1. A patient with treatment-resistant depression has failed two adequate trials of SSRIs
and one trial of venlafaxine. The patient also has comorbid generalized anxiety disorder.
Which augmentation strategy is most supported by current evidence for both depressive and
anxiety symptoms?
A. Add aripiprazole 2-5 mg daily
B. Switch to phenelzine 45 mg daily
C. Add buspirone 30 mg daily
D. Add quetiapine XR 150 mg at bedtime
Correct Answer: A. Add aripiprazole 2-5 mg daily
Rationale: Aripiprazole is FDA-approved for augmentation in major depressive disorder and has
evidence for anxiety reduction. Phenelzine is effective but requires dietary restrictions and is not
first-line augmentation. Buspirone has weak evidence for augmentation. Quetiapine XR is
approved but has more metabolic side effects; aripiprazole has a more favorable profile.
Why Wrong:
B - Phenelzine is a MAOI requiring strict tyramine restrictions and is not typically used for
augmentation after only three failed trials.
C - Buspirone has limited evidence as an augmentation agent for depression and is more
effective for generalized anxiety as monotherapy.
D - Quetiapine XR is effective but associated with significant weight gain and metabolic
syndrome, making it less preferred than aripiprazole.

Q2. A patient on lithium therapy for bipolar I disorder is admitted with confusion, ataxia,
and coarse tremors. Serum lithium level is 2.1 mEq/L. Which of the following best explains
the mechanism of lithium toxicity at this level?
A. Lithium displaces sodium at voltage-gated sodium channels, causing neuronal
hyperexcitability
B. Lithium inhibits adenylyl cyclase excessively, disrupting cAMP-mediated signaling in
renal and neural tissues
C. Lithium competes with magnesium at NMDA receptors, leading to excitotoxicity
D. Lithium increases serotonin synthesis, resulting in serotonin syndrome
Correct Answer: B. Lithium inhibits adenylyl cyclase excessively, disrupting
cAMP-mediated signaling in renal and neural tissues
Rationale: Lithium's therapeutic action involves inhibition of inositol monophosphatase and
modulation of G proteins, but at toxic levels, excessive inhibition of adenylyl cyclase disrupts
multiple signaling pathways, leading to neurological and renal toxicity. Lithium does not
primarily act on sodium channels or NMDA receptors. Serotonin syndrome is not typical.
Why Wrong:
A - Lithium does not significantly interact with voltage-gated sodium channels; that is a
mechanism of local anesthetics and some anticonvulsants.
C - Lithium does not compete with magnesium at NMDA receptors; it affects inositol

, phosphate and G protein signaling.
D - Lithium may enhance serotonin function but does not cause serotonin syndrome; toxicity
is distinct.
