Family History Response Feedback: “The strongest established risk factor for BPD is a family history of BPD.” • Question 2 Which of the following medications are known as selective serotonin re-uptake inhibitors (SSRIs)? i. Nortriptyline ii. Citalopram iii. Duloxetine iv. Fluoxetine v. Venlafaxine • Question 3 Which disease state of a non-adherent patient is at greater risk for substance use, violence, and victimization as well as worse overall quality of life? Schizophrenia Response Feedback: “Moreover, non-adherent patients with schizophrenia are at greater risk for substance use, violence, and victimization as well as worse overall quality of life.” • Question 4 Patient is a 72-year-old male with a past medical history significant for atrial fibrillation and COPD with a new diagnosis of major depression disorder. Based on his comorbid conditions, what antidepressant would you recommend as first-line? Atomoxetine Response Feedback: (Options C & D are both TCA antidepressants and, based on the patient’s age and comorbid conditions, a TCA would likely result in more side effects, such as increased fall risk due to potential for orthostatic hypotension and anticholinergic-related side effects. In addition, patient has a history for cardiac abnormalities due to A. fib diagnosis - TCAs result in electrocardiographic changes in susceptible individuals, therefore, would likely avoid. Choice B is used more for ADHD purposes than as an antidepressant) Page numbers used: Page 39 for TCA side-effect profile • Question 5 Which of the following is an appropriate strategy for managing treatment- resistant depression? Use both SSRI and SNRI Response Feedback: “As is true for panic and the other anxiety disorders, the SSRIs and SNRIS are generally considered first-line agents for the treatment of GAD because of their favorable side effect profile….” • Question 12 The serotonin system is involved in many processes in psychiatry, including, most prominently, mood, sleep, and psychosis. Of the following neurons listed, from where is serotonin synthesized? Response Feedback: under serotonin subheading and figure 1-18 on page 16: Locus Coeruleus: Norepinephrine Nucleus basalis: cholinergic neurons Substantia Nigra: dopamine Ventral Tegmental area: dopamine • Question 13 Which of the following symptoms is NOT part of the diagnostic features for bipolar disorder?

He reported stopping the medication 1 day ago and is now experiencing extreme irritability and nervousness. He wishes to stop this medication due to side effects. What do you recommend? Response Feedback: under selective serotonin re-uptake inhibitors discontinuation syndrome subtitle: “The risk of such adverse events occurring seems to be inversely related to the half-life of the SSRI, with fluoxetine reported as having a significantly lower risk than paroxetine in two studies. For more severe discontinuation-related adverse events, re-institution of the SSRI and slow taper may be necessary to alleviate these symptoms.” • Question 15 It is appropriate to start lamotrigine in combination with another atypical antipsychotic in treatment of an acute manic episode in bipolar disorder. Response Feedback: “Lamotrigine has also been extensively studied in bipolar depression as well….” • Question 16 Which antiepileptic drugs should we avoid in pregnant women in the treatment of bipolar disorder? .

Attention, memory, and executive functions Response Feedback: “For schizophrenia, the primary target symptoms for antipsychotic agents fall into three categories: psychotic symptoms (e.g., hallucinations, delusions, disorganization); agitation (e.g., distractibility, affective liability, tension, increased motor activity); and negative symptoms (e.g. apathy, diminished affect, social withdrawal, poverty of speech.” AND “Although cognitive deficits are an important contributor to disability in schizophrenia, cognitive deficits usually are not considered a target for antipsychotic agents because they are not very responsible to current agents.” • Question 23 Of the following antipsychotic medications listed below, which one has a Black Box Warning for seizure, agranulocytosis, and seizures? Response Feedback: Box 7-5 * indicated clozapine-specific black box warnings • Question 24 Which neurotransmitter is considered the major inhibitory neurotransmitter? • Question 25 A 27-year-old female presents to your emergency room today with a rash that started about 1 week ago and has now spread to her whole body. She has a past medical history significant for type 2 diabetes, hypertension and bipolar disorder. The patient reports, “The only thing that is different is that I’ve been on this new medication for my bipolar for a few weeks.” Of the following medications, which one is likely to be causing this severe rash? • Question 26 Glia cells play a supportive role in the neuron. A few of the functions of the glial cells include providing nutrition, maintaining homeostasis, stabilizing synapses, and myelination axons. The glial cells are categorized as microglia or microglia. Of the microglia cells, which one plays a role in myelination axons, which may contribute to mood disorders if altered? • Question 27 Which of the following medications used for treatment of bipolar disorder may increase stroke risk among older patients, particularly those with dementia? Response Feedback: “Notably, pharmacovigilance studies suggest that atypical antipsychotics may increase stroke risk among older patients, particularly those with dementia, so use of SGA requires more caution in this group.” • Question 28 Which of the following receptors below would likely result in extra-pyramidal symptoms, tardive dyskinesia, and Hyperprolactinemia? Response Feedback: first generation antipsychotics all share the common property of D2 blockade, which can produce EPS, TD, and Hyperprolactinemia • Question 29 Which anticonvulsant below induces its own metabolism over time? • Question 30 K. B. is a 28-year-old male who was started on Venlafaxine 75 mg about 2 weeks ago and is now calling you asking how long it should take for this medication to begin to work. He is concerned his girlfriend will leave him if he doesn’t get better quickly. What is the appropriate amount of time to allot to see a therapeutic response?

Is the NMDA receptor an inotropic or metabotropic receptor? • Question 39 When initiating lithium, how long should you wait before checking a lithium level? What is the therapeutic goal level of lithium? • Question 40 Choose the appropriate pair regarding acetylcholine receptors. Response Feedback: “There are two classes of Ache receptors: muscarinic and nicotinic. While muscarinic receptors are G-protein-coupled, nicotinic receptors are ion channels, which allows for rapid influx of NA+ and Ca2+ into the post-synaptic neuron.” • Question 41 Patient is a 59-year-old male with a past medical history significant for bipolar disorder I, hypertension, and COPD. He calls your clinic today complaining of extreme fatigue and a new tremor in his hand. He reports starting lithium 600 mg at bedtime about 5 days ago and thinks that may be the cause. What is the appropriate next step for this patient? Response Feedback: “Other bothersome adverse effects” Patient is likely experiencing lithium toxicity and labs should be verified first before continuing with other treatments for the tremor. • Question 42 Choose the appropriate statement regarding lamotrigine dosing. Response Feedback: Carbamazepine induced metabolism of lamotrigine – increase dose of lamotrigine; Valproate may inhibit clearance of lamotrigine, so dose reduction of lamotrigine is needed • Question 43 Choose the correct option regarding the major classes of GABA receptors and the ions involved in inhibition of the neurotransmitter pathway Response Feedback: “GABAB receptors, akin to the metabotropic glutamate receptors, are G-protein-coupled receptors rather than ion channels. Activation of GABAB causes downstream changes in potassium (K+) and Ca+2 channels, largely via G-protein-mediated inhalation of camp.” • Question 44 A 25-year-old female comes into your clinic today informing you she is ready to have a baby and wishes to discontinue her birth control at this time. After reviewing her chart, you notice she has a history of bipolar disorder and was previously prescribed valproic acid by another doctor.
