SECTION 1: SCIENTIFIC FOUNDATION & PSYCHOPHARMACOLOGY
Question 1
A 22-year-old patient recently diagnosed with bipolar disorder states, "I'm not crazy," and is refusing to
take his prescribed medication. Which type of factor is contributing to this patient's nonadherence?
A) Client factors
B) Clinician factors
C) Structural factors
D) Environmental factors
Correct Answer: A) Client factors
Rationale: Client factors include the patient's beliefs, attitudes, and understanding of their illness. The
patient's denial of the diagnosis and resistance to treatment reflects a client-level factor affecting
adherence. Clinician factors relate to the provider-patient relationship; structural factors involve access
to care; environmental factors include social support and living situation .
Question 2
A patient has been taking fluoxetine 40 mg/day for 6 weeks and reports no improvement in depressive
symptoms. What is the best next step?
A) Increase to 60 mg/day immediately
B) Add a second antidepressant
C) Switch to venlafaxine
D) Assess adherence and consider dose optimization within the therapeutic range
Correct Answer: D) Assess adherence and consider dose optimization within the therapeutic range
Rationale: Fluoxetine 40 mg is often subtherapeutic for some patients. The first step is to assess
adherence, then consider increasing to the maximum of 80 mg per day before switching to another
agent .
,Question 3
A patient is started on phenelzine (Nardil), a monoamine oxidase inhibitor (MAOI). Which dietary
instruction is most critical?
A) "Increase your intake of aged cheeses, cured meats, and red wine."
B) "Avoid tyramine-rich foods such as aged cheese, smoked fish, and fermented products."
C) "You may drink as much coffee as you like."
D) "Tyramine is safe; the old warnings no longer apply."
Correct Answer: B) "Avoid tyramine-rich foods such as aged cheese, smoked fish, and fermented
products."
Rationale: MAOIs block the breakdown of tyramine, which can cause a hypertensive crisis if tyramine-
rich foods are consumed. These include aged cheeses, cured or processed meats, fermented foods, red
wine, and some draft beers .
Question 4
The half-life of a medication is 12 hours. Approximately how many hours will it take for the drug to reach
steady state?
A) 24 hours
B) 48 hours
C) 60 hours
D) 72 hours
Correct Answer: C) 60 hours
Rationale: Steady state is generally achieved after 5–6 half-lives. 5 × 12 = 60 hours. After this time, drug
accumulation and elimination become balanced, and serum levels remain relatively constant .
Question 5
A 68-year-old patient with Alzheimer's disease is started on donepezil. Which adverse effect is most
concerning in this age group?
A) Diarrhea
B) Nightmares
C) Syncope due to bradycardia
D) Weight gain
Correct Answer: C) Syncope due to bradycardia
,Rationale: Cholinesterase inhibitors (donepezil, rivastigmine, galantamine) can cause symptomatic
bradycardia and syncope, especially in older adults. This is the most concerning adverse effect due to the
risk of falls and cardiovascular events .
Question 6
A patient with bipolar I disorder stabilized on lithium presents with tremor, nausea, and confusion. Labs
show: sodium 130 mEq/L, lithium level 1.8 mEq/L. What is the most appropriate next action?
A) Increase lithium dose
B) Hold lithium and give IV fluids
C) Add haloperidol
D) Continue same dose and recheck in 2 days
Correct Answer: B) Hold lithium and give IV fluids
Rationale: Lithium toxicity (level ≥1.5 mEq/L) with hyponatremia requires holding lithium and correcting
sodium and volume status. Lithium toxicity can present with tremor, nausea, confusion, and in severe
cases, seizures and coma .
Question 7
Which medication is associated with the highest risk of weight gain among the following?
A) Fluoxetine
B) Sertraline
C) Paroxetine
D) Escitalopram
Correct Answer: C) Paroxetine
Rationale: Paroxetine (Paxil) is associated with a higher risk of weight gain compared to other SSRIs
(fluoxetine, sertraline, escitalopram). It also has significant anticholinergic effects and a shorter half-life,
leading to withdrawal symptoms upon discontinuation.
Question 8
A patient with treatment-resistant depression is started on aripiprazole as an adjunct to their SSRI. What
is the most important monitoring parameter?
A) Liver function tests
B) Fasting blood glucose and lipid panel
C) Complete blood count
D) Thyroid function tests
Correct Answer: B) Fasting blood glucose and lipid panel
, Rationale: Atypical antipsychotics (including aripiprazole) are associated with metabolic side effects,
including hyperglycemia, dyslipidemia, and weight gain. Baseline and periodic monitoring of fasting
blood glucose and lipid panel is essential.
SECTION 2: ADVANCED PRACTICE SKILLS & ASSESSMENT
Question 9
A 72-year-old patient scores 17 on the Mini-Mental State Examination (MMSE). This indicates:
A) Normal cognitive function for age
B) Mild cognitive impairment
C) Moderate cognitive impairment
D) Severe dementia
Correct Answer: C) Moderate cognitive impairment
Rationale: MMSE scores range from 0–30. Scores of 20–24 suggest mild dementia, 13–20 moderate
dementia, and <12 severe dementia. A score of 17 is consistent with moderate cognitive impairment .
Question 10
Which screening tool is most appropriate for assessing mild cognitive dysfunction in an older adult?
A) Mini-Mental State Examination (MMSE)
B) Geriatric Depression Scale (GDS)
C) Montreal Cognitive Assessment (MoCA)
D) Beck Depression Inventory (BDI)
Correct Answer: C) Montreal Cognitive Assessment (MoCA)
Rationale: The Montreal Cognitive Assessment (MoCA) is a brief, 30-point test used to screen for mild
cognitive dysfunction. It assesses multiple cognitive domains including memory, attention, language,
visuospatial skills, and executive function .
Question 11
During a mental status exam, a patient says, "The CIA is controlling my thoughts with satellites." This is
an example of:
A) Illusion
B) Idea of reference
C) Delusion of persecution
D) Thought insertion
Correct Answer: C) Delusion of persecution
