1
, Antidepressants & Neurotransmitters
1. MAOIs (monoamine oxidase inhibitors) affect which neurotransmitters?
•
• Correct Answer: A. Serotonin, Dopamine, Norepinephrine
• Rationale: Monoamine oxidase (MAO) is the enzyme responsible for breaking down
monoamine neurotransmitters. By inhibiting this enzyme, MAOIs increase the synaptic
availability of all three primary monoamines: serotonin, dopamine, and
norepinephrine.
•
2. Which of the following is considered first line treatment for depression?
•
• Correct Answer: A. SSRI
• Rationale: SSRIs (Selective Serotonin Reuptake Inhibitors) are first-line because
they have a favorable efficacy profile, are generally safe in overdose, and have fewer
severe side effects compared to older classes like Tricyclic Antidepressants (TCAs) or
MAOIs.
•
3. When treating a patient for major depression disorder which medication would
the PMHNP consider first?
•
• Correct Answer: C. Escitalopram
• Rationale: Escitalopram is an SSRI, making it a first-line treatment option. The other
options are either mood stabilizers (Depakote) or MAOIs (Selegiline, Isocarboxazid),
which are reserved for treatment-resistant cases due to dietary restrictions and drug
interactions.
•
4. Which of the following medication should be considered for a patient diagnosed
with major depressive disorder who reports "always forgetting to take my pills"?
•
• Correct Answer: C. Fluoxetine
2
, • Rationale: Fluoxetine has a exceptionally long half-life (and an active metabolite,
norfluoxetine, with a half-life of up to two weeks). This means missing a single dose or
occasionally skipping a day has a minimal impact on plasma levels, making it ideal for
non-compliant patients.
•
5. Which medication is considered the best tolerated SSRI?
•
• Correct Answer: D. Escitalopram
• Rationale: Escitalopram is the pure S-enantiomer of citalopram. It is known for
having minimal drug-drug interactions (low CYP450 enzyme inhibition) and a clean side-
effect profile, making it clinically recognized as one of the best-tolerated SSRIs.
•
6. During a 4 week follow up appointment, Rashida, who is prescribed Sertraline
25mg qAM reports slight improvement in depression symptoms and tolerating
medication well. Which of the following should the PMHNP do?
•
• Correct Answer: A. Increase Setraline dose
• Rationale: Sertraline 25mg is an initial starting dose. Since Rashida is tolerating it
well and showing only slight improvement at 4 weeks, the standard clinical protocol is to
titrate up toward a therapeutic target dose (e.g., 50mg–100mg) to maximize symptom
remission.
•
7. A patient reports upset stomach and diarrhea 3 days after taking new
prescription of sertraline. Which of the following is the most appropriate response
from the PMHNP?
•
• Correct Answer: B. "Most side effects subside after 4-5 days. Your body is getting
adjusted to the increased serotonin levels".
• Rationale: Sertraline significantly increases serotonin, and because the majority of
serotonin receptors are located in the gastrointestinal tract, transient GI side effects
(nausea, diarrhea) are very common. Patients should be reassured that these symptoms
typically resolve within the first week as receptors downregulate.
•
3
, 8. During a 2 week follow up appointment, the patient reports no improvement in
depressive symptoms with escitalopram. Which of the following statement made
by the PMHNP is correct?
•
• Correct Answer: B. "It can take up to 6 weeks before you notice improvements of
depressive symptoms".
• Rationale: Antidepressants require time to induce neuroplastic changes and receptor
downregulation. While partial improvements can happen sooner, a full clinical trial for
an SSRI takes 4 to 6 weeks at a therapeutic dose. Discontinuing or doubling the dose
at week 2 is premature.
•
9. Duloxetine effects which two neurotransmitters?
•
• Correct Answer: A. serotonin and norepinephrine
• Rationale: Duloxetine belongs to the SNRI (Serotonin-Norepinephrine Reuptake
Inhibitor) drug class, meaning its mechanism of action is dual inhibition of both the
serotonin transporter (SERT) and the norepinephrine transporter (NET).
•
10. Which SSRI has a mild antihistamine effect?
•
• Correct Answer: C. Citalopram
• Rationale: Citalopram possesses mild histamine H1 receptor antagonist properties,
which can sometimes contribute to mild sedating effects compared to more activating
SSRIs like fluoxetine.
•
11. Which medication should the PMHNP prescribe for a patient diagnosed with
major depressive disorder but takes multiple medications for other chronic
conditions?
•
• Correct Answer: B. Escitalopram
• Rationale: Escitalopram has virtually no significant inhibition of Cytochrome P450
enzymes. This means it carries the lowest risk of drug-drug interactions, making it
the safest profile for a patient on polypharmacy for chronic medical issues.
