NR565 Advanced Pharmacology Fundamentals
Exam 4 v3 Questions with Correct Answers and
Expert Explanation for Each Question
1. A patient is starting Sertraline (Zoloft) for the treatment of Major Depressive
Disorder. Which of the following is the most important educational point regarding
the onset of action?
A. The patient will feel significant relief within the first 48 hours of treatment.
B. The medication should be stopped immediately if no change is felt in one week.
C. Optimal therapeutic effects typically take 4 to 6 weeks to manifest.
D. The drug only works when taken on an as-needed basis for acute sadness.
Correct Answer: C
Expert Explanation: SSRIs like Sertraline do not provide immediate relief from
depressive symptoms. It is critical for the provider to manage expectations by
explaining that physiological changes occur over several weeks. Educating the
patient on this timeline improves adherence and prevents premature
discontinuation of the medication.
,2. When prescribing a Selective Serotonin Reuptake Inhibitor (SSRI), the nurse
practitioner must warn the patient about ‘Black Box’ warnings. What is the primary
concern for patients under 24?
A. Increased risk of hepatotoxicity and liver failure.
B. Development of severe cardiac arrhythmias.
C. Rapid onset of Type 2 Diabetes Mellitus.
D. Increased risk of suicidal ideation and behavior.
Correct Answer: D
Expert Explanation: The FDA has issued a Black Box warning for all
antidepressants regarding the increased risk of suicidal thoughts in children,
adolescents, and young adults. This risk is highest during the first few weeks of
therapy or following dose adjustments. Close monitoring for behavioral changes or
worsening mood is mandatory in this population.
3. A patient taking Phenelzine (Nardil) for depression attends a party and consumes
aged cheese and red wine. Which clinical emergency should the provider anticipate?
A. Serotonin Syndrome.
B. Neuroleptic Malignant Syndrome.
C. Hypoglycemic Shock.
,D. Hypertensive Crisis.
Correct Answer: D
Expert Explanation: Phenelzine is a Monoamine Oxidase Inhibitor (MAOI) that
prevents the breakdown of tyramine. Consuming high-tyramine foods like aged
cheese and wine leads to massive release of norepinephrine, causing severe
vasoconstriction. This result is a hypertensive crisis which can lead to stroke or
myocardial infarction if not treated.
4. Which of the following physical findings is a hallmark sign of Serotonin Syndrome
that distinguishes it from other toxidromes?
A. Hypothermia and bradycardia.
B. Lead-pipe muscle rigidity.
C. Hyperreflexia and myoclonus.
D. Pinpoint pupils and respiratory depression.
Correct Answer: C
Expert Explanation: Serotonin Syndrome is characterized by neuromuscular
excitability, including hyperreflexia and clonus, particularly in the lower extremities.
This differs from Neuroleptic Malignant Syndrome, which is typically associated
with ‘lead-pipe’ rigidity and slower onset. Prompt recognition of these
neuromuscular signs is essential for life-saving intervention.
, 5. A patient with a history of seizures requires an antidepressant. Which medication is
strictly contraindicated due to its potential to lower the seizure threshold?
A. Fluoxetine.
B. Venlafaxine.
C. Bupropion.
D. Duloxetine.
Correct Answer: C
Expert Explanation: Bupropion is known to significantly lower the seizure
threshold, especially at higher doses or in patients with pre-existing seizure
disorders. It is also contraindicated in patients with eating disorders like bulimia or
anorexia due to increased seizure risk. Providers should screen for these conditions
before initiating treatment with this aminoketone.
6. A provider is considering Venlafaxine (Effexor) for a patient. Which baseline
assessment is most critical for this Selective Norepinephrine Reuptake Inhibitor
(SNRI)?
A. Liver function tests.
B. Ophthalmic exam.
C. Blood pressure.
