1.
A psychiatric mental health nurse practitioner is evaluating a
patient who has recently been diagnosed with major depressive
disorder. The patient reports persistent sadness, anhedonia,
decreased energy, difficulty concentrating, and disrupted sleep
occurring nearly every day. The provider is discussing how
antidepressant medications produce therapeutic effects and
explains that clinical improvement generally does not occur
immediately after neurotransmitter levels change. Which
explanation most accurately describes the delayed therapeutic
response associated with many antidepressant medications?
A. Antidepressants immediately replace depleted serotonin
stores, producing an instant antidepressant effect.
B. Antidepressants permanently increase the number of
neurotransmitter receptors within several hours.
C. Antidepressants initiate neurochemical changes
that are followed by downstream receptor, signaling,
and neuroplastic adaptations that develop over time.
D. Antidepressants work primarily by increasing dopamine
metabolism within the first few minutes after administration.
,Correct Answer: C
Rationale: Although many antidepressants alter
neurotransmitter availability relatively quickly, improvement
in depressive symptoms usually takes longer because
downstream receptor signaling, neuronal adaptation, and
neuroplastic changes develop gradually.
2.
A patient beginning treatment with an SSRI asks the psychiatric
nurse practitioner why the medication must be taken
consistently even though the patient has not noticed
improvement after several days. The patient states, “If it hasn't
worked by now, I don't think it's going to work.” Which
response best explains the expected pharmacologic course?
A. SSRIs generally produce their complete therapeutic effect
within 24 hours.
B. The patient should double the dose whenever improvement
is not noticed within three days.
C. SSRIs only work when taken on an as-needed basis during
periods of depression.
D. The medication may begin altering serotonin
signaling early, but meaningful symptom
improvement commonly requires several weeks of
continued treatment.
Correct Answer: D
Rationale: Antidepressant treatment requires consistent
administration because clinical benefits often emerge
gradually. Early lack of improvement does not necessarily
indicate treatment failure.
3.
,A patient taking an SSRI for depression returns to the clinic
approximately two weeks after starting therapy. The patient
reports mild nausea and headache but says depressive
symptoms have not significantly improved. The patient wants
to discontinue the medication immediately because of the lack
of improvement. Which action by the PMHNP is most
appropriate?
A. Immediately discontinue the medication because SSRIs
should work within several days.
B. Increase the medication to the maximum dose without
further assessment.
C. Assess tolerability, safety, adherence, and symptom
trajectory while explaining that antidepressant
response may require additional time.
D. Tell the patient that side effects indicate that the medication
is ineffective.
Correct Answer: C
Rationale: Early adverse effects can occur before
therapeutic benefits become evident. The clinician should
assess safety and adherence and provide appropriate
expectations regarding the time course of antidepressant
response.
4.
A patient prescribed an SSRI contacts the psychiatric clinic and
reports severe agitation, confusion, sweating, diarrhea, tremor,
and muscle rigidity after recently starting another serotonergic
medication. The nurse recognizes that the combination may
have produced excessive serotonergic activity. Which condition
should the nurse suspect?
A. Neuroleptic malignant syndrome
B. Anticholinergic toxicity
, C. Lithium toxicity
D. Serotonin syndrome
Correct Answer: D
Rationale: Serotonin syndrome may occur with excessive
serotonergic activity and can include mental-status changes,
autonomic instability, gastrointestinal symptoms, tremor,
hyperreflexia, and neuromuscular abnormalities.
5.
A patient taking an SSRI develops fever, marked autonomic
instability, agitation, hyperreflexia, and clonus shortly after
another serotonergic medication is added. The PMHNP
determines that serotonin toxicity is likely. Which intervention
is the priority?
A. Continue both medications and reassess in one week.
B. Discontinue the offending serotonergic agents and
provide appropriate supportive and urgent medical
management.
C. Increase the SSRI dose to stabilize serotonin receptors.
D. Administer another serotonergic antidepressant.
Correct Answer: B
Rationale: Suspected serotonin syndrome is a potentially
serious medication reaction requiring prompt discontinuation
of causative serotonergic agents and appropriate supportive
care.
6.
A patient taking an antidepressant reports decreased libido and
difficulty achieving orgasm since beginning treatment. The
patient states that these symptoms are causing significant
