,Q1. A nurse is caring for a patient who has been taking a selective serotonin reuptake inhibitor (SSRI) for 6
weeks with no improvement in depressive symptoms. The patient's serum serotonin level is within normal
limits. Which neurobiological mechanism best explains the lack of therapeutic response?
A. Downregulation of postsynaptic 5-HT1A receptors
B. Polymorphism in the serotonin transporter gene (SLC6A4)
C. Insufficient dietary tryptophan intake reducing serotonin synthesis
D. Competitive antagonism at the 5-HT2C receptor
Correct Answer: B. Polymorphism in the serotonin transporter gene (SLC6A4)
Rationale: The most likely cause of SSRI non-response is a genetic polymorphism in the serotonin transporter gene
(SLC6A4), specifically the short allele of the 5-HTTLPR, which reduces transporter availability and impairs SSRI
efficacy. Downregulation of postsynaptic receptors (A) is a normal adaptive response, not a cause of non-response.
Tryptophan deficiency (C) is rare in developed countries. 5-HT2C antagonism (D) is associated with some atypical
antidepressants but not SSRI failure.
Why Wrong:
A - Downregulation of 5-HT1A receptors occurs with chronic SSRI use and is associated with therapeutic
response, not failure.
C - Tryptophan deficiency is uncommon and would affect all serotonergic pathways, not just SSRI response.
D - 5-HT2C antagonism is a property of some antidepressants (e.g., mirtazapine) but not a mechanism of
SSRI non-response.
Reference: Stahl, S. M. (2021). Stahl's Essential Psychopharmacology, 5th Ed., Ch. 6.
Q2. A patient with borderline personality disorder frequently engages in self-harm by cutting. During a
therapy session, the patient states, "You don't really care about me; you're just here for the paycheck."
Which therapeutic response best aligns with dialectical behavior therapy (DBT) principles?
A. "I understand you feel that way, but my role is to help you, not to argue."
B. "It sounds like you're testing whether I can be trusted. Let's explore what makes you feel I don't care."
C. "I care about my patients, but I need you to focus on using your coping skills instead of accusing me."
D. "Your perception is distorted. I am here because I want to help you."
Correct Answer: B. "It sounds like you're testing whether I can be trusted. Let's explore what makes you feel
I don't care."
Rationale: DBT emphasizes validation, dialectics, and behavioral change. Option B validates the patient's
underlying emotion (distrust) while inviting exploration, balancing acceptance and change. Option A is dismissive.
Option C invalidates the patient's feelings by redirecting. Option D directly contradicts the patient's perception,
which can escalate conflict.
Why Wrong:
A - This response invalidates the patient's feeling and avoids addressing the underlying trust issue.
C - This response dismisses the patient's accusation and may reinforce feelings of invalidation.
D - Directly labeling the patient's perception as distorted is confrontational and not therapeutic in DBT.
Reference: Linehan, M. M. (2015). DBT Skills Training Manual, 2nd Ed., Ch. 4.
Q3. A patient with schizophrenia is receiving clozapine. The nurse notes a sudden onset of sore throat, fever,
and oral ulcers. Which immediate action is most critical?
A. Obtain a throat culture and start broad-spectrum antibiotics
B. Discontinue clozapine and obtain a complete blood count with differential
C. Administer acetaminophen and encourage increased fluid intake
D. Schedule an electrocardiogram to rule out QT prolongation
Correct Answer: B. Discontinue clozapine and obtain a complete blood count with differential
Rationale: Clozapine carries a black box warning for agranulocytosis (absolute neutrophil count <500/¼L). The
triad of sore throat, fever, and oral ulcers is a classic presentation. Immediate discontinuation and CBC with
Page 3
, differential are required to prevent fatal infection. Antibiotics (A) may be needed later but are not the first priority.
Acetaminophen (C) treats symptoms but delays diagnosis. ECG (D) is not indicated for this presentation.
Why Wrong:
A - Antibiotics may be indicated after agranulocytosis is confirmed, but the immediate priority is to stop clozapine and
check the neutrophil count.
C - Symptomatic treatment without addressing the underlying agranulocytosis can be dangerous.
D - QT prolongation is a risk with other antipsychotics but not the immediate concern here.
Reference: Lehne, R. A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 29.
Q4. A nurse is assessing a patient who reports a history of multiple suicide attempts and current suicidal
ideation with a plan. The patient's affect is flat, and they state, "Nothing matters anymore." Using the
Columbia-Suicide Severity Rating Scale (C-SSRS), which category best describes the patient's current risk
level?
A. Passive suicidal ideation without intent
B. Active suicidal ideation with method, intent, and plan
C. Active suicidal ideation with method and plan, but no intent
D. Suicidal behavior with aborted attempt
Correct Answer: B. Active suicidal ideation with method, intent, and plan
Rationale: The patient expresses current suicidal ideation with a plan (method and plan) and reports multiple past
attempts, indicating high intent. The C-SSRS classifies active suicidal ideation with specific plan and intent as the
highest risk category (Category 5). Passive ideation (A) lacks a plan. Option C lacks intent. Option D refers to past
behavior, not current ideation.
Why Wrong:
A - Passive ideation involves thoughts of death without a plan or intent, which is lower risk.
C - The patient's statement "nothing matters" and history of attempts imply intent, not just a plan.
D - Aborted attempt refers to an interrupted attempt, not current ideation.
Reference: Posner, K., et al. (2011). Columbia-Suicide Severity Rating Scale (C-SSRS).
Q5. A patient with bipolar I disorder is stabilized on lithium carbonate. The nurse reviews laboratory results:
serum lithium 0.9 mEq/L, TSH 6.2 IU/mL (normal 0.4-4.0), creatinine 1.1 mg/dL. Which nursing
intervention is most appropriate?
A. Hold the next lithium dose and notify the provider of potential toxicity
B. Administer lithium as ordered and document the findings
C. Administer lithium and request a thyroid panel including free T4
D. Administer lithium with a low-sodium diet to enhance therapeutic effect
Correct Answer: C. Administer lithium and request a thyroid panel including free T4
Rationale: Lithium can cause hypothyroidism (elevated TSH) even at therapeutic levels (0.6-1.2 mEq/L). The TSH
of 6.2 indicates subclinical hypothyroidism, which requires further evaluation (free T4) and possibly thyroid
hormone replacement. Lithium level is therapeutic, so holding it (A) is not indicated. Simply documenting (B)
ignores the abnormality. Low-sodium diet (D) can increase lithium levels and risk toxicity.
Why Wrong:
A - Lithium level is within therapeutic range; toxicity is not present.
B - The elevated TSH requires action; documenting alone is insufficient.
D - Low-sodium diet increases lithium reabsorption and risk of toxicity; not recommended.

Bipolar Disorder, 3rd Ed.
Q6. A nurse is providing education to a patient newly prescribed phenelzine, a monoamine oxidase inhibitor
(MAOI). Which statement by the patient indicates a need for further teaching?
