Introduction
The NR 546 Midterm Examination assesses advanced
psychopharmacologic knowledge and clinical prescribing
judgment for psychiatric-mental health nurse practitioners. It
evaluates neurobiology, neurotransmitter systems,
pharmacokinetics, pharmacodynamics, and evidence-based
medication management across depressive, bipolar, psychotic,
anxiety, attention, and substance use disorders. Candidates must
apply therapeutic reasoning, identify adverse effects and
interactions, monitor laboratory and clinical responses, and make
,safe prescribing decisions. Multiple-choice and scenario-based
items emphasize real-world application, ethical practice, legal
compliance, and individualized care. The examination requires
foundational theory, applied professional knowledge, critical
thinking, and defensible clinical decision-making for diverse
patient populations.
Section One: Questions 1–100
1. Which neurotransmitter is most strongly implicated in
the positive symptoms of schizophrenia?
A. GABA
B. Dopamine
C. Serotonin
D. Acetylcholine
Correct answer: B
RATIONALE: Positive symptoms of schizophrenia, such as
hallucinations and delusions, are most strongly associated with
increased dopaminergic activity in mesolimbic pathways.
Antipsychotics that block dopamine D2 receptors reduce these
symptoms.
2. Which triad is most characteristic of serotonin
syndrome?
A. Bradycardia, hypotension, and hypothermia
B. Constipation, bradycardia, and sedation
C. Dry mouth, urinary retention, and blurred vision
D. Altered mental status, autonomic instability, and
neuromuscular abnormalities
Correct answer: D
, RATIONALE: Serotonin syndrome classically presents with
altered mental status, autonomic instability, and neuromuscular
abnormalities such as clonus, hyperreflexia, and rigidity. It is a
medical emergency.
3. Which class of medication is generally considered first-
line for major depressive disorder?
A. Selective serotonin reuptake inhibitors
B. Tricyclic antidepressants
C. Monoamine oxidase inhibitors
D. Benzodiazepines
Correct answer: A
RATIONALE: SSRIs are first-line for major depressive disorder
because of their favorable efficacy, safety, and tolerability
compared with older antidepressants.
4. What is the black box warning associated with
antidepressant use in children and young adults?
A. Increased risk of hypertension
B. Increased risk of weight gain
C. Increased risk of suicidal thinking and behavior
D. Increased risk of renal failure
Correct answer: C
RATIONALE: Antidepressants carry a black box warning for
increased risk of suicidal thinking and behavior in children,
adolescents, and young adults, especially during initiation and
dose changes.
5. Which adverse effect is commonly associated with
SSRIs and often leads to nonadherence?
, A. Bradycardia
B. Sexual dysfunction
C. Hyperkalemia
D. Weight loss
Correct answer: B
RATIONALE: Sexual dysfunction, including decreased libido,
delayed ejaculation, and anorgasmia, is a common SSRI adverse
effect that can affect adherence.
6. Which medication is used as an antidote for serotonin
syndrome?
A. Naloxone
B. Flumazenil
C. Vitamin K
D. Cyproheptadine
Correct answer: D
RATIONALE: Cyproheptadine is a serotonin antagonist used in
serotonin syndrome when supportive care is insufficient.
Naloxone and flumazenil are antidotes for opioids and
benzodiazepines, respectively.
7. Which symptom cluster is most consistent with SSRI
discontinuation syndrome?
A. Dizziness, flu-like symptoms, and paresthesias
B. Hypertension, tachycardia, and diaphoresis
C. Bradycardia, constipation, and hypothermia
D. Weight gain, sedation, and hyperphagia
Correct answer: A
RATIONALE: SSRI discontinuation syndrome commonly causes
dizziness, nausea, flu-like symptoms, paresthesias, and
