Walden University NURS 6670 Final Exam (pdf) | 2026/2027 | PMHNP
Q&A |
1. Which of the following best describes the primary focus of the PMHNP role
when working with older adults?
A) Providing supportive therapy exclusively
B) Managing polypharmacy and age-related physiological changes
C) Focusing solely on cognitive behavioral interventions
D) Prescribing only non-pharmacological treatments
Correct Answer: Managing polypharmacy and age-related physiological
changes
Rationale: The PMHNP role with older adults requires careful management of
polypharmacy due to multiple comorbidities and age-related changes in
pharmacokinetics and pharmacodynamics. This population is particularly
vulnerable to adverse drug reactions and drug interactions. Supportive
therapy alone or exclusive focus on any single modality does not address the
comprehensive needs of this population.
2. A 68-year-old patient with a history of hypertension and type 2 diabetes
presents with new-onset depressive symptoms. What is the most appropriate
initial step for the PMHNP?
A) Immediately prescribe an SSRI at a standard adult dose
B) Order a comprehensive metabolic panel and thyroid function tests
C) Refer the patient for electroconvulsive therapy
D) Recommend over-the-counter St. John's wort
Correct Answer: Order a comprehensive metabolic panel and thyroid function
tests
,Rationale: In older adults, new-onset depressive symptoms may result from
underlying medical conditions such as hypothyroidism, electrolyte
imbalances, or uncontrolled diabetes. A thorough medical workup is essential
before initiating psychiatric treatment. SSRIs should be started at lower
doses in older adults, and ECT is typically reserved for treatment-resistant
cases.
3. According to the biopsychosocial model, which factor is most relevant
when assessing an adult patient with anxiety?
A) Genetic predisposition only
B) Social support systems and environmental stressors
C) Neurotransmitter imbalances exclusively
D) Childhood trauma as the sole determinant
Correct Answer: Social support systems and environmental stressors
Rationale: The biopsychosocial model integrates biological, psychological,
and social factors in understanding mental health conditions. Social support
systems and environmental stressors are key psychosocial components that
influence the presentation and course of anxiety disorders. Genetic and
neurobiological factors are important but do not alone explain the complexity
of anxiety disorders.
4. What is the primary purpose of a mental status examination (MSE) in
psychiatric assessment?
A) To diagnose specific personality disorders
B) To provide a structured observation of the patient's current cognitive and
emotional functioning
C) To determine the patient's IQ score
D) To assess the patient's medical history
,Correct Answer: To provide a structured observation of the patient's current
cognitive and emotional functioning
Rationale: The MSE is a systematic assessment tool that evaluates
appearance, behavior, speech, mood, affect, thought process, thought
content, perception, cognition, insight, and judgment. It provides a snapshot
of the patient's current mental state rather than diagnosing specific
disorders. The MSE guides clinical decision-making and treatment planning.
5. Which neurotransmitter system is primarily targeted by selective serotonin
reuptake inhibitors (SSRIs)?
A) Dopamine
B) Norepinephrine
C) Serotonin
D) GABA
Correct Answer: Serotonin
Rationale: SSRIs work by blocking the reuptake of serotonin at the synaptic
cleft, increasing serotonin availability for neurotransmission. This mechanism
is effective for depression, anxiety disorders, and other conditions. SSRIs
have minimal effect on dopamine or norepinephrine reuptake compared to
other antidepressant classes.
6. A researcher is studying the efficacy of cognitive behavioral therapy for
panic disorder. Which outcome measure would be most appropriate?
A) Blood pressure readings
B) Panic Attack Severity Scale scores
C) Complete blood count results
D) Electroencephalogram findings
, Correct Answer: Panic Attack Severity Scale scores
Rationale: The Panic Attack Severity Scale is a validated instrument
specifically designed to measure panic attack frequency, intensity, and
associated distress. It directly assesses the core symptoms of panic disorder.
Physiological measures like blood pressure or EEG do not specifically
measure panic severity, and CBC is unrelated to panic disorder assessment.
7. Which term refers to the therapeutic communication technique of
reflecting the patient's feelings back to them?
A) Validation
B) Clarification
C) Paraphrasing
D) Confrontation
Correct Answer: Validation
Rationale: Validation involves acknowledging and accepting the patient's
emotional experience without judgment. It helps patients feel understood
and builds therapeutic rapport. Clarification seeks to understand ambiguous
statements, paraphrasing restates content, and confrontation points out
discrepancies.
8. What is the most likely outcome if a patient with bipolar disorder abruptly
discontinues lithium therapy?
A) Immediate remission of symptoms
B) Increased risk of manic relapse
C) Permanent cure of the disorder
D) Development of serotonin syndrome
