DISCLAIMER:
This material consists of original practice questions developed for educational
preparation purposes. It is not the actual ANCC PMHNP certification
examination and does not reproduce confidential examination content.
Questions are based on general exam domains, commonly tested subject areas,
,professional standards, clinical concepts, and educational resources used for
certification preparation.
QUESTION 1.
A 42-year-old patient with bipolar I disorder presents for follow-up after
experiencing a manic episode three months ago. The patient reports improved
mood stability while taking lithium but states that they have started a strict
low-sodium diet and increased endurance exercise training. Laboratory results
show a lithium level at the upper end of the therapeutic range. Which
intervention by the psychiatric-mental health nurse practitioner (PMHNP) is the
highest priority?
A. Increase lithium dosage to maintain stronger mood stabilization
B. Educate the patient that sodium restriction and dehydration may increase
lithium toxicity risk
C. Discontinue lithium immediately and transition to an atypical antipsychotic
D. Recommend eliminating physical exercise until lithium therapy is completed
🔴 Correct Answer: B. Educate the patient that sodium restriction and
dehydration may increase lithium toxicity risk
🔵 Explanation: Lithium concentrations are significantly influenced by renal
sodium handling and hydration status. A low-sodium diet and increased
sweating from endurance exercise can reduce lithium clearance and increase
toxicity risk. Lithium should not be automatically discontinued, and exercise
restrictions are unnecessary if hydration and monitoring are appropriately
managed.
QUESTION 2.
A 29-year-old patient presents with persistent depressive symptoms, including
low energy, insomnia, impaired concentration, and feelings of worthlessness.
The patient denies suicidal ideation but reports a history of recurrent depressive
episodes separated by periods of complete remission. Which clinical finding
would most strongly support a diagnosis of recurrent major depressive disorder
rather than persistent depressive disorder?
A. Symptoms lasting more than two years without remission
B. Presence of chronic low self-esteem and hopelessness
,C. Distinct episodes with full return to baseline functioning between episodes
D. Depressive symptoms occurring primarily during winter months
🔴 Correct Answer: C. Distinct episodes with full return to baseline
functioning between episodes
🔵 Explanation: Recurrent major depressive disorder is characterized by
separate depressive episodes with periods of remission or recovery between
episodes. Persistent depressive disorder involves a chronic depressed mood
occurring most of the time for at least two years. Seasonal patterns may modify
depressive disorders but do not specifically distinguish recurrent major
depression from persistent depressive disorder.
QUESTION 3.
A PMHNP evaluates a patient taking clozapine who develops fever, sore throat,
and malaise. The patient's absolute neutrophil count has decreased significantly
from previous monitoring results. Which action should the PMHNP prioritize?
A. Assess for neutropenia-related complications and follow clozapine
monitoring protocols
B. Increase the clozapine dose because symptoms indicate infection resistance
C. Add an antidepressant to improve treatment adherence
D. Continue medication without intervention because mild symptoms are
expected
🔴 Correct Answer: A. Assess for neutropenia-related complications and
follow clozapine monitoring protocols
🔵 Explanation: Clozapine carries a serious risk of agranulocytosis and
requires ongoing hematologic monitoring. Fever and sore throat may indicate
neutropenia requiring immediate evaluation and appropriate action. Increasing
the medication or ignoring symptoms may place the patient at significant
medical risk.
QUESTION 4.
A 67-year-old patient with generalized anxiety disorder reports increasing
confusion, dizziness, and falls after beginning treatment with a new anxiolytic
, medication. The patient has no evidence of infection or metabolic abnormalities.
Which medication-related concern should the PMHNP consider most strongly?
A. Increased dopamine activity causing psychosis
B. Anticholinergic burden and sedative effects contributing to cognitive
impairment
C. Excessive serotonin production causing mania
D. Reduced medication absorption due to aging
🔴 Correct Answer: B. Anticholinergic burden and sedative effects
contributing to cognitive impairment
🔵 Explanation: Older adults are particularly vulnerable to medications with
anticholinergic and sedative properties, which can worsen cognition, increase
fall risk, and contribute to delirium-like symptoms. Medication selection in
geriatric psychiatry requires careful evaluation of risk-benefit considerations.
The other options do not best explain the patient's presentation.
QUESTION 5.
A 19-year-old college student presents with decreased need for sleep,
grandiosity, pressured speech, impulsive spending, and increased goal-directed
activity lasting 10 days. The patient denies hallucinations and maintains
academic functioning despite behavioral changes. Which diagnostic
consideration is most appropriate?
A. Adjustment disorder with anxiety
B. Cyclothymic disorder
C. Bipolar I disorder, current manic episode
D. Generalized anxiety disorder
🔴 Correct Answer: C. Bipolar I disorder, current manic episode
🔵 Explanation: A manic episode lasting at least one week with elevated or
irritable mood and associated symptoms causing significant behavioral change
supports bipolar I disorder. Psychotic symptoms are not required for diagnosis.
Cyclothymic disorder involves chronic fluctuating symptoms that do not meet
criteria for full manic episodes.
